Medicare Deemed Status Accreditation

Earn Medicare Deemed Status with AAAHC

AAAHC holds “deeming authority” from the Centers for Medicare & Medicaid Services (CMS) to conduct deemed status accreditation for ambulatory surgical centers (ASCs).

MDS accreditation may only be requested by a currently Medicare certified ASC or one that is seeking Medicare certification. Any other associated entity must request accreditation separately from the ASC seeking MDS.

MDS surveys are unannounced. Specific survey date and surveyor names are not provided for Medicare Deemed Status surveys.

*Application fees are non-refundable. MDS surveys are unannounced. Specific survey date and surveyor names are not provided for AAAHC/MDS surveys.

At the core of our mission and vision is the 1095 Strong, quality every day philosophy. This commitment to ongoing education and quality improvement demonstrates survey readiness not only on the day of the survey but all 1,095 days of the accreditation term. A complete list of the AAAHC Policies and Procedures can be found within the Accreditation Handbook for Medicare Deemed Status.

Surveys tailored to your organization

AAAHC tailors your accreditation survey to the type, size, and range of services offered by your organization. AAAHC determines the length of the onsite visit and the number of surveyors based on your Application for Survey and supporting documents. These factors determine your survey fee.

We welcome questions regarding the scope of your survey or the estimated survey cost. Application fees are non-refundable.

Earn your accreditation term

AAAHC awards accreditation for three years when it concludes that the organization is in substantial compliance with the Standards, and when AAAHC has no reservations about the organization’s continuing commitment to provide high-quality patient care and services consistent with the Standards. Organizations may receive a three-year term with intracycle activities required for continued assessment of ongoing compliance with the Standards.

Post your public notice of survey

AAAHC reminds all organizations that the policy requires that a Notice of Accreditation Survey be posted prominently throughout the organization for (30) calendar days prior to the scheduled survey date(s), with the exception of random and discretionary surveys.

For Medicare Deemed Status surveys, the Notice must be posted immediately after the invoice packet containing a copy of the notice is received by the organization. The Notice must be posted at least until the end of the survey or for a minimum of 30 calendar days, even if that period extends beyond the end of the survey.

Understand a denial or revocation of accreditation

AAAHC denies accreditation to an organization when it concludes that the organization is not in substantial compliance with AAAHC Standards and/or policies and procedures.

AAAHC reserves the right to revoke or deny the accreditation of any organization at any time without prior notice. Your AAAHC account manager will help you navigate the requirements to remain in good standing.
