About the N36 Code Range
The ICD-10 codes in the N36 section are used to identify and classify a variety of less common or less specifically coded disorders affecting the urethra, the tube that carries urine from the bladder out of the body. These codes encompass conditions such as urethral fistulas, diverticula, caruncles, functional and muscular issues, false passages, and other specified or unspecified urethral disorders.
These codes help healthcare professionals document conditions like urethral fistula (N36.0), also known by terms such as urethrorectal fistula or acquired urethrocutaneous fistula, and urethral diverticulum (N36.1), sometimes called degenerative urethral disorder. The code N36.2 covers urethral caruncle, which may also be referred to as a polyp of the urethra. Functional and muscular disorders are detailed in codes like N36.4 and its subsets, including hypermobility (N36.41) and intrinsic sphincter deficiency (N36.42). The classification also includes other distinct entities such as urethral false passage (N36.5) and a range of other specified conditions listed under N36.8, which cover diverse problems like urethral granuloma, prolapse, cysts, or hemorrhage. When the specific disorder is unknown, N36.9 is used for unspecified urethral disorders. These detailed codes facilitate precise diagnosis and treatment documentation, making the ICD-10 code for other disorders of urethra essential for accurate healthcare records related to urethral health issues.
