ICD-10 Code H01.016 – Ulcerative blepharitis left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.016 – Ulcerative blepharitis left eye, unspecified eyelid
What it is
H01.016 identifies ulcerative blepharitis affecting the left eye when the eyelid is not further specified. It describes an inflammatory eyelid disorder with ulceration at the lid margin.
Clinical signs
Typical findings include eyelid redness, crusting, and irritation along the lid margin. Clinical features vary; refer to documentation for whether ulceration, scaling, or tenderness is recorded.
When to use this code
Use this code when the provider documents ulcerative blepharitis of the left eye and does not specify upper or lower eyelid. It is also appropriate when the note clearly identifies left-sided involvement but leaves the eyelid unspecified. Check documentation if the record mentions both eyelids or a different laterality.
Do not use for
Do not use H01.016 for blepharitis without ulceration or when the documentation identifies the right eye. If the eyelid is specified as upper or lower, code that more precise option instead.
Coding tip
Confirm laterality and eyelid specificity in the assessment before assigning H01.016.
