O64 — Obstructed labor due to malposition and malpresentation of fetus

Non-billable headerICD-10-CM

O64 is a non-billable header ICD-10-CM code for obstructed labor due to malposition and malpresentation of fetus. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

One of the following 7th characters is to be assigned to each code under category O64. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from category O64 that has a 7th character of 1 through 9.

0: not applicable or unspecified
1: fetus 1
2: fetus 2
3: fetus 3
4: fetus 4
5: fetus 5
9: other fetus

Other codes that can never be billed with O64

These codes carry an Excludes1 note pointing at O64. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O64 alone.

Risk adjustment

O64 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.

8 child codes. Green means billable.
