Effective February 1, 2027, Sentara Health Plans will require prior authorization for nine specific medical codes related to injectable/therapeutic joint procedures and ambulance services for all Commercial products in Virginia. Additionally, DMAS has already restricted coverage (effective October 13, 2026) of gender-affirming procedures for Medicaid and CHIP youth, though this does not change billing requirements—only coverage eligibility.
Excellus policy 11.01.06 considers air ambulance transport medically appropriate only to the nearest facility that can provide the appropriate care, when the individual's condition required immediate and rapid transport to minimize risk of death or deterioration that could not have been provided by land ambulance, and either the pick-up point is inaccessible by land vehicle or great distances or other obstacles would affect transport to the nearest appropriate hospital by ground. Hospital-to-hospital air transport is medically appropriate when the transfer is to a higher level of care hospital for medical services unavailable at the transferring facility and ground ambulance would endanger the individual's health, and it is considered not medically appropriate for transport to a non-acute care facility or for non-emergent transport of a stabilized individual. The 03/19/26 annual review removed emergent or urgent conditions from the policy statements.
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.
