ICD-10 Code H01.022 – Squamous blepharitis right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.022 – Squamous blepharitis right lower eyelid
What it is
H01.022 identifies squamous blepharitis affecting the right lower eyelid. It is inflammation of the eyelid margin with scaling or flaking at the lashes.
Clinical signs
Typical findings include eyelid margin redness, crusting, and fine scales around the eyelashes. Clinical features vary; refer to documentation if the note does not clearly specify the right lower eyelid.
When to use this code
Use this code when the provider documents squamous blepharitis limited to the right lower eyelid. It also fits notes describing eyelid-margin inflammation with scaling on that side. If laterality or eyelid location is unclear, check documentation before coding.
Do not use for
Do not use it for blepharitis of another eyelid, bilateral disease, or a different type of blepharitis. If the record only says “blepharitis” without location or type, check documentation.
Coding tip
Match both laterality and eyelid level exactly; H01.022 is specific to the right lower eyelid.
