Code Description

ICD-10 B02.30 is a billable code used to indicate a diagnosis of zoster ocular disease, unspecified.

Key Diagnostic Point:

Zoster ocular disease, also known as herpes zoster ophthalmicus, is a viral infection caused by the reactivation of the varicella-zoster virus (VZV), which is the same virus responsible for chickenpox. This condition primarily affects the ophthalmic division of the trigeminal nerve, leading to symptoms such as unilateral eye pain, redness, swelling, and potential vision loss. Patients may present with vesicular lesions on the forehead, eyelid, or conjunctiva. Complications can include keratitis, uveitis, and postherpetic neuralgia, which can significantly impact the quality of life. The condition is more common in older adults and immunocompromised individuals. Diagnosis is typically clinical, supported by the presence of characteristic skin lesions and ocular symptoms. Early intervention with antiviral therapy can reduce the severity and duration of symptoms, making prompt recognition and treatment essential.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and symptoms among patients
  • Need for differentiation from other ocular conditions
  • Potential for complications requiring additional coding
  • Documentation of prior varicella infection or vaccination status

Audit Risk Factors

  • Inadequate documentation of symptoms and complications
  • Failure to specify the ocular involvement
  • Misclassification of the condition as a different type of zoster
  • Lack of supporting evidence for the diagnosis
