The OIG has issued a report entitled "South Florida Durable Medical Equipment Suppliers: Results of Appeals." The OIG followed up on a previous review that had led to the revocation of Medicare billing privileges for 491 suppliers that failed to meet Medicare supplier standards. The OIG found that nearly half of the revoked suppliers appealed the revocations, and billing privileges were restored for 91% of these suppliers. The OIG found that two-thirds of the suppliers whose billing privileges were reinstated subsequently had their privileges revoked again or inactivated, and some individuals connected to reinstated suppliers have been indicted. The OIG recommended that CMS strengthen the appeal process by developing criteria regarding the types of evidence required for hearing officers to reinstate suppliers' billing privileges; CMS agreed to consider establishing such guidelines.
