Documentation and Billing Actions for Providers

Documentation Required

Medical necessity documentation — what to record

Document clinical rationale and supporting evidence in the medical record at the time of service. Include the patient’s signs, symptoms, diagnosis, relevant history, risk factors (e.g., prior overdose, suspected diversion, changes in medication adherence), and how test results will affect clinical management. Retain copies of laboratory reports and chain-of-custody documentation when applicable. Medical necessity must be evident for any drug testing beyond routine or screening use; units exceeding quantity limits may be subject to review.

Include indication/clinical question prompting the test (e.g., suspected toxicity, adherence check, confirmation of unexpected screen).
Document relevant medications and dosing, recent changes in therapy, and any prior drug test results.
Note clinical decision impact — how a positive or negative result will change treatment, monitoring, or safety actions.
Attach or reference lab reports, chain-of-custody forms, and any confirmatory testing performed.

Billing Rule

Quantity limit enforcement

Bill up to one definitive and one presumptive drug test per date of service, per member. Presumptive testing is optional and is not required before performing a definitive test. Any presumptive or definitive units beyond these limits may be denied or subject to medical necessity review.

Reimbursement limited to: one definitive test and one presumptive test per member per date of service.
Presumptive testing is not a prerequisite for definitive testing; providers may bill definitive tests without a prior presumptive test.
Ensure documentation justifies any claims exceeding these quantity limits to support medical necessity.

Definitions

Presumptive testing (definition and usage)

DefinitionPresumptive testing (drug screening) is used to determine the presence or absence of drugs or a drug class; results are expressed as negative or positive and the methodology used is considered when coding.

Reporting frequencyThe presumptive test is a single per-member service and should only be reported once per date of service regardless of number of drug classes or results.

Role in careUsed as an initial screening tool to detect possible drug use before any confirmatory testing is performed.

Definitive testing (definition and reporting guidance)

DefinitionDefinitive (confirmation) testing identifies specific medications, illicit substances, and metabolites and reports concentrations (qualitative or quantitative).

Coding guidanceConsistent with CMS, CPT codes 80320–80377 for definitive testing are non-reimbursable; report HCPCS G0480–G0483 or G0659 instead.

Medical necessity & documentationDocumentation must support medical necessity and the clinical indicators that led to ordering the definitive test; units exceeding quantity guidance may be subject to review.

Specimen validity testing (definition and reimbursement)

DefinitionSpecimen validity testing is quality control of the collection process to confirm specimen integrity (e.g., adulteration, dilution, substitution).

Reimbursement stanceSpecimen validity testing is included in presumptive and definitive drug testing CPT and HCPCS code descriptions and is not separately reimbursable per NCCI alignment.

RationaleConsidered an integral part of specimen collection and quality control rather than a standalone billable service.
