P56 — Hydrops fetalis due to hemolytic disease

Non-billable headerICD-10-CM

Excludes1 — never code together

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

hydrops fetalis NOS (P83.2)

Other codes that can never be billed with P56

These codes carry an Excludes1 note pointing at P56. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P56 alone.

Risk adjustment

P56 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 P56

2 child codes. Green means billable.
