Pinguecula, unspecified eye

This code signifies a pinguecula, which is a common, benign, yellowish patch or bump on the conjunctiva, typically on the nasal side of the sclera, near the cornea. It is a degenerative condition of the conjunctiva caused by exposure to ultraviolet light, wind, and dust, and does not involve the cornea.

Apply this code when documentation confirms the presence of a pinguecula without specifying laterality (e.g., "pinguecula noted," "patient has a pinguecula"). This code is appropriate when the medical record does not indicate whether the condition affects the right, left, or both eyes.

• Do not use this code if the documentation specifies laterality; instead, select the appropriate code for right (H11.151), left (H11.152), or bilateral (H11.153) pinguecula.
• Differentiate from pterygium (H11.0-), which involves corneal invasion, whereas pinguecula does not.
• Ensure the physician's notes clearly state "pinguecula" and do not imply another conjunctival or corneal condition.
