What This Code Means
O60.03 is the ICD-10-CM diagnosis code for preterm labor without delivery, third trimester. Labor that begins before 37 weeks during the third trimester (weeks 28 and beyond) of pregnancy without delivery occurring. O60.03 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering complications of labor and delivery (o60-o77).
O60.03 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.
Third trimester begins at week 28; confirm gestational age documentation to ensure accurate code selection.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O60.03 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
