ICD-10-CM Code For Other Disorders Of Urethra: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N36 includes disorders of the urethra such as urethral stricture, urethritis, and other specified and unspecified urethral conditions that affect patency, mucosa, and function. These ICD-10-CM diagnosis codes are used to document clinical presentations involving urethral inflammation, obstruction, or structural abnormalities, capturing disease severity, organ involvement, or clinical complexity relevant to this group. Accurate coding within the ICD-10-CM N36 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM N36: Other Disorders Of Urethra Overview

The ICD-10-CM N36 group captures diagnoses affecting the urethra that are not classified elsewhere, including inflammatory, structural, and functional disorders. These conditions target the lower urinary tract and can impact urinary flow, continence, and local tissue health. Accurate coding matters for appropriate claim adjudication and to reflect the clinical complexity that influences treatment and follow-up.

When to Use

Use a code from this group when the clinical record documents a urethral condition such as urethritis, urethral stricture, or other specified/unspecified urethral disorder. Select the most specific code reflecting laterality, cause, and any associated complications documented in the medical record.

Typical Clinical Scenarios

A middle-aged woman presents to urgent care with acute onset of dysuria, urinary frequency, and suprapubic discomfort after recent urinary catheter removal; exam shows urethral tenderness and purulent urethral discharge, and a point-of-care urine test is positive for leukocyte esterase but urine culture is pending. A urethral-specific infection or acute urethritis is diagnosed when symptoms localize to the urethra rather than the bladder, prompting assignment of an appropriate urethral disorder code. Typical codes: N36.0, N36.1
An elderly man with a history of benign prostatic hyperplasia reports months of weak urinary stream, hesitancy, and post-void dribbling; uroflowmetry and postvoid residual testing reveal chronic obstructive symptoms with evidence of urethral narrowing on cystoscopy. Chronic urethral stricture or obstruction causing ongoing lower urinary tract symptoms is coded from this urethral disorders group to reflect the chronic mechanical cause. Typical codes: N36.2, N36.5
A young adult hospitalized after pelvic trauma from a motor vehicle collision has hematuria, difficulty voiding, and urethral pain; retrograde urethrogram demonstrates traumatic partial urethral disruption requiring catheter placement and later urologic follow-up. Traumatic urethral injury or subsequent urethral complication is assigned a code from this group to document the urethral pathology complicating the hospitalization. Typical codes: N36.44, N36.9
