Peripheral pterygium, stationary, left eye
ICD-10 H11.042 is a billable code used to indicate a diagnosis of peripheral pterygium, stationary, left eye.
Peripheral pterygium is a benign growth of conjunctival tissue that extends onto the cornea, typically originating from the nasal or temporal conjunctiva. In the case of H11.042, the pterygium is stationary, indicating that it has not progressed in size or severity. Clinically, patients may present with symptoms such as irritation, redness, or a foreign body sensation in the affected eye. The anatomy involved includes the conjunctiva, which is the mucous membrane covering the white part of the eye, the sclera, and the cornea. Disease progression can vary; while some pterygia remain stable, others may grow and potentially affect vision by inducing astigmatism or obstructing the visual axis. Diagnostic considerations include a thorough eye examination, where the growth's appearance, location, and any associated symptoms are assessed. Differential diagnoses may include other conjunctival lesions such as conjunctival cysts or neoplasms. Proper identification and documentation of the condition are crucial for appropriate management and coding.

H11.042 specifically covers stationary peripheral pterygium in the left eye. It does not include other types of pterygia or conjunctival lesions.
H11.042 should be used when the pterygium is confirmed as stationary and located in the left eye. If the pterygium is in the right eye or bilateral, corresponding codes H11.041 or H11.043 should be used.
Documentation should include a detailed clinical examination report describing the pterygium's size, location, and any associated symptoms. Photographic evidence may also support the diagnosis.
