Other viral conjunctivitis

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

Code Description

ICD-10 B30.8 is a billable code used to indicate a diagnosis of other viral conjunctivitis.

Key Diagnostic Point:

Other viral conjunctivitis refers to inflammation of the conjunctiva caused by viral infections that do not fall under the more commonly recognized categories such as adenoviral or herpes simplex conjunctivitis. This condition can be caused by various viruses, including enteroviruses, cytomegalovirus (CMV), and varicella-zoster virus (VZV). Symptoms typically include redness, tearing, discharge, and irritation of the eye. Diagnosis is primarily clinical, based on patient history and symptomatology, but may be supported by laboratory tests such as viral cultures or polymerase chain reaction (PCR) assays to identify the specific viral pathogen. Treatment is generally supportive, focusing on symptom relief, as most viral conjunctivitis cases are self-limiting. Antiviral medications may be indicated in cases caused by specific viruses, such as herpes simplex, where topical antivirals like acyclovir can be effective. Understanding the specific viral etiology is crucial for appropriate management and to prevent complications, particularly in immunocompromised patients.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of viral pathogens that can cause conjunctivitis
  • Need for differential diagnosis with bacterial conjunctivitis
  • Potential for overlapping symptoms with other ocular conditions
  • Variability in treatment protocols based on viral etiology

Audit Risk Factors

  • Inadequate documentation of viral etiology
  • Misdiagnosis as bacterial conjunctivitis
  • Failure to document symptom duration and severity
  • Lack of follow-up notes on treatment response
