ICD-10 Code H11.049 – Peripheral pterygium, stationary, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.049 – Peripheral pterygium, stationary, unspecified eye
What it is
This code identifies a peripheral pterygium that is stationary and not specified as affecting the right or left eye. It describes a conjunctival growth extending toward the cornea without evidence of progression.
Clinical signs
Findings may include a visible fibrovascular or conjunctival wedge near the corneal edge. Clinical features vary; refer to documentation for whether the lesion is stable and which eye is involved.
When to use this code
Use H11.049 when the provider documents a peripheral pterygium that is stationary and does not identify the eye laterality. It also fits follow-up notes describing a stable lesion without change over time. If the record says progressive, recurrent, or specifies another eye condition, code that instead.
Do not use for
Do not use this code for a pterygium that is documented as progressive or recurrent. Also avoid it when the chart identifies the right or left eye and a more specific laterality code is available.
Coding tip
Check the note for laterality and whether the lesion is stationary before assigning H11.049.
