ICD-10 Code H01.02 – Squamous blepharitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.02 – Squamous blepharitis
What it is
Squamous blepharitis is inflammation of the eyelid margins with scaling or crusting along the lashes. Use this code when the documentation specifically identifies squamous blepharitis.
Clinical signs
Typical findings include eyelid redness, irritation, itching, and flaky debris or crust at the lash line. Clinical features vary; refer to documentation.
When to use this code
Use H01.02 when the provider documents squamous blepharitis as the diagnosed eyelid condition. It may apply when notes describe chronic lid-margin inflammation with scale or crusting. If the record only says “blepharitis” without type, check documentation.
Do not use for
Do not use this code for unspecified blepharitis when the type is not stated. Do not use it for other eyelid disorders or infections unless the clinician clearly documents squamous blepharitis.
Coding tip
Confirm the blepharitis subtype in the assessment, not just in symptom notes.
