Double pterygium of unspecified eye

This code signifies the presence of two separate pterygia affecting the conjunctiva and cornea of an eye, where the specific eye (right or left) is not documented. A pterygium is a triangular growth of tissue that typically starts on the conjunctiva and can extend onto the cornea, potentially impairing vision.

Utilize this code when medical record documentation clearly indicates the diagnosis of a double pterygium in a patient, but the laterality (right or left eye) is not specified. This code is appropriate when the physician's notes confirm the presence of two distinct pterygial growths in a single eye, without further detail on which eye is affected.

• Avoid using this code if the laterality is documented; instead, select the appropriate code for double pterygium of the right (H11.031) or left (H11.032) eye.
• Ensure the documentation explicitly states "double pterygium" or describes two separate pterygial growths in the same eye to support this specific code.
• Do not confuse with codes for single pterygium (H11.01-) or recurrent pterygium (H11.02-).
