Payment policy: Arrival of multiple providers
Payment limits
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, and
- No payment is made to the other provider(s).
Payment policy: Emergency air ambulance transport
Payment limits
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 couldn’t 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.
Payment policy: Multiple patient transportation
How these services are paid
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.
Requirements for billing
The provider is responsible for prorating mileage billing codes based on the number of workers transported on the single ambulance trip.
The provider must use HCPCS code modifier –GM (Multiple patients on one ambulance trip) for the appropriate mileage billing codes.
Payment policy: Nonemergency transport
Who may arrange for these services
Only medical providers may arrange for nonemergency ambulance transportation.
Note: Workers may not arrange nonemergency ambulance transportation.
Medical necessity requirements
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.
Note: Bed confined criteria are that the worker is:- Unable to get up from bed without assistance, and
- Unable to ambulate, and
- 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.
Note: The insurer reserves the right to perform a post audit on any nonemergency ambulance transportation billing to ensure medical necessity requirements are met.
Payment policy: Proper facilities
What makes a facility a 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 isn’t considered a place of proper treatment if no bed is available when inpatient medical services are required.
Payment limits
The insurer pays the provider for ambulance services to the nearest place of proper treatment.
