# AAAHC accreditation: what ASCs and ambulatory practices should know

> AAAHC accredits surgery centers and other outpatient sites for three years. CMS has granted it deemed status for ASCs, so its survey can replace the state's. Medicare surveys are unannounced. Surveyors score each QI study on six parts.

## Who does AAAHC accredit?

AAAHC was founded in 1979. It says it has accredited more than 6,800 organizations. Its settings include ambulatory surgery centers, office-based surgery facilities, endoscopy centers, student and community health centers, medical and dental group practices, employer and retail clinics, and Indian and tribal health centers. It also accredits health plans and offers certifications such as Patient-Centered Medical Home.

## How does AAAHC relate to CMS deemed status?

CMS has granted AAAHC deemed status for ASCs, and for HMOs and PPOs in Medicare Advantage. Deemed status means CMS accepts the accreditor's survey in place of a state survey. An ASC picks a standard accreditation survey or a Medicare Deemed Status survey, which adds review of the Medicare requirements. Accreditation is voluntary. A deemed ASC must still meet the QAPI condition in [42 CFR 416.43](https://incidentkit.ai/compliance/cms-qapi/ambulatory-surgery-centers).

*AAAHC survey types and notice*

| Survey type | Purpose | Notice |
| --- | --- | --- |
| Initial and reaccreditation | First accreditation, or renewal after a three-year term | Public Notice of Survey posted at least 30 calendar days before |
| Medicare Deemed Status | Deemed ASC: accreditation plus review of Medicare requirements | Unannounced; dates and surveyor names are not provided |
| Random | Picked 9 to 30 months after a survey. One surveyor, may last one day, no fee | Unannounced |
| Discretionary | For cause, when concerns are raised about compliance | Any time, without advance notice |
| Early Option | Organizations under six months old that must be accredited to open or be reimbursed | Dates set after AAAHC reviews the application |

## How do AAAHC surveys work?

AAAHC awards accreditation for three years, a 1,095-day cycle, when it finds substantial compliance with its Standards. It may require intracycle activities between surveys. It can deny or revoke accreditation at any time. It calls its method peer-based and educational. It sets survey length and surveyor numbers from the application.

v44 of the Standards took effect December 16, 2025. AAAHC released v45 on August 18, 2026. Check which version applies to your survey date. This page cites no AAAHC standard numbers because numbering changes by version.

## What quality work does AAAHC expect?

AAAHC expects a quality management and improvement program that draws on many disciplines. It rests on analysis of clinical needs, risk levels and chances to improve, and joins performance indicators with risk management. AAAHC prescribes no QI method. Surveyors judge a QI study against six components.

*AAAHC six-component QI study and where incident data fits*

| Component | AAAHC asks | Incident data supplies |
| --- | --- | --- |
| 1. Purpose | Quantify the gap and why it matters | The trend that showed the problem |
| 2. Goal | A number and a date, informed by benchmarks | The baseline rate |
| 3. Gap | Why the gap exists | Investigation findings and contributing factors |
| 4. Corrective action | Targeted actions with a timeline | Actions with owner, due date and evidence |
| 5. Remeasure | Confirm the goal was met and sustained; repeat if not | The rate after the change |
| 6. Communicate | Share results and plan further remeasurement | A summary for leadership and staff |

## What documentation should an AAAHC-accredited organization keep?

- QI studies that document all six components, including remeasurement
- The incident and indicator data behind each study
- The posted Notice of Survey. For Medicare Deemed Status surveys, post it when the invoice packet arrives. Keep it up at least 30 calendar days, even past the end of the survey.
- Records of any intracycle activities
- For a deemed ASC, the QAPI evidence CMS asks for under 416.43
- The handbook for your program and version. For deemed status, that is the Accreditation Handbook for Medicare Deemed Status.

## AAAHC vs Joint Commission for ASCs

| Item | AAAHC | Joint Commission |
| --- | --- | --- |
| CMS-approved ASC program | Yes | Yes |
| Deemed survey notice | Unannounced | Unannounced or short notice for most surveys |
| Non-deemed survey notice | Public notice at least 30 calendar days before | Seven business days for resurveys of ASCs not using deemed status |
| Event expectations | Six-component QI study | Sentinel Event Policy with a 45-business-day analysis |

## Where do incident reports fit?

A study needs a baseline, a cause and a re-measurement. Structured incident records give all three. Free text does not. [IncidentKit](https://incidentkit.ai/product/incident-reporting) captures the event. [Investigations](https://incidentkit.ai/product/investigations) record the cause. [Corrective actions](https://incidentkit.ai/product/corrective-actions) hold the check that it worked.

IncidentKit runs alongside AAAHC's own accreditation platform. It does not file anything with AAAHC.

## What the rule asks for, and how IncidentKit supports it

| Requirement | IncidentKit |
| --- | --- |
| A multidisciplinary quality program based on analysis of clinical needs and risk | Structured incident records, clustered by location, shift, equipment and cause, are the starting data. |
| QI study component 3: why the gap exists | Investigations record contributing factors and five whys. Lauren drafts. A person signs. Human-authored RCA templates are rolling out. |
| QI study component 4: targeted corrective actions with a timeline | Corrective actions with owner, due date and evidence. Nothing closes until verified. |
| QI study component 5: remeasure to confirm and sustain | An effectiveness check on each action, and analytics that show the rate before and after. |
| QI study component 6: communicate results | A compliance packet gives a plain summary of events, actions and results for leadership and staff. |
| Medicare Deemed Status: CMS conditions, including 42 CFR 416.43 | The same records serve the QAPI evidence CMS asks for. See the ASC QAPI page. |

## Frequently asked questions

### Are AAAHC surveys unannounced?

Medicare Deemed Status, random and for-cause surveys are unannounced. Regular initial and reaccreditation surveys are announced, with a public Notice of Survey at least 30 calendar days ahead.

### How long does AAAHC accreditation last?

Three years, a 1,095-day cycle, if AAAHC finds substantial compliance. It can deny or revoke accreditation at any time.

### Does AAAHC require a specific QI method?

No. AAAHC sets no QI method. Surveyors judge studies on six components: purpose, goal, gap, corrective action, remeasurement and communication. AAAHC publishes a template.

### Can an ASC meet Medicare requirements through AAAHC?

Yes, with the Medicare Deemed Status survey, which stands in for a state survey. A deemed ASC must still meet 42 CFR 416.43.
