ICD-10 Code H01.012 – Ulcerative blepharitis right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.012 – Ulcerative blepharitis right lower eyelid
What it is
H01.012 identifies ulcerative blepharitis affecting the right lower eyelid. It means inflammation of the eyelid margin with ulceration, limited to that specific eyelid.
Clinical signs
Typical findings include eyelid margin redness, crusting, scaling, and small ulcers or erosions at the lash line. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents ulcerative blepharitis of the right lower eyelid specifically. It is appropriate for office visits, follow-up care, or problem list entries tied to that exact site. If the note only says blepharitis without laterality or lid location, Check documentation.
Do not use for
Do not use H01.012 for blepharitis of another eyelid or for unspecified blepharitis. Avoid it when the record describes a different eyelid disorder without ulceration.
Coding tip
Match laterality and eyelid location exactly; if either is missing, query the provider before assigning H01.012.
