CMS Pub. 100-04, ch. 1, § 10.1.5.3
Ambulance Services Submitted to Carriers
Jurisdiction of the claim is based on whether only one ambulance vehicle or multiple
vehicles were used.
A. One Ambulance Vehicle Used
If only one vehicle is used to transport the patient from the point of initial pickup to the
final destination, jurisdiction is with the carrier serving the point of origin, i.e., home
station of the vehicle. This carrier has qualification information on the ambulance
supplier and in most cases all other pertinent details necessary to adjudicate a claim.
EXAMPLE: A patient is picked up at the Johns Hopkins Hospital in Baltimore,
Maryland and transported to his home in West Virginia by an ambulance dispatched from
the area of the patient’s home. The carrier serving the point of origin of the ambulance,
Nationwide Mutual Insurance Company, Part B carrier for the State of West Virginia, has
jurisdiction of any claim filed. In this case Nationwide should have all the data necessary
to make proper payment, i.e., certification of the ambulance company, price information
and data pertaining to the nearest appropriate company, price information and data
pertaining to the nearest appropriate facility. Had an ambulance whose home station was
in Baltimore been used, the carrier servicing Baltimore, Maryland would have had
jurisdiction. The Baltimore carrier would then have had to obtain data concerning the
nearest appropriate facility to the patient’s home from Nationwide
B. More Than One Vehicle Used
If more than one vehicle is used in transporting the patient to their destination,
jurisdiction of the claim lies with:
• The carrier serving the home base of the ambulance taking the patient on the first
leg of the trip, on a trip to a distant institution more remote than the nearest
appropriate facility; or
• The carrier serving the home base of the ambulance taking the patient on the final
leg of the trip home, on a trip from an institution more remote than the nearest
appropriate facility.
• If there is no claim for the final leg of the trip, the carrier serving the patient’s
home area handles any resulting claims or disallowance actions.
EXAMPLE: A patient is transported by ambulance from a hospital in Miami Beach,
Florida to Miami International Airport and from there by air ambulance to LaGuardia
Airport in Queens, New York City. At the airport he is picked up by an ambulance (based
in Yonkers, New York) and taken to his home in Yonkers, New York. The carrier that
handles the adjudication is the carrier whose area of responsibility includes Yonkers,
New York, since partial reimbursement is based upon the nearest appropriate facility to
his residence when he is being returned home from a distant institution.
In rules A and B above, the principle followed is that the carrier having the information
to determine the “nearest appropriate facility” is the one to adjudicate the claim. In any
event, before any partial reimbursement can be made, the carriers as designated in rules
A and B, must have all the information concerning the patient’s transportation, from
initial pickup to final destination.
