Tuberculosis of (inner) (middle) ear

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/05/2025

Code Description

ICD-10 A18.6 is a billable code used to indicate a diagnosis of tuberculosis of (inner) (middle) ear.

Key Diagnostic Point:

Tuberculosis of the ear, specifically affecting the inner or middle ear, is a rare but serious manifestation of extrapulmonary tuberculosis. It typically occurs in individuals with a history of pulmonary tuberculosis or those with compromised immune systems. The condition can present with symptoms such as ear pain, hearing loss, and discharge from the ear. Diagnosis is often made through a combination of clinical evaluation, imaging studies such as CT scans, and microbiological tests including sputum tests and culture of ear discharge. Treatment usually involves a prolonged course of antitubercular medications, and monitoring for drug resistance is critical due to the potential for multidrug-resistant tuberculosis (MDR-TB). Public health implications are significant, as tuberculosis is a communicable disease, necessitating contact tracing and isolation procedures for active cases. Early diagnosis and treatment are essential to prevent complications and transmission.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Rarity of the condition makes documentation less familiar to coders.
  • Need for precise clinical details to differentiate from other ear conditions.
  • Potential for co-infection with other diseases complicating the clinical picture.
  • Variability in presentation and diagnostic methods across different patients.

Audit Risk Factors

  • Insufficient documentation of clinical findings.
  • Lack of evidence for diagnostic tests performed.
  • Inadequate treatment documentation, especially regarding drug resistance.
  • Failure to document patient history of pulmonary tuberculosis.
