Physicians, nonphysician practitioners and their organisations must report to the Medicare contractor within 30 days a change of ownership, any adverse legal action, and a change, addition or deletion of a practice location, and all other enrollment changes within 90 days. All other providers and suppliers (other than IDTFs under 410.33(g)(2), DMEPOS suppliers under 424.57(c)(2) and MDPP suppliers under 424.205(d)) must report within 30 days a change of ownership or control including changes of authorized or delegated officials, an adverse legal action, and a change, addition or deletion of a practice location, and all other changes within 90 days; an air ambulance supplier must report within 30 days any revocation or suspension of a Federal or State licence or certification including FAA pilot, medical and airworthiness certifications. Failure to report is a revocation ground and, for physicians and practitioners, an overpayment is assessed back to the date of the adverse action or location change.
