Questions About O60Overview

What is the ICD-10 code for preterm labor?

O60 is the ICD-10-CM category for preterm labor, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is O60 (Preterm labor) a billable code?

No. This is a category header that groups the codes for preterm labor, and headers cannot be submitted on claims. Claims for preterm labor need a more specific code from this category, such as O60.00, O60.02, and O60.03.

Can O60 be reported with a code from O47.0?

Not as a rule. The Excludes1 note on O60 lists "false labor (O47.0-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
