Code Description

ICD-10 H71.33 is a billable code used to indicate a diagnosis of diffuse cholesteatosis, bilateral.

Key Diagnostic Point:

Diffuse cholesteatosis, bilateral, is a condition characterized by the abnormal accumulation of cholesteatoma tissue in both ears, leading to potential complications such as hearing loss, otitis media, and vestibular dysfunction. Cholesteatomas are cyst-like lesions that can erode surrounding structures, including the mastoid process, and may result from chronic ear infections or eustachian tube dysfunction. Clinically, patients may present with symptoms such as ear fullness, drainage, tinnitus, and progressive hearing loss. Diagnosis typically involves otoscopic examination, audiometry, and imaging studies like CT scans to assess the extent of the disease and any associated complications. Management often requires surgical intervention to remove the cholesteatoma and restore ear function, with follow-up care to monitor for recurrence. The bilateral nature of the condition necessitates careful evaluation and treatment planning to address both ears simultaneously, which can complicate the clinical management and coding process.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Bilateral nature of the condition complicates documentation.
  • Requires detailed clinical history and imaging studies for accurate diagnosis.
  • Potential for associated conditions like otitis media and hearing loss.
  • Surgical interventions may vary significantly based on the extent of cholesteatosis.

Audit Risk Factors

  • Inadequate documentation of bilateral involvement.
  • Failure to document associated symptoms or complications.
  • Lack of imaging studies to support diagnosis.
  • Insufficient detail in surgical reports.

Coding Guidelines

Inclusion Criteria

Use H71.33 When
  • According to ICD
  • 10 coding guidelines, H71
  • 33 should be used when there is clear documentation of diffuse cholesteatosis affecting both ears
  • It is essential to include details about the clinical presentation, diagnostic imaging, and any surgical procedures performed

Exclusion Criteria

Do NOT use H71.33 When
  • Exclusion criteria include conditions that do not involve cholesteatosis or are limited to one ear

Frequently Asked Questions

What is the primary cause of diffuse cholesteatosis?

Diffuse cholesteatosis is primarily caused by chronic ear infections and eustachian tube dysfunction, leading to the accumulation of skin cells and debris in the middle ear.

How is diffuse cholesteatosis diagnosed?

Diagnosis is made through clinical evaluation, audiometric testing, and imaging studies such as CT scans to assess the extent of cholesteatoma.

What are the treatment options for diffuse cholesteatosis?

Treatment typically involves surgical intervention to remove the cholesteatoma and restore ear function, along with follow-up care to monitor for recurrence.
