Urethral stricture (N35) ICD-10-CM
The N35 code range covers urethral stricture with 39 ICD-10-CM diagnosis codes. 29 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the N35 range.
Urethra
A tube that transports URINE from the URINARY BLADDER to the outside of the body in both the sexes. It also has a reproductive function in the male by providing a passage for SPERM.
Urethral Stricture
Narrowing of any part of the URETHRA. It is characterized by decreased urinary stream and often other obstructive voiding symptoms.
About the N35 Code Range
The ICD-10 code N35 series is used to classify various types of urethral strictures, which refer to narrowing or blockage of the urethra. These codes specify the cause, location, and patient’s sex to ensure precise diagnosis and treatment documentation.
The codes cover post-traumatic urethral stricture (e.g., N35.0 for traumatic injury-related narrowing), including detailed male site-specific options such as meatal (N35.010), bulbous (N35.011), membranous (N35.012), and anterior strictures (N35.013). For females, childbirth-related strictures are coded as N35.021. The postinfective urethral stricture codes (N35.1 series) apply when the narrowing follows an infection, with male-specific subcodes identifying exact locations. Other and unspecified strictures are classified under N35.8 and N35.9, with distinctions for male and female patients and specific or unknown sites. Synonyms like “stenosis of urinary meatus” and “penile urethral stricture” help clarify coding choices, assisting clinicians and coders in selecting the precise ICD-10 code for conditions such as urethral spasm, traumatic bulbar stricture, or postobstetric urethral stricture.
