TL;DR
CMS describes HCPCS G0476, added in 2015, as "Infectious agent detection by nucleic acid (dna or rna); human papillomavirus (hpv), high-risk types (e.g., 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68) for cervical cancer screening, must be performed in addition to pap test". The 2026 Q4 clinical laboratory fee schedule pays G0476 $35.09 (national limitation amount). Its 2026 Q4 MUEs per date of service: practitioner 1 (MAI 2, CMS Policy); hospital outpatient 1 (MAI 2, CMS Policy). In the NCCI PTP files v323r0 G0476 appears in 281 practitioner pairs as column 2 and 21 as column 1 (most often with 0008U, 0010U, 0016U), and in 281 hospital outpatient pairs as column 2 and 21 as column 1. No current LCD or billing article lists G0476; its HCPCS coverage code is C (carrier judgment, so the Medicare contractor decides coverage). OPPS status indicator A: Services not paid under OPPS; paid under fee schedule or other payment system. HCPCS record: BETOS T2D (other tests - other); pricing indicator 13; type of service 5 (diagnostic laboratory). 1 other active code opens with "Infectious agent detection by nucleic acid"; related codes: G0567, G0475, G0473, G0472.
G0476 descriptor and code status
The October 2026 HCPCS Level II file describes G0476 as “Infectious agent detection by nucleic acid (dna or rna); human papillomavirus (hpv), high-risk types (e.g., 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68) for cervical cancer screening, must be performed in addition to pap test”. It sits in the G section (procedures and professional services, temporary), listed with the other G codes. Although searches often call it the "G0476 CPT code", G0476 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.

G0476 is paid at $35.09 (national limitation amount). Laboratory fee schedule payments carry no beneficiary coinsurance or deductible.
Hospital outpatient (OPPS Addendum B)
Status indicator A (Services not paid under OPPS; paid under fee schedule or other payment system), with no separate OPPS payment rate.
Medically Unlikely Edits for G0476
Its 2026 Q4 MUEs per date of service: practitioner 1 (MAI 2, CMS Policy); hospital outpatient 1 (MAI 2, CMS Policy). The practitioner MUE is a date-of-service policy edit: units above the limit deny even when split across lines, and appeals rarely succeed.
| Setting | MUE (units/DOS) | MAI | CMS rationale |
|---|---|---|---|
| Practitioner services | 1 | 2 Date of Service Edit: Policy | CMS Policy |
| Facility outpatient hospital | 1 | 2 Date of Service Edit: Policy | CMS Policy |
The MUE lookup for G0476 shows every setting next to any other code on the same claim.
NCCI edits and add-on rules
In the practitioner PTP file v323r0, G0476 is the column-2 (bundled) code in 281 active pairs, 99% of which allow a modifier and the column-1 code in 21 (95% modifier-allowed); 16 earlier pairs have been deleted. CMS's most frequent rationale for the bundled pairs: CPT Manual or CMS manual coding instruction.
