Also known as: Accreditation Association for Ambulatory Health Care

## What AAAHC is

AAAHC says it began in 1979 and focuses only on outpatient (ambulatory) care. It accredits these kinds of sites:

- Surgery centers
- Office-based surgery centers
- Endoscopy centers
- Student health centers
- Medical and dental group practices
- Community health centers
- Other outpatient settings

Reviews are on site, by peers, and meant to teach. Its accreditation term is a 1,095-day cycle. It offers several survey types, including Medicare Deemed Status surveys, which it says are unannounced.

## Link to CMS rules

A surgery center that picks AAAHC's Medicare Deemed Status program is surveyed by AAAHC, not the State agency (see [deemed status](https://incidentkit.ai/glossary/deemed-status)). It must still meet the [conditions for coverage](https://incidentkit.ai/glossary/conditions-for-coverage) in 42 CFR Part 416, including QAPI under 416.43.

Example: a surgery center in the program gets a State validation survey after a complaint. Being AAAHC-accredited does not stop CMS from checking the same rules.

Mix-up: accreditation is not a license, and Medicare does not require it. Some states and payers may, so check your state and contracts. See also the [comparison of AAAHC and the Joint Commission](https://incidentkit.ai/blog/aaahc-vs-joint-commission-for-ascs).

## Frequently asked questions

### Is AAAHC accreditation required for Medicare?

No. The State Operations Manual says it is voluntary. A surgery center can choose State agency surveys instead. Some states or payers have their own rules.

### How long does AAAHC accreditation last?

A 1,095-day cycle, or three years. AAAHC calls it '1095 strong': be survey-ready every day, not only on survey day.

### Are AAAHC deemed status surveys announced?

No. AAAHC says Medicare Deemed Status surveys are unannounced, with no dates or surveyor names in advance. Centers in the program must stay survey-ready year-round.
