Code Description

ICD-10 N35.113 is a billable code used to indicate a diagnosis of postinfective membranous urethral stricture, not elsewhere classified, male.

Key Diagnostic Point:

Postinfective membranous urethral stricture refers to a narrowing of the urethra that occurs as a result of a previous infection, typically involving the urethra or surrounding structures. This condition is characterized by the formation of scar tissue that can obstruct the flow of urine, leading to various urinary symptoms such as difficulty urinating, weak urine stream, and urinary retention. In males, this condition can arise from infections such as urethritis, which may be caused by sexually transmitted infections (STIs) or other bacterial infections. The stricture can be diagnosed through a combination of patient history, physical examination, and imaging studies such as retrograde urethrograms or cystoscopy. Treatment options may include dilation, urethrotomy, or surgical reconstruction, depending on the severity and location of the stricture. Accurate coding is essential for proper management and reimbursement, as this condition falls under urinary system disorders classified elsewhere.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of postinfective conditions
  • Differentiation from other types of urethral strictures
  • Knowledge of associated urinary symptoms and their implications
  • Need for precise documentation of prior infections

Audit Risk Factors

  • Inadequate documentation of prior infections
  • Failure to specify the type of stricture
  • Misclassification of the stricture type
  • Lack of supporting imaging or procedural documentation

Frequently Asked Questions

What is the primary cause of postinfective membranous urethral stricture?

The primary cause is typically a previous infection of the urethra, which leads to inflammation and subsequent scarring.

How is postinfective membranous urethral stricture diagnosed?

Diagnosis is made through patient history, physical examination, and imaging studies such as cystoscopy or retrograde urethrogram.

What are the treatment options for this condition?

Treatment options include urethral dilation, urethrotomy, or surgical reconstruction, depending on the severity of the stricture.
