Evaluating Your Ambulance Transportation Medical Billing Procedure

Ambulance Transportation Medical billing has been under the lens of Medicare for a very long time due to the fabrication of medical charges and unreasonable billing rates for the patients during an emergency. In September 2015, a report was released by the Office of Inspector General (OIG) after studying Medicare Part B Ambulance claims. The report clearly stated that almost 20 percent of ambulance providers have inappropriate methods and questionable billing for ambulance transport.

Medicare is worried if the gaping holes in the system can be identified and used to exploit the opportunity. The OIG identified few key points,

  • Ambulance Transport for beneficiaries that didn’t receive any Medicare at the point of origin and destination.
  • Mileage report has been towards the higher part for the urban areas.
  • Transport levels for the destinations that aren’t covered.

Though each of the points remains to be evaluated based on the patient health, transport facilities available in the region, and also demand for specialized care in case of emergency.

Emergency vehicle administrations are secured under Medicare Part B when outfitted to a Medicare recipient under the conditions recorded beneath. Real transportation of the recipient happens. Recipient transported to a suitable destination.

Transportation by Ambulance vehicle must be therapeutically important, i.e., the recipient’s medicinal condition is with the end goal that different types of transportation are restoratively contraindicated. Ambulance Transportation supplier/provider meets all pertinent vehicles, staffing, charging, and revealing prerequisites. Transportation isn’t viewed as a major aspect of a Part An administration.

Ambulance billing companies across the nation need to evaluate their billing procedures before they can control the billing cycles. Below we give you an overview of Ambulance Transportation Billing,
