ACHC Accreditation: Which Programmes Actually Carry CMS Deeming Authority

Deeming authority is granted per programme, not per organisation. That single fact settles most of the questions people actually bring to ACHC accreditation, and it is the fact most competing pages get wrong. ACHC accredits roughly two dozen programme lines. CMS has deemed seven of them. An organisation that says “we are ACHC accredited” has told you nothing about whether the specific service line in question satisfies the Medicare Conditions of Participation.

This page states which ACHC programmes carry CMS deeming authority, with the Federal Register citation and the exact approval term for each, as verified against CMS’s own record on 26 August 2026. It also explains the survey cycle ACHC works under, why that cycle is a federal floor rather than an ACHC design choice, and where ACHC’s process genuinely differs from The Joint Commission and DNV.

What deeming actually is, and why it is granted programme by programme

Section 1865(a)(1)(A) of the Social Security Act allows a provider or supplier accredited by a CMS-approved national accrediting organisation (AO) to be deemed to meet the relevant Medicare conditions, in place of a survey by the State Survey Agency. The approval regime sits at 42 CFR part 488, principally sections 488.4, 488.5 and 488.8.

CMS is explicit about the distinction on its own accrediting-organisations page: “While CMS often refers to ‘accreditation’, its formal authority applies to deeming,” and “AOs may also offer accreditation activities outside of CMS deeming authority.” Each approval runs to a named provider type – hospitals, hospices, ambulatory surgical centres – and each carries its own effective date and expiry. There is no such thing as an organisation-wide grant.

The practical consequence: a health system that is ACHC-accredited for its home health agency is not thereby deemed for its ambulatory surgical centre. Those are two separate CMS approvals, obtained separately, expiring on different dates.

The seven ACHC programmes CMS has deemed

Each row below is taken from the final approval notice CMS published in the Federal Register. Terms are stated as CMS stated them.

Programme	Current CMS approval term	Federal Register citation
Hospital	25 September 2023 – 25 September 2027 (4 years)	88 FR 60949 (6 Sept 2023)
Critical Access Hospital (CAH)	27 December 2025 – 27 December 2031 (6 years)	91 FR 16946 (3 Apr 2026)
Ambulatory Surgical Center (ASC)	22 September 2023 – 22 September 2027 (4 years)	88 FR 61595 (7 Sept 2023)
Home Health Agency (HHA)	24 February 2025 – 24 February 2031 (6 years)	90 FR 10081 (21 Feb 2025)
Hospice	27 November 2025 – 27 November 2031 (6 years)	91 FR 16947 (3 Apr 2026)
Home Infusion Therapy (HIT)	23 April 2024 – 23 April 2030 (6 years)	89 FR 26154 (15 Apr 2024)
End-Stage Renal Disease (ESRD) facilities	11 April 2023 – 11 April 2029 (6 years)	88 FR 16981 (21 Mar 2023)

Deeming status changes. Approval terms expire, AOs must reapply, and CMS can and does grant shorter terms or decline renewal. Two of the seven terms above expire in September 2027. Treat this table as accurate on the date checked, not as a permanent statement, and re-verify against the Federal Register before relying on it for a contracting or survey-readiness decision. The method for doing that is set out further down this page.

A documented inconsistency worth knowing about

The ESRD notice (88 FR 16981) contradicts itself by one day. Its DATES header reads “applicable on April 11, 2023 through April 10, 2029”; the Term of Approval section in the body reads “effective April 11, 2023 through April 11, 2029 (6 years)”. Both appear in the same notice. Where a single day matters, the safe reading is the earlier date, and the point should be put to CMS rather than resolved by inference.

The clinical laboratory approval is a different statute

ACHC also holds CMS approval as an accreditation organisation for clinical laboratories, effective 27 March 2023 to 27 March 2029 (88 FR 18142), covering all specialty and subspecialty areas. This is granted under the Clinical Laboratory Improvement Amendments of 1988, not under section 1865, and it is a separate regime with its own requirements – see our guide to CLIA certificate types and complexity categories for how that scheme works. CMS’s notice uses the phrase “grant the ACHC deeming authority for a period of 6 years”, so the word is the same; the statutory basis is not.

One further distinction CMS itself draws: it splits deemed programmes into certified (where a State Survey Agency could have done the survey instead) and non-certified (where no state route exists and accreditation is the only path). Of ACHC’s list, home infusion therapy sits in the non-certified category. For a HIT supplier, accreditation is not a voluntary alternative to a state survey – it is the only door.

What ACHC accredits that CMS has not deemed

ACHC’s own published programme list runs to roughly two dozen accreditation programmes plus a set of separate certifications and distinctions. Named on its site but absent from the CMS deeming record above are, among others: assisted living, behavioural health, dentistry, healthcare staffing services, home care (as distinct from the deemed home health agency programme), office-based surgery, palliative care, pharmacy and compounding pharmacy (PCAB), sleep, and the standalone certifications for stroke, joint replacement, lithotripsy, telehealth and wound care.

None of that makes those programmes worthless – many are driven by state licensure, payer contracting or specialty-society expectations rather than by Medicare. But none of them produces deemed status for a Medicare condition, and an accreditation certificate for one of them should never be presented, or accepted, as evidence that a Medicare condition is satisfied.

DMEPOS deserves a specific caution because it is routinely confused with deeming. Supplier accreditation for durable medical equipment, prosthetics, orthotics and supplies is required by CMS under a separate authority in section 1834 of the Act, through a separate list of CMS-approved DMEPOS accreditation organisations. It is not section 1865 deeming, it does not appear in the part 488 approval notices, and it should be verified against CMS’s DMEPOS list rather than the AO deeming list.

The survey cycle: a federal floor, not an ACHC choice

The single most common error in accreditation content is describing a “three-year survey cycle” as though each AO picked one. It did not. 42 CFR 488.5(a)(4)(i) requires every CMS-approved AO to agree to “re-survey every accredited provider or supplier, through unannounced surveys, no later than 36 months after the prior accreditation effective date”. The same provision adds that where a statute mandates a shorter interval, the AO must adhere to that instead.

Three consequences follow, and all three are worth stating to a board:

• 36 months is a ceiling, not a schedule. CMS has stated in an approval notice that AOs “have the discretion to require and perform surveys more frequently than every 36 months”. An AO that surveys annually is exercising discretion beneath a shared floor, not operating under a different rule.
• Unannounced is regulatory, not a courtesy. The word is in the rule. Continuous readiness is the only workable posture, which is why the survey-readiness disciplines – National Patient Safety Goals, a working QAPI plan and PIP write-up, and a rehearsed immediate jeopardy removal plan – matter more than any pre-survey scramble.
• The clock runs from the prior accreditation effective date, not from the last survey date or the certificate print date. Organisations that track the wrong anchor date routinely misjudge their window.

ACHC’s public homepage does not state its survey interval, and we did not find a published cycle length on the materials retrieved on 26 August 2026. Rather than repeat a figure from a secondary source, we state the federal requirement above and recommend confirming ACHC’s own stated interval directly with ACHC for the specific programme in question.

What CMS actually asked ACHC to fix

Approval notices are more useful than marketing material because they list the gaps CMS found. In the 2023 hospital notice, the differences CMS required ACHC to close included its standards at 42 CFR 482.41(b)(2) on Life Safety Code waivers and 482.41(b)(7) on alcohol-based hand rub dispensers. On process, CMS required ACHC to align its complaint-response policies with State Operations Manual Chapter 5, to incorporate the applicable sections of NFPA 99, the Health Care Facilities Code, into its hospital accreditation process under 482.41(c), to ensure all hospital Life Safety Code surveyors were trained on both the 2012 LSC and 2012 NFPA 99, and to give surveyors guidance on citation levels for LSC deficiencies.

If you are preparing for an ACHC hospital survey, that list is a fair guide to where surveyor attention has recently been sharpened – the physical environment and Life Safety Code chapters in particular.

How ACHC compares with TJC and DNV

All three hold CMS hospital deeming authority, so the choice between them does not change whether you satisfy Medicare. What differs is process architecture and, revealingly, the length of term CMS grants.

Accreditor	Hospital programme approval term	Source
ACHC	25 Sept 2023 – 25 Sept 2027 (4 years)	88 FR 60949
The Joint Commission	15 July 2025 – 15 July 2030 (5 years)	90 FR 26587
DNV	26 Sept 2022 – 26 Sept 2026 (4 years); continued-approval application pending	87 FR 54511; 91 FR 17970

Term length is a weak signal, but it is not a meaningless one. The statutory maximum is six years under 42 CFR 488.5(e)(2)(i), and CMS grants six routinely – it gave ACHC six years for the CAH, hospice, home health, home infusion and ESRD programmes. It gave ACHC four for hospitals, and said why: “we will continue ongoing review of ACHC’s hospital processes to ensure full implementation and sustained compliance.” A shortened term signals residual CMS attention. It does not signal that deemed status is weaker; deemed is deemed.

The comparison worth reading alongside this page is our DNV vs The Joint Commission comparison, which covers the ISO 9001-derived NIAHO architecture and the annual-versus-triennial question in detail. We have not duplicated that analysis here.

A note on sourcing that constrains what this page will assert: jointcommission.org returns a bot challenge to automated retrieval and could not be read. Every Joint Commission fact above therefore comes from CMS Federal Register notices rather than from TJC’s own materials. We make no claim about TJC’s or DNV’s fees, survey products or standards manuals that we could not source from CMS.

What changes on 16 June 2027

CMS published a final rule with comment period at 91 FR 36370 on 16 June 2026, “Strengthening Oversight of Accrediting Organizations (AOs) and Preventing AO Conflicts of Interest, and Related Provisions”. Every provision takes effect 16 June 2027, one year after publication, and applies to all CMS-approved AOs including ACHC. The finalised provisions include:

• 42 CFR 488.8(i) – restrictions on fee-based consulting an AO may sell to facilities it accredits: none before an initial accreditation survey, none within the 12 months before the next scheduled re-accreditation survey, and none in response to a complaint, with bi-annual reporting to CMS.
• 488.8(j) – written consulting firewall policies.
• 488.8(k) – recusal of AO owners, surveyors and employees with an interest in a facility.
• 488.5(a)(10) – conflict-of-interest policies including separation of consulting from accreditation.
• 488.5(a)(21) – termination of accreditation within five business days of a CMS involuntary-termination notice.
• 488.5(a)(22) – annual surveyor interest declarations.
• A regulatory definition of “unannounced survey” added at 488.1.

The practical effect for organisations that buy education or consulting from their own accreditor – ACHC sells education through ACHCU and operates a certified-consultant programme – is that the 12-month blackout is anchored to the next scheduled re-accreditation survey. Mapping your survey window is therefore the prerequisite to knowing when that blackout starts.

How to verify ACHC’s deeming status yourself

Do not take a deeming claim from an accreditor’s marketing page, or from this one, without checking. The authoritative record is the Federal Register, and it is free and queryable.

1. Search the Federal Register for CMS notices naming the organisation. The public API at federalregister.gov accepts a full-text term plus an agency filter of centers-for-medicare-medicaid-services, and needs no key.
2. Search both spellings. CMS files ACHC notices under two different names – “Accreditation Commission for Health Care” and “Accreditation Commission for Healthcare”. They return different result sets. The hospital programme approval, 88 FR 60949, appears only under the second spelling. A search on the first spelling alone will tell you ACHC holds no hospital deeming, which is wrong.
3. Distinguish the proposed notice from the final one. CMS publishes an application notice inviting comment, then a final notice announcing the decision. Only the final notice carries an effective term. Titles beginning “Application From…” are frequently the proposed stage; the term appears in the DATES section and again under “Term of Approval”.
4. Read the DATES header and the Term of Approval paragraph, and note any disagreement between them, as in the ESRD notice above.
5. Cross-check the organisation against CMS’s current list of approved AOs on cms.gov. That page confirms which organisations hold approval, though not the per-programme mapping – for that, the Federal Register is the source.

Fees

This page states no ACHC fees. ACHC does not publish a fee schedule in the materials retrieved, and accreditation pricing varies by programme, organisation size and site count. Any figure circulating in secondary sources should be treated as unverified. Request a quotation from ACHC directly for the specific programme and scope.

Frequently asked questions

Is ACHC accreditation accepted by Medicare?

For the seven programmes listed above, yes – ACHC accreditation confers deemed status for the corresponding Medicare conditions, within the approval term stated. For ACHC programmes not on that list, no. Deeming is programme-specific, and there is no organisation-wide grant.

Does ACHC accredit hospitals?

Yes. CMS approved ACHC for continued recognition as a national accrediting organisation for hospitals effective 25 September 2023 through 25 September 2027 (88 FR 60949). Note that CMS granted four years rather than the six-year statutory maximum, citing continued review of ACHC’s hospital processes.

Does ACHC hold deeming authority for psychiatric hospitals?

CMS treats psychiatric hospital accreditation as a distinct deeming programme, and we found no Federal Register notice approving ACHC for it as of 26 August 2026. DNV and The Joint Commission hold psychiatric hospital programmes, and CIHQ applied for initial approval of one in 2023. If psychiatric hospital deeming is material to your decision, verify it directly with CMS rather than inferring it from ACHC’s general hospital approval.

How often does ACHC survey?

The federal requirement binding every CMS-approved AO is an unannounced re-survey no later than 36 months after the prior accreditation effective date, under 42 CFR 488.5(a)(4)(i). AOs may survey more frequently at their discretion. What happens once surveyors are on site differs by accreditor too — The Joint Commission works through tracer methodology. ACHC’s own published materials retrieved on 26 August 2026 did not state a programme-specific interval; confirm it with ACHC for your programme.

What is the difference between accreditation and deemed status?

Accreditation is a private assessment against an accreditor’s own standards. Deemed status is the federal consequence CMS attaches to accreditation by an approved AO under an approved programme, allowing the provider to satisfy Medicare conditions without a State Survey Agency survey. An organisation can be accredited without being deemed. It cannot be deemed without being accredited under an approved programme.

Does deemed status protect against a state or CMS survey?

No. CMS states plainly that a complaint may be filed with the State Survey Agency “even if the facility is accredited by a CMS-approved AO and has deemed status”. Deemed status displaces the routine certification survey, not complaint investigations, validation surveys, or the consequences of an immediate jeopardy finding.

Can ACHC lose deeming authority for a programme?

Yes. Approval terms expire and must be renewed on application; CMS may grant a shorter term, as it did for ACHC’s hospital and ASC programmes, or decline. From 16 June 2027, 42 CFR 488.5(a)(21) also requires an AO to terminate a facility’s accreditation within five business days of a CMS involuntary-termination notice.
