Summary & Overview
Other Antepartum Diagnoses with O.R. Procedures without CC/MCC: Inpatient Reimbursement Overview
DRG 819 encompasses other antepartum diagnoses requiring operating room procedures in the absence of a Major Complication or Comorbidity or a Complication or Comorbidity. It defines the clinical scope for grouping resource use and directly impacts inpatient reimbursement under Medicare payment policies.
DRG 819 Overview
DRG 819 covers antepartum admissions for other maternal diagnoses that involve operating room procedures without a Major Complication or Comorbidity or a Complication or Comorbidity. Typical cases include surgical interventions during pregnancy that are not associated with higher-severity comorbid conditions. This Diagnosis-Related Group affects Medicare payment by grouping resource use and setting the inpatient prospective payment relative to other antepartum groups. Proper assignment influences inpatient reimbursement and hospital case mix reporting.
Clinical Trials
- Trials evaluating perioperative management strategies for antepartum patients undergoing obstetric or related non-obstetric OR procedures, focusing on optimizing timing of surgery, anesthesia approaches, and fetal monitoring protocols. These studies enroll pregnant women in their second or third trimester who require operative interventions for maternal conditions (e.g., cerclage, appendectomy, adnexal surgery) and compare immediate versus delayed interventions or different anesthetic techniques to balance maternal safety and fetal risk. Results inform clinical pathways that can reduce complications, length of stay, and unplanned neonatal or maternal intensive care needs—important for providers optimizing care and for payers interested in cost-effective inpatient management.
- Comparative effectiveness trials of diagnostic and surgical decision algorithms for antepartum complications that do not meet CC/MCC criteria, such as evaluation of imaging-guided versus clinical observation pathways for suspected adnexal masses or non-severe placental issues. These studies focus on pregnant patients with intermediate-risk presentations to determine which diagnostic-workup or minimally invasive operative choices best prevent escalation to severe morbidity while minimizing unnecessary OR utilization. Findings guide admission criteria, resource allocation, and procedural utilization decisions that affect reimbursement and DRG assignment consistency for hospitals and payers.
- Prospective cohort or outcomes research examining short-term maternal and neonatal outcomes and readmission rates after OR procedures without CC/MCC in the antepartum period, including patient-reported outcomes and health service utilization up to the postpartum period. These studies follow women discharged after index hospitalization to quantify rates of complications, subsequent obstetric interventions, and neonatal care needs, stratified by procedure type and gestational age at surgery. Evidence from these studies helps providers refine discharge planning and surveillance, and helps payers model post-discharge costs and quality metrics linked to this DRG.
Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.
