Regarded as a serious nervous system disorder, Parkinson's disease (PD) causes progressive damage of the brain over many years. The condition leads to progressive deterioration of motor function due to loss of dopamine-producing brain cells. The exact cause of Parkinson’s disease is unknown. However, several factors like genes, environmental triggers, and the presence of Lewy bodies in brain cells appear to play an important role. Although most people with PD first develop the disease after the age of 60 years, about 5-10 percent people experience onset before the age of 50 years. Early-onset forms of Parkinson’s are often (but not always) inherited, and some forms have been linked to specific gene mutations. Although this neurological condition can’t be fully cured, medications can significantly reduce or improve the severity of symptoms. Billing and coding for PD can be challenging. Relying on the services of a reputable medical coding company can help in precise documentation of this neurodegenerative disorder.

Symptoms, Diagnosis and Treatment of PD The signs and symptoms of Parkinson’s disease can vary from one person to another. In the early stages, patients experience mild symptoms that may go unnoticed. In most cases, symptoms often begin on one side of the body and tend to affect both sides. The condition begins gradually as a noticeable tremor in just one hand. On the other hand, it can also cause stiffness or slowing of movement. Other related symptoms include – loss of automatic movements and writing changes, speech changes, impaired posture and balance, rigid muscles and slowed movement (bradykinesia).

There is no specific test that helps diagnose Parkinson’s disease. Initial diagnosis of PD involves an evaluation of medical history and signs and symptoms. A detailed neurological and physical examination may also be performed. Neurologists may perform a specific single-photon emission computerized tomography (SPECT) scan called a dopamine transporter scan (DaTscan). In addition, imaging tests (like MRI, ultrasound of the brain, and PET scans) and other blood tests may also be performed to rule out symptoms that cause these disorders. Treatment modalities include medications that help control problems

with walking, movement and tremor. For people with PD who do not respond well to medications, neurologists may recommend deep brain stimulation – a surgical procedure where a physician implants electrodes into the brain and connects them to a small electrical device implanted in the chest. Other therapies - physical, occupational, and speech therapies may also be advised to reduce tremors and other voice disorders.

ICD-10 Codes for Parkinson’s Disease (PD) Neurologists who diagnose PD and administer treatment procedures must correctly document the same using the right medical codes. Medical billing services provided by professional providers ensure that the correct medical codes are reported on the claims.

ICD-10 codes for diagnosing PD include –

•

G20 Parkinson's disease

•

G21 Secondary parkinsonism

•

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

•

G21.4 Vascular parkinsonism

•

G21.8 Other secondary parkinsonism

•

G21.9 Secondary parkinsonism, unspecified

Neurology medical billing can be challenging. For accurate and timely medical billing and claims submission, healthcare practices can outsource their billing and coding tasks to a reliable medical billing coding company that provides the services of AAPC-certified coding specialists.
