ICD-10 Code H01.013 – Ulcerative blepharitis right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.013 – Ulcerative blepharitis right eye, unspecified eyelid
What it is
H01.013 identifies ulcerative blepharitis affecting the right eye when the eyelid is not further specified. It refers to inflammation of the eyelid margins with ulceration, limited to the right side.
Clinical signs
Typical findings include red, irritated eyelid margins, crusting, scaling, and small ulcerations at the lash line. Clinical features vary; refer to documentation for laterality and which eyelid is involved.
When to use this code
Use this code when the record clearly states ulcerative blepharitis of the right eye and does not identify a specific eyelid. It fits outpatient, specialist, or problem-list documentation that names the condition without additional eyelid detail. If the note specifies a particular eyelid, code that more specific option instead.
Do not use for
Do not use it for blepharitis without ulceration, left-eye disease, or unspecified eye laterality. Check documentation if the chart only mentions eyelid irritation or another eyelid disorder.
Coding tip
Verify both laterality and whether the eyelid is unspecified before assigning H01.013.
