Summary & Overview
CPT 3776F: Colonoscopy Screening, No Adenoma Detected
CPT code 3776F denotes a colonoscopy screening in which the provider used a colonoscope on a patient aged 50 or older and documented that no adenoma or other neoplasm was identified. This performance-measure style code captures negative findings during colorectal cancer screening and is used in quality reporting and encounter documentation. Nationally, accurate capture of negative screening results supports population-level screening metrics, care continuity, and quality measurement for colorectal cancer prevention.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis framework covers payer coverage patterns, common claim modifiers, and benchmarks for documentation and coding consistency.
Readers will find a concise explanation of the clinical context for 3776F, typical sites of service, and how the code fits into screening workflows. The publication provides benchmarks and coding considerations relevant to billing and quality reporting, as well as a summary of payer coverage landscapes and documentation practices. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 55-year-old average-risk adult presenting for routine colorectal cancer screening. The patient has no bowel symptoms, no prior colonoscopic findings, and no family history that would indicate earlier surveillance. Pre-procedure workflow includes a clinic visit or pre-op call confirming informed consent, bowel preparation instructions, medication reconciliation (especially anticoagulants), and screening for anesthesia risk. On the day of service the patient undergoes a screening colonoscopy in an outpatient endoscopy suite or ambulatory surgery center under monitored anesthesia care. The endoscopist advances a colonoscope to the cecum, inspects the mucosa thoroughly, and documents that no adenoma or other neoplasm was identified. The procedure is coded to reflect a negative screening colonoscopy in a patient age 50 or older with documentation that no adenoma or other neoplasm was found (3776F). Typical site of service: outpatient endoscopy center or hospital outpatient department. Common encounter modifiers include 52 (reduced services) and 53 (discontinued procedure) when applicable.
