Parkinson's Disease: A Neurological Disorder

Understanding Parkinson's Disease

Parkinson's disease is a progressive neurological disorder that affects nerve cells (neurons) in a part of the brain that controls muscle movement, leading to tremors, rigidity, and impaired coordination.

ICD-10-CM Coding for Parkinson's Disease

G20A1 is the billablespecific ICD-10-CM code used to indicate a diagnosis of Parkinson's disease for reimbursement purposes.

Impact and Epidemiology

Parkinson's disease affects several regions of the brain, particularly an area called the substantia nigra. Unlike other neurological disorders such as migraine and epilepsy, there is only one ICD-10-CM code (G20) specifically for Parkinson's disease.
