About O60.0

O60.0 is the ICD-10-CM diagnosis code for preterm labor without delivery. It belongs to category O60 (preterm labor), block O60-O77 (complications of labor and delivery) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within O60, choose O60.0 (without delivery) only when documentation doesn't support a more specific option: with preterm delivery (O60.1) and term delivery with preterm labor (O60.2).

To report this condition, pick the subcode that matches the documentation: O60.00 (unspecified trimester), O60.02 (second trimester) and O60.03 (third trimester).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
