ICD-10 Code H11.069 – Recurrent pterygium of unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.069 – Recurrent pterygium of unspecified eye
What it is
This code identifies a pterygium that has returned after prior removal or treatment, but the affected eye is not documented. It is a fibrovascular growth of conjunctival tissue that extends onto the cornea.
Clinical signs
Common findings include a visible conjunctival growth crossing the limbus, irritation, redness, tearing, or foreign-body sensation. Clinical features vary; refer to documentation.
When to use this code
Use H11.069 when the record clearly states recurrent pterygium and does not specify right or left eye. It also fits follow-up visits documenting regrowth after prior excision or other treatment. If laterality is documented, use the more specific code instead.
Do not use for
Do not use this code for a primary, nonrecurrent pterygium. Do not use it when the chart identifies the right or left eye, or when documentation is insufficient. Check documentation.
Coding tip
Verify recurrence and laterality in the ophthalmology note before assigning H11.069.
