AAAHC vs Joint Commission for ASCs: a fair comparison

Both can give ASCs deemed status

CMS approved the Joint Commission's ASC program for September 1, 2024 through September 1, 2030. It approved AAAHC's program in a December 2024 notice, for a term through 2029. Both can deem an ASC to meet Medicare's conditions for coverage.

Under 42 CFR 416.26, CMS may deem an ASC compliant if an approved national body accredits it. The ASC must still hold a state license where state law requires one. It must let the accreditor share survey findings with CMS.

CMS surveys a sample of deemed ASCs to check the process.

Accreditation is voluntary. The alternative is certification by the state survey agency. See deemed status.

The ASC Association lists five national accreditors: AAAHC, ACHC, DNV, the Joint Commission and Quad A. CMS gave DNV's ASC program initial approval effective December 8, 2025.

On Medicare, the two are more alike than different

They differ mostly in how they describe their approach and how they price. The table uses what each group and CMS publish. The Joint Commission pages we could open were 2025 archived copies, so check current pages.

Survey style shares a Medicare core

Both follow CMS rules, so deemed on-site work has a common core. The Joint Commission's ASC page lists what CMS expects an ASC to have ready. It is a useful checklist for either accreditor. Ask AAAHC for its equivalent.

• A list of surgical cases from the six months before the survey.
• A list of cases in the past 12 months with a transfer or death.
• Documents on your infection control program.
• At least 10 patients served, with 2 active at survey, ideally day one.
• Your electronic Statement of Conditions for the physical plant.
• Surveyors observe at least two procedures, one in full.

The styles differ in how each describes itself. AAAHC says its approach is peer-based, collaborative and educational. It uses documents, interviews and direct observation.

Its random surveys are unannounced, run 9 to 30 months after an accreditation survey, and take one day, one surveyor and no fee.

The Joint Commission describes a surveyor team matched to your specialty, with ASC standards focused on staff competency, patient assessment, medication management and infection control.

On Medicare topics, the standards match by design

CMS checks that each accreditor's standards are equivalent to its conditions for coverage before it grants deeming authority. Beyond that floor, full standards sit in manuals you must buy or request. We cannot compare them line by line.

Be wary of any article that claims to.

In 2024 CMS notices, the Joint Commission revised items such as who may perform surgery, life safety and patient rights. AAAHC revised items such as life safety code surveyor qualifications and plan of correction identifiers.

Get both manuals. List your ten highest-risk processes. See how each accreditor asks you to run them. The one that fits how your team already works is the one you can sustain between surveys.

Neither publishes fees, so get written quotes

Neither accreditor publishes a fee schedule on the pages we reviewed. Both quote from your center's details. We will not guess at dollar amounts.

• AAAHC: your application sets visit length and surveyor count, which set the fee.
• AAAHC extras: the standards handbook is sold separately.
• Joint Commission: fees depend on services and average daily census.
• Joint Commission billing: annual fees, an on-site fee in the survey year, a deposit.

Compare three-year totals, not first-year invoices. Ask what happens to the fee if a survey needs extra days or a follow-up.

The quality program stays the same either way

The surveyor will test your quality program. Under 42 CFR 416.43, an ASC must track adverse patient events, examine their causes, make improvements and make sure they last. CMS tells surveyors to ask whether you stop at the immediate cause or probe for root causes.

So the evidence file is the same: incident log, investigations, corrective actions and proof they worked. If a survey finds deficiencies, you write a plan of correction. See what to put in a plan of correction.

IncidentKit is not an accreditor. It keeps the evidence in one place: compliance packets and an audit trail. See ASC survey readiness and the CMS QAPI page for ASCs.

Choose on fit and a written quote

Both are legitimate routes to the same Medicare outcome. Neither is better for every center.

1. Ask each for a sample on-site agenda and expected survey length.
2. Ask how surveyors are matched to your specialty, such as orthopedics or endoscopy.
3. Request a written three-year fee estimate, including manuals and extra days.
4. Check which accreditor your state agency, payers and hospital partners recognize.
5. Talk to two ASC leaders in your specialty who have done each survey.
6. Name who owns readiness between surveys.

See the survey and accreditation readiness guide.
