Ambulance: Land/Ground 10.01.07
Excellus policy 10.01.07 considers emergency land ambulance transport medically appropriate when the New York State mandate does not apply and all of the following are met: the ambulance service holds a certificate under the NYS Public Health Law, the ambulance has the necessary patient-care equipment and supplies, any other form of transportation would be medically contraindicated, and the patient is taken to the nearest hospital with appropriate facilities for the illness or injury. Non-emergent ambulance medical transport is medically appropriate under the same certification, equipment and contraindication criteria when the specialized service is at the nearest facility with the required capabilities and one of four listed indications applies, and elective or convenience transport is considered not medically necessary. The 03/19/26 annual review removed the criteria for urgent ambulance transportation and the criteria addressing cost effectiveness.

Ambulance Services
Air or water ambulance services to the nearest facility capable of providing appropriate treatment are medically necessary with documentation of ANY of the following: the emergency, accident or acute illness occurs in an area inaccessible by ground vehicles, or transport cannot be safely provided by ground ambulance due to great distances, prolonged transport time or other obstacles that would be harmful to the individual's medical condition. Ground ambulance services are medically necessary with documentation of ANY of the following: the individual's medical condition requires transport from the site of an emergency, accident or acute illness to the nearest facility capable of providing appropriate treatment, or interfacility transport for admission is needed when the transferring facility is unable to provide the level of service required. Transport provided primarily for the convenience of the individual, family or physician, transport to a physician's office, physical therapy, diagnostic or therapeutic services, home or other non-emergent outpatient services, and transport that would be otherwise appropriate in a stretcher van or wheelchair van are a benefit plan exclusion and not eligible for coverage.

Independence Blue Cross MA12.002e policy reaffirms existing coverage criteria for ground and sea ambulance transport services (emergency and nonemergency) for Medicare Advantage members, effective 09/22/2025. The policy clarifies medical necessity requirements, coverage for deceased individuals, paramedic intercept services, inter-facility transfers, and specifies eligible HCPCS codes. This is a policy review/reissuance rather than a substantive change, maintaining alignment with Medicare coverage guidelines.
