Parkinson's Disease ICD-10-CM Codes

What ICD-10 Codes Are Used for Parkinson's Disease?

To accurately document and diagnose Parkinson's Disease, it's essential to be aware of the relevant Parkinson's Disease ICD codes. Here are some prominent codes:

• G20: Parkinson's disease
• G21.0: Malignant neuroleptic syndrome
• G21.1: Other drug-induced secondary Parkinsonism
• G21.11: Neuroleptic-induced Parkinsonism
• G21.19: Other drug-induced secondary Parkinsonism
• G21.2: Secondary Parkinsonism due to other external agents
• G21.3: Postencephalitic Parkinsonism
• G21.8: Other secondary Parkinsonism
• G21.9: Secondary Parkinsonism, unspecified

These Parkinson's Disease ICD codes assist in detailing patient histories and streamlining the billing process.

Clinical Information

Parkinson's disease is a neurodegenerative disorder that affects movement. Vital clinical highlights include:

• Generally develops after age 60 but can occur earlier.
• Symptoms include tremors, rigidity, and bradykinesia.
• Result of a reduction in dopamine-producing neurons in the brain.
• The exact cause is unknown, but genetic and environmental factors play a role.
• No cure currently exists, but symptoms can be managed with medications and therapies.

Synonyms Include:

• Parkinsonism
• Idiopathic Parkinson's
• Paralysis agitans
• Shaking palsy
• Parkinsonian syndrome
