Code Description

ICD-10 N37 is a billable code used to indicate a diagnosis of urethral disorders in diseases classified elsewhere.

Key Diagnostic Point:

Urethral disorders classified under code N37 encompass a range of conditions affecting the urethra that are secondary to diseases classified elsewhere. This includes urethritis, which is inflammation of the urethra often caused by infections, and urethral strictures, which are narrowing of the urethra due to scarring or injury. These disorders can lead to significant urinary symptoms such as dysuria, urinary frequency, and obstructive voiding symptoms. The underlying diseases may include systemic conditions like diabetes, sexually transmitted infections, or malignancies that indirectly affect the urethra. Accurate coding requires a thorough understanding of the primary condition leading to the urethral disorder, as well as the specific nature of the urethral involvement. Clinicians must document the etiology and any associated symptoms to ensure appropriate coding and treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of underlying diseases causing urethral disorders.
  • Differentiation between primary urethral disorders and those secondary to other conditions.
  • Documentation must specify the nature of the urethral disorder.
  • Potential for multiple underlying conditions complicating the diagnosis.

Audit Risk Factors

  • Inadequate documentation of the underlying disease.
  • Failure to specify the type of urethral disorder.
  • Misclassification of urethral disorders as primary rather than secondary.
  • Lack of clarity in clinical notes regarding symptoms and their relation to the urethral condition.

Specialty Focus

Documentation Requirements

Detailed clinical notes on the patient's history, examination findings, and diagnostic tests.

Common Clinical Scenarios

Patients presenting with dysuria, urinary retention, or recurrent urinary tract infections.

Billing Considerations

Ensure that the primary disease causing the urethral disorder is clearly documented.

Infectious Disease

Documentation Requirements

Thorough documentation of infectious etiology and treatment response.

Common Clinical Scenarios

Patients with urethritis secondary to STIs or other infections.

Billing Considerations

Document the specific infectious agent and any relevant lab results.

Coding Guidelines

Inclusion Criteria

Use N37 When
  • According to ICD
  • 10 guidelines, N37 should be used when the urethral disorder is a direct consequence of another disease
  • Coders must ensure that the primary condition is coded first, followed by N37 to indicate the urethral involvement

Exclusion Criteria

Do NOT use N37 When
No specific exclusions found.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of urethral disorders, improving the ability to capture the complexity of these conditions and their relationship to other diseases.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of urethral disorders, improving the ability to capture the complexity of these conditions and their relationship to other diseases.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of urethral disorders, improving the ability to capture the complexity of these conditions and their relationship to other diseases.

Frequently Asked Questions

When should I use N37?

Use N37 when the urethral disorder is a direct result of another disease, ensuring that the primary condition is documented.
