Summary & Overview

Other Multiple Significant Trauma with CC: Inpatient Reimbursement Overview

DRG 964 encompasses patients with multiple significant traumatic injuries including at least one Complication or Comorbidity but no Major Complication or Comorbidity, representing a high-resource inpatient trauma population. Understanding this Diagnosis-Related Group is important because it determines Medicare inpatient reimbursement and influences hospital case-mix index and payment under the prospective payment framework.

DRG 964 Overview

DRG 964 covers hospital admissions for patients with multiple significant traumatic injuries where at least one injury is a Complication or Comorbidity and there is no Major Complication or Comorbidity present. This Diagnosis-Related Group aggregates complex trauma care that typically requires multisystem evaluation, operative or nonoperative interventions, and extended inpatient resource use. It matters for Medicare payment because it groups resource intensity for reimbursement and affects hospital case-mix and prospective payment calculations. Accurate clinical documentation and coding determine assignment to this Diagnosis-Related Group and related payment implications.

Clinical Trials

Acute hemostasis and resuscitation trials: randomized or pragmatic studies testing timing, ratios, and protocols for blood product transfusion, tranexamic acid administration windows, and damage-control resuscitation strategies in adult and adolescent patients with multiple significant traumatic injuries and at least one complicating comorbidity (eg, anticoagulation, advanced age). These trials focus on the hyperacute phase (prehospital and first 24 hours) to reduce mortality and control hemorrhage, and are relevant because early management drives ICU needs, procedure utilization, and short-term mortality that heavily influence inpatient resource use and DRG cost variability. Providers benefit from evidence to optimize protocols across trauma centers, while payers and hospital administrators need data on which acute approaches reduce expensive downstream interventions and length of stay.
Comparative effectiveness studies of operative versus nonoperative management across injury patterns and comorbid conditions: multicenter observational cohorts or randomized studies evaluating outcomes for specific combinations of injuries (eg, polytrauma with pelvic fracture plus thoracic injury) and common complicating conditions (eg, chronic heart disease, diabetes). These studies examine functional outcomes, complication rates, reoperation or readmission frequency, and resource utilization during the index hospitalization and up to 90 days, helping determine which management pathways produce better recovery with fewer complications in the multiple-significant-trauma population with a CC. Such evidence guides surgical decision-making and care pathways, directly impacting inpatient costs, DRG assignment complexity, and payer decisions about bundled payments or prior authorization for high-cost procedures.
Post-discharge recovery, complications surveillance, and rehabilitation effectiveness studies: prospective cohort studies and pragmatic trials testing timing/intensity of inpatient-to-outpatient rehabilitation, transitional care interventions, and surveillance strategies to detect late complications (eg, infection, thromboembolism, wound failure) in survivors of multiple significant trauma who had concurrent complicating conditions. These studies target the subacute period (discharge to 12 months), measure functional status, readmissions, and need for home health or long-term care, and are important because post-acute outcomes drive total cost of care, long-term disability rates, and readmission penalties that affect both providers and payers managing patients classified under this DRG.
