HCPCS G9862: Documentation for Not Recommending 10-Year Colorectal Follow-Up
HCPCS Level II code G9862 captures clinician documentation of medical reasons for not recommending the guideline default of a 10‑year follow‑up interval after colorectal screening or surveillance. This code matters nationally because it standardizes reporting when clinical factors — such as inadequate bowel prep, family or personal history of colonic polyps, advanced age, or limited life expectancy — necessitate a shorter surveillance interval. Consistent use supports quality measurement, accurate encounter documentation, and claims adjudication tied to colorectal cancer screening pathways. Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical intent and service settings, typical payer coverage patterns and benchmarks where available, and relevant policy and documentation considerations that affect billing and reporting. The summary highlights where documentation drives appropriate use of G9862 and what administrative details commonly influence reimbursement and audit outcomes. Data not available in the input for associated taxonomies, ICD‑10 mappings, or related procedure codes is noted where applicable.
Billing Code Overview
HCPCS Level II code G9862 documents the medical reason(s) for not recommending at least a 10‑year follow‑up interval after colorectal screening or surveillance. Examples include inadequate bowel preparation, familial or personal history of colonic polyps, patient age or limited life expectancy, or other clinical reasons that justify a shorter follow‑up interval.
-
Service type: Documentation of clinical justification for altered colorectal surveillance intervals
-
Typical site of service: Endoscopy centers, outpatient clinics, and other facilities where colorectal screening or surveillance colonoscopy is performed

Clinical & Coding Specifications
Clinical Context
A 66-year-old patient presents for post-colonoscopy surveillance discussion after a screening colonoscopy with inadequate bowel preparation and detection of one tubular adenoma removed during the procedure. The endoscopist documents the medical rationale for recommending a surveillance interval shorter than the guideline-recommended 10 years. The clinical workflow includes review of pathology confirming adenoma, assessment of bowel prep quality, review of personal and family history of colorectal neoplasia, estimation of life expectancy and comorbidities, and generation of a formal procedure note that documents the specific medical reason(s) for not recommending at least a 10-year follow-up interval. The completed documentation is coded with HCPCS Level II code G9862 to capture the medical reason(s) for an interval shorter than 10 years. Typical site of service is an ambulatory endoscopy center or hospital outpatient endoscopy unit. Common associated interactions include pre-procedure assessment, intra-procedure findings and polypectomy, post-procedure pathology review, and follow-up scheduling conversations with the patient and primary care provider.
