Understanding Familial Parkinson Disease

Familial Parkinson disease, identified by the ICD-11 code 8A00.01, is a specific subtype of Parkinsonism. Parkinsonism itself is a clinical syndrome characterised by a combination of symptoms including rest tremor, muscular rigidity, akinesia or bradykinesia (slowness of movement), and postural disturbances such as shuffling gait and a flexed posture. A diagnosis of Parkinsonism typically requires bradykinesia along with at least one other cardinal feature. Familial Parkinson disease specifically points to cases where a genetic predisposition plays a significant role in the development of these neurodegenerative symptoms.

Genetic Factors and Parkinsonism

The designation "Familial Parkinson disease" highlights the hereditary nature of this condition. While most cases of Parkinson's disease are considered sporadic, a notable subset is linked to inherited genetic factors. This means that individuals with a family history of the condition may have an increased risk due to specific gene mutations passed down through generations. Understanding these genetic links is crucial for comprehensive diagnosis and potential family counselling.

Diagnostic Pathways for Parkinsonism

The diagnosis of Parkinsonism, including Familial Parkinson disease (ICD-11 code 8A00.01), is primarily based on clinical evaluation. Healthcare professionals assess for the presence of key motor symptoms such as resting tremor, rigidity, bradykinesia, and postural instability. A detailed patient history, including a thorough family history of neurological disorders, is essential for identifying potential familial cases. While there isn't a single definitive test, diagnostic processes may involve neurological examinations and sometimes imaging or other investigations to rule out other conditions that can mimic Parkinsonism.

Documentation and Coding Considerations

For accurate medical records and billing, the specific ICD-11 code 8A00.01 should be used for Familial Parkinson disease. This code falls under the broader category of Parkinsonism (8A00) within the ICD-11 classification system. Proper documentation is key for healthcare providers, ensuring that the familial aspect of the condition is noted. Using the correct ICD-11 code for Familial Parkinson disease supports precise reporting for statistical purposes, clinical research, and reimbursement processes. Medical coding for 8A00.01 requires careful attention to the diagnostic details provided by the clinician.

Alternative Names for Familial Parkinson Disease

Familial Parkinson disease (ICD-11 code 8A00.01) may also be referred to by other terms that reflect its underlying cause or characteristics. Common alternative names include Hereditary Parkinson disease or Genetic Parkinson disease. These synonyms underscore the inherited nature of the condition, distinguishing it from sporadic forms of Parkinsonism. It is important to recognise these variations when searching for information or documenting patient care.

Recognising When to Seek Medical Attention

Individuals experiencing persistent symptoms such as a tremor that occurs at rest, noticeable stiffness in the limbs, a general slowness of movement, or difficulties with balance and coordination should seek prompt medical advice. If there is a known family history of Parkinson disease or similar neurological conditions, consulting a healthcare professional becomes even more important. Early recognition and diagnosis of Familial Parkinson disease (ICD-11 code 8A00.01) can facilitate timely management and support.
