H30.90

What This Code Means

This code describes inflammation of the choroid and retina (the light-sensitive layers at the back of the eye) when the specific type and location are not documented. It is used when a patient has eye inflammation but the medical record lacks sufficient detail to assign a more specific diagnosis.

Coding Tips

• •Query the provider if additional documentation is available regarding the type of chorioretinal inflammation (such as focal, multifocal, or diffuse) or which eye is affected, as this would allow for a more specific code assignment
• •Verify whether the inflammation is secondary to another condition (such as syphilis, tuberculosis, or sarcoidosis) as these would require additional codes and may change the primary diagnosis code selection
