cystinosis (E72.04)
cystinuria (E72.01)
transcobalamin II deficiency (D51.2)

Other codes that can never be billed with E72.1

E72.1 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 E72.1
