Meibomian gland dysfunction left upper eyelid

This code signifies a functional impairment of the meibomian glands located in the left upper eyelid, leading to an altered quantity or quality of the lipid layer of the tear film. This dysfunction often results in evaporative dry eye, inflammation, and ocular surface irritation.

Apply this code when documentation specifically identifies meibomian gland dysfunction affecting the left upper eyelid. This diagnosis is typically supported by slit lamp examination findings, meibography, or expression of meibum, indicating obstruction, atrophy, or altered secretion from the glands in this specific location.

• Ensure the documentation clearly specifies "left upper eyelid" to support this laterality and eyelid specificity.
• Do not confuse with general meibomian gland dysfunction (H02.881, H02.882, H02.883, H02.889) if a more precise location is documented.
• Consider co-reporting with codes for associated conditions like dry eye syndrome (e.g., H04.12-) or blepharitis (e.g., H00.0-).
