ICD-10 Code B30.2 – Viral pharyngoconjunctivitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B30.2 – Viral pharyngoconjunctivitis
What it is
B30.2 identifies a viral infection that affects the throat and the conjunctiva of the eyes at the same time. Use it when documentation clearly states pharyngoconjunctivitis due to a viral cause.
Clinical signs
Typical findings include sore throat, red eyes, and conjunctival irritation or discharge. Clinical features vary; refer to documentation for the specific viral syndrome recorded.
When to use this code
Use B30.2 when the provider documents viral pharyngoconjunctivitis, pharyngoconjunctival fever, or a similar combined throat-and-eye viral illness. Apply it when both sites are involved and the viral etiology is stated. Check documentation if the record only says conjunctivitis or pharyngitis alone.
Do not use for
Do not use this code for bacterial eye or throat infections, or for isolated conjunctivitis without pharyngitis. If the cause is not viral or the diagnosis is unspecified, check documentation.
Coding tip
Code the combined diagnosis only when the record supports both pharyngeal and conjunctival involvement.
