Summary & Overview
CPT 53661: Female Urethral Dilation, Subsequent Insertion
CPT code 53661 denotes a subsequent insertion of urethral dilators for female patients with voiding dysfunction, typically performed to relieve urethral stricture and promote complete bladder emptying. This procedural code is part of the female urethral dilation series (53660–53665) and is used when multiple dilation insertions are required during care. The code matters nationally because urethral dilation is a common urologic procedure for symptomatic obstruction and impacts procedural coding, site-of-service decisions, and claims processing across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 53661, comparisons of payer coverage patterns and typical settings of care, and practical benchmarks for coding and documentation. The publication also summarizes common billing modifiers used with procedural codes and notes where input data are not available.
This resource is intended for billing managers, revenue cycle staff, and clinical leaders who need a national-level reference on the clinical intent and administrative use of CPT code 53661, including payer considerations and typical sites of service.

Clinical & Coding Specifications
Clinical Context
A 62-year-old female with a history of recurrent urethral stricture and incomplete bladder emptying presents to the outpatient urology clinic for a planned subsequent urethral dilation. She previously underwent an initial dilation two months ago with symptomatic improvement but now reports return of voiding difficulty and decreased urinary stream. The physician reviews prior operative note, confirms indication and need for repeat dilation, obtains informed consent, and performs the procedure in the office procedure room. Under sterile technique, progressive dilators are inserted to a larger size than the prior session; a topical anesthetic or urethral lidocaine gel is instilled beforehand. The patient is monitored briefly post-procedure for urinary retention or hematuria and discharged with voiding instructions and follow-up. Typical documentation includes indication, prior procedure date, sizes of dilators used, medications instilled (if any), patient tolerance, and post-procedure voiding status. Typical sites of service are the physician office or ambulatory surgery center depending on complexity and anesthesia needs. Service type is an outpatient procedural urology service. Typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
