Ladies and Gentlemen:

I am Senior Vice President and General Counsel of HCA Inc., a Delaware corporation (the “Company”). The Company, HCA Healthcare, Inc., a Delaware corporation and the direct parent of the Company (“Parent Guarantor”), and the subsidiaries of the Company listed on Schedules I and II hereto (collectively, the “Subsidiary Guarantors” and together with the Parent Guarantor, the “Guarantors”) have filed a Registration Statement on Form S-3 (File No. 333-226709) (as amended as of its most recent effective date (June 21, 2021), the “Registration Statement”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to which the Company is issuing $850,000,000 aggregate principal amount of 2 3/8% Senior Secured Notes due 2031 (the “2031 Notes”) and $1,500,000,000 aggregate principal amount of 3 1/2% Senior Secured Notes due 2051 (the “2051 Notes” and, together with the 2031 Notes, the “Notes”), each unconditionally guaranteed (collectively, the “Guarantees” and, together with the Notes, the “Securities”) (i) on a senior unsecured basis by the Parent Guarantor and (ii) jointly and severally, on a senior secured basis by each of the Subsidiary Guarantors, pursuant to the Underwriting Agreement dated June 21, 2021 (the “Underwriting Agreement”), among the Company, the Parent Guarantor, the Subsidiary Guarantors and the underwriters named therein.

In connection with this opinion, I have reviewed the Registration Statement insofar as it relates to the Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)) and the prospectus dated August 9, 2018 (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement, dated June 21, 2021 (including the documents incorporated therein by reference, together with the Base Prospectus, the “Preliminary Prospectus”), filed pursuant to Rule 424(b) under the Securities Act and the prospectus supplement dated June 21, 2021 (including the documents incorporated therein by reference, together with the Base Prospectus, the “Prospectus”), filed pursuant to Rule 424(b) under the Securities Act; and the free writing prospectus listed on Annex A to the Underwriting Agreement (such free writing prospectus, together with the Preliminary Prospectus, the “Pricing Disclosure Package”). I have also examined the following:

(i)    the 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 (in such capacity, the “Trustee”) and Deutsche Bank Trust Company Americas, as registrar, paying agent and transfer agent (the “Registrar”);

(ii)    the Supplemental Indenture No. 27 for the 2031 Notes, dated as of June 30, 2021, among the Company, the Parent Guarantor, the Subsidiary Guarantors, the Trustee and the Registrar (the “Twenty-Seventh Supplemental Indenture”);

(iii)    the Supplemental Indenture No. 28 for the 2051 Notes, dated as of June 30, 2021, among the Company, the Parent Guarantor, the Subsidiary Guarantors, the Trustee and the Registrar (the “Twenty-Eighth Supplemental Indenture” and, together with the Twenty-Seventh Supplemental Indenture, each a “Supplemental Indenture” and together the “Supplemental Indentures;” and the Base Indenture as supplemented by each Supplemental Indenture, each an “Indenture”);

(iv)    duplicates of the global certificates representing the Notes;

(v)    the Guarantees whose terms are set forth in each of the Supplemental Indentures; and

(vi)    the Underwriting Agreement.

In rendering the opinions contained herein, I have relied upon my examination or the examination by members of our legal staff or outside counsel (in the ordinary course of business) of

the original or copies certified or otherwise identified to our satisfaction of the charter, bylaws or other governing documents of the subsidiaries named in Schedule I hereto (the “Schedule I Subsidiaries”), resolutions and written consents of their respective boards of directors, general partners, managers and managing members, as the case may be, statements and certificates from officers of the Schedule I Subsidiaries and, to the extent obtained, from various state authorities, status telecopies provided by Corporation Service Company and CT Corporation, and such other documents and records relating to the Schedule I Subsidiaries as we have deemed appropriate. I, or a member of my staff, have also examined the originals, or duplicates or certified or conformed copies, of such corporate and other records, agreements, documents and other instruments of all the registrants and have made such other investigations as I have deemed relevant and necessary in connection with the opinions hereinafter set forth. As to questions of fact material to this opinion, I have relied upon certificates or comparable documents or statements of public officials and of officers and representatives of the Company, the Parent Guarantor and the Schedule I Subsidiaries.

In rendering the opinions set forth below, I have also assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, I am of the opinion that: (1) each of the Schedule I Subsidiaries is validly existing as a corporation, limited liability company, limited partnership or partnership, as applicable, under the law of its jurisdiction of organization and has full corporate, limited liability company, limited partnership or partnership power and authority, as the case may be, to issue the Guarantees and (2) each Supplemental Indenture has been duly authorized, executed and delivered by each of the Schedule I Subsidiaries.

This opinion letter is given as of the date hereof, and I assume no obligation to update or supplement this opinion letter to reflect any facts or circumstances that may hereafter come to my attention or any change in laws that may hereafter occur.

I hereby consent to the filing of this opinion letter as Exhibit 5.1 to the Current Report on Form 8-K of the Parent Guarantor filed with the Commission in connection with the registration of the Notes and to the use of my name under the caption “Legal Matters” in the Prospectus included in the Registration Statement.
