Code Description

ICD-10 B01.81 is a billable code used to indicate a diagnosis of varicella keratitis.

Key Diagnostic Point:

Varicella keratitis is a viral infection of the cornea caused by the varicella-zoster virus (VZV), which is the same virus responsible for chickenpox and shingles. This condition typically occurs in individuals who have had a prior varicella infection or have been vaccinated against it. The keratitis manifests as inflammation of the cornea, leading to symptoms such as redness, pain, photophobia, and blurred vision. In severe cases, it can result in corneal scarring and vision loss. The pathophysiology involves the reactivation of the latent VZV in the sensory ganglia, which can spread to the cornea, causing epithelial and stromal keratitis. Diagnosis is primarily clinical, supported by patient history and, in some cases, laboratory confirmation. Treatment often includes antiviral medications, topical corticosteroids, and supportive care to manage symptoms. Vaccination against varicella is crucial in preventing primary infection and subsequent complications like keratitis.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of viral infections and their complications.
  • Differentiation from other types of keratitis.
  • Documentation of prior varicella infection or vaccination status.
  • Potential for co-morbid conditions affecting the eye.

Audit Risk Factors

  • Inadequate documentation of prior varicella infection.
  • Failure to specify the type of keratitis.
  • Lack of supporting clinical evidence for the diagnosis.
  • Misclassification of keratitis type.
