Questions About O47Overview

What is the ICD-10 code for false labor?

O47 is the ICD-10-CM category for false labor, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is O47 (False labor) a billable code?

No. This is a category header that groups the codes for false labor, and headers cannot be submitted on claims. Claims for false labor need a more specific code from this category, such as O47.00, O47.02, and O47.03.

Can O47 be reported with a code from O60?

Not as a rule. The Excludes1 note on O47 lists "preterm labor (O60.-)". 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).
