ICD-10 Code H01.025 – Squamous blepharitis left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.025 – Squamous blepharitis left lower eyelid
What it is
H01.025 identifies squamous blepharitis affecting the left lower eyelid. Use it when the record specifies flaky, scaly inflammation of that eyelid margin.
Clinical signs
Typical findings include eyelid margin redness, scaling, and crusting around the lashes. Patients may report irritation, burning, or a foreign-body sensation; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents squamous blepharitis limited to the left lower eyelid. It is appropriate for office, outpatient, or follow-up visits when laterality and location are clearly stated. Check documentation if the note only says blepharitis without eyelid detail.
Do not use for
Do not use it for blepharitis of another eyelid, both eyelids, or unspecified laterality. It is also wrong if the record describes a different eyelid disorder or only general eye irritation.
Coding tip
Confirm both laterality and eyelid location in the provider note before assigning H01.025.
