Unspecified pterygium of right eye

This code signifies the presence of an unspecified pterygium affecting the right eye. A pterygium is a benign, wedge-shaped growth of the conjunctiva that extends onto the cornea, typically originating from the nasal side. "Unspecified" indicates that further details regarding the type or characteristics of the pterygium are not documented.

This code is appropriate when documentation confirms a pterygium in the right eye, but the physician has not specified its type (e.g., primary, recurrent, progressive). It is used when the clinical record clearly indicates the presence of a right-sided pterygium without further descriptive detail.

• Ensure the documentation explicitly states "right eye" for laterality.
• Avoid using this code if the physician specifies the type of pterygium (e.g., recurrent, progressive); instead, use a more specific code.
• If laterality is not documented, consider querying the provider or using an unspecified laterality code if no other option is available.
