ICD-10 Code H01.015 – Ulcerative blepharitis left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.015 – Ulcerative blepharitis left lower eyelid
What it is
H01.015 identifies ulcerative blepharitis affecting the left lower eyelid. It refers to inflammation of the eyelid margin with ulceration, limited to that specific side and location.
Clinical signs
Typical findings include eyelid margin redness, crusting, scaling, and small ulcerations at the lash line. Clinical features vary; refer to documentation for laterality and whether the lower eyelid is specifically involved.
When to use this code
Use this code when the record clearly states ulcerative blepharitis of the left lower eyelid. You should also use it when the provider documents localized lid-margin inflammation with ulceration on that eyelid and no broader eyelid site is specified.
Do not use for
Do not use H01.015 for blepharitis of another eyelid, both eyelids, or unspecified laterality. Do not use it if the note describes a different eye disorder without ulcerative blepharitis; check documentation.
Coding tip
Verify both laterality and eyelid location in the chart before assigning H01.015.
