BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Business Overview and Organization Omega Healthcare Investors, Inc. (“Parent”) is a Maryland corporation that, together with its consolidated subsidiaries (collectively, “Omega,” the “Company,” “we,” “our,” or “us”) invests in healthcare-related real estate properties located in the United States (“U.S.”) and the United Kingdom (“U.K.”). Our core business is to provide financing and capital to the long-term healthcare industry with a particular focus on skilled nursing facilities (“SNFs”), assisted living facilities (“ALFs”), and to a lesser extent, independent living facilities (“ILFs”), rehabilitation and acute care facilities (“specialty facilities”) and medical office buildings. Our core portfolio consists of long-term “triple net” leases and mortgage loans with healthcare operating companies and affiliates (collectively, our “operators”). In addition to our core investments, we make loans to operators and/or their principals. From time to time, we also acquire equity interests in joint ventures or entities that support the long-term healthcare industry and our operators. Omega has elected to be taxed as a real estate investment trust (“REIT”) for federal income tax purposes and is structured as an umbrella partnership REIT (“UPREIT”) under which all of Omega’s assets are owned directly or indirectly by, and all of Omega’s operations are conducted directly or indirectly through, its operating partnership subsidiary, OHI Healthcare Properties Limited Partnership (collectively with its subsidiaries, “Omega OP”). Omega has exclusive control over Omega OP’s day-to-day management pursuant to the partnership agreement governing Omega OP. As of June 30, 2022, Parent owned approximately 97% of the issued and outstanding units of partnership interest in Omega OP (“Omega OP Units”), and other investors owned approximately 3% of the outstanding Omega OP Units. Basis of Presentation and Principles of Consolidation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and notes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the interim periods reported herein are not necessarily indicative of results to be expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the financial statements and the footnotes thereto included in our latest Annual Report on Form 10-K Omega’s consolidated financial statements include the accounts of (i) Parent, (ii) all direct and indirect wholly owned subsidiaries of Omega, including Omega OP, (iii) other entities in which Omega or Omega OP has a majority voting interest and control and (iv) variable interest entities (“VIEs”) of which Omega is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation, and Omega’s net earnings are reduced by the portion of net earnings attributable to noncontrolling interests. Segments We conduct our operations and report financial results as one business segment. The presentation of financial results as one reportable segment is consistent with the way we operate our business and is consistent with the manner in which our Chief Operating Decision Maker (CODM), our Chief Executive Officer, evaluates performance and makes resource and operating decisions for the business. Reclassification Certain line items on our Consolidated Balance Sheets and Consolidated Statements of Cash Flows have been reclassified to conform to the current period presentation. Risks and Uncertainties including COVID-19 The Company is subject to certain risks and uncertainties affecting the healthcare industry, including those stemming from the novel coronavirus (“COVID-19”) global pandemic described below, which has disproportionately impacted the senior care sector, as well as those stemming from healthcare legislation and changing regulation by federal, state and local governments. Additionally, we are subject to risks and uncertainties as a result of changes affecting operators of nursing home facilities due to the actions of governmental agencies and insurers to limit the rising cost of healthcare services. Recent Accounting Pronouncements ASU – 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures On March 31, 2022, the FASB issued ASU 2022-02, which eliminates the recognition and measurement guidance for troubled debt restructurings (“TDRs”) and requires additional disclosures for certain loan modifications. ASU 2022-02 also requires entities to disclose gross write-offs of financing receivables and net investments in leases by year of origination. Omega elected to early adopt ASU 2022-02 on a prospective basis effective January 1, 2022. In the second quarter of 2022, we had one loan modification to a borrower experiencing financial difficulty pursuant to ASU 2022-02, Guardian Healthcare (“Guardian”), that requires additional disclosures. The required disclosures for this loan are included in Note 4 – Contractual Receivables and Other Receivables and Lease Inducements and Note 5 – Mortgage Notes Receivable. We have disclosed our gross write-offs of financing receivables and direct financing leases by year of origination in Note 7 – Allowance for Credit Losses. ASU – 2020-04, Financial Instruments – Reference Rate Reform (Topic 848) On March 12, 2020, the FASB issued ASU 2020-04, which contains optional practical expedients for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting for contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”). The guidance may be elected over time until December 31, 2022, as reference rate reform activities occur. The Company has several derivative instruments (See Note 16 – Derivatives and Hedging), a $1.45 billion senior unsecured multicurrency revolving credit facility, and a $50.0 million senior unsecured term loan facility (See Note 15 – Borrowing Activities and Arrangements) that reference LIBOR. We also have a $25.0 million senior secured debtor-in-possession (“DIP”) facility loan with an operator that references LIBOR (See Note 6 – Other Investments), but it matures in 2022 prior to LIBOR being discontinued. During the first quarter of 2020, we elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. Our credit facilities that reference LIBOR contain customary LIBOR replacement language, including, but not limited to, the use of rates based on the secured overnight financing rate. The Company continues to evaluate: (i) how the transition away from LIBOR will impact the Company, (ii) whether any additional optional expedients provided by the standards will be adopted, and (iii) the impact that adopting ASU 2020-04 will have on our consolidated financial statements.

ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS [Abstract]
ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS	NOTE 3 – ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS Periodically we sell facilities to reduce our exposure to certain operators, geographies and non-strategic assets or due to the exercise of a tenant purchase option. The following is a summary of our assets held for sale: ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2022 2021 Number of facilities held for sale ​ 15 ​ ​ 41 Amount of assets held for sale (in thousands) $ 61,624 ​ $ 261,151 ​ Asset Sales During the three and six months ended June 30, 2022, we sold 13 and 40 facilities, subject to operating leases, for approximately $54.3 million and $386.9 million in net cash proceeds, recognizing net gains of approximately $25.2 million and $138.8 million, respectively. The proceeds and gain for the six months ended June 30, 2022 primarily relate to the sale of the 22 facilities in the first quarter of 2022 that were previously leased and operated by Gulf Coast Health Care LLC (together with certain affiliates “Gulf Coast”) and were included in assets held for sale as of December 31, 2021. The net cash proceeds from the sale, including related costs accrued for as of the end of the second quarter, were $304.0 million, and we recognized a net gain of approximately $113.5 million. We elected to exit these facilities following Gulf Coast commencing its Chapter 11 bankruptcy process in October 2021. The agreement includes an earnout clause pursuant to which the buyer is obligated to pay an additional $18.7 million to Omega if certain financial metrics are achieved at the facilities in the three years following the sale. As we have determined it is not probable that we will receive any additional funds, we have not recorded any income related to the earnout clause. We also sold nine facilities (two facilities in the first quarter and seven in the second quarter) during the six months ended June 30, 2022 that were previously leased to Guardian for $39.5 million in net proceeds, which resulted in a net gain of approximately $13.7 million. The sales were in connection with the restructuring of Guardian’s portfolio. One of the facilities sold in the first quarter of 2022 was sold to the joint venture that was consolidated in the first quarter of 2022, as discussed further in Note 8 – Variable Interest Entities. Real Estate Impairments During the three and six months ended June 30, 2022, we recorded impairments on four and six facilities of approximately $7.7 million and $11.2 million, respectively. Of the $11.2 million, $3.5 million related to two facilities that were classified as held for sale for which the carrying values exceeded the estimated fair values less costs to sell, and $7.7 million related to four held-for-use facilities for which the carrying value exceeded the fair value. To estimate the fair value of the facilities for the impairments noted above, we utilized a market approach that considered binding sale agreements (a Level 1 input), or non-binding offers from unrelated third parties and/or broker quotes (a Level 3 input).

CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS [Abstract]
CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS	NOTE 4 – CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS Contractual receivables relate to the amounts currently owed to us under the terms of our lease and loan agreements. Effective yield interest receivables relate to the difference between the interest income recognized on an effective yield basis over the term of the loan agreement and the interest currently due to us according to the contractual agreement. Straight-line rent receivables relate to the difference between the rental revenue recognized on a straight-line basis and the amounts currently due to us according to the contractual agreement. Lease inducements result from value provided by us to the lessee, at the inception, modification or renewal of the lease, and are amortized as a reduction of rental income over the non-cancellable lease term. A summary of our net receivables and lease inducements by type is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2022 2021 ​ ​ (in thousands) ​ Contractual receivables – net ​ $ 10,357 ​ $ 11,259 ​ ​ ​ ​ ​ ​ ​ ​ ​ Effective yield interest receivables ​ $ 7,410 ​ $ 9,590 ​ Straight-line rent receivables ​ 172,699 ​ 148,455 ​ Lease inducements ​ 89,904 ​ 93,770 ​ Other receivables and lease inducements ​ $ 270,013 ​ $ 251,815 ​ ​ Agemo Holdings, LLC Agemo Holdings, LLC (“Agemo”) continued to not pay contractual rent and interest due under its lease and loan agreements during the first and second quarters of 2022. Our lease payments from Agemo are on a cash basis of revenue recognition for lease purposes, so no rental income was recorded related to Agemo during the three and six months ended June 30, 2022. Additionally, no interest income was recognized during the three and six months ended June 30, 2022 on the two loans with Agemo because these loans are on non-accrual status and we are utilizing the cost recovery method, under which any payments received are applied against the principal amount. See Note 6 – Other Investments. For the three and six months ended June 30, 2021, revenue from Agemo represented approximately 4.9% and 4.7%, respectively, of our total revenues (excluding the impact of write-offs). During the six months ended June 30, 2022, we extended the forbearance period related to Agemo’s defaults under its lease and loan agreements to August 31, 2022. Guardian Healthcare Guardian Healthcare (“Guardian”) did not make rent and interest payments under its lease and loan agreements during the first quarter of 2022 but resumed making contractual rent and interest payments during the second quarter of 2022, in accordance with the restructuring terms discussed further below. Our lease payments from Guardian are on a cash basis of revenue recognition for lease purposes and we recorded rental income of $3.8 million for the three months ended June 30, 2022 for contractual rent payments that were made. Additionally, as discussed further in Note 5 – Mortgage Notes Receivable, no mortgage interest income has been recognized on the Guardian mortgage loan during the three and six months ended June 30, 2022 as we are accounting for this loan under the cost recovery method. During the first and second quarters of 2022, we completed significant restructuring activities related to the Guardian lease and loan portfolio. In the first quarter of 2022, we transitioned eight facilities previously leased to Guardian to two other operators as part of the planned restructuring. Additionally, during the six months ended June 30, 2022, we sold nine facilities previously leased to Guardian and three facilities previously subject to the Guardian mortgage loan. In the second quarter of 2022, we agreed to a formal restructuring agreement, master lease amendments and mortgage loan amendments with Guardian. As part of the restructuring agreement and related agreements, Omega agreed to, among other terms: ● Extend the lease and loan terms from January 31, 2027 to December 31, 2031 and allow Guardian the option to extend the maturity date for both the lease and loan through September 30, 2034 , subject to certain conditions, ● reduce the combined rent and mortgage interest to an aggregate $24.0 million per year as of July 1, 2022 ( $15.0 million in rent and $9.0 million in interest) with annual escalators of 2.25% beginning in January 2023 and ● allow Guardian to retrospectively defer $18.0 million of aggregate contractual rent and interest that they failed to pay during the period from October 2021 through March 2022 (consisting of $12.2 million of deferred rent and $5.8 of million deferred interest), with repayment required after September 30, 2024 based on certain financial metrics and in full by December 31, 2031, or the earlier termination of the lease for any reason. As of June 30, 2022, we have $7.4 million of letters of credit from Guardian as collateral. Revenue from Guardian represented approximately 1.5% and 3.3% of our total revenues (excluding the impact of straight-line write-offs) for the three months ended June 30, 2022 and 2021, respectively and 0.7% and 3.3% of our total revenues (excluding the impact of straight-line write-offs) for the six months ended June 30, 2022 and 2021, respectively. Other operator updates From January through March 2022, an operator representing 3.8% and 3.4% of total revenue (excluding the impact of write-offs) for both the three months and six months ended June 30, 2022 and 2021, respectively, did not pay its contractual amounts due under its lease agreement. In March 2022, the lease with this operator was amended to allow for a short-term rent deferral for January through March 2022. The deferred rent balance accrues interest monthly at a rate of 5% per annum. This operator paid the contractual amount due under its lease agreement from April 2022 through June 2022. Omega holds a $1.0 million letter of credit and a $150.0 thousand security deposit from this operator. We have provided a $20.0 million revolving credit facility to this operator, and the operator has paid contractual interest under the facility from January through June 2022. As of June 30, 2022, the total outstanding principal due under the credit facility was $20.0 million. The credit facility is secured by a first lien on the operator’s accounts receivable. In March 2022, an operator, representing 1.0% and 2.1% of total revenue (excluding the impact of write-offs) for the three months ended June 30, 2022 and 2021, respectively, and 1.6% and 2.1% of total revenue (excluding the impact of write-offs) for the six months ended June 30, 2022 and 2021, respectively, did not pay its contractual amounts due under its lease agreement. In April 2022, the lease with this operator was amended to allow the operator to apply its $2.0 million security deposit toward payment of March 2022 rent and to allow for a short-term rent deferral for April 2022 with regular rent payments required to resume in May 2022. This operator paid contractual rent in May 2022, but failed to make the full contractual rent payment for June 2022. We placed this operator on a cash basis of revenue recognition during the second quarter of 2022 as collection of substantially all contractual lease payments due from them was no longer deemed probable. As a result, we wrote-off approximately $8.3 million of straight-line rent receivables through rental income. In June 2022, an operator, representing 2.2% and 1.0% of total revenue (excluding the impact of write-offs) for the three months ended June 30, 2022 and 2021, respectively, and 2.2% and 2.1% of total revenue (excluding the impact of write-offs) for the six months ended June 30, 2022 and 2021, respectively, short-paid the contractual rent amount due under its lease agreement by $0.6 million. At June 30, 2022, we held a $5.4 million letter of credit as collateral from this operator. In July 2022, we drew the full amount of the letter of credit and applied $0.6 million of the proceeds to pay the unpaid portion of June rent. We are in discussions with this operator to allow the application of a portion of the remaining proceeds from the letter of credit towards future contractual rent for a short-term period. In June 2022, we placed an operator, representing approximately 0.4% and 0.3% of our total revenues (excluding the impact of write-offs) for the three months ended June 30, 2022 and 2021, respectively, and 0.5% and 0.5% of total revenue (excluding the impact of write-offs) for the six months ended June 30, 2022 and 2021, respectively, on a cash basis of revenue recognition. The change in our evaluation of the collectability of future rent payments due from this operator was as a result of information received from the operator during the second quarter of 2022 regarding substantial doubt as to its ability to continue as a going concern. As a result of placing this operator on a cash basis, we wrote-off approximately $2.1 million of straight-line rent receivables through rental income. All facilities included in this operator’s master lease are included in assets held for sale as of June 30, 2022. During the six months ended June 30, 2022, we allowed three other operators, representing an aggregate 2.3% and 2.7% of total revenue (excluding the impact of write-offs) for the three months ended June 30, 2022 and 2021, respectively, and 2.4% and 2.7% of total revenue (excluding the impact of write-offs) for the six months ended June 30, 2022 and 2021, respectively, to apply an aggregate of $2.2 million of their security deposits to pay rent to accommodate short term liquidity issues, with regular rent payments required to resume shortly thereafter. Additionally, we granted one of these operators a short-term deferral for a portion of its rent due during the six months ended June 30, 2022. As of June 30, 2022, all of these operators are current on their respective lease obligations due to the application of security deposits. These operators also are required to begin replenishing their security deposits in 2023. Other straight-line receivables and write-offs In the first quarter of 2022, we transitioned six facilities between existing operators. The transition resulted in the removal of the facilities from the original operator’s lease agreement and consequently the write-off of $3.2 million of straight-line rent receivable balances through rental income. The facilities were added to the new operator’s lease agreement.

Mortgage Notes Receivable [Abstract]
MORTGAGE NOTES RECEIVABLE	NOTE 5 – MORTGAGE NOTES RECEIVABLE As of June 30, 2022, mortgage notes receivable relate to seven fixed rate mortgage notes on 54 facilities. The mortgage notes are secured by first mortgage liens on the borrowers’ underlying real estate and personal property. The mortgage notes receivable relate to facilities located in six states that are operated by six independent healthcare operating companies. We monitor compliance with the terms of our mortgages and when necessary have initiated collection, foreclosure and other proceedings with respect to certain outstanding mortgage notes. The principal amounts outstanding of mortgage notes receivable, net of allowances, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2022 2021 ​ ​ (in thousands) ​ Mortgage note due 2031; interest at 11.02% ​ $ 80,568 ​ $ 103,762 ​ Mortgage notes due 2030; interest at 10.84% (1) ​ 544,252 ​ 653,564 ​ Other mortgage notes outstanding (2) ​ 150,215 ​ 151,361 ​ Mortgage notes receivable, gross ​ 775,035 ​ 908,687 ​ Allowance for credit losses on mortgage notes receivable ​ (63,446) ​ (73,601) ​ Total mortgage notes receivable — net ​ $ 711,589 ​ $ 835,086 ​ (1) Approximates the weighted average interest rate on 39 facilities as of June 30, 2022. (2) Other mortgage notes outstanding have a weighted average interest rate of 8.85% per annum as of June 30, 2022 and maturity dates ranging from 2023 through 2032 . Mortgage Note due 2031 As discussed in Note 4 – Contractual Receivables and Other Receivables and Lease Inducements, Guardian did not make rent and interest payments under its lease and loan agreements during the first quarter of 2022 but resumed making contractual rent and interest payments during the second quarter of 2022, in accordance with the restructuring terms agreed to in the second quarter of 2022. The mortgage loan is on non-accrual status, and is being accounted for under the cost recovery method, so the $1.4 million of interest payments that we received during the three months ended June 30, 2022 were applied directly against the principal balance outstanding. On February 15, 2022, Guardian completed the sale of three facilities, subject to the Guardian mortgage loan with Omega. Concurrent with the sale, Omega agreed to release the mortgage liens on these facilities in exchange for a partial paydown of $21.7 million. In connection with the partial paydown, we recorded a $5.1 million recovery for credit losses in the first quarter of 2022 related to the Guardian mortgage loan. In the second quarter of 2022, we agreed to a formal restructuring agreement and amendments to the master lease and mortgage loan with Guardian, which among other adjustments, extended the loan maturity and allowed for the deferral of certain contractual interest as discussed in Note 4 – Contractual Receivables and Other Receivables and Lease Inducements. These amendments were treated as a loan modification. Following the mortgage paydown and recoveries, the amortized cost basis of the loan is $80.6 million. The amortized cost basis of the loan represents 10.4% of the total amortized cost basis of all mortgage receivables. As of June 30 2022, the mortgage loan is secured by three SNFs and one ALF located in Pennsylvania. Mortgage Notes due 2030 On June 30, 2022, Ciena Healthcare (“Ciena”) repaid $57.1 million under the $415.0 million amortizing mortgage (the “Master Mortgage”), $15.1 million under the $44.7 million mortgage and $41.5 million under four other additional mortgages. Concurrent with these repayments, we released the mortgage liens on six facilities in exchange for the partial repayment and extended the maturity date of all of the Ciena mortgage notes to June 30, 2030 (with exception of two loans with an aggregate principal balance of $34.3 million with maturity dates in 2022 and 2023).

OTHER INVESTMENTS [Abstract]
OTHER INVESTMENTS	NOTE 6 – OTHER INVESTMENTS Our other investments consist of fixed and variable rate loans to our operators and/or their principals. These loans may be either unsecured or secured by the collateral of the borrower. A number of the secured loans are collateralized by a leasehold mortgage on, or an assignment or pledge of the membership interest in, the related properties, corporate guarantees and/or personal guarantees. We deem these to be “real estate related loans” that are included as qualifying assets under our quarterly REIT asset tests. As of June 30, 2022, we had 39 loans with 19 different operators.

(3) Other investment notes that are real estate related loans have a weighted average interest rate of 11.43% as of June 30, 2022 with maturity dates ranging from 2022 through 2027 (with $10.0 million maturing in 2022 ). (4) Other investment notes that are non-real estate related loans have a weighted average interest rate of 7.77% as of June 30, 2022 with maturity dates ranging from 2022 through 2032 (with $55.3 million maturing in 2022 ). Interest revenue on other investment loans is included within other investment income on the Consolidated Statement of Operations. A summary of our other investments income by real estate and non-real estate loans, as defined above, is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ 2022 2021 ​ 2022 2021 ​ (in thousands) ​ (in thousands) Real estate related loans – interest income $ 9,042 $ 7,869 ​ $ 17,421 $ 15,592 Non-real estate related loans – interest income 2,735 ​ 3,944 ​ 4,950 ​ 7,873 Total other investment income $ 11,777 ​ $ 11,813 ​ $ 22,371 ​ $ 23,465 ​ Other investment note due 2030 On June 22, 2022, we amended the secured revolving credit facility with Maplewood Senior Living (together with its affiliates, “Maplewood”) to increase the maximum commitment under the facility from $220.5 million to $250.5 million. Advances made under this facility bear interest at a fixed rate of 7% per annum, and the facility matures on June 30, 2030. As of June 30, 2022, $225.7 million remains outstanding on this credit facility to Maplewood. Maplewood was determined to be a VIE when this loan was originated in 2020. Please see further discussion in Note 8 – Variable Interest Entities. Other investment notes due 2024-2025 As discussed in Note 4 – Contractual Receivables and Other Receivables and Lease Inducements, Agemo continued to not pay contractual rent and interest to us during the first and second quarters of 2022. We have continued to monitor the fair value of the collateral associated with Agemo’s $25.0 million secured working capital loan (the “Agemo WC Loan”) on a quarterly basis. In the first and second quarters of 2022, we recorded an additional provision for credit losses of $4.7 million and $1.3 million, respectively, related to the Agemo WC Loan as a result of a reduction in the fair value of the underlying collateral assets supporting the current carrying values. The reduction in fair value of the collateral assets in the first and second quarter was driven by a reduction in Agemo’s working capital accessible to Omega as collateral, after considering other liens on the assets. Other investment notes due 2022-2025 Other investment notes due 2022-2028 In connection with the $35.6 million mezzanine loan discussed above, we also entered into a short-term $90.0 million revolving line of credit with the same operator to finance working capital requirements. The line of credit consists of two Other investment notes outstanding – real estate related loans Preferred Equity Investment in Joint Venture - $20 million On June 2, 2022, we made a $20.0 million preferred equity investment, which is treated as a loan for accounting purposes, in a new real estate joint venture that was formed to acquire an acute care hospital in New York. Omega’s preferred equity investment bears a 12% return per annum and must be mandatorily redeemed by the joint venture at the earlier of December 2027 or the occurrence of certain significant events within the joint venture. We have determined that the joint venture is a VIE, but we are not the primary beneficiary as we do not have the power to direct the activities that most significantly impact the joint venture’s economic performance.

Variable Interest Entities [Abstract]
VARIABLE INTEREST ENTITIES	NOTE 8 – VARIABLE INTEREST ENTITIES Unconsolidated Variable Interest Entities We hold variable interests in several VIEs through our investing and financing activities, which are not consolidated, as we have concluded that we are not the primary beneficiary of these entities as we do not have the power to direct activities that most significantly impact the VIE’s economic performance and/or the variable interest we hold does not obligate us to absorb losses or provide us with the right to receive benefits from the VIE which could potentially be significant. Below is a summary of our assets, liabilities and collateral associated with these unconsolidated VIEs as of June 30, 2022 and December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ ​ 2022 ​ 2021 ​ ​ ​ (in thousands) ​ Assets ​ ​ ​ ​ ​ ​ ​ Real estate assets – net ​ $ 1,129,119 ​ $ 1,144,851 ​ Assets held for sale ​ ​ — ​ ​ 191,016 ​ Other investments – net ​ 260,232 ​ ​ 230,768 ​ Contractual receivables – net ​ 1,419 ​ ​ 1,227 ​ Straight-line rent receivables ​ (34,265) ​ ​ (41,512) ​ Lease inducement ​ ​ 61,628 ​ ​ 64,307 ​ Other assets ​ ​ — ​ ​ — ​ Total assets ​ 1,418,133 ​ 1,590,657 ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ ​ Net in-place lease liability ​ ​ (292) ​ ​ (305) ​ Security deposit ​ ​ (4,807) ​ ​ (4,715) ​ Contingent liability ​ ​ (43,915) ​ ​ (43,915) ​ Other liabilities ​ ​ — ​ ​ — ​ Total liabilities ​ (49,014) ​ (48,935) ​ ​ ​ ​ ​ ​ ​ ​ ​ Collateral ​ ​ ​ Letters of credit ​ — ​ ​ — ​ Personal guarantee ​ (48,000) ​ ​ (48,000) ​ Other collateral (1) ​ (1,129,119) ​ ​ (1,335,867) ​ Total collateral ​ (1,177,119) ​ ​ (1,383,867) ​ ​ ​ ​ ​ ​ ​ ​ ​ Maximum exposure to loss ​ $ 192,000 ​ $ 157,855 ​ (1) Amount excludes accounts receivable that Omega has a security interest in as collateral under the two working capital loans with operators that are unconsolidated VIEs. The fair value of the accounts receivable available to Omega was $14.5 million and $29.2 million as of June 30, 2022 and December 31, 2021, respectively. In determining our maximum exposure to loss from the unconsolidated VIEs, we considered the underlying carrying value of the real estate subject to leases with the operator and other collateral, if any, supporting our other investments, which may include accounts receivable, security deposits, letters of credit or personal guarantees, if any, as well as other liabilities recognized with respect to these operators. The table below reflects our total revenues from the operators that are considered unconsolidated VIEs for the three and six months ended June 30, 2022 and 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ ​ 2022 ​ 2021 ​ 2022 ​ 2021 Revenue ​ ​ ​ ​ ​ Rental income ​ $ 21,239 ​ $ 31,375 ​ $ 42,102 ​ $ 61,899 Other investment income ​ 4,335 ​ 4,230 ​ 8,101 ​ 8,175 Total ​ $ 25,574 ​ $ 35,605 ​ $ 50,203 ​ $ 70,074 ​ Consolidated VIEs During the first quarter of 2022, we entered into a joint venture, which owns two ALFs, for a $3.2 million cash contribution, representing 52.4% of the outstanding equity of the joint venture.

Taxes [Abstract]
TAXES	NOTE 13 – TAXES Omega was organized, has operated and intends to continue to operate in a manner that enables Omega to qualify for taxation as a REIT under Sections 856 through 860 of the Code. On a quarterly and annual basis, we perform several analyses to test our compliance within the REIT taxation rules. If we fail to meet the requirements for qualification as a REIT in any tax year, we will be subject to federal income tax on our taxable income at regular corporate rates and may not be able to qualify as a REIT for the four We are also subject to federal taxation of 100% of the net income derived from the sale or other disposition of property, other than foreclosure property, that we held primarily for sale to customers in the ordinary course of a trade or business. We believe that we do not hold assets for sale to customers in the ordinary course of business and that none of the assets currently held for sale or that have been sold would be considered a prohibited transaction within the REIT taxation rules. As a REIT under the Code, we generally will not be subject to federal income taxes on the REIT taxable income that we distribute to stockholders, subject to certain exceptions. In 2021, we distributed dividends in excess of our taxable income. We currently own stock in certain subsidiary REITs. These subsidiaries are required to individually satisfy all of the rules for qualification as a REIT. If we fail to meet the requirements for qualification as a REIT for any of these subsidiaries, it may cause Omega to fail the requirements for qualification as a REIT also. We have elected to treat certain of our active subsidiaries as taxable REIT subsidiaries (“TRSs”). Our domestic TRSs are subject to federal, state and local income taxes at the applicable corporate rates. Our foreign TRSs are subject to foreign income taxes and may cause us to be subject to current-year income inclusion relating to ownership of a controlled foreign corporation for U.S. income tax purposes. As of June 30, 2022, one of our domestic TRSs that is subject to income taxes at the applicable corporate rates had a net operating loss (“NOL”) carry-forward of approximately $10.2 million. Our domestic NOL carry-forward was fully reserved as of June 30, 2022, with a valuation allowance due to uncertainties regarding realization. Under current law, NOL carry-forwards generated up through December 31, 2017, may be carried forward for no more than 20 years, and NOL carry-forwards generated in taxable years ended after December 31, 2017, may be carried forward indefinitely. We do not anticipate that such changes will materially impact the computation of Omega’s taxable income, or the taxable income of any Omega entity, including our TRSs. As discussed in Note 2 – Real Estate Assets, in connection with the acquisition of one U.K. entity in the first quarter of 2022, we acquired foreign net operating losses of $55.0 million resulting in a NOL deferred tax asset of $13.4 million. The NOLs have no expiration date and may be available to offset future taxable income. We believe these foreign NOLs are realizable under a “more likely than not” measurement and have not recorded a valuation allowance against the deferred tax asset. The following is a summary of deferred tax assets and liabilities (which are recorded in other assets and accrued expenses and other liabilities, respectively, in our Consolidated Balance Sheets): ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2022 2021 ​ ​ (in thousands) U.S. Federal net operating loss carryforward ​ $ 2,135 ​ $ 2,221 Valuation allowance on deferred tax asset ​ (2,135) ​ (2,221) Foreign net operating loss carryforward ​ ​ 11,768 ​ ​ — Foreign deferred tax liability (1) ​ (6,508) ​ (8,200) Net deferred tax asset (liability) ​ $ 5,260 ​ $ (8,200) (1) The deferred tax liability primarily resulted from inherited basis differences resulting from our acquisition of entities in the U.K. Subsequent adjustments to these accounts result from GAAP to tax differences related to depreciation, indexation and revenue recognition.

DERIVATIVES AND HEDGING [Abstract]
DERIVATIVES AND HEDGING	NOTE 16 – DERIVATIVES AND HEDGING We are exposed to, among other risks, the impact of changes in foreign currency exchange rates as a result of our investments in the U.K. and interest rate risk related to our capital structure. As a matter of policy, we do not use derivatives for trading or speculative purposes. Our risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes foreign currency forward contracts, interest rate swaps and debt issued in foreign currencies to offset a portion of these risks. As of June 30, 2022, we have five forward starting swaps with $400.0 million in notional value designated as cash flow hedges and six foreign currency forward contracts with £250.0 million (including the two new foreign currency forwards discussed below) in notional value designated as net investment hedges. On May 17, 2022, we entered into two new foreign currency forward contracts with notional amounts totaling £76.0 million and a GBP-USD forward rate of 1.3071, which mature on May 21, 2029. The currency forwards hedge a portion of our net investments in U.K. subsidiaries and our U.K. joint venture. On February 10, 2022, two of our interest rate swaps that were entered into in May 2019 with aggregate notional amounts of $50.0 million matured. These interest rate swap contracts were designated as hedges against our exposure to changes in interest payment cash flow fluctuations in the variable interest rates on the OP term loan. The location and the fair value of derivative instruments designated as hedges, at the respective balance sheet dates, were as follows: ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2022 2021 Cash flow hedges: (in thousands) Other assets $ 73,913 ​ $ 32,849 Accrued expenses and other liabilities $ — ​ $ 96 ​ ​ ​ ​ ​ ​ Net investment hedges: ​ ​ ​ ​ ​ Other assets $ 29,262 ​ $ 6,754 ​ The fair value of the interest rate swaps and foreign currency forwards is derived from observable market data such as yield curves and foreign exchange rates and represents a Level 2 measurement on the fair value hierarchy.

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 18 – COMMITMENTS AND CONTINGENCIES Litigation Shareholder Litigation The Company and certain of its officers, C. Taylor Pickett, Robert O. Stephenson, and Daniel J. Booth Certain derivative actions have also been brought against the officers named in the Securities Class Action, and certain current and former directors of the Company, alleging claims relating to the matters at issue in the Securities Class Action. These derivative actions are currently stayed pending certain developments in the Securities Class Action. In 2018, Stourbridge Investments LLC, a purported stockholder of the Company, filed a derivative action purportedly on behalf of the Company in the U.S. District Court for the Southern District of New York, alleging violations of Section 14(a) of the Exchange Act and state-law claims including breach of fiduciary duty. The complaint alleges, among other things, that the named defendants are responsible for the Company’s failure to disclose the financial condition of Orianna Health Systems, the alleged non-disclosures that are also the subject of the Securities Class Action described above. The plaintiff did not make a demand on the Company to bring the action prior to filing it, but rather alleges that demand would have been futile. The case has been stayed pending the entry of judgment or a voluntary dismissal with prejudice in the Securities Class Action. In 2019, purported stockholder Phillip Swan by his counsel, and stockholders Tom Bradley and Sarah Smith by their counsel, filed derivative actions in the Baltimore City Circuit Court of Maryland, purportedly on behalf of the Company, asserting claims for breach of fiduciary duty, waste of corporate assets and unjust enrichment against the named defendants. Those actions have been consolidated and stayed in the Maryland court pending completion of fact discovery in the Securities Class Action. Prior to filing suit, each of these stockholders had made demands on the Board of Directors in 2018 that the Company bring such lawsuits. After an investigation and due consideration, and in the exercise of its business judgment, the Board of Directors determined that it is not in the best interests of the Company to commence litigation against any current or former officers or directors based on the matters raised in the demands. In addition, in late 2020, Robert Wojcik, a purported shareholder of the Company, filed a derivative action in the U.S. District Court for the District of Maryland, purportedly on behalf of the Company, asserting violations of Section 14(a) of the Exchange Act, Sections 10(b) and 21D of the Exchange Act, as well as claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. Wojcik also did not make a demand on the Company prior to filing suit. The case has been stayed pending the entry of judgment or a voluntary dismissal with prejudice in the Securities Class Action. Other Gulf Coast Subordinated Debt In August 2021, we filed suit in the Circuit Court for Baltimore County (the “Court”) against the holders of certain Subordinated Debt associated with our Gulf Coast master lease agreement, following an assertion by the holders that our prior exercise of offset rights in connection with Gulf Coast’s non-payment of rent had resulted in defaults under the terms of the Subordinated Debt. The suit seeks a declaratory judgment to, among other items, declare that the aggregate amount of unpaid rent due from Gulf Coast under the master lease agreement exceeds all amounts which otherwise would be due and owing by a subsidiary of Omega (“Omega Obligor”) under the Subordinated Debt, and that all principal and interest due and owing under the Subordinated Debt may be (and was) offset in full as of December 31, 2021. In October 2021, the defendants in the case filed a motion to dismiss for lack of personal jurisdiction. A hearing was held on such motion on February 25, 2022, but the decision was taken under advisement. While Omega believes Omega Obligor is entitled to the enforcement of the offset rights sought in the action, the outcome of litigation is unpredictable, and Omega cannot predict the outcome of the declaratory judgment action, irrespective of whether it is litigated in the Court or, if the motion to dismiss for lack of personal jurisdiction is granted, in another court. Lakeway Realty, L.L.C. In September 2016, MedEquities received a Civil Investigative Demand (“CID”) from the U.S. Department of Justice (“DOJ”), which indicates that it is conducting an investigation regarding alleged violations of the False Claims Act, Stark Law and Anti-Kickback Statute in connection with claims that may have been submitted to Medicare and other federal payors for services rendered to patients at Lakeway Hospital or by providers with financial relationships with Lakeway Hospital. As a result of the acquisition of MedEquities, the Company owns a 51% interest in an unconsolidated limited liability company that owns Lakeway Hospital, Lakeway Realty, L.L.C. The CID requested certain documents and information related to the acquisition and ownership of Lakeway Hospital through Lakeway Realty, L.L.C. The Company has learned that the DOJ is investigating, among other items, MedEquities’ conduct in connection with its investigation of financial relationships related to Lakeway Hospital, including allegations by the DOJ that these relationships violate and continue to violate the Anti-Kickback Statute and, as a result, related claims submitted to federal payors violated and continue to violate the False Claims Act. The Company is cooperating fully with the DOJ in connection with the CID and has produced all of the information that has been requested to date. On September 29, 2020, the Department of Justice announced it had reached a settlement of a False Claims Act case with Lakeway Regional Medical Center wherein Lakeway Regional Medical Center agreed to pay $1.1 million for inducing certain physicians to refer patients by offering a low risk and high return investment in the form of a joint venture to purchase and then lease back the hospital to Lakeway Regional Medical Center. A MedEquities subsidiary was a party to this transaction but was not included in settlement discussions, and we understand that the settlement did not fully resolve the investigation referenced in the CID. The documents relating to the settlement are not publicly available. While the Company believes that the acquisition, ownership and leasing of Lakeway Hospital through the Lakeway Partnership was and is in compliance with all applicable laws, in the second quarter of 2022, the Company recorded a $3.0 million legal reserve related to this matter which is included within accrued expenses and other liabilities on the Consolidated Balance Sheets with the related expense included in other (expense) income – net on the Consolidated Statements of Operations. Other In addition, we are subject to various other legal proceedings, claims and other actions arising out of the normal course of business. While any legal proceeding or claim has an element of uncertainty, management believes that the outcome of each lawsuit, claim or legal proceeding that is pending or threatened, or all of them combined, will not have a material adverse effect on our consolidated financial position or results of operations. Indemnification Agreements In connection with certain facility transitions, we have agreed to indemnify certain operators in certain events. As of June 30, 2022, our maximum funding commitment under these indemnification agreements was approximately $5.6 million. Claims under these indemnification agreements generally may be made within 18 months to 72 months of the transition date. These indemnification agreements were provided to certain operators in connection with facility transitions and generally would be applicable in the event that the prior operators do not perform under their transition agreements. Commitments We have committed to fund the construction of new leased and mortgaged facilities, capital improvements and other commitments. We expect the funding of these commitments to be completed over the next several years. Our remaining commitments at June 30, 2022, are outlined in the table below (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Construction and capital expenditure mortgage loan commitments $ 14,632 ​ ​ Lessor construction and capital commitments under lease agreements ​ 199,894 ​ ​ Other investment loan commitments (1) ​ 156,956 ​ ​ Total remaining commitments (2) ​ $ 371,482 ​ ​ (1) This amount includes the $90 million short-term revolving line of credit discussed in Note 6 – Other Investments.

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and notes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the interim periods reported herein are not necessarily indicative of results to be expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the financial statements and the footnotes thereto included in our latest Annual Report on Form 10-K Omega’s consolidated financial statements include the accounts of (i) Parent, (ii) all direct and indirect wholly owned subsidiaries of Omega, including Omega OP, (iii) other entities in which Omega or Omega OP has a majority voting interest and control and (iv) variable interest entities (“VIEs”) of which Omega is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation, and Omega’s net earnings are reduced by the portion of net earnings attributable to noncontrolling interests.
Risks and Uncertainties including COVID-19	Risks and Uncertainties including COVID-19 The Company is subject to certain risks and uncertainties affecting the healthcare industry, including those stemming from the novel coronavirus (“COVID-19”) global pandemic described below, which has disproportionately impacted the senior care sector, as well as those stemming from healthcare legislation and changing regulation by federal, state and local governments. Additionally, we are subject to risks and uncertainties as a result of changes affecting operators of nursing home facilities due to the actions of governmental agencies and insurers to limit the rising cost of healthcare services.
Segments	Segments We conduct our operations and report financial results as one business segment. The presentation of financial results as one reportable segment is consistent with the way we operate our business and is consistent with the manner in which our Chief Operating Decision Maker (CODM), our Chief Executive Officer, evaluates performance and makes resource and operating decisions for the business.
Reclassification	Reclassification Certain line items on our Consolidated Balance Sheets and Consolidated Statements of Cash Flows have been reclassified to conform to the current period presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU – 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures On March 31, 2022, the FASB issued ASU 2022-02, which eliminates the recognition and measurement guidance for troubled debt restructurings (“TDRs”) and requires additional disclosures for certain loan modifications. ASU 2022-02 also requires entities to disclose gross write-offs of financing receivables and net investments in leases by year of origination. Omega elected to early adopt ASU 2022-02 on a prospective basis effective January 1, 2022. In the second quarter of 2022, we had one loan modification to a borrower experiencing financial difficulty pursuant to ASU 2022-02, Guardian Healthcare (“Guardian”), that requires additional disclosures. The required disclosures for this loan are included in Note 4 – Contractual Receivables and Other Receivables and Lease Inducements and Note 5 – Mortgage Notes Receivable. We have disclosed our gross write-offs of financing receivables and direct financing leases by year of origination in Note 7 – Allowance for Credit Losses. ASU – 2020-04, Financial Instruments – Reference Rate Reform (Topic 848) On March 12, 2020, the FASB issued ASU 2020-04, which contains optional practical expedients for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting for contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”). The guidance may be elected over time until December 31, 2022, as reference rate reform activities occur. The Company has several derivative instruments (See Note 16 – Derivatives and Hedging), a $1.45 billion senior unsecured multicurrency revolving credit facility, and a $50.0 million senior unsecured term loan facility (See Note 15 – Borrowing Activities and Arrangements) that reference LIBOR. We also have a $25.0 million senior secured debtor-in-possession (“DIP”) facility loan with an operator that references LIBOR (See Note 6 – Other Investments), but it matures in 2022 prior to LIBOR being discontinued. During the first quarter of 2020, we elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. Our credit facilities that reference LIBOR contain customary LIBOR replacement language, including, but not limited to, the use of rates based on the secured overnight financing rate. The Company continues to evaluate: (i) how the transition away from LIBOR will impact the Company, (ii) whether any additional optional expedients provided by the standards will be adopted, and (iii) the impact that adopting ASU 2020-04 will have on our consolidated financial statements.
