What This Code Means
O47.00 is the ICD-10-CM diagnosis code for false labor before 37 completed weeks of gestation, unspecified trimester. Contractions and labor-like symptoms that are not true labor occurring before 37 weeks of pregnancy, with unspecified timing. O47.00 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).
O47.00 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.
False labor (Braxton-Hicks contractions) must be documented as not progressing to active labor.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O47.00 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •False labor (Braxton-Hicks contractions) must be documented as not progressing to active labor
