N35.919 Unspecified urethral stricture, male, unspecified site

Name of the Condition

• Unspecified urethral stricture, male, unspecified site
• ICD-10 Code: N35.919

Summary

Unspecified urethral stricture, male, unspecified site refers to a narrowing of the urethra in males where the specific location of the stricture is not documented. This condition can obstruct urine flow and may lead to urinary symptoms or complications. The stricture typically results from scarring or inflammation, which reduces the urethral diameter over time.

Causes

Urethral stricture can develop due to scarring from injury, infection, inflammation, or previous medical procedures involving the urethra. Trauma, surgery, or chronic inflammation may contribute to the formation of scar tissue that narrows the urethra. Infections, such as sexually transmitted infections, or inflammatory conditions can also lead to stricture formation.

Risk Factors

• History of urethral injury or trauma
• Recurrent urinary tract infections
• Prolonged catheterization or instrumentation
• Inflammatory conditions affecting the urethra
• Previous urethral surgery or procedures

Symptoms

• Difficulty initiating urination
• Weak or intermittent urine stream
• Increased frequency or urgency of urination
• Painful urination or discomfort
• Urinary retention or incomplete bladder emptying

Diagnosis

Diagnosis typically involves a physical examination, uroflowmetry to assess urine flow, and imaging studies such as retrograde urethrogram or cystoscopy to visualize the stricture. These methods help determine the location and severity of the narrowing. Additional tests may include urine analysis or post-void residual volume measurement.

Treatment Options

• Urethral dilation to temporarily widen the stricture
• Urethrotomy (surgical incision of the stricture)
• Surgical reconstruction (urethroplasty) for severe or recurrent cases
• Intermittent self-catheterization to maintain urethral patency

Prognosis and Follow-Up

Prognosis depends on the severity and location of the stricture, as well as the chosen treatment. Early intervention often leads to better outcomes, but strictures may recur. Regular follow-up with a healthcare provider is recommended to monitor for recurrence or complications.

Complications

• Recurrent urinary tract infections
• Urinary retention or incomplete bladder emptying
• Kidney damage due to prolonged obstruction
• Formation of bladder stones
• Increased risk of urethral injury during future procedures

Lifestyle & Prevention

• Stay hydrated to promote regular urination
• Practice safe sex to reduce infection risk
• Avoid unnecessary urethral instrumentation
• Seek prompt treatment for urethral injuries or infections
• Follow post-procedure care instructions to minimize scarring

When to Seek Professional Help

Consult a healthcare provider if you experience persistent urinary symptoms, such as difficulty urinating, pain, or blood in the urine. Seek immediate care for signs of urinary retention or severe pain, as these may indicate a medical emergency.

Tips for Medical Coders

When coding N35.919, ensure the documentation specifies the condition as an unspecified urethral stricture in a male patient with an unspecified site. Verify that no more specific site (e.g., meatal or bulbous) is documented, as this would require a different code. Confirm the absence of additional details that might alter coding, such as laterality or severity, to ensure accurate assignment.
