About N99.112
N99.112 is the ICD-10-CM diagnosis code for postprocedural membranous urethral stricture, male. It belongs to category N99 (intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified), block N99 (intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within N99.11 (postprocedural urethral stricture, male), N99.112 is specifically for postprocedural membranous urethral stricture, male. Related codes cover meatal (N99.110), bulbous urethral stricture, male (N99.111), anterior bulbous urethral stricture, male (N99.113), unspecified (N99.114), fossa navicularis urethral stricture (N99.115) and overlapping sites (N99.116).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 697 (Urethral Stricture, relative weight 0.97), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (title revised).
Before ICD-10, this condition was coded in ICD-9-CM as 598.2 (postoperative urethral stricture).
