ICD-10 Code G25.83 – Benign shuddering attacks (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.83 – Benign shuddering attacks
What it is
G25.83 identifies benign shuddering attacks, brief involuntary episodes of rapid shivering or tremulous movements. They are typically non-epileptic and self-limited, so you should code the documented condition rather than a seizure disorder.
Clinical signs
Episodes usually involve sudden shuddering, trembling, or stiffening without loss of consciousness. Clinical features vary; refer to documentation, especially to distinguish them from seizures or other movement disorders.
When to use this code
Use this code when the record explicitly documents benign shuddering attacks or a confirmed equivalent term. It is appropriate for outpatient, inpatient, or specialty notes when the clinician has ruled out seizure activity and documented the diagnosis. If the chart is unclear, check documentation.
Do not use for
Do not use G25.83 for epilepsy, convulsions, or unspecified tremor unless the provider documents benign shuddering attacks. Avoid using it when the movements are not clearly characterized and the final diagnosis is still uncertain.
Coding tip
Code only when the provider names the condition; otherwise, query for clarification before assigning G25.83.
