ICD-10 Code H01.019 – Ulcerative blepharitis unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.019 – Ulcerative blepharitis unspecified eye, unspecified eyelid
What it is
This code identifies ulcerative inflammation of the eyelid margins when the eye and eyelid side are not specified. It usually reflects crusting, irritation, and small ulcers along the lid edge.
Clinical signs
Typical findings include red, swollen eyelid margins, scaling, crusting, and lash involvement. Ulceration at the lid edge may be present; clinical features vary, so refer to documentation.
When to use this code
Use H01.019 when the record documents ulcerative blepharitis but does not identify the affected eye or eyelid. It also fits when laterality is unclear or not recorded. If the note specifies a different eyelid disorder, code that condition instead.
Do not use for
Do not use this code for nonulcerative blepharitis, conjunctivitis, or nonspecific eye irritation. If documentation names a more specific eye or eyelid laterality, check documentation and code the exact diagnosis.
Coding tip
Always verify laterality and whether the condition is ulcerative before assigning H01.019.
