R25 is a non-billable ICD-10-CM category code for abnormal involuntary movements, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R25.0, R25.1, R25.2, and R25.3. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R25Overview

Is R25 (Abnormal involuntary movements) a billable code?

No. This is a category header that groups the codes for abnormal involuntary movements, and headers cannot be submitted on claims. Claims for abnormal involuntary movements need a more specific code from this category, such as R25.0, R25.1, and R25.2.

Can R25 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the abnormal involuntary movements is established, that condition takes the principal position instead.
