ICD-10 Code H01.01A – Ulcerative blepharitis right eye, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.01A – Ulcerative blepharitis right eye, upper and lower eyelids
What it is
This code identifies ulcerative inflammation of the right eyelid margins affecting both the upper and lower lids. Use it when the record specifies the right eye and ulcerative blepharitis.
Clinical signs
Typical findings include eyelid-margin redness, crusting, and ulceration at the lashes. Patients may report irritation, burning, or foreign-body sensation; clinical features vary, so refer to documentation.
When to use this code
Use H01.01A when the provider documents ulcerative blepharitis limited to the right upper and lower eyelids. It is appropriate for confirmed laterality and lid involvement in the assessment, problem list, or encounter note. Check documentation if the record does not clearly specify ulcerative disease.
Do not use for
Do not use this code for blepharitis without ulceration, unspecified laterality, or left-sided disease. If the note only says “blepharitis,” check documentation.
Coding tip
Match both laterality and lid involvement exactly; H01.01A is specific to the right upper and lower eyelids.
