ICD-10 Code H02.514 – Abnormal innervation syndrome left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.514 – Abnormal innervation syndrome left upper eyelid
What it is
H02.514 identifies abnormal nerve supply affecting the left upper eyelid. Use it when the chart documents a congenital or acquired innervation problem rather than a general eyelid droop or spasm.
Clinical signs
Findings may include abnormal eyelid movement, position, or coordination on the left upper lid. Clinical features vary; refer to documentation for the specific pattern and laterality.
When to use this code
Use this code when the provider explicitly documents abnormal innervation syndrome of the left upper eyelid. It may fit notes describing misdirected, absent, or otherwise abnormal eyelid innervation affecting function or appearance. Check documentation if the record only says ptosis, blepharospasm, or eyelid weakness.
Do not use for
Do not use this code for unspecified eyelid disorders or for left upper eyelid conditions without an innervation abnormality. If the diagnosis is different, such as simple ptosis, code the documented condition instead.
Coding tip
Verify both the side and the word “innervation” in the provider’s diagnosis before assigning H02.514.
