Summary & Overview
CPT 4550F: Quality Measure Performance Reporting
CPT code 4550F is a Category II performance reporting code intended for capture of a specific clinical quality measure; the source record includes no descriptive summary. Category II codes support standardized reporting of clinical performance and quality metrics across care settings and are used to track adherence to recommended care processes. Nationally, such codes matter because they enable consistent measurement for quality programs, payer reporting, and value-based contracting.
This publication covers major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the code, an outline of what typical reporting use looks like, and an explanation of the kinds of benchmarks and policy updates that commonly affect Category II codes. The report also identifies gaps where input data is missing and highlights where organizations should consult payer-specific guidance for reporting requirements.
The content is written for clinicians, coding professionals, and policy analysts seeking a national-level understanding of how a Category II code like 4550F functions within quality measurement frameworks, and what to expect when integrating such a code into reporting workflows.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old with chronic constipation and symptomatic internal hemorrhoids presenting to a colorectal clinic for evaluation. After conservative therapy fails, the patient undergoes a clinic-based therapeutic procedure to assess and treat anorectal pathology. The workflow includes pre-procedure history and focused anorectal exam, informed consent, topical anesthesia or local infiltration, anoscopic or proctoscopic evaluation, delivery of the chosen therapy (such as rubber band ligation, sclerotherapy, or infrared coagulation), brief post-procedure observation, and discharge with wound care and activity instructions. Documentation includes indication, pertinent history, findings on anoscopy/proctoscopy, description of the procedure performed, estimated blood loss if any, tolerance of procedure, any immediate complications, and follow-up plan.
