TL;DR

G0480 is a Level II code from the G section (procedures and professional services, temporary), in use since 2016: "Drug test(s), definitive, utilizing (1) drug identification methods able to identify individual drugs and distinguish between structural isomers (but not necessarily stereoisomers), including, but not limited to gc/ms (any type, single or tandem) and lc/ms (any type, single or tandem and excluding immunoassays (e.g., ia, eia, elisa, emit, fpia) and enzymatic methods (e.g., alcohol dehydrogenase)), (2) stable isotope or other universally recognized internal standards in all samples (e.g., to control for matrix effects, interferences and variations in signal strength), and (3) method or drug-specific calibration and matrix-matched quality control material (e.g., to control for instrument variations and mass spectral drift); qualitative or quantitative, all sources, includes specimen validity testing, per day; 1-7 drug class(es), including metabolite(s) if performed". The 2026 Q4 clinical laboratory fee schedule pays G0480 $114.43 (national limitation amount). MUE limits for G0480: practitioner 1 (MAI 2, Code Descriptor / CPT Instruction); hospital outpatient 1 (MAI 2, Code Descriptor / CPT Instruction). In the NCCI PTP files v323r0 G0480 appears in 17 practitioner pairs as column 2 and 82 as column 1 (most often with 0007U, 0011U, 0051U), and in 17 hospital outpatient pairs as column 2 and 82 as column 1. 7 active LCDs and 7 billing and coding articles list G0480 across 26 states plus DC and 2 territories: L34645 (Urine Drug Testing), L35006 (Controlled Substance Monitoring and Drugs of Abuse Testing), A54799, A55001. OPPS status indicator Q4: Conditionally packaged laboratory services. HCPCS record: BETOS T1H (lab tests - other (non-Medicare fee schedule)); pricing indicator 21; type of service 5 (diagnostic laboratory). 4 other active codes open with "Drug test"; related codes: G0481, G0659, G0482, G0483.

G0480 descriptor and code status

The October 2026 HCPCS Level II file describes G0480 as “Drug test(s), definitive, utilizing (1) drug identification methods able to identify individual drugs and distinguish between structural isomers (but not necessarily stereoisomers), including, but not limited to gc/ms (any type, single or tandem) and lc/ms (any type, single or tandem and excluding immunoassays (e.g., ia, eia, elisa, emit, fpia) and enzymatic methods (e.g., alcohol dehydrogenase)), (2) stable isotope or other universally recognized internal standards in all samples (e.g., to control for matrix effects, interferences and variations in signal strength), and (3) method or drug-specific calibration and matrix-matched quality control material (e.g., to control for instrument variations and mass spectral drift); qualitative or quantitative, all sources, includes specimen validity testing, per day; 1-7 drug class(es), including metabolite(s) if performed”. It sits in the G section (procedures and professional services, temporary), listed with the other G codes. Although searches often call it the "G0480 CPT code", G0480 is a HCPCS Level II code maintained by CMS, not an AMA CPT code; both go in the same procedure-code field on the claim.

Medicare payment for G0480

The 2026 Q4 clinical laboratory fee schedule pays G0480 $114.43 (national limitation amount). The amounts below are national figures from the October 2026 CMS files; the contractor applies the locality, rural or state adjustment and the beneficiary's cost sharing.

Physician fee schedule (RVU26D)

Status X: statutory exclusion: not a physician service under the fee schedule. Global period XXX (global surgery concept does not apply); PC/TC indicator 9 (professional/technical concept does not apply).

Clinical Laboratory Fee Schedule (26CLABQ4)

G0480 is paid at $114.43 (national limitation amount). Laboratory fee schedule payments carry no beneficiary coinsurance or deductible.

Hospital outpatient (OPPS Addendum B)

Status indicator Q4 (Conditionally packaged laboratory services), with no separate OPPS payment rate.

Medically Unlikely Edits for G0480

MUE limits for G0480: practitioner 1 (MAI 2, Code Descriptor / CPT Instruction); hospital outpatient 1 (MAI 2, Code Descriptor / CPT Instruction). The practitioner MUE is a date-of-service policy edit: units above the limit deny even when split across lines, and appeals rarely succeed.

NCCI edits and add-on rules

In the practitioner PTP file v323r0, G0480 is the column-2 (bundled) code in 17 active pairs, 6% of which allow a modifier and the column-1 code in 82 (26% modifier-allowed); 16 earlier pairs have been deleted. CMS's most frequent rationale for the bundled pairs: Mutually exclusive procedures.

G0480 is neither an add-on code nor a designated primary code in the 2026 Q4 NCCI add-on edit file.

Pair counts show exposure, not the answer for one claim. Check G0480 against a second code to see whether the pair bundles and whether a modifier can separate the services.
