Meibomian gland dysfunction of unsp, unspecified eyelid

This code represents a general diagnosis of meibomian gland dysfunction (MGD) affecting an unstated eye and an unstated eyelid. MGD is a chronic, diffuse abnormality of the meibomian glands, commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in the glandular secretion. This can lead to tear film instability, ocular surface inflammation, and symptoms of dry eye.

Use this code when the medical record clearly indicates a diagnosis of meibomian gland dysfunction but does not specify which eye (right, left, or bilateral) or which eyelid (upper or lower) is affected. This code is appropriate when the provider's documentation is vague regarding laterality and specific eyelid involvement, and further clarification cannot be obtained.

• Avoid using this code if laterality (right, left, bilateral) or specific eyelid involvement is documented; instead, use a more specific code from the H02.88- subcategory.
• Query the provider for more specific documentation regarding the affected eye and eyelid whenever possible to allow for a more precise code assignment.
• This code should be used as a last resort when specificity is truly unknown and cannot be clarified.
