ICD-10 Code H11.061 – Recurrent pterygium of right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.061 – Recurrent pterygium of right eye
What it is
This code identifies a pterygium that has grown back in the right eye after prior treatment or removal. Use it when the chart clearly documents recurrence, not a first-time lesion.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe a recurrent fibrovascular growth extending from the conjunctiva onto the cornea, with irritation, redness, or visual disturbance if the lesion advances.
When to use this code
Use H11.061 when the provider documents recurrent pterygium specifically in the right eye. It fits follow-up visits, postoperative recurrence, or encounters where the lesion is again present after prior excision. If laterality or recurrence is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for pterygium of the left eye, bilateral disease, or an initial pterygium without recurrence. If the record only says “pterygium” or “eye irritation,” check documentation.
Coding tip
Confirm both recurrence and right-eye laterality in the provider note before coding.
