N35.1Postinfective urethral stricture, not elsewhere classified

N35.1 is the ICD-10-CM diagnosis code for postinfective urethral stricture, not elsewhere classified. It belongs to category N35 (urethral stricture), block N30-N39 (other diseases of the urinary system) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within N35 (urethral stricture), N35.1 is specifically for postinfective urethral stricture, not elsewhere classified. Related codes cover post-traumatic urethral stricture (N35.0), other urethral stricture (N35.8) and unspecified (N35.9).

To report this condition, pick the subcode that matches the documentation: N35.11 (male) and N35.12 (female).

Don't report N35.1 together with the conditions in its Excludes1 note: urethral stricture associated with schistosomiasis (B65.-, N29), gonococcal urethral stricture (A54.01) and syphilitic urethral stricture (A52.76).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
