    Other Multiple Significant Trauma without CC/MCC: Inpatient Reimbursement Overview

    DRG 965 applies to inpatient admissions for other multiple significant traumatic injuries without a Complication or Comorbidity or Major Complication or Comorbidity. It defines the clinical scope for grouping trauma resource use and matters for inpatient reimbursement because correct assignment determines Medicare payment levels and impacts hospital case-mix and revenue.

    DRG 965 Overview

    DRG 965 covers inpatient hospital admissions for patients with multiple significant traumatic injuries without a Complication or Comorbidity and without a Major Complication or Comorbidity. Typical cases include multisystem trauma where injuries are serious enough to require significant resources but do not meet the criteria for higher-severity payment adjustments. This Diagnosis-Related Group is important for Medicare payment because it groups resource use for complex trauma care and determines relative reimbursement compared with higher- or lower-severity trauma categories. Accurate assignment affects hospital payment and case-mix reporting under the Centers for Medicare & Medicaid Services inpatient prospective payment framework.

    Clinical Trials

    • Acute hemostatic and resuscitation intervention trials: randomized or pragmatic studies testing timing, mode, or protocols of hemorrhage control and fluid/blood product resuscitation in patients with multiple significant traumatic injuries presenting to the emergency department or operating room. These studies enroll severely injured adults or adolescents classified as multiple significant trauma without major comorbid complications, and evaluate short-term outcomes such as time-to-hemostasis, transfusion volume, need for emergent surgery, and in-hospital mortality. Results are directly relevant to hospital clinicians and payers because improvements in early intervention can reduce ICU use, transfusion costs, reoperations, and length of stay for this high-acuity DRG cohort.
    • Comparative effectiveness studies of surgical versus nonoperative management strategies: observational cohorts or randomized trials comparing approaches (for example, operative fixation versus nonoperative stabilization) for particular injury patterns within the multiple-trauma population, such as pelvic fractures, long-bone fractures with associated torso injuries, or complex chest trauma. These studies focus on mid-term outcomes including complication rates (infection, thromboembolism), functional recovery, reoperation, and resource utilization across diverse trauma patients without major CC/MCC, helping define which patients benefit from early definitive surgery versus staged or conservative care. Findings inform clinical pathways, discharge planning, and payment models by identifying strategies that optimize recovery while minimizing readmissions and total inpatient costs.
    • Post-discharge outcome and rehabilitation trials: prospective studies and program evaluations testing coordinated inpatient-to-outpatient rehabilitation, multidisciplinary discharge interventions, or home-based recovery programs for survivors of multiple significant trauma to measure functional status, return-to-work, readmission rates, and long-term healthcare use. These trials typically enroll patients who survived the index hospitalization without major comorbid complications but who are at risk for physical disability, chronic pain, or prolonged utilization. Evidence from these studies matters to providers and payers because effective post-discharge care can shorten future acute care utilization, reduce durable medical equipment and outpatient therapy costs, and improve patient-centered outcomes that influence overall value for this DRG population.
