Non-billable headerICD-10-CM

P51 is a non-billable header ICD-10-CM code for umbilical hemorrhage of newborn. 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.

omphalitis with mild hemorrhage (P38.1)
umbilical hemorrhage from cut end of co-twins cord (P50.5)

Other codes that can never be billed with P51

These codes carry an Excludes1 note pointing at P51. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P51 alone.

P38Omphalitis of newborn

Risk adjustment

P51 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 P51

3 child codes. Green means billable.
