ICD-10 Code G24.8 – Other dystonia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G24.8 – Other dystonia
What it is
G24.8 identifies dystonia that does not fit a more specific ICD-10-CM category. Use it for involuntary, sustained, or intermittent muscle contractions causing abnormal postures or twisting movements when the documentation supports “other dystonia.”
Clinical signs
Clinical features vary; refer to documentation. Typical findings include abnormal posturing, repetitive twisting, or patterned movements that may affect the neck, limbs, face, or trunk.
When to use this code
Use G24.8 when the clinician documents dystonia but does not name a more specific type, such as focal, generalized, or drug-induced dystonia. It also applies when the record clearly states “other dystonia” or describes a dystonic disorder not classified elsewhere.
Review the note for a more specific diagnosis before assigning this code. If the cause or subtype is documented elsewhere, code that condition instead.
Do not use for
Do not use G24.8 for drug-induced dystonia, essential tremor, or other movement disorders with a different code. Check documentation if the record provides a specific dystonia subtype.
Coding tip
Code the most specific dystonia documented; use G24.8 only when the provider’s wording supports an unspecified “other” dystonia category.
