Update on HHS Office of the Inspector General Reports on Ambulance Services

The HHS Office of the Inspector General (OIG) released an update to the Work Plan as the year comes to a close.  There are no new projects specific to ambulance services, but the update does provide a summary of three projects that have been completed or are in progress.

• Medicare Part B Payments for Ambulance Services Subject to Part A Skilled Nursing Facility Consolidated Billing Requirements (expected release 2019). In this work, the OIG  seeking to determine whether ambulance services paid by Medicare Part B were subject to Part A SNF consolidated billing requirements. The OIG will also assess the effectiveness of edits in CMS’s Common Working File to prevent and detect Part B overpayments for ambulance transportation subject to consolidated billing. Prior OIG reports have identified high error rates and significant overpayments for services subject to SNF consolidated billing.
• Ambulance Services – Supplier Compliance with Payment Requirements (partially completed; remainder expected release 2019). Prior OIG work has found that Medicare made inappropriate payments for advanced life support emergency transports. The OIG seeks to determine whether Medicare payments for ambulance services were made in accordance with Medicare requirements. 

The first report of this project found that Medicare made improper payments of $8.7 million to providers for nonemergency ambulance transports to destinations not covered by Medicare, including the identified ground mileage associated with the transports.  The report identified that the majority of the improperly billed claim lines (59 percent) were for transports to diagnostic or therapeutic sites, other than a physician’s office or a hospital, that did not originate from SNFs.

In this report, the OIG recommended that the CMS: (1) direct the Medicare contractors to recover the portion of the $8.7 million in improper payments made to providers for claim lines that are within the claim-reopening period; (2) for the remaining portion of the $8.7 million, which is outside of the Medicare reopening and recovery periods, instruct the Medicare contractors to notify providers of potential improper payments so that those providers can exercise reasonable diligence to investigate and return any identified similar improper payments, and identify and track any returned improper payments; (3) direct the Medicare contractors to review claim lines for nonemergency ambulance transports to destinations not covered by Medicare after the audit period and recover any improper payments identified; and (4) require the Medicare contractors to implement nation-wide prepayment edits to ensure that payments to providers for nonemergency ambulance transports comply with Federal requirements.

• The third report is linked to a case study of the closure of the Rosebud Hospital Emergency Department. Rosebud is an Indian Health Service (IHS) hospital that discontinued emergency services. The closure of the Rosebud emergency department (ED) followed a notice of intent by the CMS to terminate Rosebud Hospital from the Medicare program. Representatives of the Rosebud Sioux Tribe raised concerns to OIG about the Rosebud ED closure and linked that closure to several patient deaths that occurred during ambulance transports to other facilities when emergency care was unavailable locally. In response to these concerns, the OIG seeks to examine factors considered and procedures involved in IHS’s decisions to close and later reopen the Rosebud ED. The OIG will also assess IHS’s management, coordination, and communication related to the closure and will identify lessons learned that IHS could apply to similar situations in the future.  The report was expected to be published in 2018, but has not as of this date. 

The AAA continues to monitor the OIG work plan and engage as appropriate with key officials.  Our goal is to provide educational background to address any misunderstandings or incorrect assumptions that may exist.
