Summary & Overview
Local Excision and Removal of Internal Fixation Devices of Hip and Femur without CC/MCC: Inpatient Reimbursement Overview
DRG 499 addresses inpatient admissions for local excision and removal of internal fixation devices of the hip and femur without a Complication or Comorbidity or Major Complication or Comorbidity, covering hardware removals such as plates, screws, and rods. This grouping matters for inpatient reimbursement because it places these procedures into a lower-severity Diagnosis-Related Group that affects payment rates and hospital resource allocation under Medicare.
DRG 499 Overview
DRG 499 covers inpatient stays for local excision and removal of internal fixation devices of the hip and femur without a Complication or Comorbidity or Major Complication or Comorbidity. It includes procedures to remove plates, screws, rods, or other fixation hardware when no significant comorbid conditions are coded. This Diagnosis-Related Group matters for Medicare payment because it groups relatively straightforward surgical hardware removals into a lower-severity payment category that influences reimbursement levels and resource expectations for hospitals.
Clinical Trials
- Studies of perioperative infection prevention and wound healing protocols for patients undergoing local excision or removal of hip and femur internal fixation hardware: randomized or pragmatic trials compare antibiotic prophylaxis regimens, topical antiseptics, or irrigation techniques in adults with prior traumatic fixation from fractures. These studies focus on patients presenting for hardware removal often months to years after initial fracture fixation, many with comorbidities such as diabetes or peripheral vascular disease that increase infection risk. Results are directly relevant to surgeons, hospital infection control teams, and payers because reducing surgical site infections shortens length of stay, lowers readmission rates, and decreases overall episode-of-care costs.
- Comparative effectiveness research evaluating approaches to hardware removal versus retention and targeted local excision strategies in symptomatic patients: observational cohort studies or randomized trials assess outcomes such as pain relief, functional recovery, reoperation rates, and perioperative complications in older adults or younger active patients with persistent pain, prominent hardware, or nonunion. This research addresses the clinical decision of whether to remove internal fixation devices and how extensive soft-tissue or bony excision should be, informing selection of patients who will derive net benefit from the procedure. Findings guide clinicians and payers on appropriate use of surgical resources, expected recovery trajectories, and which patient subgroups incur higher downstream costs.
- Post-discharge outcomes and rehabilitation pathway trials for patients after local excision or hardware removal of hip/femur implants: prospective studies examine optimized pain management protocols, physical therapy initiation timing, and care coordination interventions to reduce readmissions and improve mobility in the first 90 days after surgery. The patient population includes older adults and those with baseline mobility limitations or polypharmacy who are at greater risk for functional decline after brief inpatient stays. Results inform discharge planning, resource allocation for outpatient rehab services, and value-based payment models by identifying interventions that improve recovery and lower post-acute care utilization.
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.
