H11.9

What This Code Means

A general eye condition affecting the conjunctiva (the clear membrane covering the white part of the eye) where the specific type of disorder has not been identified or documented.

Coding Tips

• •Use this code only when the specific conjunctival disorder cannot be determined; review documentation for more specific diagnoses like conjunctivitis or pterygium
• •This is a catch-all code, so attempt to obtain clarification from the provider about the nature of the conjunctival problem before coding
