ICD-10 Code H01.024 – Squamous blepharitis left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.024 – Squamous blepharitis left upper eyelid
What it is
H01.024 identifies squamous blepharitis affecting the left upper eyelid. It means inflammation of the eyelid margin with flaky, scale-like debris.
Clinical signs
Typical findings include redness, irritation, itching, crusting, and visible scaling along the eyelid margin. Clinical features vary; refer to documentation if laterality or eyelid location is unclear.
When to use this code
Use this code when the record specifically documents squamous blepharitis of the left upper eyelid. Apply it when the provider identifies the condition by laterality and eyelid, not just general blepharitis.
If the note only says blepharitis without location, check documentation before assigning this code. You should also confirm that the left upper eyelid is the site being treated or assessed.
Do not use for
Do not use H01.024 for blepharitis of another eyelid, another eye, or unspecified blepharitis. Check documentation if the record describes a different eyelid disorder.
Coding tip
Code laterality and eyelid precisely; this diagnosis is not interchangeable with unspecified blepharitis.
