ICD-10 Code H01.126 – Discoid lupus erythematosus of left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.126 – Discoid lupus erythematosus of left eye, unspecified eyelid
What it is
This code identifies discoid lupus erythematosus affecting the left eye area when the eyelid is not further specified. Use it when the record documents a localized lupus lesion around the eye, but does not name the upper or lower eyelid.
Clinical signs
Findings may include a chronic, well-defined inflammatory skin lesion with scaling, erythema, or scarring around the left eye. Clinical features vary; refer to documentation.
When to use this code
Use H01.126 when the clinician documents discoid lupus erythematosus involving the left eye region and does not specify which eyelid is affected. It is appropriate for outpatient notes, consults, or problem lists that clearly identify the condition. If the eyelid later becomes specified, code to the more precise option.
Do not use for
Do not use this code for systemic lupus without a documented discoid eyelid lesion. Do not assign it if the record specifies a different eye, a different eyelid, or only a nonspecific facial rash.
Coding tip
Check laterality and eyelid detail carefully; if the note names upper or lower eyelid, choose the more specific code.
