Pinguecula, left eye

This code describes a benign, yellowish, slightly raised thickening of the conjunctiva, specifically located on the left eye. It is a common degenerative condition, often found on the nasal side of the cornea, and does not involve the cornea itself.

Use this code when documentation clearly indicates the presence of a pinguecula affecting the left eye. This typically occurs in patients with chronic exposure to sunlight, wind, or dust. Supporting documentation would include an ophthalmological examination noting the characteristic lesion and its laterality.

• Ensure the documentation specifies "left eye" to avoid laterality errors.
• Do not confuse with pterygium (H11.0-), which involves corneal encroachment.
• Code only if the pinguecula is explicitly diagnosed; incidental findings without clinical significance may not warrant coding.
