Outpatient Facility Drug Screen Coverage Criteria

Reimbursement policy for outpatient facility claims:

The health plan allows reimbursement for presumptive (CPT) and definitive (HCPCS Level II) drug screen testing when submitted on an outpatient facility claim unless provider, state, federal contracts and/or requirements indicate otherwise.

ALL of the following

The health plan considers CPT definitive drug screen testing codes to be always bundled and not eligible for reimbursement.
When HCPCS Level II definitive drug code G0659 is reported with G0480, G0481, G0482, or G0483, only G0659 will be eligible for reimbursement.

Definitive drug testing may be used to detect specific substances not identified by presumptive methods and to refine the accuracy of the presumptive test results.

Documentation and Authorization Requirements

Documentation Required

Documentation and Authorization Requirements

Provider documentation and the member's medical records must reflect that the test was properly ordered. For definitive testing that is confirmatory, the provider's documentation must support that the order was based on the result of the presumptive test. Services must also meet authorization and medical necessity guidelines appropriate to the procedure and diagnosis and the member's state of residence.

Record the clinical reason for ordering the test and link to the presumptive test result when definitive testing is confirmatory.
Ensure documentation supports medical necessity and any required authorizations per member state and plan.
Support all billed CPT/HCPCS codes with corresponding entries in the medical record or office notes.

Key Definitions

Definitive Drug Testing

PurposeDefinitive drug testing may be used to detect specific substances not identified by presumptive methods and to refine the accuracy of the presumptive test results.

Use caseTypically used to confirm or identify specific analytes when initial presumptive testing is inconclusive or identifies a target that requires confirmation.

DocumentationProvider documentation and member medical records should reflect that the definitive test was properly ordered; for confirmatory definitive testing, documentation should support that the order was based on the presumptive test result.

Presumptive Drug Screen Testing

DefinitionPresumptive testing refers to initial screening tests typically reported with CPT codes.

RoleServes as the initial screen to identify potential substance presence and may trigger definitive/confirmatory testing when indicated.

Reimbursement contextPresumptive (CPT) drug screen testing is allowed for reimbursement on outpatient facility claims subject to policy rules; CPT definitive codes are treated as bundled and not reimbursable.
