ICD-10 Code H10.81 – Pingueculitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.81 – Pingueculitis
What it is
H10.81 identifies inflammation of a pinguecula, a small conjunctival lesion on the white of the eye. Use this code when the record states pingueculitis or inflamed pinguecula.
Clinical signs
Typical findings include localized redness, irritation, foreign-body sensation, and tenderness at the pinguecula. Clinical features vary; refer to documentation.
When to use this code
Use H10.81 when the provider documents pingueculitis as the diagnosis, even if the note also describes conjunctival irritation. Code it when the inflammation is specifically tied to the pinguecula, not just general eye redness.
Do not use for
Do not use this code for an uncomplicated pinguecula without inflammation. Check documentation if the record instead describes conjunctivitis, pterygium, or another ocular surface disorder.
Coding tip
Look for the exact phrase “pingueculitis” or “inflamed pinguecula” in the assessment before assigning H10.81.
