Pinguecula, bilateral

This code signifies the presence of a pinguecula affecting both eyes. A pinguecula is a common, benign, yellowish-white, slightly raised lesion on the conjunctiva, typically located on the nasal side of the limbus, but can also occur temporally. It represents a degenerative change in the conjunctival collagen and elastic fibers.

Apply this code when documentation confirms the diagnosis of pinguecula in both the right and left eyes. This is commonly seen in patients with chronic exposure to sunlight, wind, or dust. Supporting documentation should clearly state "bilateral pinguecula" or specify pinguecula in both eyes.

• Do not confuse with pterygium (H11.0-), which involves corneal encroachment.
• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code (H11.151 or H11.152).
• Code any associated symptoms, such as irritation or foreign body sensation, as secondary diagnoses if documented.
