ICD-10 Code H01.122 – Discoid lupus erythematosus of right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.122 – Discoid lupus erythematosus of right lower eyelid
What it is
This code identifies discoid lupus erythematosus affecting the right lower eyelid. It is used when documentation specifies this localized lupus lesion in that exact eyelid.
Clinical signs
Clinical features vary; refer to documentation. Typical descriptions may include a chronic, scaly, erythematous plaque with possible scarring or pigment change on the eyelid.
When to use this code
Use H01.122 when the provider documents discoid lupus erythematosus limited to the right lower eyelid. Code it from ophthalmic or dermatologic documentation that clearly identifies the site and diagnosis. If the record only says lupus or eyelid rash, check documentation before assigning this code.
Do not use for
Do not use this code for systemic lupus erythematosus without a documented discoid eyelid lesion. Do not use it when the affected eyelid is left, upper, or unspecified.
Coding tip
Verify both the lupus type and the exact eyelid laterality in the note before coding.
