About N35.916

N35.916 is the ICD-10-CM diagnosis code for unspecified urethral stricture, male, overlapping sites. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N35.91 (urethral stricture, unspecified, male), N35.916 is specifically for unspecified urethral stricture, male, overlapping sites. Related codes cover urethral stricture, male, meatal (N35.911), bulbous urethral stricture, male (N35.912), membranous urethral stricture, male (N35.913), anterior urethral stricture, male (N35.914) and urethral stricture, male, unspecified site (N35.919).

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 was added in FY2019, effective October 1, 2018.
