R25-R29: Symptoms and signs involving the nervous and musculoskeletal systems

R25: Abnormal involuntary movements

Abnormal involuntary movements, classified under the ICD-10 code group range: R25, encompass a set of conditions where the patient experiences involuntary (uncontrolled) movements. These irregular movements can present as a fluttering (tremors), jerking (tics) or sustained muscle contractions (dystonia), among other types, and can affect different parts of the body such as the limbs, face or torso. These symptoms are often the result of a range of underlying neurological conditions, which might include Parkinson's disease, Huntington's disease, or certain medications triggering side effects. The presentation of abnormal involuntary movements can vary widely in terms of the area of body affected, the type of movement, and the speed and severity of disease progression. It is important to note that while these symptoms can be inconvenient and impact quality of life, they do not typically signify a serious, life-threatening condition. They predominantly signal an issue within the nervous system that requires medical evaluation for accurate diagnosis and treatment.
