Summary & Overview
Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh with MCC: Inpatient Reimbursement Overview
DRG 562 addresses fractures, sprains, strains, and dislocations except for the femur, hip, pelvis, and thigh when a Major Complication or Comorbidity is present; it defines the clinical scope for higher-acuity nonhip lower- and upper-extremity orthopedic and related injuries. Proper Diagnosis-Related Group assignment matters because the presence of a Major Complication or Comorbidity increases inpatient reimbursement under Medicare, reflecting greater resource use and care complexity.
DRG 562 Overview
DRG 562 covers inpatient cases involving fractures, sprains, strains, and dislocations of sites other than the femur, hip, pelvis, and thigh when a Major Complication or Comorbidity is present. This Diagnosis-Related Group captures higher-resource encounters driven by significant comorbid conditions or complications that increase length of stay and intensity of care. It matters for Medicare payment because the presence of a Major Complication or Comorbidity elevates the payment relative to similar injuries without such qualifiers. Hospitals and coders must accurately document the primary injury and any Major Complication or Comorbidity to ensure appropriate Diagnosis-Related Group assignment and reimbursement.
Clinical Trials
- Acute surgical and perioperative intervention trials: studies comparing different operative approaches, timing of surgery, or perioperative protocols for non-femur/hip/pelvis/thigh fractures and dislocations (for example, distal radius, ankle, elbow, shoulder) investigate outcomes such as complication rates, need for revision, blood loss, and length of stay. These trials enroll adult inpatients who present emergently with fractures, severe sprains, or joint dislocations requiring closed or open reduction and often fixation; they may stratify by injury severity and comorbidity burden (including patients with Medicare-age or multimorbidity). Results inform clinicians about safest and most effective acute management strategies and help payers anticipate resource use and justify coverage for specific surgical techniques or perioperative pathways.
- Comparative effectiveness and rehabilitation timing studies: randomized or pragmatic studies comparing immobilization versus early mobilization, different physical therapy regimens, or conservative care versus operative management for sprains, strains, and selected stable fractures. These studies typically recruit patients transitioning from acute inpatient management to early outpatient rehab or short inpatient recovery units, focusing on functional recovery, readmission rates, and return-to-work or activity metrics across age groups and activity levels. Findings guide providers on optimizing post-acute care plans to improve functional outcomes while helping payers identify which rehabilitation strategies reduce downstream costs such as prolonged therapy, repeat imaging, or readmissions.
- Post-discharge outcomes, utilization, and bundle-of-care studies: observational cohorts and health-services research evaluating 30- to 90-day outcomes (complications, ED revisits, readmissions), total cost of care, and the impact of discharge disposition (home with services vs skilled nursing facility) for patients with non-hip/pelvis fractures and dislocations with major comorbidities. These studies enroll the real-world inpatient population captured by this DRG — often older adults or patients with MCC — to identify predictors of high resource use and adverse outcomes and to test care-coordination or transitional-care interventions. Results are highly relevant to hospitals and payers designing payment bundles, care pathways, and discharge planning policies to reduce readmissions and overall episode costs while maintaining quality.
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.
