H01.00A

What This Code Means

Inflammation of the eyelids on the right eye affecting both the upper and lower lids, but the specific type or cause has not been determined. This condition causes redness, irritation, and sometimes crusting or scaling of the eyelid margins.

Coding Tips

• •The 'A' suffix indicates this is the initial encounter; use 'D' for subsequent encounters and 'S' for sequela if applicable
• •Blepharitis codes require laterality specification (right, left, or bilateral) and eyelid location (upper, lower, or both); ensure documentation clearly identifies which eye and which lid(s) are affected
