ICD-10 Code H01.124 – Discoid lupus erythematosus of left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.124 – Discoid lupus erythematosus of left upper eyelid
What it is
This code identifies discoid lupus erythematosus affecting the left upper eyelid. It is a chronic inflammatory skin disorder limited to that eyelid area.
Clinical signs
Typical findings include a well-defined, scaly, erythematous plaque with possible pigment change, atrophy, or scarring. Clinical features vary; refer to documentation.
When to use this code
Use H01.124 when the record specifically documents discoid lupus erythematosus on the left upper eyelid. Code it when the diagnosis is confirmed by the clinician and the laterality is clear. If the note only says lupus without eyelid location, check documentation.
Do not use for
Do not use this code for systemic lupus erythematosus without eyelid involvement or for nonspecific eyelid dermatitis. Check documentation if the lesion is on another eyelid or if laterality is not stated.
Coding tip
Confirm both the anatomic site and left-sided laterality before assigning H01.124.
