Ulcerative blepharitis left lower eyelid

This code signifies an inflammatory condition of the left lower eyelid characterized by ulceration, typically involving the lash follicles and meibomian glands. It often presents with crusting, redness, irritation, and potential lash loss along the eyelid margin. This specific code identifies the laterality and precise anatomical location of the ulcerative blepharitis.

Apply this code when documentation clearly indicates ulcerative blepharitis affecting the lower eyelid of the left eye. Supporting documentation should include a physician's diagnosis, laterality, and specific mention of ulceration or a severe form of blepharitis. This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure documentation specifies "ulcerative" blepharitis; simple blepharitis codes are distinct.
• Verify laterality (left) and eyelid location (lower) are explicitly stated in the medical record.
• Do not confuse with non-ulcerative forms of blepharitis or other eyelid inflammatory conditions.
