Ladies and Gentlemen:

We have acted as special counsel to HCA Inc., a Delaware corporation (the “Company”), and HCA Healthcare Inc., a Delaware corporation (the “Parent Guarantor”), in connection with the Company’s offering pursuant to a registration statement on Form S-3 (No. 333-226709), as amended as of its most recent effective date (June 21, 2021), insofar as it relates to the Securities (as defined below) (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)) (as so amended, including the documents incorporated by reference therein but excluding Exhibit 25.1, the “Registration Statement”) and the prospectus, dated August 9, 2018, as supplemented by the prospectus supplement thereto, dated June 21, 2021 (together, the “Prospectus”), of (i) $850,000,000 aggregate principal amount of 2³/₈% Senior Secured Notes due 2031 (the “2031 Notes”) and (ii) $1,500,000,000 aggregate principal amount of 3¹⁄₂% Senior Secured Notes due 2051 (the “2051 Notes” and, together with the 2031 Notes, the “Notes”). The Notes were issued under an indenture dated as of August 1, 2011 (the “Base Indenture”), among the Company, the Parent Guarantor, Delaware Trust Company (as successor to Law Debenture Trust Company of New York), as trustee (the “Trustee”) and Deutsche Bank Trust Company Americas, as paying agent, registrar and transfer agent (the “Paying Agent”), as supplemented (i) with respect to the 2031 Notes, by the twenty-seventh supplemental indenture dated as of June 30, 2021 (the “Twenty-Seventh Supplemental Indenture”) among the Company, the Parent Guarantor, the subsidiary guarantors named on Schedule I thereto (the “Subsidiary Guarantors” and, together with the Parent Guarantor, the “Guarantors”), the Trustee and the Paying Agent and (ii) with respect to

Cleary Gottlieb Steen & Hamilton LLP or an affiliated entity has an office in each of the cities listed above.

the 2051 Notes, by the twenty-eighth supplemental indenture dated as of June 30, 2021 (the “Twenty-Eighth Supplemental Indenture” and, together with the Twenty-Seventh Supplemental Indenture, each a “Supplemental Indenture;” and the Base Indenture as supplemented by each Supplemental Indenture, each an “Indenture”) among the Company, the Parent Guarantor, the Subsidiary Guarantors, the Trustee and the Paying Agent.

In arriving at the opinions expressed below, we have reviewed the following documents:

HCA Inc., p. 3

In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such corporate, limited liability company or limited partnership records, as the case may be, of the Company and the Delaware Guarantors and such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinions expressed below.

In rendering the opinions expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that:

Insofar as the foregoing opinions relate to the validity, binding effect or enforceability of any agreement or obligation of the Company or any Guarantor, (a) we have assumed that each party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to the Company or any Guarantor regarding matters of the law of the State of New York, or as to the Company or any Delaware Guarantor regarding matters of the General Corporation Law of the State of Delaware, the Delaware Limited Liability Company Act or the Delaware Revised Uniform Limited Partnership Act, as the case may be, that in our experience normally would be applicable to general business entities with respect to such agreement or obligation), and (b) such opinions are subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity. In addition, the waiver of defenses contained in Section 12.01 and 12.07 of each Supplemental Indenture may be ineffective to the extent that any such defense involves a matter of public policy under the law of the State of New York.

We express no opinion as to the validity, binding effect or enforceability of any provisions of the Supplemental Indentures relating to the right of set-off to the extent that such provisions imply that set-off may be made without notice. We express no opinion as to Section 12.01 of each Supplemental Indenture requiring any Delaware Subsidiary Guarantor to guarantee the performance of any non-monetary obligation of the Company or any other Guarantor.

In giving the foregoing opinion relating to the validity, binding effect or enforceability of any agreement or obligation of any Subsidiary Guarantor that is not a Delaware Subsidiary Guarantor, we have assumed, without independent investigation, the correctness of the opinion of Robert A. Waterman, Senior Vice President and General Counsel of the Company, a copy of which is filed as Exhibit 5.1 to the Current Report on Form 8-K of the Parent Guarantor dated June 30, 2021 (the “June 30, 2021 8-K”), and our opinion is subject to all of the limitations and qualifications contained therein.

HCA Healthcare, Inc.

HCA Inc., p. 4

The foregoing opinions are limited to the law of the State of New York, the Delaware Limited Liability Company Act, the Delaware Revised Uniform Limited Partnership Act and the General Corporation Law of the State of Delaware.

We hereby consent to the use of our name in the Prospectus Supplement under the heading “Legal Matters” as counsel for the Company that has passed on the validity of the Securities and to the filing of this opinion letter as Exhibit 5.2 to the June 30, 2021 8-K. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Securities and Exchange Commission thereunder.

The opinions expressed herein are rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.
