Peripheral pterygium, progressive, unspecified eye
ICD-10 H11.059 is a billable code used to indicate a diagnosis of peripheral pterygium, progressive, unspecified eye.
Peripheral pterygium is a benign growth of conjunctival tissue that extends onto the cornea, typically originating from the nasal or temporal conjunctiva. It is characterized by a triangular-shaped fibrovascular tissue that can progressively invade the cornea, leading to potential visual impairment. The condition is often associated with environmental factors such as UV exposure, chronic irritation, and dry eye syndrome. Clinically, patients may present with symptoms of irritation, redness, and foreign body sensation, although some may remain asymptomatic. The anatomy involved includes the conjunctiva, cornea, and potentially the sclera if the pterygium progresses significantly. Disease progression can lead to astigmatism and visual distortion due to corneal irregularities. Diagnostic considerations include a thorough ocular examination, slit-lamp biomicroscopy, and possibly imaging studies to assess the extent of corneal involvement. Treatment options vary from observation in asymptomatic cases to surgical excision in progressive or symptomatic cases, with postoperative care focusing on preventing recurrence.

H11.059 covers progressive peripheral pterygium that is unspecified, meaning it does not specify laterality or whether it is recurrent. It includes cases where the pterygium is not clearly defined as affecting the right or left eye.
H11.059 should be used when the pterygium is progressive and unspecified, particularly when the clinician cannot determine the laterality or when the condition does not fit the criteria for other specific pterygium codes.
Documentation should include a detailed ocular examination report, noting the presence and characteristics of the pterygium, any symptoms reported by the patient, and the clinical rationale for the diagnosis and treatment plan.
