Improving RVU Compensation Models to be More Equitable for Transplant Nephrologists
Key Takeaways
- Current compensation models are based on relative value units (RVUs), which do not account for nonmeasurable work. Only about 40% to 50% of the work done by transplant nephrologists is considered billable.
- There are 3 main issues with the RVU-based models: 1) They determine compensation by productivity benchmarks and do not factor in nonbillable activities. 2) Compensation is calculated to meet inaccurate fair market value (FMV) criteria. 3) Pay for transplant nephrologists is not standardized across different institutions.
- Some ways to improve current compensation models include integrating customized RVUs that account for nonbillable activities, utilizing outcome value metrics (OUV) instead of incentivizing performance, and incorporating Medicare Organ Acquisition Cost (OAC) reports to measure the full scope of physician work.
Workload and Salary of Transplant Nephrologists
The process of kidney transplantation has grown increasingly complex over the years, yet current compensation models for transplant nephrologists have failed to accurately reflect the full scope of their work, especially in regard to nonbillable activities.
For every kidney transplant performed, a transplant nephrologist provides 8 referrals and 4 evaluations. In 2023, 26 612 kidney transplants were performed in the US, which would have required approximately 213 000 referrals and 106 000 evaluations. This averages out to 365 to 456 patients per transplant nephrologist annually.
A shortage of transplant nephrologists results from inadequate compensation for this high volume of patients and heavy workload. Current data shows that US transplant nephrologists’ salaries rank lower than any other subspeciality. Surveys among professionals also show dissatisfaction with compensation models based on RVUs.
The Problems with RVU Compensation Models
RVU models focus on physician time, skill, and effort and calculate compensation by measurable outputs of productivity. However, transplant nephrologists spend only about 40% to 50% on billable activities. The other 50% to 60% include nonbillable activities such as chart review, waitlist management, clinic outreach, teaching, mentoring, and research. RVU-based models overlook all this essential labor, leading to gaps in proper compensation.
Another issue with RVU compensation models stems from the physician self-referral law (Stark Law), which forbids physicians from referring patients with Medicare to other health entities they have a financial relationship with. This law also requires hospitals and other health organizations to ensure physician compensation meets FMV criteria. However, FMV benchmarks are unreliable, magnifying inaccurate pay structures.
Finally, the differing settings that employ transplant nephrologists (hospitals, institutes, private medical practices, etc.) create discrepancies in pay for physicians across these various organizations. The lack of a direct link between transplant nephrologist activity and revenue generation makes compensation for individual contributions a challenge.
Possible Solutions
This paper calls for an improvement of the current RVU compensation system that involves customizing RVUs to account for nonbillable activities.
The authors also suggest using outcome value units (OVU) over performance-based incentives. “This approach ensures that compensation aligns with the true value of a transplant nephrologist’s contributions and advances the shift toward value-based medicine,” the authors said.
Another possible solution is to integrate Medicare OAC reports with current compensation models, which reflect the work transplant nephrologists do in pretransplant workup and administrative tasks.
The Benefits of Reform
Reforming current RVU compensation models to fully encompass the efforts of transplant nephrologists will help create a more equitable system. Additionally, these improvements could contribute to a more resilient workforce, enhancing physician well-being and decreasing rates of burnout.
