Pingueculitis, left eye

This code represents inflammation of a pinguecula in the left eye. A pinguecula is a yellowish, slightly raised thickening of the conjunctiva, typically on the nasal side of the sclera, that does not involve the cornea. Pingueculitis indicates an acute inflammatory process affecting this benign growth.

Use this code when documentation specifies inflammation of a pinguecula affecting the patient's left eye. This typically occurs in response to environmental irritants like dust, wind, or sun exposure. Documentation should clearly state "pingueculitis" and laterality.

• Confirm laterality; separate codes exist for the right eye and bilateral involvement.
• Distinguish from pterygium (H11.0-), which involves corneal encroachment.
• Ensure the documentation specifies inflammation; if only a pinguecula is present without inflammation, use H11.812 (Pinguecula, left eye).
