Non-billable headerICD-10-CM

O60 is a non-billable header ICD-10-CM code for preterm labor. 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.

Includes

Conditions this code covers.

  • onset (spontaneous) of labor before 37 completed weeks of gestation

Other codes that can never be billed with O60

These codes carry an Excludes1 note pointing at O60. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O60 alone.

Risk adjustment

O60 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 O60

3 child codes. Green means billable.
