Effective July 14, 2009, physician offices that perform surgical or invasive procedures using more than mild sedation must be accredited by one of three accrediting agencies. The NYSDOH collects OBS practice site accreditation data from each of the accrediting agencies monthly. The OBS practice accreditation site data is used to keep an accurate list of accredited OBS practice sites for patient safety and regulatory efforts.
