Cerebral lipidoses

This code represents a group of rare, inherited metabolic disorders characterized by the abnormal accumulation of lipids (fats) in the brain and other parts of the nervous system. These lipid storage diseases lead to progressive neurological dysfunction due to the buildup of these substances within cells, impairing their normal function.

Use this code when documentation clearly indicates a diagnosis of a cerebral lipidosis, such as Tay-Sachs disease, Gaucher disease (neuropathic forms), Niemann-Pick disease, or Krabbe disease, affecting the central nervous system. This code is appropriate for patients presenting with neurological symptoms attributable to these lipid storage disorders.

• Always review the medical record for specific type of lipidosis to determine if a more specific ICD-9-CM code is available within the 330 category.
• Code any associated neurological manifestations (e.g., seizures, developmental delay) separately as secondary diagnoses.
• Ensure documentation specifies the cerebral involvement, as some lipidoses may primarily affect other organ systems.
