O90.4 — Postpartum acute kidney failure
O90.4 is a non-billable header ICD-10-CM code for postpartum acute kidney failure. It cannot be billed on its own: choose one of the more specific child codes below.

- anuria and oliguria (R34)
Other codes that can never be billed with O90.4
These codes carry an Excludes1 note pointing at O90.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O90.4 alone.
Risk adjustment
O90.4 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 O90.4
