ICD-10 Code H02.515 – Abnormal innervation syndrome left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.515 – Abnormal innervation syndrome left lower eyelid
What it is
This code identifies abnormal nerve supply affecting the left lower eyelid. It is used when the eyelid’s movement or position is altered because of an innervation problem.
Clinical signs
Findings may include eyelid malposition, abnormal blinking, or involuntary eyelid movement on the left lower lid. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents abnormal innervation syndrome of the left lower eyelid. It may apply after neurologic, congenital, or postsurgical evaluation if the provider names this condition. Do not infer laterality or diagnosis from symptoms alone.
Do not use for
Do not use it for nonspecific eyelid spasm, ptosis, or general eyelid weakness without documented abnormal innervation. Check documentation if the chart does not clearly identify the left lower eyelid.
Coding tip
Verify both laterality and the exact provider wording before assigning H02.515.
