2025 ICD-10-CM code G26

Extrapyramidal and movement disorders in diseases classified elsewhere. This code should be used in conjunction with a code for the underlying disease.

Always code the underlying disease first.G26 is a manifestation code, not a primary diagnosis code.

Medical necessity is established by the diagnosis and treatment of the underlying condition causing the extrapyramidal and movement disorder.

Clinicians diagnose these conditions based on medical history, family history, symptoms, physical and neurological examination, and sometimes lab tests and imaging studies. Treatment may involve medication, therapies, or even surgery like deep brain stimulation.

In simple words: This code refers to abnormal, involuntary movements like tremors, tics, or spasms caused by another medical condition.The underlying condition needs to be diagnosed and coded separately as well.

Extrapyramidal and movement disorders in diseases classified elsewhere refer to involuntary and repetitive abnormal movements occurring secondary to an underlying disease or pathological condition. The underlying disease should be coded first.

Example 1: A patient with Parkinson's disease (coded first) experiences tremors. G26 would be used as a secondary code to specify the movement disorder manifestation., A patient with multiple sclerosis (coded first) develops intention tremors.G26 is used to indicate the associated movement disorder., A patient on antipsychotic medication develops tardive dyskinesia. The underlying cause (medication effect) is coded, followed by G26 for the movement disorder.

Documentation should clearly link the movement disorder to the underlying condition and specify the type of movement disorder observed.
