Summary & Overview
Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC: Inpatient Reimbursement Overview
DRG 496 covers local excision and removal of internal fixation devices except hip and femur with a Complication or Comorbidity. It defines the clinical cases that receive adjusted inpatient reimbursement under Medicare due to the additional complexity associated with complications or comorbid conditions.
DRG 496 Overview
DRG 496 covers inpatient encounters for local excision procedures and removal of internal fixation devices, excluding hip and femur, when a Complication or Comorbidity is present. Typical cases include removal of plates, screws, rods, or hardware from upper and lower extremity sites other than the hip and femur, often with management of wound issues, infection, or other complications. This Diagnosis-Related Group matters for Medicare payment because the presence of a Complication or Comorbidity adjusts relative resource weights and influences reimbursement for hospitals. Accurate coding of the principal procedure and accompanying Complication or Comorbidity is essential for correct inpatient payment assignment.
Clinical Trials
- Acute perioperative infection prevention and management studies: randomized or observational studies evaluating protocols to prevent or treat surgical site and hardware-related infections in patients undergoing local excision or removal of internal fixation devices (excluding hip and femur). These trials focus on patients with recent fracture fixation hardware presenting for device removal or debridement, comparing antibiotic prophylaxis regimens, intraoperative antiseptic strategies, or early diagnostic algorithms for suspected hardware infection. Results are relevant to providers for optimizing perioperative care pathways and to payers because reducing infection-related readmissions, extended stay, and reoperation can substantially alter resource use and costs for this DRG.
- Comparative effectiveness studies of surgical approaches and anesthesia techniques: prospective cohort or randomized studies comparing different operative approaches (open vs minimally invasive hardware removal, regional vs general anesthesia, or use of intraoperative imaging guidance) in adults undergoing local excision and removal of fixation devices in upper or lower extremities (non-hip/femur). These studies assess outcomes such as procedure duration, intraoperative blood loss, complication rates including neurovascular injury, length of stay, and short-term functional recovery. Findings inform surgeons and hospital administrators on selecting techniques that balance clinical outcomes and hospital resource utilization, which impacts DRG-based reimbursement and case-mix considerations.
- Post-discharge functional recovery and utilization/outcomes research: prospective observational registries and health services research tracking patients after device removal for wound healing, pain control, return-to-function metrics, opioid use trajectories, and downstream healthcare utilization (e.g., outpatient visits, home health, readmissions). The population includes medically complex adults and elderly patients who may have comorbidities (diabetes, peripheral vascular disease) that affect healing and rehabilitation. This research is relevant to payers and care managers because understanding predictors of prolonged recovery or costly post-acute services supports discharge planning, targeted interventions to reduce avoidable utilization, and more accurate bundled-payment modeling for 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.
