CMS deeming authority is CMS approval of a national accrediting organization's accreditation program, which CMS says is "granted by CMS after a formal review of an AO's standards and survey processes" (CMS). This page is for national accrediting organizations applying for approval of a program, or for re-approval, under 42 CFR Part 488, Subpart A. The section 488.5 application covers CMS's certified provider and supplier programs. CMS approves some non-certified programs under separate regulations: diabetes self-management training under 42 CFR 410.142 and advanced diagnostic imaging under 42 CFR 414.68, which this page does not cover. We did not confirm the approval regulations for home infusion therapy or clinical laboratories. Integral Healthcare Solutions (IHS) builds the survey, surveyor and decision procedures and the Medicare crosswalk; your experts own the standards, and your organization files the application.

What is CMS deeming authority?
CMS describes the role of accrediting organizations (AOs) this way: "AOs play a key role in determining whether health care providers and suppliers meet the Medicare health and safety requirements" (CMS, Accrediting Organizations). To be approved, an organization must "demonstrate that it meets all requirements per 42 CFR 488.1, 488.4, 488.5, and 488.8" (same page).
The governing text is 42 CFR Part 488, Subpart A. Section 488.5 is titled "Application and re-application procedures for national accrediting organizations," and section 488.8 is "Ongoing review of accrediting organizations." We read the current eCFR text on 2 October 2026. Under 42 CFR 488.5(a), an applicant "must furnish CMS with all of the following information and materials to demonstrate that the program provides reasonable assurance that the entities accredited under the program meet or exceed the applicable Medicare conditions or requirements."
A change is coming. On June 16, 2026, CMS published a final rule with comment period, "Medicare Program; Strengthening Oversight of Accrediting Organizations (AOs) and Preventing AO Conflicts of Interest, and Related Provisions," at 91 FR 36370 (Federal Register). The Federal Register record lists an effective date of June 16, 2027, and the eCFR text of 488.4, 488.5 and 488.8 now links to amendments from that rule. This page describes the current text. We have not reviewed the amended text, so an application planned for filing near or after the effective date should be read against it.
Who needs it and what triggers it
The buyer is a national accrediting organization that wants CMS to approve one of its accreditation programs, or that holds approval and needs it renewed. Three events start the work:
- A first application for a program. Section 488.5(a) applies to an organization "applying to CMS for approval or re-approval of an accreditation program under § 488.4."
- Re-approval at the end of a term. The final notice approving a program sets its term, which "will not exceed 6 years" (42 CFR 488.5(e)(2)). Re-approval uses the same section 488.5 application.
- A new provider or supplier type. The application must name "The type of provider or supplier accreditation program for which the organization is requesting approval" (42 CFR 488.5(a)(2)). IHS's reading, October 2026: an organization adding a provider type should plan for a separate program application. CMS's text as we read it does not address add-ons directly.
CMS lists the program types that have CMS-approved accrediting organizations. CMS lists these certified programs: ambulatory surgical centers, critical access hospitals, end stage renal disease facilities, home health agencies, hospice, hospitals (including psychiatric hospitals), outpatient physical therapy, rural health clinics and clinical laboratories (CLIA). Its non-certified programs are advanced diagnostic imaging, diabetes self-management training and home infusion therapy (CMS).
How IHS helps
IHS works through the application the way the regulation lays it out, item by item, and drafts the operating documents an approved program has to run on. The process:
- Gap assessment. Your standards, survey process and governance are read against each item 42 CFR 488.5 requires, and each gap is written down with the paragraph it comes from.
- Crosswalk. IHS builds the table section 488.5(a)(3) calls for, matching each applicable Medicare condition or requirement to "the exact language of the organization's comparable accreditation requirements and standards."
- Drafting. IHS drafts the survey process, surveyor qualification and training, conflict-of-interest, complaint and accreditation-decision procedures for your experts to review and approve.
- Evidence mapping. Each section 488.5(a) item is tied to the document in your file that answers it.
- Mock review. IHS reviews the assembled package against the regulation as a reviewer would, and lists what is missing or thin.
- Readiness support. IHS drafts application text for your organization to submit and helps you prepare answers if CMS returns questions.
What you supply: your standards, survey tools, surveyor files, governance documents, the subject-matter experts who approve the standards and survey judgments, and your counsel.
The limit: IHS does not set clinical standards. Your experts decide what each standard requires. Your organization files the application and handles all correspondence with CMS; IHS drafts, and you submit.
What to have ready
Each item below comes from 42 CFR Part 488, Subpart A, current eCFR text read 2 October 2026.
- Documentation that the organization meets the definition of a "national accrediting organization" in 42 CFR 488.1, which means it accredits provider entities under a specific program and its accredited entities under each program are widely located geographically across the United States (488.5(a)(1)).
- A statement of the program type you are asking CMS to approve, per 42 CFR 488.5(a)(2).
- Your current standards in a form that can be quoted exactly, since the crosswalk must show "the exact language of the organization's comparable accreditation requirements and standards" (488.5(a)(3)).
- A list of the Medicare conditions or requirements that apply to the program type, to anchor the crosswalk table (488.5(a)(3)).
- A written survey process that includes "an agreement by the organization to re-survey every accredited provider or supplier, through unannounced surveys, no later than 36 months after the prior accreditation effective date" (488.5(a)(4)(i)).
- Your surveyor education and experience requirements, since the application needs "A description of the education and experience requirements surveyors must meet" (488.5(a)(7)).
- Conflict-of-interest policies covering "individuals who conduct surveys or participate in accreditation decisions," including the appearance of conflicts (488.5(a)(10)).
- Awareness that after approval CMS reviews "the rate of disparity between certifications of the accrediting organization and certifications of the SA" (42 CFR 488.8(a)). IHS's reading, October 2026: have a way to track your own results against state survey agency findings.
- A list of all facilities currently accredited under the program, with type, category and expiration date of each accreditation (488.5(a)(14)).
- A schedule of all surveys expected in the 6 months after you submit (488.5(a)(15)).
- The three most recent audited financial statements (488.5(a)(16)).
- A filing calendar that allows for the 30-day public comment period and the 210-day window for CMS's final notice (488.5(e)).
- A note to re-read sections 488.4, 488.5 and 488.8 as amended by 91 FR 36370. A complete application filed after November 18, 2026 could have its 210-day window run past June 16, 2027.
The introductory call is the place to walk through this list against your own program.
How it compares
An accrediting organization has more than one route, and each fits a different goal:
| Route | What it involves | Basis |
|---|---|---|
| CMS approval of a new program | Full section 488.5 application, public comment, final notice with a term of up to 6 years | 42 CFR 488.5(a), (e) |
| Re-approval of an approved program | The same section 488.5 application, filed for "approval or re-approval" | 42 CFR 488.5(a) |
| Adding a provider or supplier type | IHS's reading (October 2026): a separate program application naming the new type | 42 CFR 488.5(a)(2) |
| Private accreditation without deeming | IHS's reading (October 2026): for certified provider types, accredited providers would still go through state survey agency certification for Medicare, because 488.4(a) ties deemed status to a "CMS-approved accreditation program." CMS's page says non-certified suppliers (advanced diagnostic imaging, diabetes self-management training, home infusion therapy) cannot be surveyed by the state, so this row does not apply to them. | 42 CFR 488.4(a) |
Other federal approval routes for assurance bodies run under different authorities and serve different buyers: SAMHSA approval of opioid treatment program accrediting bodies, ONC authorization of health IT certification bodies and ONC authorization of health IT testing laboratories.
What it costs
The cost of an application is mostly the staff and expert time to build the package. CMS does not publish a fee schedule on the pages we reviewed, and the list of required materials in 42 CFR 488.5(a) as read on 2 October 2026 names no application fee. IHS's fee depends on scope. IHS scopes each engagement after a free introductory call.
What this is not
- IHS is not an accrediting organization and does not grant, influence or predict CMS's decision on an application.
- IHS does not submit to CMS or act for your organization before CMS. Your organization files and corresponds.
- This page is not legal advice. Your counsel advises on the regulation and the pending amendments.
Frequently asked questions
What is CMS deeming authority for an accrediting organization?
It is CMS approval of an accrediting organization's accreditation program, which CMS says is "granted by CMS after a formal review of an AO's standards and survey processes." The organization must "demonstrate that it meets all requirements per 42 CFR 488.1, 488.4, 488.5, and 488.8" (CMS).
Which provider and supplier types can a CMS-approved accrediting organization deem?
CMS lists approved accrediting organizations for hospitals, critical access hospitals, ambulatory surgical centers, end stage renal disease facilities, home health agencies, hospice, outpatient physical therapy, rural health clinics and clinical laboratories. It also lists non-certified programs: advanced diagnostic imaging, diabetes self-management training and home infusion therapy (CMS). The section 488.5 application on this page does not govern the non-certified programs.
What does a CMS accrediting organization application have to include under 42 CFR 488.5?
Section 488.5(a) lists the materials. They include the program type, a detailed crosswalk to the Medicare conditions or requirements, a description of the survey process with a commitment to unannounced re-surveys within 36 months, surveyor education and experience requirements, and conflict-of-interest policies (42 CFR 488.5(a)).
How do we build the crosswalk from Medicare conditions to our standards?
Section 488.5(a)(3) asks for "A detailed crosswalk (in table format) that identifies, for each of the applicable Medicare conditions or requirements, the exact language of the organization's comparable accreditation requirements and standards." The work is one row per condition or requirement, with your standard quoted exactly beside it, and any condition without a matching standard marked as a gap.
How long does CMS take to approve an accrediting organization application?
Once CMS has a complete application, it publishes a proposed notice that "provides 30 calendar days for the public to submit comments." CMS then "publishes a final notice within 210 calendar days from the date CMS determines the AO's applications was complete," except for skilled nursing facility programs (42 CFR 488.5(e)). The clock runs from completeness, so an incomplete package adds time before it starts.
How long does CMS approval of an accreditation program last?
The final notice sets the term of approval, which "will not exceed 6 years" (42 CFR 488.5(e)(2)). Re-approval goes through the same section 488.5 application, which covers "approval or re-approval" of a program.
What surveyor qualification and conflict-of-interest policies does CMS expect?
The application must include "A description of the education and experience requirements surveyors must meet" (42 CFR 488.5(a)(7)). It must also include policies "to avoid conflicts of interest, including the appearance of conflicts of interest, involving individuals who conduct surveys or participate in accreditation decisions" (488.5(a)(10)).
What does the June 2026 CMS final rule on accrediting organization oversight change?
The rule, "Medicare Program; Strengthening Oversight of Accrediting Organizations (AOs) and Preventing AO Conflicts of Interest, and Related Provisions," was published at 91 FR 36370 on June 16, 2026, with an effective date of June 16, 2027 per the Federal Register record. It amends sections 488.4, 488.5 and 488.8. We have not reviewed the amended text, so we do not summarize its changes here.
How does CMS monitor an accrediting organization after approval?
"CMS evaluates the performance of each CMS-approved accreditation program on an ongoing basis." That includes "Analysis of the results of the validation surveys under § 488.9(a)(1), including the rate of disparity between certifications of the accrediting organization and certifications of the SA" (42 CFR 488.8(a)).
