Secondary parkinsonism
Chapter 6:Diseases of the nervous system
ICD-10 G21 is a billable code used to indicate a diagnosis of secondary parkinsonism.
Secondary parkinsonism refers to a group of movement disorders that exhibit symptoms similar to Parkinson's disease but are caused by other underlying conditions or factors. Unlike primary Parkinson's disease, which is idiopathic, secondary parkinsonism can result from various etiologies including neurodegenerative diseases, vascular issues, infections, metabolic disorders, and exposure to certain medications, particularly dopaminergic agents. Symptoms typically include bradykinesia, rigidity, and tremors, which can significantly impact a patient's quality of life. The diagnosis of secondary parkinsonism requires a thorough clinical evaluation, including a detailed patient history, neurological examination, and sometimes imaging studies to identify the underlying cause. Treatment strategies often focus on managing the symptoms and addressing the root cause, which may involve adjusting or discontinuing medications, physical therapy, or other interventions. Understanding the nuances of secondary parkinsonism is crucial for accurate coding and appropriate patient management.
Detailed neurological examination findings, history of symptoms, and any relevant imaging or lab results.
Patients presenting with tremors, rigidity, and bradykinesia after starting new medications or with a history of stroke.
Ensure clear documentation of the timeline of symptom onset in relation to medication use or other potential causes.
Comprehensive assessment of functional status, medication review, and evaluation of comorbid conditions.
Older adults presenting with movement disorders after polypharmacy or with multiple chronic conditions.
Focus on the impact of secondary parkinsonism on daily living activities and overall health.
Used for follow-up visits for patients with secondary parkinsonism.
Document the patient's history, examination findings, and treatment plan.
Neurologists should focus on detailed neurological assessments.
Primary parkinsonism, or Parkinson's disease, is idiopathic and has no identifiable cause, while secondary parkinsonism is caused by other medical conditions or factors, such as medications or metabolic disorders.
