ICD-10 Code H01.023 – Squamous blepharitis right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.023 – Squamous blepharitis right eye, unspecified eyelid
What it is
H01.023 identifies squamous blepharitis affecting the right eye when the eyelid is not otherwise specified. Use it for inflammation of the eyelid margin with scaling or flaking on the right side.
Clinical signs
Typical findings include eyelid redness, irritation, crusting, and scales at the lash line. Clinical features vary; refer to documentation if the note does not clearly describe squamous changes or laterality.
When to use this code
Use this code when the provider documents squamous blepharitis limited to the right eye and does not specify upper or lower eyelid. It also fits follow-up visits when the diagnosis remains active and unchanged. Confirm laterality before assigning the code.
Do not use for
Do not use H01.023 if the record identifies the left eye, both eyes, or a different blepharitis type. Check documentation when the eyelid location is specified more precisely.
Coding tip
Always verify both laterality and eyelid detail; unspecified eyelid means you should code only what is documented.
