Question: What is the correct procedure code for a posterior urethroplasty associated with a diagnosis of a traumatic urethral stricture? Indiana Subscriber Answer: Assuming your physician’s documentation is sufficient, the correct code is 53415 (Urethroplasty transpubic or perineal, 1 stage, for reconstruction or repair of prostatic or membranous urethra). ICD-10 includes multiple diagnoses for urethral stricture under code family N35.0 (Post traumatic urethral stricture). The correct diagnosis for this scenario would be N35.012 (Post-traumatic membranous urethral stricture).
