ICD-10 Code H01.02A – Squamous blepharitis right eye, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.02A – Squamous blepharitis right eye, upper and lower eyelids
What it is
This code identifies squamous blepharitis affecting both the upper and lower eyelids of the right eye. It refers to inflammation along the eyelid margins with scaling or crusting.
Clinical signs
Typical findings include eyelid margin redness, flaking, and adherent scales at the lashes. Patients may report irritation, burning, itching, or a gritty sensation; clinical features vary, so refer to documentation.
When to use this code
Use H01.02A when the provider documents squamous blepharitis limited to the right eye and involving both upper and lower eyelids. Choose this code when laterality and eyelid involvement are clearly stated in the record.
If the note only says blepharitis without laterality or specifies a different eye, do not assume H01.02A. Check documentation for the exact site and whether the condition is squamous.
Do not use for
Do not use this code for blepharitis of the left eye, both eyes, or unspecified laterality. Also avoid it when the record describes a different eyelid disorder or the diagnosis is not documented as squamous blepharitis.
Coding tip
Verify both laterality and eyelid involvement in the provider note before assigning H01.02A.
