ICD-10 Code H02.513 – Abnormal innervation syndrome right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.513 – Abnormal innervation syndrome right eye, unspecified eyelid
What it is
This code identifies abnormal nerve-related eyelid movement or positioning affecting the right eye, with the eyelid type not specified. Use it when documentation describes an innervation disorder of the right eyelid without a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. You may see involuntary eyelid movement, abnormal lid position, or signs of impaired eyelid control on the right side.
When to use this code
Use H02.513 when the provider documents abnormal innervation syndrome involving the right eye and does not specify the eyelid subtype. It may also fit when the record confirms a nerve-related eyelid disorder but lacks enough detail for a more specific code. Check documentation if laterality or eyelid type is unclear.
Do not use for
Do not use this code for generalized blepharospasm, ptosis without abnormal innervation, or eyelid disorders that are better described by another diagnosis. If the chart lacks right-eye laterality, check documentation.
Coding tip
Verify both laterality and the “unspecified eyelid” wording before assigning H02.513.
