Other group 2 peroxisomal disorders

This code signifies a rare, inherited metabolic disorder affecting peroxisome function, specifically within the group 2 classification. These disorders involve defects in the synthesis or assembly of peroxisomal proteins, leading to the accumulation of very long-chain fatty acids and other toxic metabolites in various tissues. Clinical manifestations are diverse and can include neurological impairment, developmental delay, and organ dysfunction.

Apply this code when documentation specifies a diagnosis of a group 2 peroxisomal disorder that is not otherwise classified by a more specific ICD-10-CM code (e.g., Zellweger syndrome, neonatal adrenoleukodystrophy). Supporting documentation should include genetic testing results, enzyme assays, or clinical findings consistent with a peroxisomal biogenesis disorder.

• Ensure the physician's documentation clearly states "group 2 peroxisomal disorder" or a similar non-specific term within this category.
• Avoid using this code if a more specific code within E71.5 (e.g., E71.51 for Zellweger syndrome) is applicable.
• Always review the medical record for any associated neurological, developmental, or organ-specific manifestations that may require additional coding.
