E71.51Disorders of peroxisome biogenesis

E71.51 is a non-billable header ICD-10-CM code for disorders of peroxisome biogenesis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Group 1 peroxisomal disorders

Other codes that can never be billed with E71.51

These codes carry an Excludes1 note pointing at E71.51. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E71.51 alone.

  • Q87.8Other specified congenital malformation syndromes, not elsewhere classified
  • E72.3Disorders of lysine and hydroxylysine metabolism

Risk adjustment

E71.51 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead E71.51

3 child codes. Green means billable.
