Peripheral pterygium, stationary, unspecified eye
ICD-10 H11.049 is a billable code used to indicate a diagnosis of peripheral pterygium, stationary, unspecified eye.
Peripheral pterygium is a benign growth of conjunctival tissue that extends onto the cornea, typically originating from the nasal or temporal conjunctiva. This condition is characterized by a triangular or wing-shaped appearance and can lead to visual disturbances if it encroaches on the visual axis. The anatomy involved includes the conjunctiva, sclera, and cornea, with the anterior segment of the eye being primarily affected. Although classified as stationary, peripheral pterygium can progress slowly over time, potentially leading to irritation, redness, and astigmatism due to corneal distortion. Diagnostic considerations include a thorough ocular examination, where the growth's size, location, and impact on vision are assessed. Differential diagnoses may include other conjunctival lesions, such as pinguecula or conjunctival cysts. Treatment options vary based on symptoms and may include observation, lubricating eye drops, or surgical excision in cases of significant visual impairment or discomfort.

H11.049 specifically covers stationary peripheral pterygium that is not specified as affecting either the right or left eye. It is important to differentiate it from other types of pterygium and conjunctival lesions.
H11.049 should be used when the pterygium is stationary and the eye affected is unspecified. If the pterygium is affecting a specific eye, the appropriate code for that eye should be used instead.
Documentation should include a detailed description of the pterygium's characteristics, its location, any associated symptoms, and the impact on the patient's vision. Visual acuity measurements and notes on treatment decisions are also essential.
