ASC Central

Choosing an ASC Accreditation Organization

The five organizations that hold CMS deeming authority for ambulatory surgery centers as of August 2026, how they differ, and the 2026 rule that changes what they are allowed to sell you.

As of August 2026, five organizations hold CMS deeming authority for ambulatory surgery centers: AAAHC, The Joint Commission, ACHC, QUAD A and DNV. DNV is the newcomer, granted initial ASC approval in December 2025 — the first addition to this field in years.

Accreditation is voluntary. CMS says so in its own State Operations Manual. A center may be surveyed by the state agency instead, and accreditation never substitutes for state licensure, which is a Condition for Coverage in its own right.

Approval terms verified against Federal Register final notices on 19 August 2026. Sources listed at the foot of the page.

The five organizations and their approval terms

Deeming authority is granted by CMS through Federal Register notice for a defined term, not indefinitely. Knowing when your accreditor’s term expires is worth five minutes: a renewal cycle is when CMS reviews the organization’s standards and survey process against the Conditions for Coverage, and it is when the comment docket is open.

Accreditor Full name Controlling notice Current ASC approval term
AAAHC Accreditation Association for Ambulatory Health Care, Inc. 89 FR 100498, 12 December 2024 20 November 2024 to 20 November 2029
TJC The Joint Commission 89 FR 58380, 18 July 2024 1 September 2024 to 1 September 2030 (6 years, the statutory maximum)
QUAD A American Association for Accreditation of Ambulatory Surgery Facilities, doing business as QUAD A 89 FR 89014, 12 November 2024 27 November 2024 to 27 November 2029
ACHC Accreditation Commission for Health Care, Inc. 88 FR 61595, 7 September 2023 22 September 2023 to 22 September 2027 (4 years)
DNV DNV Healthcare, Inc. 90 FR 56766, 8 December 2025 — initial approval 8 December 2025 to 10 December 2029

Two CMS documents still in circulation are out of date. A CMS PDF listing ASC accrediting organizations still names HFAP and IMQ; neither holds current ASC deeming authority. A separate CMS complaint-contact list dated July 2022 is correct for the four incumbents but predates DNV. If you are checking a list, check its date.

If you are with ACHC, note the date. ACHC holds the shortest current term of the five, expiring 22 September 2027. Renewal is routine and CMS raised no concerns in the 2023 notice, but it is the next ASC deeming decision due.

How they actually differ

Every one of these organizations surveys against the same Conditions for Coverage, and CMS requires all of them to conduct unannounced surveys. The differences that matter to an administrator are structural.

Accreditor Cycle Structure and character
AAAHC 3 years Medicare Deemed Status surveys are unannounced, with no advance notice of date or surveyor names. Publishes the most detailed list of what comes with accreditation: an accreditation management system, survey-readiness events, benchmarking studies and quality improvement tools. Standards are sold as a handbook; the chapter structure is not published openly.
TJC 3 years Tracer-driven. The published survey activity guide states most survey activity happens during individual tracers of 60 to 120 minutes. For a deemed ASC survey it specifies at least two active patients preferred on day one, observation of at least one complete surgical procedure, a medical record sample of at least 10 records (20 above 50 cases a month), a mandatory Life Safety Code and Health Care Facilities Code assessment and a roughly 60-minute emergency management session. Standards are in the ambulatory care manual.
QUAD A 3 years The most prescriptive and the most binary. Its manual requires 100 percent compliance with every standard, without exception, and a single instance of non-compliance generates a deficiency. Standards run in 13 numbered sections from basic mandates through life safety, cited in a section-subsection-standard format. Its deficiency process is also the most concretely published: report within 10 business days, plan of correction due in 10 calendar days, evidence of correction in 30 days, follow-up survey within 45 days for condition-level findings, and a maximum of two follow-up surveys.
ACHC 3 years Publishes an accreditation-101 overview and a program aimed at new centers that concludes with a deficiency report and a faster plan of correction. Cites an annual academy, monthly sessions and a library of tools and templates. Standards manual is sold; chapter structure not published openly. ACHC also sells ASC consulting separately, which the 2026 CMS rule directly affects.
DNV 3-year cycle with annual on-site surveys The structural outlier. Every other ASC accreditor does a triennial on-site with no routine annual visit; DNV conducts annual collaborative surveys with full-time rather than contract surveyors. Its NIAHO standards wrap the Conditions for Coverage in an ISO 9001 quality management architecture — DNV states it is the only accreditor integrating ISO 9001 into healthcare. Offered to both deemed and non-deemed centers.

The annual-visit question is the real fork in the road. DNV’s model trades a bigger triennial event for a smaller annual one. Whether that is an advantage depends on your center: it forces continuous readiness and gives you an outside set of eyes every year, and it is a recurring cost and a recurring disruption. Everything else on this page is a matter of degree; that one is a genuinely different operating model.

On market share. No accreditor and no primary source publishes reliable ASC accreditation market share figures. Numbers circulating in trade press and vendor material are not sourced to anything verifiable. We have deliberately left them out rather than repeat them.

What each one publishes about cost

Only one of the five publishes actual dollar amounts.

  • QUAD A publishes a full fee schedule: annual fees tiered by physician count, specialties and facility size, plus a separate full survey fee by size, a Life Safety Code survey fee required of all ASC facilities, and published rates for follow-up surveys with a maximum of two.
  • The Joint Commission publishes the fee structure — an annual fee billed each January and prorated for new applicants, an on-site survey fee billed after survey once every three years covering surveyor travel, and a deposit paid at application and credited against future invoices — but its ASC-specific dollar figures were not retrievable from its public pages.
  • AAAHC states that application fees are non-refundable and that survey fees are customized by organization type, size and services, and directs prospects to contact them. No figures published.
  • ACHC asserts no annual fees on its ASC page but publishes no survey or application pricing.
  • DNV publishes no fees.

We are not going to estimate the four that do not publish. If you are comparing, get written quotes and make sure each one is quoting the same thing — the Life Safety Code survey in particular is sometimes separate and sometimes bundled, and follow-up survey pricing is where a difficult survey gets expensive.

Accreditation, licensure and deemed status

Three things that get conflated, and should not be.

Accreditation is voluntary

CMS State Operations Manual Chapter 2, section 2003C: accreditation under a CMS-approved Medicare accreditation program “is voluntary and is not required for Medicare participation.” Deemed status is framed as an alternative to state agency surveys for demonstrating compliance — not as a higher standard and not as a prerequisite.

Deemed status changes who surveys you, not whether you can be surveyed

For a deemed center, the state agency does not conduct the initial or recertification survey. It retains complaint authority, and CMS may direct a validation survey to check the accreditor’s work. Appendix L states that state agencies may survey a deemed ASC when authorized by the CMS location.

Accreditation does not replace state licensure

42 CFR 416.40 is a standalone Condition for Coverage: “The ASC must comply with State licensure requirements.” Appendix L instructs surveyors that in states requiring a separate facility license, the center must hold a current license that has not expired, been suspended or been revoked, and that verifying the licenses of individual personnel is the center’s responsibility.

Whether a state will accept an accreditor’s survey in place of its own licensure survey is a state-by-state question. AAAHC publicizes one such recognition — the Oregon Health Authority, for ASC relicensure. That is one state, not a general rule. Check yours specifically rather than assuming.

The 2026 rule that changes the relationship

CMS published a final rule with comment period on 16 June 2026 — Strengthening Oversight of Accrediting Organizations and Preventing AO Conflict of Interest, CMS-3367-FC, 91 FR 36370. It is effective 16 June 2027, so nothing in it applies today, but it is worth understanding now because it changes what your accreditor can sell you.

The provisions that reach an ASC:

  • Accreditors must incorporate the applicable Medicare conditions as minimum accreditation standards.
  • Accreditor surveyors must complete CMS online training.
  • Surveys must be unannounced and unpredictable — codifying what had been policy.
  • Accreditor owners, surveyors and employees, and their immediate family, are barred from participating in surveys of facilities in which they hold an interest.
  • Fee-based consulting is prohibited before an initial accreditation survey and restricted within 12 months before a re-accreditation survey, with required firewall policies and twice-yearly consulting reports to CMS.
  • Where an accreditor scores unacceptably on a CMS direct-observation validation survey, its correction plan is publicly reported.
  • Providers terminated from Medicare cannot re-enter through accreditation.

The consulting restriction is the one to plan around. If you currently buy readiness consulting from the same organization that accredits you — several of them sell it — that arrangement has to change before your first re-accreditation survey after June 2027. Better to restructure it deliberately on your own timeline than to discover it 11 months out.

Common questions

Which accrediting organizations can accredit an ASC for Medicare?

Five as of August 2026: the Accreditation Association for Ambulatory Health Care (AAAHC), The Joint Commission, the Accreditation Commission for Health Care (ACHC), QUAD A, and DNV Healthcare. DNV received initial CMS approval for its ASC accreditation program by Federal Register notice at 90 FR 56766 on 8 December 2025. Two organizations that formerly appeared on CMS ASC lists, HFAP and IMQ, no longer hold ASC deeming authority, and some CMS PDFs still in circulation have not been updated to reflect either change.

Is accreditation required for an ASC to bill Medicare?

No. CMS State Operations Manual Chapter 2 section 2003C states that accreditation under a CMS-approved program is voluntary and is not required for Medicare participation. A center may instead be surveyed and certified by its state survey agency. Accreditation with deemed status is an alternative route to demonstrating compliance with the Conditions for Coverage, not a requirement. Separately, accreditation never satisfies state licensure, which is its own Condition for Coverage at 42 CFR 416.40.

How long is an ASC accreditation cycle?

Three years for all five organizations. DNV is structurally different: it operates a three-year accreditation cycle with annual on-site collaborative surveys conducted by full-time surveyors, whereas AAAHC, The Joint Commission, ACHC and QUAD A conduct a triennial on-site survey with no routine annual visit. CMS requires surveys to be unannounced, and the 2026 accreditor oversight rule codifies that they must also be unpredictable, effective 16 June 2027.

How much does ASC accreditation cost?

Only QUAD A publishes actual dollar figures, in a fee schedule covering annual fees tiered by size, full survey fees, a separately priced Life Safety Code survey required of all ASC facilities, and follow-up survey rates. The Joint Commission publishes its fee structure — an annual fee, an on-site survey fee billed once every three years including surveyor travel, and an application deposit — but not ASC-specific amounts on its public pages. AAAHC, ACHC and DNV do not publish pricing. When comparing quotes, confirm whether the Life Safety Code survey and any follow-up surveys are included, since that is where costs diverge most.

Can my accreditor also sell me consulting?

Today, yes, and several do. That changes on 16 June 2027, when the CMS final rule at 91 FR 36370 takes effect. It prohibits fee-based consulting by an accrediting organization before an initial accreditation survey, restricts consulting within the 12 months before a re-accreditation survey, requires firewall policies, and requires accreditors to report their consulting activity to CMS twice a year. Centers that currently buy readiness consulting from their own accreditor should plan to restructure that relationship before their first re-accreditation survey after that date.

Will a state survey still visit an accredited ASC?

It can. Deemed status means the state agency does not perform the routine initial or recertification survey, but it retains authority to conduct complaint surveys, and CMS may direct validation surveys to verify the accreditor’s work. Appendix L states that state agencies may survey a deemed ASC when authorized by the CMS location. State licensure surveys are separate again and follow state rules.

Preparing for the survey is the same work either way

Whoever walks through the door is measuring you against the same Conditions for Coverage. ASC Central members get the regulatory updates, live conferences and readiness resources that keep a center survey-ready regardless of which organization holds the clipboard.

This page describes publicly documented differences between accrediting organizations as of the verification date shown above, drawn from Federal Register notices, CMS manuals and each organization’s own published materials. It is not an endorsement of any organization, not legal advice, and not a substitute for the current standards manual of the accreditor you are considering. Several accreditors do not publish their standards structure, fees or deficiency procedures publicly; those gaps are stated as gaps rather than filled with estimates.
