Other drug induced movement disorders
ICD-10 G25.79 is a billable code used to indicate a diagnosis of other drug induced movement disorders.
G25.79 refers to movement disorders that are induced by medications, particularly those affecting the dopaminergic system. These disorders can manifest as a variety of symptoms, including tremors, rigidity, bradykinesia, and abnormal postures. The most common culprits are antipsychotic medications, which can lead to extrapyramidal symptoms (EPS) resembling Parkinson's disease. Patients may experience acute dystonic reactions, akathisia, or tardive dyskinesia, which can significantly impact their quality of life. The pathophysiology involves alterations in dopamine pathways, particularly in the basal ganglia, leading to disrupted motor control. Accurate diagnosis requires a thorough medication history and clinical evaluation to differentiate between drug-induced movement disorders and primary movement disorders like Parkinson's disease. Treatment often involves adjusting the offending medication or using adjunctive therapies to manage symptoms.
Detailed neurological examination findings, medication history, and response to treatment.
Patients presenting with new-onset tremors after starting antipsychotic medications.
Neurologists should document the timeline of symptom onset in relation to medication changes.
Comprehensive psychiatric evaluation, including medication management and side effects.
Patients experiencing EPS after initiation of antipsychotic therapy.
Psychiatrists must clearly document the rationale for medication choices and any adjustments made.
Used when evaluating a patient with drug-induced movement disorders.
Detailed history, examination findings, and treatment plan.
Neurologists and psychiatrists should document the impact of medication on symptoms.
Common medications include antipsychotics (e.g., haloperidol, risperidone), antiemetics (e.g., metoclopramide), and certain antidepressants. It's crucial to review the patient's medication history to identify potential causes.
