R25: ICD10 Code for Abnormal involuntary movements
R25 is the ICD10 code used for documenting Abnormal involuntary movements affecting movement, gait, coordination, and motor functions.

R25 refers to Abnormal involuntary movements, covering involuntary movements (like tremors, tics), walking or mobility issues, poor coordination, and other neuromuscular signs that may precede or accompany neurological diseases.
Symptoms
- Uncontrolled tremors or muscle jerks – Seen in abnormal involuntary movements (R25)
- Difficulty walking steadily or limping – Related to abnormalities of gait and mobility (R26)
- Clumsiness or impaired coordination – Associated with R27
- General neuromuscular weakness or reflex changes – Found under R29
Diagnosis
Diagnosis involves a neurological exam, gait analysis, electromyography (EMG), brain imaging (MRI/CT scans), and sometimes lab work to identify metabolic or degenerative causes.
ICD10 Code Usage
ICD10 code R25 is used to document motor control and coordination issues in clinical records, initiate further neurology referrals, and support symptom-based billing when no final diagnosis is yet made.
Related Codes
- R26 – Abnormalities of gait and mobility
- R27 – Other lack of coordination
- R29 – Other symptoms and signs involving the nervous and musculoskeletal systems
FAQs
Q1: What is ICD10 code R25?
A: It records Abnormal involuntary movements, which includes a range of abnormal movements, walking impairments, and neuromuscular signs.
Q2: Are all gait issues related to strokes?
A: No, gait issues may also result from musculoskeletal problems, neuropathies, Parkinson’s disease, or aging.
Q3: When are involuntary movements serious?
A: Persistent, worsening, or new involuntary movements should be evaluated to rule out neurological diseases.
Q4: Is poor coordination always neurological?
A: Often it is, but it can also be due to muscle weakness, medication effects, or balance disorders.
Q5: Can children have these symptoms?
A: Yes, motor development disorders in children may present similarly and need pediatric evaluation.
Conclusion
ICD10 code R25 ensures proper documentation of Abnormal involuntary movements, aiding in early detection, symptom tracking, and management of neuromuscular and movement disorders.
