Key result
The proposed RBRVS-based billing matrix strongly correlated with current ASA relative value guide methodology payments (r=0.94-0.96, P<0.001) and would nearly double Medicare reimbursement.
Observational (n=1,195)
Effect estimate: r=0.94-0.96
p-value: p=<0.001
A proposed RBRVS-based billing matrix for anesthesia services correlates strongly with current ASA methodology while better valuing care for complex patients.

May inform anesthesia reimbursement reform discussions; leaves open prospective validation before Medicare adoption.
Sinclair et al. (2014) conducted an observational in Anesthesia service (n=1,195). Proposed RBRVS-based billing matrix vs. Current ASA relative value guide methodology was evaluated on Correlation between proposed RBRVS billing matrix payments and current ASA relative value guide methodology payments (r=0.94-0.96, p=<0.001). The proposed RBRVS-based billing matrix strongly correlated with current ASA relative value guide methodology payments (r=0.94-0.96, P<0.001) and would nearly double Medicare reimbursement.
