Air Versus Ground Transport Time Advantage

General thresholdAir ambulance transport is generally projected to be at least 30 minutes shorter than ground ambulance transport.

Applies whenThe time-and-distance test is used when ground transport would threaten survival or seriously endanger the patient's health.

Transport comparisonThe comparison is based on the total estimated transportation time from the pickup site or originating facility to the receiving facility.

ALS2 Medication Administration Pathway

Service levelALS2 includes medically necessary ground ambulance transportation and medically necessary supplies and services.

Medication countThe medication pathway requires at least 3 separate administrations of 1 or more medications.

Documentation, Coverage, and Denial Risks

Documentation Required

Document Medical Necessity and Transport Circumstances

Document the patient’s condition and the circumstances requiring ambulance transport, including why other transportation is medically contraindicated, the emergency or non-emergency status, and the clinical reason for the selected ground or air level of service. Record compliance with applicable laws, licenses, permits, required equipment and supplies, the patient’s condition and interventions, and the nearest appropriate receiving facility or permitted exception.

For emergency ground transport, document that the patient could not safely use another form of transportation and was taken to the nearest hospital with appropriate facilities, subject to documented exceptions such as divert, unavailable beds or accepting physician, transplant-facility requirements, or network considerations.
For emergency air transport, document critical condition or unstable vital, respiratory, or cardiac status and the qualifying condition; for scene pickup, also document inaccessible ground access, adverse road or weather conditions, or that ground transport threatened survival or seriously endangered health.
For facility-to-facility air transport, document that the originating facility could not provide the required acute intervention, the receiving facility’s equivalent or higher acuity, and why ground transport endangered the patient; a projected air-time advantage of at least 30 minutes generally satisfies the time-and-distance consideration.
For non-emergency transport, document inpatient status or the need for trained attendants to monitor or treat the patient, inability to use other transportation, unavailable services at the originating facility, and that the receiving facility is the nearest with required capabilities. Convenience, preference, or long-distance travel alone does not establish medical necessity.

Policy Background

Ambulance and medical transport services use specially designed and equipped vehicles to transport ill or injured patients by ground, air, or sea for emergency and non-emergency care. Coverage focuses on whether the patient’s condition requires ambulance-level monitoring, treatment, or rapid transport because other transportation would be unsafe or medically contraindicated.

Key Terms

Advanced Cardiac Life Support (ACLS)

PurposeA constellation of clinical interventions for the urgent treatment of cardiac arrest, stroke, and other life-threatening non-traumatic emergencies.

FoundationACLS augments basic life support efforts, including cardiopulmonary resuscitation (CPR).

Examples of interventionsInterventions may include airway management, vein assessment, ECG/EKG interpretation, emergency pharmacology, and early defibrillation with automated external defibrillators as needed.

Advanced Life Support, Level 1 (ALS1)

TransportWhen medically necessary, ALS1 includes transportation by a ground ambulance vehicle.

Assessment or interventionALS1 includes an ALS assessment or at least one ALS intervention.

Transport based only on long distances between the transferring and receiving facilities is not medically necessary. Consideration may be given to allowing the member to remain within a specific hospital network.

Permitted administrationMedications must be administered by intravenous push/bolus or continuous infusion; crystalloid fluids are excluded.

Documentation Required

Document Level of Care and Interventions

Document the transport level, medically necessary supplies and equipment, interventions, medications, and qualified personnel that supported the billed level of care. The record should support the distinction among BLS, ALS1, ALS2, and SCT services.

Identify the transport level: BLS, ALS1, ALS2, or Specialty Care Transport (SCT), and document staffing consistent with state and local requirements.
For BLS, document medically necessary supplies and services and qualified EMT-Basic staffing; relevant interventions may include airway assessment and management, positive-pressure ventilation, over-the-counter pharmacologic interventions, and fracture stabilization.
For ALS1, document an ALS assessment or at least one ALS intervention beyond the EMT-Basic scope. For ALS2, document at least three separate intravenous push/bolus or continuous-infusion medication administrations, excluding crystalloid fluids, or at least one qualifying procedure such as defibrillation/cardioversion, endotracheal intubation, central venous line, cardiac pacing, chest decompression, surgical airway, or intraosseous line.
For SCT, document why ongoing care beyond the EMT-Paramedic scope was required and the involvement of appropriately specialized professionals, such as emergency or critical-care nursing, emergency medicine, respiratory care, or cardiovascular care.
Record the patient assessment, monitoring, treatments, medications, equipment and supplies used during transport; devices and supplies are integral to the ambulance service and are not separately payable.

Billing Rule

Verify Member-Specific Coverage

Apply the member’s specific benefit plan and policy terms before determining coverage or reimbursement. Medical-necessity criteria in this policy do not replace the member-specific benefit documentation or other applicable contractual terms and conditions.

Verify eligibility, benefit limitations, exclusions, authorization requirements, and applicable network provisions for the member.
Apply the written coverage position in this policy together with the member’s benefit plan, legal requirements, and other applicable policies or guidelines.

Denial Risk

Criteria or Medical Necessity Not Established

Transport is not medically necessary when the applicable emergency or non-emergency criteria are not met. Non-medical transport, including medical vans or commercial transportation, is also excluded under the stated indications.

Non-emergency transport primarily for the convenience of the patient, family or caregivers, physician, or transferring facility is not medically necessary.
Transfers from a home or covered skilled nursing facility to a physician’s office or another facility for outpatient treatment, procedures, or tests are not covered under these indications.

Denial Risk

Air Transport Not Justified Over Ground

Air transport is not medically necessary when ground transportation is available and the time required by ground would not endanger the patient’s life or health. Document the clinical and time-distance basis supporting air transport when it is billed.

A projected air-transport time at least 30 minutes shorter than ground generally supports the policy’s time-and-distance consideration, but the patient’s condition and risk must also meet the applicable air-transport criteria.

Denial Risk

Inappropriate or Non-Nearest Destination

Transport may be denied when the destination is unsuitable or is not the closest facility capable of providing the required level of care. Transport from a capable hospital to another hospital primarily for convenience, preference, or provider choice is also not medically necessary.

The destination must generally be an acute care hospital with appropriate facilities for the condition, or the nearest equivalent or higher-acuity facility when applicable.
Document any permitted exception, such as divert status, lack of available beds or accepting physician, inability of an air ambulance to land, approved transplant-facility destination, or a specific hospital-network consideration.

Denial Risk

Excluded Transport Situations

The policy does not cover transportation of a patient pronounced dead at the scene, transportation related to search and rescue operations, or transfers from a home or covered skilled nursing facility to outpatient destinations. These situations remain excluded even if transportation is requested or arranged by a provider.

Deceased-patient transport is excluded when the patient was pronounced dead at the scene.
Search-and-rescue transportation is excluded.
Home or covered SNF transfers to physician offices or other facilities for outpatient treatment, procedures, or testing are excluded.
Benefits are not provided for medical transport to nursing facilities, physician offices, or the patient’s home.

Billing Rule

Life-Support Equipment Must Be Used

When a life-support ambulance is used, the life-support equipment must also be used for the service to be covered. Document the equipment used and its relationship to the patient’s medically necessary care.

A life-support ambulance alone does not establish coverage if the associated life-support equipment was not used.
Reusable and disposable devices or supplies are integral to the ambulance and medical transport service and are not separately payable.

Note

Confirm Line-of-Business Applicability

Confirm that this policy applies to the member’s line of business before using it to determine coverage. The policy may not apply to every Bluecross Idaho product or group arrangement.

Potential exceptions include the Federal Employee Program, Medicare Supplement, Medicare Advantage, Medicaid, and certain self-insured groups.
Apply the governing benefit documents and applicable product-specific policies when this policy does not control.

Billing Rule

Code Listing Does Not Guarantee Payment

The listed codes and coding guidance are for general reference only and may not be all-inclusive. Code inclusion does not guarantee member coverage or provider reimbursement, and code exclusion does not establish that coverage or reimbursement is unavailable.

Determine payment using the member-specific benefit plan documentation, this policy’s written coverage position, legal requirements, and other applicable policies and guidelines.
Do not infer a right to payment solely from reporting a code.

Intervention scopeAn ALS intervention is a procedure beyond the scope of an EMT-Basic.

Advanced Life Support, Level 2 (ALS2)

TransportALS2 includes transportation by a ground ambulance vehicle and medically necessary supplies and services.

Medication pathwayQualification may require at least 3 separate administrations of 1 or more medications by intravenous push/bolus or continuous infusion, excluding crystalloid fluids.

Alternative procedure pathwayAlternatively, qualification requires at least 1 specified procedure: defibrillation/cardioversion, endotracheal intubation, central venous line, cardiac pacing, chest decompression, surgical airway, or intraosseous line.

Appropriate Facilities

General standardAn appropriate facility is generally equipped and staffed to provide the necessary care for the individual's health condition.

Acute care hospital requirementFor an acute care hospital, an appropriate physician or physician specialist must be available.

Required capabilityThe available physician or specialist must be able to provide the care necessary to treat the individual's condition.

Examples of contraindicationsExamples include bed confinement, need for continuous supervision, physical restraint status, or dependence on enabling machines or devices.

Available levelsTransport may be provided at either the basic life support (BLS) or advanced life support (ALS) level of care.

Nonemergent Condition

Medical needA nonemergent condition requires medical attention that may be provided or directed by a physician shortly after occurrence.

Severity limitationThe condition is not severe enough to meet the policy's definition of emergency.

TimingMedical attention may be provided or directed shortly after the condition occurs.

Rotary-Wing Air Ambulance

Aircraft typeA rotary-wing air ambulance is a helicopter.

Access advantageIt can provide rapid, direct access to the scene of an accident or illness.

Typical useIt is generally reserved for short-range transports or situations in which ground ambulance transport would result in unacceptable delays.

Specialty Care Transport (SCT)

Transport settingSpecialty Care Transport (SCT) is interfacility transportation of a critically ill or injured individual.

Care requirementThe individual's condition requires ongoing medical care during transport.

Level of careThe required care is beyond the scope of an Emergency Medical Technician-Paramedic.

Qualified specialty professionalsCare is furnished by one or more professionals in an appropriate specialty, such as emergency or critical care nursing, emergency medicine, respiratory care, or cardiovascular care.
