ICD-10 Code G24.5 – Blepharospasm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G24.5 – Blepharospasm
What it is
G24.5 identifies blepharospasm, a focal dystonia causing involuntary, repeated eyelid muscle contractions. It may lead to excessive blinking or brief forced eye closure.
Clinical signs
Typical findings include intermittent or sustained eyelid spasms, increased blinking, and difficulty keeping the eyes open. Clinical features vary; refer to documentation.
When to use this code
Use G24.5 when the provider documents blepharospasm as the diagnosed condition. It is appropriate for cases described as involuntary eyelid spasms or focal dystonia affecting the eyelids. Check documentation if the note only mentions nonspecific eye twitching.
Do not use for
Do not use this code for general facial twitching, eyelid myokymia, or spasm from irritation without a blepharospasm diagnosis. Check documentation when the cause is unclear.
Coding tip
Code only when the record clearly names blepharospasm; otherwise, query for specificity.
