Ladies and Gentlemen:

We refer to the Registration Statement on Form S-3, File No. 333-203394 (the “Registration Statement”), filed by DaVita HealthCare Partners Inc., a Delaware corporation (the “Company”), and the direct and indirect subsidiaries of the Company listed in Exhibit A hereto (collectively, the “Guarantors”) with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”), which Registration Statement became effective upon filing pursuant to Rule 462(e) under the Securities Act. Pursuant to the Registration Statement, the Company is issuing $1,500,000,000 aggregate principal amount of the Company’s 5.000% Senior Notes due 2025 (the “Notes”), and the Guarantors are issuing their guarantees of the Notes (the “Guarantees”, and together with the Notes, the “Securities”). The Securities are being issued under an indenture dated as of April 17, 2015 (the “Indenture”) among the Company, the Guarantors and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”). The Securities are to be sold by the Company pursuant to an underwriting agreement dated April 14, 2015 (the “Underwriting Agreement”), by and among the Company, the Guarantors and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative of the several underwriters named therein.

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

We have examined the Registration Statement, the prospectus, dated April 14, 2015, included in the Registration Statement, the preliminary prospectus supplement, dated April 14, 2015, filed with the SEC pursuant to Rule 424(b) under the Securities Act, the final prospectus supplement, dated April 14, 2015, filed with the SEC pursuant to Rule 424(b) under the Securities Act, the Indenture, the Underwriting Agreement, the Securities in global form and the resolutions adopted by the board of directors of the Company relating to the Registration Statement, the Indenture, the Underwriting Agreement and the issuance of the Notes by the Company and the resolutions adopted by the board of directors or similar governing body of each Guarantor set forth on Exhibit B (each, a “Specified Guarantor”, and collectively, the “Specified Guarantors”) relating to the Registration Statement, the Indenture, the Underwriting Agreement and the issuance by such Specified Guarantor of its Guarantee. We have also examined originals, or copies of originals certified to our satisfaction, of such agreements,

documents, certificates and statements of the Company and the Specified Guarantors and other corporate, limited liability company or limited partnership, as the case may be, documents and instruments, and have examined such questions of law, as we have considered relevant and necessary as a basis for this opinion letter. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all persons and the conformity with the original documents of any copies thereof submitted to us for examination. As to facts relevant to the opinions expressed herein, we have relied without independent investigation or verification upon, and assumed the accuracy and completeness of, certificates, letters and oral and written statements and representations of public officials and officers and other representatives of the Company and the Guarantors.

Based on and subject to the foregoing and the other limitations and qualifications set forth herein, we are of the opinion that, when the Notes have been duly authenticated by the Trustee in accordance with the Indenture and the Securities have been delivered to the purchasers of the Securities and paid for as provided in the Underwriting Agreement, the Notes will be the validly issued and binding obligations of the Company and the Guarantees will be valid and binding obligations of the Guarantors.

Our opinion is subject to bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, fraudulent transfer and other similar laws relating to or affecting creditors’ rights generally and to general equitable principles (regardless of whether considered in a proceeding in equity or at law), including concepts of commercial reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief.

With respect to each instrument or agreement referred to in or otherwise relevant to the opinions set forth herein (each, an “Instrument”), we have assumed, to the extent relevant to the opinions set forth herein, that (i) each party to such Instrument (if not a natural person) was duly organized or formed, as the case may be, and was at all relevant times and is validly existing and in good standing under the laws of its jurisdiction of organization or formation, as the case may be, and had at all relevant times and has full right, power and authority to execute, deliver and perform its obligations under such Instrument, (ii) such Instrument has been duly authorized, executed and delivered by each party thereto, and (iii) such Instrument was at all times and is a valid, binding and enforceable agreement or obligation, as the case may be, of each party thereto; provided that (x) we make no such assumption in clause (i) or (ii) insofar as such assumption relates to the Company or the Specified Guarantors and (y) we make no assumption in clause (iii) insofar as such assumption relates to the Company or any Guarantor. We have also assumed that no event has occurred or will occur that would cause the release of the Guarantee by any Guarantor under the terms of the Indenture.

This opinion letter is limited to the laws of the States of California, Illinois, New York and Texas and the Delaware General Corporation Law, the Delaware Limited Liability Company Act and the Delaware Revised Uniform Limited Partnership Act. We express no opinion as to the laws, rules or regulations of any other jurisdiction, including, without limitation, the federal laws of the United States of America or any state securities or blue sky laws.
