Unspecified pterygium of unspecified eye

This code signifies the presence of an unspecified pterygium, a non-cancerous growth of conjunctival tissue that extends onto the cornea. The laterality of the affected eye is also not specified in this particular code.

Use this code when documentation confirms a diagnosis of pterygium but lacks specific details regarding its type (e.g., primary, recurrent) or the affected eye (e.g., right, left, bilateral). This code is appropriate when the provider's notes simply state "pterygium" without further elaboration on laterality or specific characteristics.

• Avoid using this code if the documentation specifies the type of pterygium (e.g., H11.01- for primary, H11.02- for recurrent) or the affected eye.
• Always query the provider for clarification on laterality and specific pterygium type to allow for more precise coding.
• This code is a "catch-all" for incomplete documentation; strive for more specific codes whenever possible.
