Summary & Overview
HCPCS G6028: High-Resolution Anoscopy with Biopsy
HCPCS Level II code G6028 denotes high-resolution anoscopy (HRA) with magnification and chemical agent enhancement performed with biopsy. The code captures a diagnostic, procedure-based service used to visualize and sample suspicious anal and perianal lesions, combining enhanced visualization techniques with tissue sampling. Nationally, this code matters for accurate reporting of diagnostic anoscopy services and for tracking utilization of advanced diagnostic techniques in anal disease and cancer screening pathways.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for HRA with biopsy, the expected site of service, and the types of benchmarks and policy considerations that affect coverage and coding practices. The publication outlines reimbursement benchmarking, common billing challenges, and recent policy updates that influence how payers and providers document and bill for diagnostic anoscopy services. Clinical implications for coding consistency and implications for tracking procedure utilization are summarized to aid revenue cycle and clinical teams.

Billing Code Overview
HCPCS Level II code G6028 describes high-resolution anoscopy (HRA) with magnification and chemical agent enhancement, performed with biopsy(ies). This procedure involves detailed visual examination of the anal canal and perianal region using magnified optics and topical agents to highlight abnormal tissue, and includes sampling tissue via biopsy during the same encounter.

Service type: Diagnostic procedure with biopsy
-
Typical site of service: Ambulatory surgical center or outpatient clinic (procedure room)
Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with a history of chronic anal pain and bleeding is referred to a colorectal specialist after abnormal findings on digital rectal exam and anoscopy with standard resolution. The clinician schedules a high-resolution anoscopy (HRA) with chemical enhancement and magnification, with targeted biopsy of suspicious lesions to evaluate for high-grade squamous intraepithelial lesions or anal intraepithelial neoplasia. The procedure is performed in an outpatient endoscopy or procedure suite with the patient in the left lateral or lithotomy position. After topical anesthesia and application of a chemical contrast agent (such as acetic acid or toluidine blue) to highlight abnormal epithelium, the clinician uses a high-resolution anoscope with magnified visualization to inspect the anorectal mucosa, identifies abnormal areas, directs one or more biopsy instruments, obtains tissue samples, documents location and number of biopsies, provides hemostasis as needed, and sends specimens for histopathology. Typical monitoring, recovery, and post-procedure instructions are provided, including activity restrictions and signs of complications to report.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when a distinct E/M is medically necessary and documented in addition to the HRA with biopsy on the same date |
