Other peroxisomal disorders

This code represents a rare group of inherited metabolic disorders characterized by defects in peroxisome biogenesis or function, leading to the accumulation of very long-chain fatty acids and other toxic metabolites. These disorders can affect multiple organ systems, including the brain, liver, and kidneys, with varying clinical presentations and severity.

Use this code for peroxisomal disorders that do not have a more specific ICD-10-CM code available, such as Zellweger syndrome (E71.30) or X-linked adrenoleukodystrophy (E71.310). Documentation should clearly indicate a confirmed diagnosis of a peroxisomal disorder and specify that it is not one of the more commonly coded types.

• Always seek a more specific code within the E71.5 category if the documentation allows.
• Ensure the medical record explicitly states "other peroxisomal disorder" or provides details that rule out more specific codes.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis when it contributes to the patient's overall condition.
