O47.0False labor before 37 completed weeks of gestation

O47.0 is the ICD-10-CM diagnosis code for false labor before 37 completed weeks of gestation. It belongs to category O47 (false labor), block O30-O48 (maternal care related to the fetus and amniotic cavity and possible delivery problems) 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 O47 (false labor), O47.0 is specifically for false labor before 37 completed weeks of gestation. Related codes cover at or after 37 completed weeks of gestation (O47.1) and unspecified (O47.9).

To report this condition, pick the subcode that matches the documentation: O47.00 (unspecified trimester), O47.02 (second trimester) and O47.03 (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.
