	Organization and Description of Business
	Healthcare Trust of America, Inc., a Maryland corporation, and Healthcare Trust of America Holdings, LP, a Delaware limited partnership, were incorporated or formed, as applicable, on April 20, 2006. Healthcare Trust of America, Inc. (“HTA”) operates as a real estate investment trust, or REIT, and is the general partner of Healthcare Trust of America Holdings, LP (“HTALP”) which is the operating partnership. As of September 30, 2013, HTA owned an approximate 98.94% partnership interest and other limited partners, including some of HTA’s directors, executive officers and their affiliates, owned the remaining partnership interest (including long term incentive plan units) in HTALP. As the sole general partner of HTALP, HTA has the full, exclusive and complete responsibility for HTALP’s day-to-day management and control. HTA’s only material asset is its ownership of partnership interests of HTALP. As a result, HTA does not conduct business itself, other than acting as the sole general partner of HTALP, issuing public equity from time to time and guaranteeing certain debt of HTALP. HTALP holds substantially all of the assets of the Company. HTALP conducts the operations of the business of the Company and is structured as a limited partnership with no publicly traded equity.
	HTA is a fully integrated, self-administered and internally managed REIT and conducts substantially all of its operations through HTALP. We are primarily focused on acquiring, owning and operating high-quality medical office buildings that are predominantly located on, or aligned with, campuses of nationally or regionally recognized healthcare systems. HTA is one of the largest public REITs focused on medical office buildings in the United States based on gross leasable area, or GLA, and has strong industry relationships, a stable and diversified tenant mix, and an extensive and active acquisition network. Our primary objective is to maximize stockholder value with disciplined growth through strategic investments and to provide an attractive risk-adjusted return for our stockholders by consistently increasing our cash flow. In pursuing this objective, we (i) target mid-sized acquisitions of high-quality medical office buildings in markets with dominant healthcare systems, attractive demographics and that complement our existing portfolio, (ii) actively manage our balance sheet to maintain flexibility with conservative leverage, and (iii) seek internal growth through proactive asset management, leasing and property management oversight. HTA has qualified to be taxed as a REIT for federal income tax purposes and intends to continue to be taxed as a REIT.
	We invest primarily in high-quality medical office buildings in our target markets, and have acquired high-quality medical office buildings and other facilities that serve the healthcare industry with an aggregate purchase price of $2.8 billion through September 30, 2013. As of September 30, 2013, our portfolio consisted of 260 medical office buildings and 19 other facilities that serve the healthcare industry, as well as real estate notes receivable secured by medical office buildings.
	On June 6, 2012, HTA listed its Class A common stock on the New York Stock Exchange, or the NYSE, or the Listing. In accordance with an amendment to HTA’s charter approved by stockholders on December 20, 2010, all of the common stock was converted into Class A, Class B-1, Class B-2 and Class B-3 common stock. The Class B common stock is identical to the Class A common stock except that the Class B common stock is not currently listed on a national securities exchange. The shares of the Class B-1 and Class B-2 common stock converted into shares of our Class A common stock on December 6, 2012 and June 6, 2013, respectively, and are now listed on the NYSE. On November 4, 2013, HTA’s Board of Directors announced that the Class B-3 common stock will convert to Class A common stock after the market closes on November 7, 2013 and be eligible for trading on the NYSE.
	Our principal executive offices are located at 16435 N. Scottsdale Road, Suite 320, Scottsdale, Arizona, 85254.

Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	The summary of significant accounting policies presented below is designed to assist in understanding our condensed consolidated financial statements. Such condensed consolidated financial statements and the accompanying notes are the representations of our management, who are responsible for their integrity and objectivity. These accounting policies conform to accounting principles generally accepted in the United States of America, or GAAP, in all material respects, and have been consistently applied in preparing our accompanying condensed consolidated financial statements.
	Reclassifications
	To better present our real estate related balances, we have chosen to break out the details of real estate investments (net) in our balance sheet as opposed to disclosing the details in a footnote. In addition, we have reclassified certain accounts, as further discussed below, in HTA’s previously issued balance sheet to conform to current period presentation. In place leases and tenant relationship intangibles are now included in real estate investments (net) as lease intangibles. In addition, accounts and other receivables (net) have been combined with receivables and other assets (net). None of the revised reclassifications reflect corrections of any amounts. The following table presents the previously reported balances of and the reclassified balances for the impacted line items of the December 31, 2012 balance sheet (in thousands):
		December 31, 2012
		As Previously Reported		As Reclassified
	Real estate investments:
	Land	$	—	$	183,651
	Building and improvements	—		2,044,113
	Lease intangibles	—		352,884

	Accumulated depreciation and amortization	—		(349,118		)
	Real estate investments, net	1,992,607		2,231,530
	Accounts and other receivables, net	13,317		—
	Receivables and other assets, net	71,653		84,970
	Other intangibles, net	282,934		44,011
	Real Estate Depreciation
	Depreciation expense of buildings and improvements for the three months ended September 30, 2013 and 2012, was $18.9 million and $17.8 million, respectively. Depreciation expense of buildings and improvements for the nine months ended September 30, 2013 and 2012, was $55.5 million and $53.0 million, respectively.
	Listing Expenses
	Listing expenses primarily include fees associated with the Listing and share-based compensation expense associated with the long term incentive program, or LTIP, awards that we granted in connection with the Listing.
	Noncontrolling Interests
	HTA’s net income attributable to noncontrolling interests in its accompanying condensed consolidated statements of operations relate to both noncontrolling interest reflected within equity and redeemable noncontrolling interest of limited partners reflected outside of equity in our accompanying condensed consolidated balance sheets. Limited partner units in HTALP are accounted for as partners’ capital in HTALP’s condensed consolidated balance sheets and as noncontrolling interest reflected within equity or redeemable noncontrolling interest of limited partners reflected outside of equity in HTA’s condensed consolidated balance sheets.
	Interim Unaudited Financial Data
	Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the Securities and Exchange Commission, or the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments, which are, in our opinion, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim period. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such results may be less favorable for the full year. Our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in the 2012 Annual Report on Form 10-K for HTA and the Registration Statement on Form S-4 for HTALP, as amended, that was declared effective by the SEC on October 22, 2013 (File No. 333-190916).
	Recently Issued or Adopted Accounting Pronouncements
	In January 2013, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, 2013-01, Balance Sheet (Topic 210) - Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, or ASU 2013-01, which clarifies the scope of ASU 2011-11, Balance Sheet (Topic 210) - Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 requires entities to disclose both gross and net information about derivatives, including bifurcated embedded derivatives, repurchase agreements and reverse purchase agreements and securities borrowing and securities lending transactions that are subject to an agreement similar to a master netting arrangement. Entities are required to apply these disclosures for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity must provide the disclosures required by those amendments retrospectively for all comparative periods presented. We adopted ASU 2011-11 and ASU 2013-01 in the first quarter of fiscal 2013 and have reflected the adoption in our disclosures to our interim condensed consolidated financial statements.

	Business Combinations
	For the nine months ended September 30, 2013, we have completed seven acquisitions for an aggregate purchase price of $241.9 million, in addition to closing costs attributable to these acquisitions of $1.4 million. Results of operations for these acquisitions are reflected in our condensed consolidated statements of operations for the three and nine months ended September 30, 2013, for the periods subsequent to the acquisition dates.
	The aggregate net purchase price of the 2013 acquisitions was allocated in the amounts set forth in the table below. Due to the recent timing of certain acquisitions, we have not yet finalized our purchase price allocation. Since the acquisitions were determined to be individually not significant, but material on a collective basis, the allocations for these acquisitions are set forth below in the aggregate (in thousands):
	2013 Acquisitions		Total

	Aggregate purchase price		$	241,914
	The weighted average lives of the above acquired intangible assets and liabilities were 7.4 years and 5.7 years, respectively.
	The property acquisitions completed during the nine months ended September 30, 2013, were all cash transactions except for the acquisition on September 20, 2013 and we acquired a 100% ownership interest in each property acquisition. See below for a brief description of each of the acquisitions.

	•	On September 20, 2013, we completed the acquisition of a portfolio of medical office buildings located in South Florida for $62.9 million. As part of the acquisition, we assumed approximately $18.0 million of mortgage loans.
	In addition, we have entered into two definitive purchase agreements for the acquisition of medical office buildings located in Austin, Texas totaling approximately $30.0 million. The closing of these acquisitions are subject to the satisfaction of customary closing conditions.
	The aggregate net purchase price of the 2012 acquisitions was allocated in the amounts set forth in the table below. Since the acquisitions were determined to be individually not significant, but material on a collective basis, the allocations for these acquisitions are set forth below in the aggregate (in thousands):

	Real Estate Notes Receivable
	Real estate notes receivable includes four promissory notes totaling $20.0 million as of September 30, 2013 and December 31, 2012. The promissory notes are secured by medical office buildings, with interest rates ranging from 10.85% to 10.95% per annum. The weighted average effective interest rate based on the purchase price of the notes was 14.57% per annum as of September 30, 2013. The promissory notes matured on November 1, 2013 and we expect to receive payment on the principal balance or extend the maturity date during the quarter ending December 31, 2013. The promissory notes have sufficient collateral coverage based on the value of the medical office buildings. The promissory notes will continue to accrue interest as the same per annum rates and as of September 30, 2013 all interest payments were current.
	In addition, we originated two promissory notes in September 2013 totaling $8.5 million. The promissory notes are secured by medical office buildings in South Florida, each with an interest rate of 7.0% per annum. The properties are being actively marketed for sale and the notes will be repaid upon any sale. The promissory notes mature on October 1, 2016.
	We monitor the credit quality of our real estate notes receivable on an ongoing basis by tracking possible credit quality indicators. As of September 30, 2013, all of our real estate notes receivable are current and we have not provided for any allowance for losses or recorded any impairments with respect to our notes receivable. We made no purchases or sales of real estate notes receivable during the nine months ended September 30, 2013.

	Unsecured Credit Agreement
	On March 29, 2012, we entered into an unsecured credit agreement to obtain a $575.0 million unsecured revolving credit facility and a $300.0 million unsecured term loan. On March 7, 2013, we executed an amendment to the unsecured credit agreement pursuant to an existing provision therein to increase the principal amount of the unsecured revolving credit facility. This amendment added an additional lender and increased the unsecured revolving credit facility by $75.0 million to $650.0 million. The other existing terms of the unsecured credit agreement were unchanged. The unsecured credit agreement matures on March 29, 2016 and includes a one-year extension option, subject to certain conditions.
	The actual amount of credit available under our unsecured credit agreement is a function of certain loan-to-value and debt service coverage ratios. The maximum principal amount may be increased; subject to such additional financing being provided by our existing lenders or new lenders added to the unsecured revolving credit facility.
	Borrowings under the $650.0 million unsecured revolving credit facility accrue interest equal to adjusted LIBOR plus a margin ranging from 1.10% to 1.75% per annum based on our credit rating. We also pay a facility fee ranging from 0.20% to 0.50% per annum on the aggregate commitments under the unsecured revolving credit facility. As of September 30, 2013, the margin associated with borrowings was 1.55% per annum and the facility fee was 0.35% per annum. As of September 30, 2013, no amount was outstanding on our unsecured revolving credit facility.
	Borrowings under the $300.0 million unsecured term loan accrue interest equal to adjusted LIBOR plus a margin ranging from 1.30% to 2.25% per annum based on our credit rating. The margin associated with borrowings as of September 30, 2013 was 1.85% per annum. We have interest rate swaps in place that fix the interest rate at 2.95% per annum, based on our current credit rating.
	$155.0 million Unsecured Term Loan
	On July 20, 2012, we entered into a $155.0 million unsecured term loan that matures on July 19, 2019. The interest rate thereon is equal to LIBOR plus a margin ranging from 1.55% to 2.40% per annum based on our credit rating. The margin associated with the borrowings as of September 30, 2013 was 2.00% per annum. We have interest rate swaps in place that fix the interest rate at 3.29% per annum, based on our current credit rating. The maximum principal amount may be increased by us, subject to such additional financing being provided by our existing lender.

	On March 28, 2013, we issued $300.0 million of unsecured senior notes that mature on April 15, 2023. The unsecured senior notes bear interest at 3.70% per annum payable semi-annually and were offered at 99.186% of the principal amount thereof. The unsecured senior notes include registration rights to the holders, pursuant to which we filed an exchange offer on Form S-4 on October 22, 2013.
	Fixed Rate Mortgages
	As of September 30, 2013, we had fixed rate mortgages with interest rates ranging from 4.55% to 12.75% per annum and a weighted average interest rate of 5.86% per annum. As part of an acquisition, we assumed two mortgage loans; see Note 3, Business Combinations.
	Secured Real Estate Term Loan
	On March 28, 2013, we repaid in full the $125.5 million secured real estate term loan. In connection with that repayment, we terminated the secured real estate term loan (and the commitments thereunder) and the related security documents and guarantees. In addition, we terminated the $75.0 million interest rate swap associated with the secured real estate term loan.
	Future Debt Maturities
	As of September 30, 2013, the principal payments due on our debt for the three months ending December 31, 2013, for each of the next four years ending December 31 and thereafter, is as follows (in thousands):
	Year	Amount
	2013	$	1,722
	2014	6,872
	2015	73,128
	2016	421,578
	2017	99,963
	Thereafter	522,373
	Total	$	1,125,636
	The above scheduled debt maturities do not include the available extension under the unsecured credit agreement as discussed above.
	We are required by the terms of our applicable credit agreements to meet various affirmative and negative covenants that we believe are customary for these types of facilities, such as limitations on the incurrence of debt by us, and our subsidiaries that own unencumbered assets, limitations on the nature of HTALP’s business, and limitations on distributions by HTALP and its subsidiaries that own unencumbered assets. Our credit agreements also impose various financial covenants on us, such as a maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a minimum tangible net worth covenant, a maximum ratio of unsecured indebtedness to unencumbered asset value, rent coverage ratios, and a minimum ratio of unencumbered net operating income to unsecured interest expense. As of September 30, 2013, we believe that we were in compliance with all such financial covenants and reporting requirements. In addition, certain of our credit agreements include events of default provisions that we believe are customary for these types of facilities, including restricting HTA from making dividend distributions to our stockholders in the event we are in default, except to the extent necessary for HTA to maintain its REIT status.

	We have agreements with each of our interest rate swap derivative counterparties that contain a provision whereby if we default on certain of our unsecured indebtedness, then our counterparties could declare us in default on our interest rate swap derivative obligations resulting in an acceleration of the indebtedness. In addition, we are exposed to credit risk in the event of non-performance by our derivative counterparties. We believe we mitigate the credit risk by entering into agreements with credit-worthy counterparties. We record counterparty credit risk valuation adjustments on interest rate swap derivative assets in order to properly reflect the credit quality of the counterparty. In addition, our fair value of interest rate swap derivative liabilities is adjusted to reflect the impact of our credit quality.

	Stockholders’ Equity and Partners’ Capital
	HTALP’s partnership agreement provides that it will distribute cash flows from operations and net sale proceeds to its partners in accordance with their overall ownership interests at such times and in such amounts as the general partner determines. Except for certain LTIP units that have not vested, dividend distributions are made such that a holder of one unit will receive annual dividend distributions from HTALP in an amount equal to the annual dividends paid to the holder of one of HTA’s shares. In addition, for each share of common stock issued or redeemed by HTA, HTALP issues or redeems a corresponding number of units.
	Common Stock Offerings
	On January 7, 2013, HTA commenced an equity at-the-market, or ATM, offering of its Class A common stock with an aggregate sales price of up to $250.0 million. During the nine months ended September 30, 2013, HTA issued and sold 20,707,113 shares, at an average price of $11.24 per share. On November 1, 2013, HTA terminated this ATM offering and commenced a new ATM offering of its Class A common stock with an aggregate sales price of up to $300.0 million.
	Common Stock Dividends
	The following are the cash dividends declared by HTA on all Class A and B common stock during 2013:

	Incentive Plan
	Our Amended and Restated 2006 Plan, or the Plan, permits the grant of incentive awards to our employees, officers, non-employee directors, and consultants as selected by our Board of Directors or the Compensation Committee. The Plan authorizes the granting of awards in any of the following forms: options; stock appreciation rights; restricted stock; restricted or deferred stock units; performance awards; dividend equivalents; other stock-based awards, including units in HTALP; and cash-based awards. The service period is generally three or four years. Subject to adjustment as provided in the Plan, the aggregate number of awards reserved and available for issuance under the Plan is 10,000,000. As of September 30, 2013, there were 5,096,100 awards available for grant under the Plan.
	Long Term Incentive Program of OP Units
	Awards under the LTIP consist of Series C units in HTALP, and are subject to the achievement of certain performance and market conditions in order to vest. Once vested, the Series C units are converted into common units of HTALP, which may be converted into shares of HTA’s common stock.
	For the three and nine months ended September 30, 2013, we recognized compensation expense related to LTIP awards of $0.0 million and $3.1 million, respectively, which was recorded in listing expenses. For the three and nine months ended September 30, 2012, we recognized compensation expense related to LTIP awards of $4.5 million and $5.9 million, respectively, which was recorded in listing expenses. As of September 30, 2013, there was approximately $4.5 million of unrecognized expense associated with 450,000 units that will only vest as a result of a change in control. We will not recognize any expense associated with these units until such event occurs or is probable.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Financial Instruments Reported at Fair Value
	Derivative Financial Instruments
	Currently, we use interest rate swaps to manage interest rate risk associated with variable rate debt. The valuation of these instruments is determined with the assistance of an independent valuation specialist using a proprietary model that utilizes widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative, and observable inputs. As such, we classify these inputs as Level 2. The proprietary model reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.
	We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.
	Although we have determined that the majority of the inputs used to value our interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with these instruments utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our interest rate swap derivative positions and have determined that the credit valuation adjustments are not significant to their overall valuation. As a result, we have determined that our interest rate swap derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

	Financial Instruments Disclosed at Fair Value
	We consider the carrying values of cash and cash equivalents, accounts and other receivables (net), restricted cash and escrow deposits, and accounts payable and accrued liabilities to approximate fair value for these financial instruments because of the short period of time between origination of the instruments and their expected realization. All of these financial instruments are considered Level 2.

In addition, we have reclassified certain accounts, as further discussed below, in HTA’s previously issued balance sheet to conform to current period presentation. In place leases and tenant relationship intangibles are now included in real estate investments (net) as lease intangibles. In addition, accounts and other receivables (net) have been combined with receivables and other assets (net). None of the revised reclassifications reflect corrections of any amounts.

ASU 2013-01 requires entities to disclose both gross and net information about derivatives, including bifurcated embedded derivatives, repurchase agreements and reverse purchase agreements and securities borrowing and securities lending transactions that are subject to an agreement similar to a master netting arrangement. Entities are required to apply these disclosures for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity must provide the disclosures required by those amendments retrospectively for all comparative periods presented. We adopted ASU 2011-11 and ASU 2013-01 in the first quarter of fiscal 2013 and have reflected the adoption in our disclosures to our interim condensed consolidated financial statements.
