Code Description

ICD-10 B05.81 is a billable code used to indicate a diagnosis of measles keratitis and keratoconjunctivitis.

Key Diagnostic Point:

Measles keratitis and keratoconjunctivitis are ocular complications associated with measles virus infection. Keratitis refers to inflammation of the cornea, while keratoconjunctivitis involves inflammation of both the cornea and conjunctiva. These conditions can arise during the acute phase of measles, typically presenting with symptoms such as redness, photophobia, tearing, and blurred vision. The measles virus, an RNA virus, can lead to significant ocular morbidity, particularly in malnourished individuals or those with compromised immune systems. The pathophysiology involves direct viral invasion of the ocular tissues, leading to inflammation and potential scarring. Early diagnosis and management are crucial to prevent complications such as corneal ulceration or vision loss. Vaccination against measles is highly effective and is the primary preventive measure, significantly reducing the incidence of measles and its associated complications, including keratitis and keratoconjunctivitis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of viral infections and their complications.
  • Differentiation from other forms of keratitis and conjunctivitis.
  • Documentation must specify the relationship to measles infection.
  • Potential for co-morbid conditions affecting the eye.

Audit Risk Factors

  • Inadequate documentation linking keratitis to measles.
  • Failure to note vaccination history.
  • Misclassification with other viral conjunctivitis codes.
  • Lack of detail in clinical notes regarding symptoms and treatment.
