Other disorders of urinary system (N39) ICD-10-CM
The N39 code range covers other disorders of urinary system with 17 ICD-10-CM diagnosis codes. 14 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 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the N39 Code Range
The ICD-10 code section N39 covers a variety of other urinary system disorders not classified elsewhere. These codes are primarily used to identify specific conditions such as different types of urinary tract infections and various forms of urinary incontinence, including stress, urge, mixed, and nocturnal enuresis.
This set of codes helps accurately document disorders like N39.0 for urinary tract infections (UTIs) where the infection site is unspecified, which includes infections caused by bacteria such as Escherichia coli or complications like catheter-associated UTIs. The codes for urinary incontinence (N39.3 to N39.49) capture conditions like stress incontinence (sometimes called female or male stress incontinence), urge incontinence, post-void dribbling, and continuous leakage. These synonyms clarify that whether a patient experiences primary stress incontinence, postoperative urinary incontinence, or mixed urinary incontinence, the appropriate ICD-10 code from this range applies. Other specified urinary disorders, including unusual genitourinary symptoms and unspecified urinary system disorders, are coded under N39.8 and N39.9, respectively. Overall, the ICD-10 code for other disorders of the urinary system (N39) is essential for distinguishing these diverse and sometimes complex urinary conditions in clinical records and billing.
