What Is Modifier QL?

Modifier QL is a HCPCS ambulance modifier used when an ambulance has been dispatched for a patient, but the patient is pronounced dead before being transported.

Medicare has specific payment rules for these situations because an ambulance provider or supplier may have already committed resources and responded to the call even though transportation was ultimately not performed.

The exact payment treatment depends on when the patient was pronounced dead in relation to the ambulance dispatch, response, and potential transport.

QL should not be treated as a general modifier for unsuccessful ambulance transports or situations in which transportation simply did not occur.

When to Use Modifier QL

Ambulance Was Called: An ambulance was legitimately requested and dispatched for the beneficiary.

Death Occurred After the Call: The patient was pronounced dead after the ambulance had already been called.

No Patient Transport Occurred: The patient was not transported because death was pronounced before transportation could take place.

Ground Ambulance Was Dispatched: QL can identify qualifying circumstances involving a ground ambulance response when the patient is pronounced dead before transport.

Air Ambulance Was Dispatched: QL can also apply to qualifying air ambulance circumstances when the aircraft was dispatched and applicable requirements are satisfied.

When NOT to Use Modifier QL

Death Was Known Before Dispatch: Do not use QL when the ambulance service knew the patient had already been pronounced dead before the ambulance was called or dispatched.

The Patient Was Transported: QL describes circumstances in which the patient is pronounced dead before transport. Different rules apply when a patient dies during transportation.

No Ambulance Was Dispatched: A call that does not result in an actual ambulance dispatch does not support QL.

The Call Was Canceled for Another Reason: QL is not a general modifier for canceled ambulance calls, refusals of transport, or other nontransport situations.

Documentation Does Not Establish the Timing: The record should clearly establish that the pronouncement occurred after the ambulance was called and before transport.

Billing Example

An ambulance is dispatched in response to an emergency call for a Medicare beneficiary.

Before the ambulance can transport the patient, an individual authorized to pronounce death determines that the patient has died.

Because the ambulance was called before the patient was pronounced dead and no transport occurred, Modifier QL may be reported with the applicable ambulance service when the remaining billing and payment requirements are satisfied.

Documentation Requirements

Dispatch Information: Document when the ambulance was requested and dispatched.

Pronouncement of Death: Record when the patient was pronounced dead and identify the circumstances surrounding the pronouncement.

Authorized Individual: Documentation should support that the pronouncement was made by an individual authorized under applicable law to pronounce death.

Response Information: Record the ambulance unit's response and relevant arrival information.

No Transport: Clearly document that the beneficiary was not loaded and transported.

Air Ambulance Details: For qualifying air ambulance situations, documentation should establish that the aircraft actually took off and that the dispatcher did not receive the pronouncement in sufficient time to abort the flight when those requirements apply.

Billing and Claim Considerations

Modifier QL has special Medicare ambulance payment rules because no completed transport occurs.

When a qualifying ground ambulance has been dispatched and the beneficiary is pronounced dead after the ambulance was called but before transport, payment may be available for the applicable base ambulance service. Mileage is not payable because the beneficiary was not transported.

For a qualifying air ambulance, payment may be available for the applicable fixed-wing or rotary-wing base rate when the aircraft actually took off before the beneficiary was pronounced dead or before the crew could reasonably be notified to abort the response. Mileage is not payable when the beneficiary was never loaded.

QL replaces the normal ambulance origin-and-destination modifier in applicable institutional billing circumstances involving a beneficiary pronounced dead after the ambulance was called.

Other ambulance modifiers may still be required depending on how the service was furnished and the type of claim.

Modifier QL and QM/QN

QL describes why the ambulance service did not result in transportation, while QM and QN describe how the ambulance service was furnished.

Modifier QM: Ambulance service provided under arrangement by a provider of services.

Modifier QN: Ambulance service furnished directly by a provider of services.

For applicable institutional ambulance claims involving QL, QM or QN may also be required to identify whether the ambulance service was furnished directly or under arrangement.

These modifiers perform different functions and should not be treated as substitutes for one another.

Ground vs. Air Ambulance Considerations

The QL circumstances can involve either ground or air ambulance services, but the payment requirements differ.

For ground ambulance services, payment may generally be based on the applicable base service when the qualifying requirements are satisfied.

Air ambulance claims require additional consideration because the aircraft must have actually taken off for the qualifying response. If the dispatcher learns of the patient's death with enough time to prevent the aircraft from taking off, the circumstances do not support payment under the special air ambulance rule.

Neither ground nor air ambulance mileage is payable when the patient was never transported.

Common Billing Mistakes

Using QL for Any Nontransport: QL is specifically associated with a patient pronounced dead after the ambulance was called.

Reporting Mileage Without Transport: Mileage should not be reported as though a patient transport occurred when the beneficiary was never loaded and transported.

Using a Standard Origin/Destination Modifier Incorrectly: QL has specific reporting rules in applicable ambulance billing circumstances.

Missing QM or QN When Required: Applicable institutional ambulance claims may require QM or QN in addition to QL.

Insufficient Timing Documentation: The record should establish that the ambulance was called before the patient was pronounced dead.

Applying Ground Ambulance Rules to Air Ambulance Claims: Air ambulance payment has additional requirements, including whether the aircraft actually took off.

Common Denial Reasons

Death Occurred Before the Ambulance Was Called: The circumstances do not meet the purpose of QL.

Dispatch Is Not Supported: Documentation does not establish that an ambulance was actually dispatched.

Incorrect Ambulance Code: The HCPCS ambulance service reported does not correspond to the documented response.

Unsupported Air Ambulance Response: Documentation does not establish the required aircraft response for payment.

Improper Mileage Billing: Mileage is reported even though the beneficiary was never transported.

Incomplete Documentation: The claim or medical record does not clearly establish dispatch, pronouncement, response, and nontransport circumstances.

Frequently Asked Questions

Can Modifier QL be used when an ambulance arrives but the patient is pronounced dead before transport?
Yes. QL can apply when the ambulance was called before the patient was pronounced dead and the beneficiary was not subsequently transported, provided the applicable ambulance billing requirements are satisfied.

Is ambulance mileage payable when Modifier QL is reported?
Generally, no. Because the beneficiary is not transported, there are no loaded ambulance miles to report. Payment may instead be based on the applicable ambulance base service when the qualifying requirements are met.
