ICD-10 Code H01.002 – Unspecified blepharitis right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.002 – Unspecified blepharitis right lower eyelid
What it is
This code identifies blepharitis affecting the right lower eyelid when the type is not specified. It refers to inflammation of the eyelid margin, with no documented cause or subtype.
Clinical signs
Typical findings include eyelid redness, irritation, crusting, itching, or a burning sensation along the lid margin. Clinical features vary; refer to documentation.
When to use this code
Use H01.002 when the record clearly states blepharitis of the right lower eyelid and does not identify anterior, posterior, or other specified type. It is appropriate for outpatient, inpatient, or specialist notes when laterality and location are documented. Check documentation if the note is vague or if both eyelids are involved.
Do not use for
Do not use this code if the chart specifies a different eyelid, both eyelids, or a more specific blepharitis type. Do not assign it when the diagnosis is only eyelid irritation without documented blepharitis.
Coding tip
Confirm laterality and eyelid location in the assessment before assigning H01.002.
