Code Description

ICD-10 N35.12 is a billable code used to indicate a diagnosis of postinfective urethral stricture, not elsewhere classified, female.

Key Diagnostic Point:

Postinfective urethral stricture in females refers to a narrowing of the urethra that occurs as a consequence of a previous infection, typically urethritis. This condition can arise from various infectious agents, including sexually transmitted infections (STIs) such as gonorrhea or chlamydia, or non-STI-related infections. The scarring and inflammation resulting from the infection can lead to a significant reduction in the urethral lumen, causing obstructive symptoms such as dysuria, urinary frequency, urgency, and in severe cases, urinary retention. Diagnosis often involves a combination of patient history, physical examination, and imaging studies such as retrograde urethrograms or cystoscopy. Treatment options may include urethral dilation, urethrotomy, or surgical reconstruction, depending on the severity and location of the stricture. Accurate coding is essential for proper management and reimbursement, as well as for tracking the prevalence of this condition in female patients.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between postinfective and other types of urethral strictures.
  • Understanding the specific infectious agents involved.
  • Documenting the severity and symptoms accurately.
  • Navigating related codes for urinary disorders.

Audit Risk Factors

  • Inadequate documentation of the infection history.
  • Failure to specify the type of infection leading to the stricture.
  • Misclassification of the stricture type.
  • Lack of supporting diagnostic imaging reports.

Specialty Focus

Medical Specialties

Urology

Documentation Requirements

Detailed history of urinary symptoms, previous infections, and diagnostic imaging results.

Common Clinical Scenarios

Patients presenting with urinary obstruction, recurrent urinary tract infections, or post-surgical complications.

Billing Considerations

Urologists must document the specific nature of the stricture and any prior treatments to ensure accurate coding.

Infectious Disease

Documentation Requirements

Comprehensive history of infections, including laboratory results and treatment responses.

Common Clinical Scenarios

Patients with recurrent infections leading to complications such as strictures.

Billing Considerations

Infectious disease specialists should provide clear documentation linking infections to subsequent urinary complications.

Coding Guidelines

Inclusion Criteria

Use N35.12 When
  • According to ICD
  • 10 guidelines, N35
  • 12 should be used when the urethral stricture is specifically due to a postinfective process and not classified elsewhere
  • Coders must ensure that the documentation supports the diagnosis and that no other codes apply

Exclusion Criteria
