2020 MIPS Measure #335: Maternity Care: Elective Delivery or Early Induction Without Medical Indication at < 39 Weeks (Overuse)

Quality ID 335
High Priority Measure Yes
Specifications Registry
Measure Type Outcome
Specialty Obstetrics/Gynecology

Measure Description

Percentage of patients, regardless of age, who gave birth during a 12-month period who delivered a live singleton at < 39 weeks of gestation completed who had elective deliveries or early inductions without medical indication.



This measure is to be submitted each time a procedure is performed for patients undergoing delivery or induction at less than 39 weeks gestation during the performance period. This measure may be submitted by Merit-based Incentive Payment System (MIPS) eligible clinicians who perform the quality actions described in the measure based on the services provided and the measure-specific denominator coding.

Measure Submission Type:

Measure data may be submitted by individual MIPS eligible clinicians, groups, or third-party intermediaries. The listed denominator criteria are used to identify the intended patient population. The numerator options included in this specification are used to submit the quality actions as allowed by the measure. The quality-data codes listed do not need to be submitted by MIPS eligible clinicians, groups, or third-party intermediaries that utilize this modality for submissions; however, these codes may be submitted for those third-party intermediaries that utilize Medicare Part B claims data. For more information regarding Application Programming Interface (API), please refer to the Quality Payment Program (QPP) website.



All patients, regardless of age, who gave birth during a 12-month period delivering a live singleton at < 39 weeks of gestation completed without medical indication for induction

Denominator Criteria (Eligible Cases):

All patients, regardless of age


Live Singleton (ICD-10-CM): Z37.0


Patient procedure during performance period (CPT): 59400, 59409, 59410, 59510, 59514, 59515, 59610, 59612, 59614, 59618, 59620, 59622


Delivery at < 39 weeks gestation



Patients who had elective deliveries or early inductions

Numerator Options:

Performance Met: Early elective delivery or early elective induction not performed (≥ 37 and < 39 weeks gestation) (G9355)


Denominator Exception: Medical indication for induction [Documentation of reason(s) for elective delivery (C-section) or early induction (e.g., hemorrhage and placental complications, hypertension, preeclampsia and eclampsia, rupture of membranes- premature or prolonged, maternal conditions complicating pregnancy/delivery, fetal conditions complicating pregnancy/delivery, late pregnancy, prior uterine surgery, or participation in clinical trial)] (G9361)


Performance Not Met: Early elective delivery or early elective induction performed (≥ 37 and < 39 weeks gestation) (G9356)



Elective delivery or early induction often leads to prematurity, increased costs, and an increased incidence of cesarean section. Studies have determined that elective delivery or elective cesarean section prior to the gestational age of 39 weeks may result in significant short-term neonatal morbidity (neonatal intensive care unit admission rates of 13%– 21%). Among women undergoing induction, women with their first pregnancies have a higher rate of cesarean delivery than women with prior vaginal births. Recent research shows that infants born prior to 39 weeks face a higher risk of breathing disorders and other problems than those who remain in the womb longer.


Clinical Recommendation Statements

The following evidence statements are quoted from the referenced clinical practice bulletin: American College of Obstetrics and Gynecologists Induction of Labor (ACOG 2009) and the ACOG Medically Indicated Late-Preterm and Early-Term Deliveries Committee Opinion, 2019.

Decisions regarding maternal delivery are complex and must take into account maternal and newborn risks, practice environment, and patient preferences. The goal of induction of labor is to achieve vaginal delivery by stimulating uterine contractions before the spontaneous onset of labor. Generally, induction of labor has merit as a therapeutic option when the benefits of expeditious delivery outweigh the risks of continuing the pregnancy. Labor may also be induced for logistic reasons, e.g., rapid labor, distance, or psychosocial reasons.

However, indications for induction of labor are not absolute but should take into account maternal and fetal conditions, gestational age, cervical status, and other factors. ACOG and the Society for Maternal-Fetal Medicine have long discouraged nonindicated delivery before 39 weeks of gestation because the neonatal risks of late pre-term (34 0/7–36 6/7 weeks of gestation) and early term (37 0/7–38 6/7 weeks of gestation) births are well-established, and the potential neonatal complications associated with elective delivery at less than 39 0/7 weeks are well described. Based on these and other data, timing of elective delivery at 39 weeks of gestation or later is recommended. However, deferring delivery to 39 weeks of gestation is not recommended if there is a medical or obstetric indication for early delivery.

In some cases, health providers will need to weigh competing risks and benefits for the woman and her fetus. The following are examples of maternal or fetal conditions that maybe indications for induction of labor early or late term:

  • Placenta previa
  • Suspected accrete, increate, or percreta
  • Vasa previa
  • Prior classical cesarean
  • Prior myomectomy requiring cesarean delivery
  • Previous uterine rupture
  • Oligohydramnios
  • Polyhydramnios
  • Growth restriction
  • Multiple gestations—uncomplicated
  • Multiple gestations—complicated
  • Alloimmunization
  • Hypertensive disorders of pregnancy
  • Diabetes
  • HIV
  • Intrahepatic cholestasis of pregnancy
  • PROM (prelabor rupture of membranes)
