E71.5Peroxisomal disorders

E71.5 is the ICD-10-CM diagnosis code for peroxisomal disorders. It belongs to category E71 (disorders of branched-chain amino-acid metabolism and fatty-acid metabolism), block E70-E88 (metabolic disorders) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within E71 (disorders of branched-chain amino-acid metabolism and fatty-acid metabolism), E71.5 is specifically for peroxisomal disorders. Related codes cover Maple-syrup-urine disease (E71.0), other disorders of branched-chain amino-acid metabolism (E71.1), disorder of branched-chain amino-acid metabolism, unspecified (E71.2), disorders of fatty-acid metabolism (E71.3) and disorders of carnitine metabolism (E71.4).

To report this condition, pick the subcode that matches the documentation: E71.50 (unspecified), E71.51 (biogenesis), E71.52 (adrenoleukodystrophy), E71.53 (disorders) and E71.54 (disorders).

Don't report E71.5 together with the conditions in its Excludes1 note: Schilder's disease (G37.0).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
