Postinfective membranous urethral stricture, NEC, male

This code describes a narrowing of the membranous urethra in a male patient that develops as a sequela of a prior infection. This stricture is not attributable to other specified causes like trauma or instrumentation. It results in obstructed urine flow and associated lower urinary tract symptoms.

Use this code for male patients diagnosed with a urethral stricture specifically located in the membranous segment, where the etiology is clearly documented as post-infectious. Documentation should confirm the history of a preceding infection (e.g., urethritis, sexually transmitted infection) and rule out other causes of stricture.

• Ensure documentation specifies "membranous" urethral stricture and a clear post-infectious etiology.
• Do not use if the stricture is due to trauma, instrumentation, or is congenital; other N35 subcategories would apply.
• Code the underlying infection (if still active and relevant) in addition to the stricture, following sequencing guidelines.
