Mail Stop 4561 								November 10, 2005 Wayne A. Schellhammer President and Chief Executive Officer American Caresource Holdings, Inc. 8080 Tri-Star Drive Irving, Texas 75063 Re:	American Caresource Holdings, Inc. 	File No. 333-122820 Dear Mr. Schellhammer: We have reviewed your filing and have the following comments. Where indicated, we think you should revise your document in response to these comments. If you disagree, we will consider your explanation as to why our comment is inapplicable or a revision is unnecessary. Please be as detailed as necessary in your explanation. In some of our comments, we may ask you to provide us with supplemental information so we may better understand your disclosure. After reviewing this information, we may or may not raise additional comments. 	Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filing. We look forward to working with you in these respects. We welcome any questions you may have about our comments or any other aspect of our review. Feel free to call us at the telephone numbers listed at the end of this letter. General 1. We have reviewed your response letter, dated November 3, 2005. It appears that shares of ACS common stock were offered and sold as part of the Patient InfoSystems` private placement using a non- conforming prospectus under Section 10 of the Securities Act. Since those purchasers have already made an investment decision regarding the ACS shares, they may not receive shares as part of the registered offering. As a result, the ACS shares sold in the private placement are restricted securities that may be resold only through registration or an applicable exemption from registration. If you choose to register these shares for resale, please revise the SB-2 to include the information required by Items 507 of Regulation S-B. Finally, please revise the SB-2 to include risk factor disclosure regarding any material potential contingent liability the company may face with respect to the sale of such shares. As appropriate, please amend your registration statement in response to these comments. You may wish to provide us with marked copies of the amendment to expedite our review. Please furnish a cover letter with your amendment that keys your responses to our comments and provides any requested supplemental information. Detailed cover letters greatly facilitate our review. Please understand that we may have additional comments after reviewing your amendment and responses to our comments. We will consider a written request for acceleration of the effective date of the registration statement as a confirmation of the fact that those requesting acceleration are aware of their respective responsibilities under the Securities Act of 1933 and the Securities Exchange Act of 1934 as they relate to the proposed public offering of the securities specified in the above registration statement. We will act on the request and, pursuant to delegated authority, grant acceleration of the effective date. We direct your attention to Rules 460 and 461 regarding requesting acceleration of a registration statement. Please allow adequate time after the filing of any amendment for further review before submitting a request for acceleration. Please provide this request at least two business days in advance of the requested effective date. 	You may contact Howard Efron, Accountant, at (202) 551-3439 or Cicely Luckey, Accounting Branch Chief, at (202) 551-3413 if you have questions regarding comments on the financial statements and related matters.
