What This Code Means
O47.03 is the ICD-10-CM diagnosis code for false labor before 37 completed weeks of gestation, third trimester. Contractions and labor-like symptoms that are not true labor occurring during the third trimester (weeks 27-36) of pregnancy. O47.03 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering maternal care related to the fetus and amniotic cavity and possible delivery problems (o30-o48).
O47.03 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This is the most common time for false labor; ensure documentation confirms no cervical dilation or labor progression.
