ICD-10 Code H11.062 – Recurrent pterygium of left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.062 – Recurrent pterygium of left eye
What it is
Use this code for regrowth of a pterygium on the left eye after prior removal or treatment. It identifies a recurrent fibrovascular growth extending from the conjunctiva toward the cornea.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a visible conjunctival growth on the left eye, irritation, redness, foreign-body sensation, or corneal involvement if the lesion advances.
When to use this code
Choose H11.062 when the record clearly states recurrent pterygium in the left eye, including postoperative recurrence after earlier excision. Use it when the clinician documents left-sided recurrence rather than a new, unspecified conjunctival lesion.
If laterality is documented as left and recurrence is confirmed, this code fits the encounter. Check documentation if the note only says pterygium, history of pterygium, or bilateral disease.
Do not use for
Do not use this code for pterygium of the right eye, bilateral disease, or a primary pterygium without recurrence. Do not assign it when the chart does not confirm recurrence.
Coding tip
Verify both laterality and recurrence status in the operative note or assessment before coding H11.062.
