ICD-10 Code H02.512 – Abnormal innervation syndrome right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.512 – Abnormal innervation syndrome right lower eyelid
What it is
H02.512 identifies abnormal nerve control affecting the right lower eyelid. Use it when documentation states this specific eyelid innervation disorder on the right side.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal eyelid movement, lid retraction, or other neuromuscular eyelid dysfunction noted on examination.
When to use this code
Use this code when the clinician documents abnormal innervation syndrome limited to the right lower eyelid. It is appropriate for cases where the diagnosis is explicit and laterality is confirmed. If the note only describes eyelid weakness or spasm without this diagnosis, check documentation.
Do not use for
Do not use it for unspecified eyelid disorders, left-sided disease, or general facial nerve problems without right lower eyelid involvement. Check documentation if the chart uses a different named eyelid condition.
Coding tip
Verify laterality and exact wording in the provider note before assigning H02.512.
