ICD-10 Code H01.003 – Unspecified blepharitis right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.003 – Unspecified blepharitis right eye, unspecified eyelid
What it is
H01.003 identifies blepharitis affecting the right eye when the eyelid is not further specified. It means the chart documents eyelid inflammation, but not the exact eyelid location or type.
Clinical signs
Common findings include eyelid redness, irritation, crusting, itching, burning, and lid-margin scaling. Clinical features vary; refer to documentation if the record does not clearly describe the eyelid involved.
When to use this code
Use this code when the provider documents blepharitis in the right eye and does not specify upper, lower, or both eyelids. It also fits cases where the note confirms blepharitis but leaves eyelid detail incomplete. If laterality or eyelid location is clearer, code that more specific option instead.
Do not use for
Do not use this code for left eye blepharitis, bilateral blepharitis, or cases that specify a different eyelid laterality. Check documentation if the note describes another eyelid disorder without confirming blepharitis.
Coding tip
When the record says only “right blepharitis,” confirm whether the eyelid is unspecified before assigning H01.003.
