Childhood cerebral X-linked adrenoleukodystrophy

This code identifies a severe, progressive neurodegenerative disorder affecting young males, characterized by demyelination in the brain and adrenal insufficiency. It is an X-linked genetic condition leading to the accumulation of very long-chain fatty acids (VLCFAs) in tissues. The childhood cerebral form typically presents between ages 4 and 8 with behavioral changes, vision/hearing loss, and motor deficits.

Use this code for patients definitively diagnosed with the childhood cerebral form of X-linked adrenoleukodystrophy (X-ALD). Documentation should clearly state the specific type of adrenoleukodystrophy and the patient's age of onset or current presentation aligning with the childhood cerebral phenotype. Genetic testing results confirming the ABCD1 gene mutation, along with clinical findings, support its use.

• Differentiate from other forms of adrenoleukodystrophy (e.g., adolescent, adult-onset, adrenomyeloneuropathy) which have distinct codes.
• Ensure documentation specifies "childhood cerebral" to avoid confusion with other X-ALD phenotypes.
• Code any associated neurological manifestations (e.g., seizures, spasticity) or adrenal insufficiency separately.
