N35.8Other urethral stricture

N35.8 is the ICD-10-CM diagnosis code for other urethral stricture. 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, choose N35.8 (Other urethral stricture) only when documentation doesn't support a more specific option: post-traumatic urethral stricture (N35.0), postinfective urethral stricture, not elsewhere classified (N35.1) and unspecified (N35.9).

To report this condition, pick the subcode that matches the documentation: N35.81 (male) and N35.82 (female).

Don't report N35.8 together with the conditions in its Excludes1 note: postprocedural urethral stricture (N99.1-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 598.8 (other specified causes of urethral stricture).
