Summary
Work relative value units (wRVUs) for limb lengthening surgery are significantly lower per hour than for ACL reconstruction or scoliosis surgery. Limb lengthening patients also require more postoperative visits, impacting surgeon reimbursement.
Area of Science:
- Orthopaedic surgery
- Health economics
- Surgical outcomes
Background:
- Reimbursement for surgical procedures is determined by relative value units (RVUs) based on work, resources, and expertise.
- The limb lengthening field has evolved, necessitating an evaluation of RVU comparability across orthopaedic subspecialties.
Purpose of the Study:
- To compare the work relative value unit (wRVU) totals for three common pediatric orthopaedic surgeries: arthroscopic ACL reconstruction, spinal fusion for adolescent idiopathic scoliosis, and antegrade femoral intramedullary limb lengthening.
- To assess if RVU values are comparable across different orthopaedic subspecialties.
Main Methods:
- A multicenter, retrospective chart review of 50 cases per procedure (ACL reconstruction, spinal fusion, femoral lengthening).
- Comparison of mean procedure duration, CPT codes billed, postoperative visits within the 90-day global period, and wRVU.
- Study design: Level III-retrospective comparison.
Main Results:
- The antegrade femur lengthening group had the lowest wRVU per hour (P < 0.0001).
- Limb lengthening patients had significantly more postoperative visits in the 90-day global period (P < 0.0001).
- Intramedullary limb lengthening procedures had the fewest CPT codes billed.
Conclusions:
- RVUs per time are lowest for limb lengthening and highest for scoliosis surgery.
- Limb lengthening patients require more postoperative visits and time, which do not add RVU value and occupy valuable clinic slots.
- A review of RVU values for limb lengthening codes is recommended.
