Medicare Paid Twice for Ambulance Services Subject to Skilled Nursing Facility Consolidated Billing Requirements

Prior OIG reviews identified significant Medicare Part B overpayments, including those to ambulance suppliers, for services they provided to Medicare beneficiaries during skilled nursing facility (SNF) stays covered under Medicare Part A. The Centers for Medicare & Medicaid Services (CMS) generally concurred with recommendations in these reports and implemented them. However, our analysis of recent claim data indicated that overpayments for ambulance transportation might still be occurring.
