ICD-10 Code H10.44 – Vernal conjunctivitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.44 – Vernal conjunctivitis
What it is
H10.44 identifies vernal conjunctivitis, a recurrent allergic inflammation of the conjunctiva. It is typically seasonal and often affects children or adolescents, especially in warmer months.
Clinical signs
Common findings include eye itching, redness, tearing, and light sensitivity. Clinical features vary; refer to documentation for papillae, limbal changes, or other exam findings.
When to use this code
Use H10.44 when the provider documents vernal conjunctivitis or vernal keratoconjunctivitis as the diagnosis. Code it for seasonal allergic eye inflammation when the record clearly identifies this condition. If the note only says “conjunctivitis,” check documentation for the specific type.
Do not use for
Do not use this code for bacterial, viral, or nonspecific allergic conjunctivitis. If the diagnosis is unclear or another eye disorder is documented instead, check documentation.
Coding tip
Confirm the provider’s exact conjunctivitis type before assigning H10.44.
