Pingueculitis, right eye

This code describes inflammation of a pinguecula, a yellowish, slightly raised thickening of the conjunctiva, specifically affecting the right eye. A pinguecula is a common, benign growth on the conjunctiva, often caused by exposure to sun, wind, and dust. Pingueculitis indicates an acute inflammatory process occurring within this pre-existing lesion.

This code is appropriate when documentation specifies inflammation of a pinguecula and clearly indicates the right eye as the affected site. Clinical notes should describe symptoms such as redness, irritation, or foreign body sensation localized to the pinguecula on the right eye. It is used when the physician diagnoses an acute inflammatory episode of a pinguecula.

• Ensure the documentation specifies "right eye" to support laterality.
• Do not confuse with pterygium (H11.0-), which is a fleshy growth that can invade the cornea.
• If both eyes are affected, use the appropriate bilateral code (H10.813) or separate codes for each eye if laterality is specified for each.
