Central pterygium of unspecified eye
ICD-10 H11.029 is a billable code used to indicate a diagnosis of central pterygium of unspecified eye.
Central pterygium of the unspecified eye is a growth of conjunctival tissue that extends onto the cornea, typically originating from the nasal side. Clinically, it presents as a triangular or wing-shaped fibrovascular tissue that can cause visual disturbances if it encroaches on the visual axis. The anatomy involved includes the conjunctiva, cornea, and potentially the sclera, depending on the extent of the pterygium. Disease progression can vary; some patients may experience minimal symptoms, while others may have significant irritation, redness, and visual impairment. Diagnostic considerations include a thorough ocular examination, where the pterygium's size, location, and impact on vision are assessed. Slit-lamp examination is crucial for evaluating the extent of corneal involvement and ruling out other conditions such as pinguecula or other conjunctival lesions. Management may involve observation, topical medications for inflammation, or surgical intervention in cases of significant visual impairment or discomfort.

H11.029 specifically covers central pterygium of the unspecified eye, which is characterized by the growth of conjunctival tissue onto the cornea. It does not include other types of pterygium or conjunctival lesions.
H11.029 should be used when the pterygium is central and the eye involved is unspecified. If the pterygium is located on a specific eye (right or left), then H11.021 or H11.022 should be used.
Documentation should include a detailed ocular examination report, noting the size and location of the pterygium, any associated symptoms, and the impact on vision. Treatment plans and follow-up notes are also essential.
