Excludes1 — never code together

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

abnormal glucose in pregnancy (O99.81-)
diabetes mellitus (E08-E13)
dysmetabolic syndrome X (E88.81-)
gestational diabetes (O24.4-)
glycosuria (R81)
hypoglycemia (E16.2)
type 1 diabetes mellitus, presymptomatic (E10.A-)

Risk adjustment

R73.0 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 R73.0

4 child codes. Green means billable.
