Summary & Overview
CPT 53621: Urethral Dilation for Male Urethral Stricture
CPT code 53621 denotes urethral dilation using instruments such as a filiform and follower in a male patient to relieve urethral stricture and improve urinary flow. This ambulatory urology procedure is commonly performed in clinic or outpatient procedure settings and is relevant for managing obstructive voiding symptoms and preventing recurrent urinary tract infections. Nationally, the code matters because urethral stricture and its interventions affect procedural volumes, resource use in outpatient urology, and payer coverage policies for office-based invasive procedures.
Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, standard sites of service, and what to expect in claims handling for subsequent visits where this code applies. The publication summarizes common billing modifiers and highlights service-line considerations for urology ambulatory care. Data on associated taxonomies, ICD-10 diagnoses, and related codes are not provided in the input and are noted as unavailable where applicable.
This summary equips billing managers, urology clinicians, and policy analysts with a concise reference to CPT code 53621, its clinical purpose, and the payer landscape relevant to national practice.

Clinical & Coding Specifications
Clinical Context
A 58-year-old man with a history of recurrent urethral stricture presents to the urology clinic with decreased urinary stream, hesitancy, and intermittent urinary tract infections. He previously underwent urethral dilation several months ago. After focused history and uroflowmetry showing reduced peak flow, the urologist performs office-based urethral dilation using filiforms and followers to mechanically pass the narrowed segment and re-establish lumen patency. The procedure is typically done under local anesthetic with or without sedation, with sterile technique and prophylactic antibiotics per clinic protocol. Post-procedure care includes observation for hematuria or urinary retention, instructions for hydration, and a follow-up visit to assess symptom improvement and consider definitive repair if strictures recur. This procedure code 53621 is used for subsequent visits when repeat dilation is performed in a male patient to improve urinary flow and reduce infection risk.
