ICD-10 Code H01.02B – Squamous blepharitis left eye, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.02B – Squamous blepharitis left eye, upper and lower eyelids
What it is
This code identifies squamous blepharitis affecting the left upper and lower eyelids. It refers to inflammation along the eyelid margins with scaling or debris.
Clinical signs
Typical findings include eyelid redness, irritation, crusting, and flaky or scaly material at the lash line. Clinical features vary; refer to documentation.
When to use this code
Use H01.02B when the record clearly documents squamous blepharitis in the left eye involving both the upper and lower eyelids. You should also use it when the provider specifies blepharitis type and laterality without ambiguity. Check documentation if the note does not clearly identify both lids.
Do not use for
Do not use this code for blepharitis of the right eye, unspecified eyelids, or non-squamous blepharitis. If the laterality or eyelid involvement is not stated, check documentation.
Coding tip
Confirm both laterality and eyelid location in the assessment before assigning H01.02B.
