ICD-10 Code H01.121 – Discoid lupus erythematosus of right upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.121 – Discoid lupus erythematosus of right upper eyelid
What it is
This code identifies discoid lupus erythematosus affecting the right upper eyelid. It is a localized chronic inflammatory skin disorder that can cause scarring and pigment change on the eyelid.
Clinical signs
Typical findings include a well-defined erythematous, scaly plaque on the eyelid, sometimes with atrophy, dyspigmentation, or scarring. Clinical features vary; refer to documentation.
When to use this code
Use H01.121 when the provider documents discoid lupus erythematosus specifically on the right upper eyelid. The record should clearly identify the site and laterality. If documentation only says lupus or eyelid rash, check documentation before coding.
Do not use for
Do not use this code for systemic lupus erythematosus without eyelid involvement, or for nonspecific dermatitis, infection, or trauma of the eyelid. Check documentation if the diagnosis is uncertain.
Coding tip
Confirm both the exact diagnosis and the right upper eyelid laterality in the note before assigning H01.121.
