Non-Emergency Ground Ambulance (BSC10.02)
Blue Shield of California updated its Non-emergency Ground Ambulance medical policy (BSC10.02), effective November 1, 2026. The updated policy statement says non-ambulance transportation must be unsuitable due to patient safety concerns or medical contraindications, the destination must be the nearest appropriate healthcare facility or the individual's home from a healthcare facility after covered services, and a Provider Certification Statement is required, and criterion E now reads that non-emergency ground ambulance was used to transport the patient. Appendix A of the policy compares the earlier and updated policy statements.

Navigating the Miles How to Bill for Ground Ambulance Mileage
New policy clarifies ground ambulance mileage billing procedures, specifying that A0425 should be billed for one-way mileage from pickup to destination.

Excellus BlueCross BlueShield · Effective Mar 19, 2026Medium impact
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 and Medical Transport Services
Blue Cross Blue Shield of Mississippi covers ground emergency transport when the transport complies with applicable laws and licensing, has the necessary equipment, any other form of transportation would be medically contraindicated, and the patient is taken to the nearest hospital with appropriate facilities. Non-emergency ground transport between health care facilities requires prior authorization and must go to the nearest provider with the required capabilities, and non-emergency ground transport of bed-confined patients to a lower level of care requires that the patient meets the bed-confinement criteria and that the trip report describes symptoms, physical findings and monitoring. All air ambulance services require authorization, while transport to or from a physician's office, transport for routine renal dialysis, and transport by regularly scheduled commercial carrier are not covered.
