Pinguecula, right eye

This code describes a pinguecula, which is a common, benign, yellowish-white growth on the conjunctiva, typically located on the nasal side of the cornea. It is a degenerative condition of the conjunctival stroma, characterized by elastotic degeneration of collagen and thinning of the overlying epithelium. This specific code indicates the presence of a pinguecula in the right eye.

Use this code when documentation clearly identifies a pinguecula affecting the right eye. This often occurs in patients with chronic exposure to sunlight, wind, or dust. Supporting documentation should include an ophthalmological examination noting the characteristic appearance and location of the lesion.

• Differentiate from pterygium (H11.0-), which involves corneal invasion.
• Ensure laterality is accurately documented and coded; this code is specific to the right eye.
• If both eyes are affected, use the appropriate codes for the right (H11.151) and left (H11.152) eyes, or the bilateral code (H11.153) if applicable and documented.
