Code Description

ICD-10 G11.1 is a billable code used to indicate a diagnosis of early-onset cerebellar ataxia.

Key Diagnostic Point:

Early-onset cerebellar ataxia refers to a group of hereditary disorders characterized by the progressive degeneration of the cerebellum, leading to impaired coordination and balance. This condition typically manifests in childhood or adolescence and is often associated with genetic mutations that affect neuronal function. The cerebellum plays a crucial role in motor control, and its dysfunction can result in symptoms such as gait disturbances, tremors, and difficulties with fine motor tasks. Various forms of early-onset cerebellar ataxia exist, including spinocerebellar ataxias (SCAs), which are a subset of hereditary ataxias caused by genetic mutations. These conditions can be inherited in an autosomal dominant or recessive manner. Diagnosis is primarily clinical, supported by genetic testing to identify specific mutations. Management focuses on symptomatic relief and supportive therapies, as there is currently no cure for these degenerative conditions. Understanding the hereditary nature of early-onset cerebellar ataxia is essential for genetic counseling and family planning.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of hereditary forms with different genetic mutations
  • Need for genetic testing to confirm diagnosis
  • Differentiation from other ataxias and motor neuron diseases
  • Potential for overlapping symptoms with other neurological disorders

Audit Risk Factors

  • Inadequate documentation of genetic testing results
  • Failure to document family history of ataxia
  • Misclassification of ataxia type
  • Lack of detailed clinical notes on symptom progression
