Pingueculitis, unspecified eye

This code represents inflammation of a pinguecula, a yellowish, slightly raised thickening of the conjunctiva on the white part of the eye, typically on the nasal side. Pingueculitis is characterized by redness, irritation, and sometimes a foreign body sensation, without involving the cornea.

Use this code when documentation indicates inflammation of a pinguecula without further specification of the affected eye. This diagnosis is supported by clinical examination noting conjunctival injection and irritation localized to a pre-existing pinguecula.

• Ensure the documentation specifies "unspecified eye" if laterality is not noted.
• Distinguish from pterygium (H11.0-) which involves corneal encroachment.
• Do not use if the inflammation is due to a specific infectious agent unless separately coded.
