The Company and Basis of Presentation	1. The Company and Basis of Presentation
	The Company
	Fresenius Medical Care AG & Co. KGaA (“FMC-AG & Co. KGaA” or the “Company”), a German partnership limited by shares (Kommanditgesellschaft auf Aktien), is the world's largest kidney dialysis company. The Company provides dialysis care services related to the dialysis treatment a patient with end-stage renal disease (“ESRD”) receives, as well as other health care services. We describe our other health care services as “Care Coordination.” Care Coordination services include the coordinated delivery of pharmacy services, vascular, cardiovascular and endovascular specialty services, non-dialysis laboratory testing services, physician services, hospitalist and intensivist services, health plan services and urgent care services, which, together with dialysis care services represent the Company's health care services. In addition, the Company also provides dialysis products for the treatment of ESRD, including products manufactured and distributed by the Company such as hemodialysis machines, peritoneal cyclers, dialyzers, peritoneal solutions, hemodialysis concentrates, solutions and granulates, bloodlines, renal pharmaceuticals and systems for water treatment. The Company supplies dialysis clinics it owns, operates or manages with a broad range of products in addition to sales of dialysis products to other dialysis service providers.
	In these unaudited consolidated financial statements, “FMC-AG & Co. KGaA,” or the “Company,” “we,” “us” or “our” refers to the Company or the Company and its subsidiaries on a consolidated basis, as the context requires. The term “North America Segment” refers to the North America operating segment; the term “EMEA Segment” refers to the Europe, Middle East and Africa operating segment, the term “Asia-Pacific Segment” refers to the Asia-Pacific operating segment, and the term “Latin America Segment” refers to the Latin America operating segment. For further discussion of the Company's operating segments, see Note 15 “Segment and Corporate Information.”
	Basis of Presentation
	The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
	The consolidated financial statements at March 31, 2015 and for the three months ended March 31, 2015 and 2014 contained in this report are unaudited and should be read in conjunction with the consolidated financial statements contained in the Company's 2014 Annual Report on Form 20-F. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Such financial statements reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of the results of the periods presented. All such adjustments are of a normal recurring nature.
	The accounting policies applied in the accompanying consolidated financial statements are the same as those applied in the consolidated financial statements at and for the year ended December 31, 2014, contained in the Company's 2014 Annual Report on Form 20-F.
	The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results of operations for the year ending December 31, 2015.

Related Party Transactions	2. Related Party Transactions
	The Company's parent, Fresenius SE & Co. KGaA (“Fresenius SE”), a German partnership limited by shares, owns 100% of the share capital of Fresenius Medical Care Management AG, the Company's general partner (“General Partner”). Fresenius SE is also the Company's largest shareholder and owns approximately 31.1% of the Company's outstanding shares at March 31, 2015. The Company has entered into certain arrangements for services, leases and products with Fresenius SE or its subsidiaries and with certain of the Company's equity method investees as described in item a) below. The Company's terms related to the receivables or payables for these services, leases and products are generally consistent with the normal terms of the Company's ordinary course of business transactions with unrelated parties. Financing arrangements as described in item b) below have agreed upon terms which are determined at the time such financing transactions occur and reflect market rates at the time of the transaction. The relationship between the Company and its key management personnel who are considered to be related parties is described in item c) below. Our related party transactions are settled through Fresenius SE's cash management system where appropriate.
	a)       Service Agreements, Lease Agreements and Products
	The Company is party to service agreements with Fresenius SE and certain of its affiliates (collectively the “Fresenius SE Companies”) to receive services, including, but not limited to: administrative services, management information services, employee benefit administration, insurance, information technology services, tax services and treasury management services. The Company also provides certain services to the Fresenius SE Companies, including research and development, central purchasing and warehousing. Under these agreements, the Company also performs clinical studies and marketing and distribution services for certain of its equity method investees.
	The Company is party to real estate operating lease agreements with the Fresenius SE Companies, which include leases for the Company's corporate headquarters in Bad Homburg, Germany and production sites in Schweinfurt and St. Wendel, Germany. The majority of the leases expire in 2016 and contain renewal options.
	In addition to the above mentioned service and lease agreements, the Company sold products to the Fresenius SE Companies and made purchases from the Fresenius SE Companies. In addition, Fresenius Medical Care Holdings, Inc. (“FMCH”) purchases heparin supplied by Fresenius Kabi USA, Inc. (“Kabi USA”), through an independent group purchasing organization (“GPO”). Kabi USA is wholly-owned by Fresenius Kabi AG, a wholly-owned subsidiary of Fresenius SE. The Company has no direct supply agreement with Kabi USA and does not submit purchase orders directly to Kabi USA. FMCH acquires heparin from Kabi USA, through the GPO contract, which was negotiated by the GPO at arm's length on behalf of all members of the GPO.
	The Company entered into an agreement with a Fresenius SE company for the manufacturing of plasma collection devices. The Company agreed to produce 3,500 units which can be further increased to a maximum of 4,550 units, over the length of the five year contract. On January 1, 2015, this manufacturing business was sold to Kabi USA in the amount of $9,327 for which a fairness opinion was obtained from a reputable global accounting firm. The disposal was accounted for as a transaction between parties under common control at the carrying amounts without the generation of profits.
	Below is a summary, including the Company's receivables from and payables to the indicated parties resulting from the above described transactions with related parties.

	b)       Financing

The Senior Notes were issued in 2014, mature in 2020 and 2024, respectively, and have a coupon rate of 4.125% and 4.75%. As of January 7, 2015, Fresenius SE sold all positions held on these Senior Notes.
	At March 31, 2015 and December 31, 2014, a subsidiary of Fresenius SE held unsecured Senior Notes issued by the Company in the amount of €8,300 and €8,300 ($8,930 at March 31, 2015 and $10,077 at December 31, 2014), respectively.

	c)       Key Management Personnel
	Due to the legal form of a German partnership limited by shares, the General Partner holds a key management position within the Company.

	On August 12, 2013, FMCH made an investment-type transaction by providing a credit facility to a middle-market dialysis provider in the amount of up to $200,000 to fund general corporate purposes. The transaction is in the form of subordinated notes with a maturity date of July 4, 2020 (unless prepaid) and a payment-in-kind (“PIK”) feature that will allow interest payments in the form of cash (at 10.75%) or PIK (at 11.75%). The PIK feature, if used, allows for the addition of the accrued interest to the then outstanding principal. The collateral for this loan is 100% of the equity interest in this middle-market dialysis provider. The availability period for drawdowns on this loan was 18 months and ended on February 12, 2015. The Company assesses the recoverability of this investment based on quarterly financial statements and other information obtained, used for an assessment of profitability and business plan objectives, as well as by analyzing general economic and market conditions in which the provider operates. On April 30, 2014, the Payee exercised the PIK feature and converted $10,137 of accrued interest then due to outstanding principal. Consequently, at March 31, 2015, $180,137 is effectively drawn down with $8,260 of interest income accrued. Interest is payable on a semi-annual basis.

Noncontrolling Interests Subject to Put Provisions	10. Noncontrolling Interests Subject to Put Provisions
	The Company has potential obligations to purchase the noncontrolling interests held by third parties in certain of its consolidated subsidiaries. These obligations are in the form of put provisions and are exercisable at the third-party owners' discretion within specified periods as outlined in each specific put provision. If these put provisions were exercised, the Company would be required to purchase all or part of third-party owners' noncontrolling interests at the appraised fair value at the time of exercise. The methodology the Company uses to estimate the fair values of the noncontrolling interest subject to put provisions assumes the greater of net book value or a multiple of earnings, based on historical earnings, development stage of the underlying business and other factors. The estimated fair values of the noncontrolling interests subject to these put provisions can also fluctuate and the implicit multiple of earnings at which these noncontrolling interest obligations may ultimately be settled could vary significantly from our current estimates depending upon market conditions.
	At March 31, 2015 and December 31, 2014, the Company's potential obligations under these put options were $827,094 and $824,658. At March 31, 2015 and December 31, 2014, put options with an aggregate purchase obligation of $130,927 and $123,846, respectively, were exercisable. No put options were exercised during the first three months of 2015.
	The following is a roll forward of noncontrolling interests subject to put provisions for the three months ended March 31, 2015 and the year ended December 31, 2014:
		31-Mar-15		31-Dec-14

	(1) Also includes amounts from related parties.
	(2) Includes long-term accounts receivable, which are included in "Other assets and notes receivables" in the Consolidated Balance Sheets.
	The carrying amounts in the table are included in the Consolidated Balance Sheets under the indicated captions or in the case of long-term debt, in the captions shown in Note 6.
	The significant methods and assumptions used in estimating the fair values of non-derivative financial instruments are as follows:
	Cash and cash equivalents are stated at nominal value which equals the fair value.
	Short-term financial instruments such as accounts receivable, accounts payable and short-term borrowings are valued at their carrying amounts, which are reasonable estimates of the fair value due to the relatively short period to maturity of these instruments.
	The fair value of available for sale financial assets quoted in an active market is based on price quotations at the period-end date.
	The valuation of notes receivable was determined using significant unobservable inputs. They were valued using a constructed index based upon similar instruments with comparable credit ratings, terms, tenor, interest rates and that are within the Company's industry. The Company tracked the prices of the constructed index from the note issuance date to the reporting date to determine fair value. See Note 4 for further information on the long-term notes receivable.
	The fair values of major long-term financial liabilities are calculated on the basis of market information. Instruments for which market quotes are available are measured using these quotes. The fair values of the other long-term financial liabilities are calculated at the present value of the respective future cash flows. To determine these present values, the prevailing interest rates and credit spreads for the Company as of the balance sheet date are used.
	The valuation of noncontrolling interests subject to put provisions is determined using significant unobservable inputs. See Note 10 for a discussion of the Company's methodology for estimating the fair value of these noncontrolling interests subject to put obligations.
	Currently, there is no indication that a decrease in the value of the Company's financing receivables is probable. Therefore, the allowances on credit losses of financing receivables are immaterial.
	Derivative Financial Instruments
	The Company is exposed to market risk from changes in foreign exchange rates and interest rates. In order to manage the risk of currency exchange rate and interest rate fluctuations, the Company enters into various hedging transactions by means of derivative instruments with highly rated financial institutions as authorized by the Company's General Partner. On a quarterly basis the Company performs an assessment of its counterparty credit risk. The Company currently considers this risk to be low. The Company's policy, which has been consistently followed, is that financial derivatives be used only for the purpose of hedging foreign currency and interest rate exposure.
	In certain instances, the Company enters into derivative contracts that do not qualify for hedge accounting but are utilized for economic purposes (“economic hedges”). The Company does not use financial instruments for trading purposes.
	The Company established guidelines for risk assessment procedures and controls for the use of financial instruments. They include a clear segregation of duties with regard to execution on one side and administration, accounting and controlling on the other.
	To reduce the credit risk arising from derivatives the Company concluded Master Netting Agreements with banks. Through such agreements, positive and negative fair values of the derivative contracts could be offset against one another if a partner becomes insolvent. This offsetting is valid for transactions where the aggregate amount of obligations owed to and receivable from are not equal. If insolvency occurs, the party which owes the larger amount is obliged to pay the other party the difference between the amounts owed in the form of one net payment.
	The Company elects not to offset the fair values of derivative financial instruments subject to master netting agreements in its Consolidated Balance Sheets.
	At March 31, 2015 and December 31, 2014, the Company had $26,958 and $26,820 of derivative financial assets subject to netting arrangements and $97,906 and $52,380 of derivative financial liabilities subject to netting arrangements. Offsetting these derivative financial instruments would have resulted in net assets of $6,628 and $13,856 as well as net liabilities of $77,576 and $39,416 at March 31, 2015 and December 31, 2014, respectively.
	In connection with the issuance of the Convertible Bonds, the Company purchased Share Options. Any change in the Company's share price above the conversion price would be offset by a corresponding value change in the Share Options.
	Foreign Exchange Risk Management
	The Company conducts business on a global basis in various currencies, though a majority of its operations are in Germany and the United States. For financial reporting purposes, the Company has chosen the U.S. dollar as its reporting currency. Therefore, changes in the rate of exchange between the U.S. dollar and the local currencies in which the financial statements of the Company's international operations are maintained affect its results of operations and financial position as reported in its consolidated financial statements.
	The Company's exposure to market risk for changes in foreign exchange rates relates to transactions such as sales and purchases. The Company has significant amounts of sales of products invoiced in euro from its European manufacturing facilities to its other international operations and, to a lesser extent, sales of products invoiced in other non-functional currencies. This exposes the subsidiaries to fluctuations in the rate of exchange between the euro and the currency in which their local operations are conducted. For the purpose of hedging existing and foreseeable foreign exchange transaction exposures the Company enters into foreign exchange forward contracts and, on a small scale, foreign exchange options. At March 31, 2015 and December 31, 2014, the Company had no foreign exchange options.
	Changes in the fair value of the effective portion of foreign exchange forward contracts designated and qualifying as cash flow hedges of forecasted product purchases and sales are reported in Accumulated Other Comprehensive Income (“AOCI”). Additionally, in connection with intercompany loans in foreign currency, the Company uses foreign exchange swaps thus assuring that no foreign exchange risks arise from those loans, which, if they qualify for cash flow hedge accounting, are also reported in AOCI. These amounts recorded in AOCI are subsequently reclassified into earnings as a component of cost of revenues for those contracts that hedge product purchases or as an adjustment of interest income/expense for those contracts that hedge loans, in the same period in which the hedged transaction affects earnings. The notional amounts of foreign exchange contracts in place that are designated and qualify as cash flow hedges totaled $280,574 and $401,555 at March 31, 2015 and December 31, 2014, respectively.
	The Company also enters into derivative contracts for forecasted product purchases and sales and for intercompany loans in foreign currency that do not qualify for hedge accounting but are utilized for economic hedges as defined above. In these two cases, the change in value of the economic hedge is recorded in the income statement and usually offsets the change in value recorded in the income statement for the underlying asset or liability. The notional amounts of economic hedges that do not qualify for hedge accounting totaled $1,345,171 and $1,568,928 at March 31, 2015 and December 31, 2014, respectively.
	Interest Rate Risk Management
	The Company enters into derivatives, particularly interest rate swaps and to a certain extent, interest rate options, to protect against the risk of rising interest rates. These interest rate derivatives are designated as cash flow hedges and have been entered into in order to effectively convert payments based on variable interest rates into payments at a fixed interest rate. The euro-denominated interest rate swaps expire between 2016 and 2019 and have a weighted average interest rate of 0.68%. Interest payable and receivable under the swap agreements is accrued and recorded as an adjustment to interest expense.
	At March 31, 2015 and December 31, 2014, the notional amount of the euro-denominated interest rate swaps in place was €394,000 and €394,000 ($423,905 and $478,355 at March 31, 2015 and December 31, 2014, respectively).
	In addition, the Company also enters into interest rate hedges (“pre-hedges”) in anticipation of future debt issuance, from time to time. These pre-hedges are used to hedge interest rate exposures with regard to interest rates which are relevant for the future debt issuance and which could rise until the respective debt is actually issued. These pre-hedges were settled at the issuance date of the corresponding debt with the settlement amount recorded in AOCI amortized to interest expense over the life of the pre-hedges. At March 31, 2015 and December 31, 2014, the Company had $71,526 and $85,675, respectively, related to such settlements of pre-hedges deferred in AOCI, net of tax.

(1) At March 31, 2015 and December 31, 2014, the valuation of the Company's derivatives was determined using Significant Other Observable Inputs (Level 2) in accordance with the fair value hierarchy levels established in U.S. GAAP.
(2) Derivative instruments are marked to market each reporting period resulting in carrying amounts being equal to fair values at the reporting date.
The carrying amounts for the current portion of derivatives indicated as assets in the table above are included in Prepaid expenses and other current assets in the Consolidated Balance Sheets while the current portion of those indicated as liabilities are included in Accrued expenses and other current liabilities. The non-current portions indicated as assets or liabilities are included in the Consolidated Balance Sheets in Other assets or Other liabilities, respectively.
The significant methods and assumptions used in estimating the fair values of derivative financial instruments are as follows:
The fair value of interest rate swaps is calculated by discounting the future cash flows on the basis of the market interest rates applicable for the remaining term of the contract as of the balance sheet date. To determine the fair value of foreign exchange forward contracts, the contracted forward rate is compared to the current forward rate for the remaining term of the contract as of the balance sheet date. The result is then discounted on the basis of the market interest rates prevailing at the balance sheet date for the applicable currency. The fair value of the embedded derivative of the convertible bonds is calculated using the difference between the market value of the convertible bond and the market value of an adequate straight bond discounted with the market interest rates as of the reporting date.
The Company includes its own credit risk for financial instruments deemed liabilities and counterparty-credit risks for financial instruments deemed assets when measuring the fair value of derivative financial instruments.

For foreign exchange derivatives, the Company expects to recognize $17,873 of losses deferred in AOCI at March 31, 2015, in earnings during the next twelve months.
The Company expects to incur additional interest expense of $20,306 over the next twelve months which is currently deferred in AOCI. This amount reflects the projected amortization of the settlement amount of the terminated swaps and the current fair value of the additional interest payments resulting from the interest rate swaps maturing between 2016 and 2019 at March 31, 2015.
At March 31, 2015, the Company had foreign exchange derivatives with maturities of up to 14 months and interest rate swaps with maturities of up to 55 months.

Business Segment Information	15. Segment and Corporate Information
	In 2015, the Company increased its operating segments from three to four segments to align with the way in which it is currently managed. The operating segments are the North America Segment, the EMEA Segment, the Asia-Pacific Segment and the Latin America Segment. Accordingly, the two reporting segments disclosed in prior years (the North America Segment and the International Segment, which was comprised of EMEA, Asia-Pacific and Latin America) have now been reclassified into four reporting segments during 2015.
	Management evaluates each segment using measures that reflect all of the segment's controllable revenues and expenses. With respect to the performance of business operations, management believes that the most appropriate U.S. GAAP measures are revenue, operating income and operating income margin. The Company does not include income taxes as it believes this is outside the segments' control. Financing is a corporate function, which the Company's segments do not control. Therefore, the Company does not include interest expense relating to financing as a segment measurement. Similarly, the Company does not allocate certain costs, which relate primarily to certain headquarter overhead charges, including accounting and finance, because the Company believes that these costs are also not within the control of the individual segments. Production of products, production asset management, quality management and procurement are centrally managed at Corporate. The Company's global research and development is also centrally managed at Corporate. These Corporate activities do not fulfill the definition of a segment. Products are transferred to the segments at cost; therefore no internal profit is generated. The associated internal revenues for the product transfers and their elimination are recorded as Corporate activities. Capital expenditures for production are based on the expected demand of the segments and consolidated profitability considerations. In addition, certain revenues, investments and intangible assets, as well as any related expenses, are not allocated to a segment but are accounted for as Corporate.
	Information pertaining to the Company's segment and Corporate activities for the three-month periods ended March 31, 2015 and 2014 is set forth below.

Noncontrolling Interests Subject To Put Provisions (Tables) [Abstract]
Noncontrolling Interests Subject to Put Provisions	10. Noncontrolling Interests Subject to Put Provisions
	The Company has potential obligations to purchase the noncontrolling interests held by third parties in certain of its consolidated subsidiaries. These obligations are in the form of put provisions and are exercisable at the third-party owners' discretion within specified periods as outlined in each specific put provision. If these put provisions were exercised, the Company would be required to purchase all or part of third-party owners' noncontrolling interests at the appraised fair value at the time of exercise. The methodology the Company uses to estimate the fair values of the noncontrolling interest subject to put provisions assumes the greater of net book value or a multiple of earnings, based on historical earnings, development stage of the underlying business and other factors. The estimated fair values of the noncontrolling interests subject to these put provisions can also fluctuate and the implicit multiple of earnings at which these noncontrolling interest obligations may ultimately be settled could vary significantly from our current estimates depending upon market conditions.
	At March 31, 2015 and December 31, 2014, the Company's potential obligations under these put options were $827,094 and $824,658. At March 31, 2015 and December 31, 2014, put options with an aggregate purchase obligation of $130,927 and $123,846, respectively, were exercisable. No put options were exercised during the first three months of 2015.
	The following is a roll forward of noncontrolling interests subject to put provisions for the three months ended March 31, 2015 and the year ended December 31, 2014:
		31-Mar-15		31-Dec-14

	Contributions from noncontrolling interests		2,475		16,064
	Changes in fair value of noncontrolling interests		11,631		89,767
	Net income		29,320		133,593
	Other comprehensive income (loss)		-3,479		-3,573
