Schilder's disease

This code identifies Schilder's disease, a rare, progressive demyelinating disorder primarily affecting the white matter of the brain. It is characterized by large, bilateral, and often symmetrical demyelinating lesions, leading to neurological deficits. This condition is considered a variant of multiple sclerosis or a distinct leukodystrophy.

Assign this code when documentation explicitly states a diagnosis of Schilder's disease. This diagnosis is typically made based on clinical presentation, neuroimaging findings (e.g., MRI showing characteristic white matter lesions), and exclusion of other demyelinating conditions. Supporting documentation should include neurologist notes, imaging reports, and pathology if a biopsy was performed.

• Differentiate carefully from other demyelinating diseases like multiple sclerosis (MS) or adrenoleukodystrophy, as Schilder's has specific diagnostic criteria.
• Ensure documentation specifies "Schilder's disease" and not just a generic demyelinating disorder of the central nervous system.
• Consider sequencing this code as the primary diagnosis when it is the main reason for the encounter or hospitalization.
