ICD-10 Code H01.011 – Ulcerative blepharitis right upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.011 – Ulcerative blepharitis right upper eyelid
What it is
H01.011 identifies ulcerative blepharitis affecting the right upper eyelid. It describes inflammation of the eyelid margin with ulceration, limited to that side and location.
Clinical signs
Typical findings include eyelid margin redness, crusting, and irritation, sometimes with scaling or ulceration at the lash line. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents ulcerative blepharitis specifically in the right upper eyelid. It is appropriate for laterality-specific charting and problem lists when that exact site is confirmed.
If the note only says blepharitis without ulceration or laterality, check documentation before assigning H01.011. You should code the documented eyelid and side, not infer them.
Do not use for
Do not use H01.011 for blepharitis of another eyelid, both eyelids, or nonspecific blepharitis without ulceration. Check documentation if the record does not clearly identify the right upper eyelid.
Coding tip
Match the code to both the ulcerative type and the exact eyelid laterality; if either element is missing, verify the provider note.
