Summary & Overview
HCPCS G9252: Adenoma or Neoplasm Detected During Screening Colonoscopy
HCPCS Level II code G9252 identifies detection of adenoma(s) or other neoplasm during a screening colonoscopy. Nationally, accurate use of this code matters for documenting screening outcomes, tracking screening program effectiveness, and ensuring appropriate billing distinction between pure screening procedures and diagnostic or therapeutic encounters when lesions are found. Clear coding supports population health monitoring and downstream quality measurement.
Key payers in common coverage analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how G9252 is applied in clinical documentation, typical sites of service, and the payer landscape relevant to screening colonoscopy claims. The publication also covers benchmarking approaches, common billing considerations, and recent policy guidance affecting screening colonoscopy documentation and coding.
This summary provides national context for clinicians, billing professionals, and health system administrators seeking to understand the code's purpose and implications for screening workflows, quality reporting, and claims processing. Data not available in the input for payer-specific reimbursement rates, modifiers, taxonomies, and ICD-10 pairings are noted elsewhere in the full publication.

Clinical & Coding Specifications
Clinical Context
A 58-year-old average-risk adult presents for screening colonoscopy. During a routine outpatient colonoscopic examination under moderate sedation at an ambulatory surgery center, the endoscopist identifies a 1.2 cm sessile polyp in the ascending colon that appears adenomatous. The endoscopist performs cold snare polypectomy, retrieves the specimen for histopathology, documents adequate bowel prep and complete polyp removal, and updates the procedure note to reflect that an adenoma was detected during a screening colonoscopy. The patient is discharged with routine post-polypectomy instructions and follow-up based on pathology.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the day of a procedure | Use when a distinct E/M is performed and documented on the same day as the colonoscopy prior to the procedure. |
| 59 | Distinct procedural service | Use when a separate, distinct endoscopic procedure or service is performed at a different anatomic site or session during the same day.
| 52 | Reduced services | Use when the colonoscopy service is partially reduced or not completed and documentation supports reduced work.
