PAYMENT POLICIES FOR AMBULANCE RELATED SERVICES
Emergency Transport
Ambulance services are paid when the injury to the worker is so serious that use of any other method of transportation is contraindicated. Payment is based on the level of medically necessary services provided, not simply on the vehicle used.
Air ambulance transportation services, either by helicopter or fixed wing aircraft, will be paid only if:
- The worker‘s medical condition requires immediate and rapid ambulance transportation that could not have been provided by ground ambulance or
- The point of pickup is inaccessible by ground vehicle or
- Great distances or other obstacles are involved in getting the worker to the nearest place of proper treatment.
Proper Facilities
The insurer pays the provider for ambulance services to the nearest place of proper treatment. To be a place of proper treatment, the facility must be generally equipped to provide the needed medical care for the worker. A facility is not considered a place of proper treatment if no bed is available when inpatient medical services are required.
Multiple Patient Transportation
The insurer pays the appropriate base rate for each worker transported by the same
ambulance. When multiple workers are transported in the same ambulance, the mileage will be
prorated equally among all the workers transported. The provider must use HCPCS Modifier
GM (Multiple Patients on 1 Ambulance Trip) for the appropriate mileage billing codes. The
provider is responsible for prorating mileage billing codes based on the number of workers
transported on the single ambulance trip.
Nonemergency Transport
Nonemergency transportation by ambulance is appropriate if:
- The worker is bed-confined (see bed-confined criteria below), and it is documented that the worker‘s accepted medical condition is such that other methods of transportation are contraindicated or
- If the worker‘s accepted medical condition, regardless of bed confinement, is such that transportation by ambulance is medically required.
Bed-confined criteria:
- The worker is unable to get up from bed without assistance and
- The worker is unable to ambulate and
- The worker is unable to sit in a chair or wheelchair.
Nonemergency transportation may be provided on a scheduled (repetitive or nonrepetitive) or unscheduled basis.
- Scheduled, nonemergency transportation may be repetitive, for example, services regularly provided for diagnosis or treatment of the worker‘s accepted medical condition or nonrepetitive, for example, single time need
- Unscheduled services generally pertain to nonemergency transportation for medically necessary services
Workers may not arrange nonemergency ambulance transportation. Only medical providers may arrange for nonemergency ambulance transportation.
The insurer reserves the right to perform a post audit on any nonemergency ambulance transportation billing to ensure medical necessity requirements are met.
Arrival of Multiple Providers
When multiple providers respond to a call for services, only the provider that furnishes the
transport of the worker(s) is eligible to be paid for the services provided. No payment is made
to the other
provider(s).
Mileage
The insurer pays for mileage (ground and/or air) based on loaded miles only, for example, from the pickup of the worker(s) to their arrival at the destination. The destination is defined as the nearest place of proper treatment.
