Other disorders of urinary system (N39)

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.

Instructional Notations

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.

  • hematuria NOS R31
  • recurrent or persistent hematuria N02
  • recurrent or persistent hematuria with specified morphological lesion N02
  • proteinuria NOS R80

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Nocturnal Enuresis

Involuntary discharge of URINE during sleep at night after expected age of completed development of urinary control.

Urine

Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.
