The Resource‐Based Relative Value Scale Update Committee () submits recommended reimbursement values for physician work (s) under Medicare Part B. The includes rotating representatives from medical specialties.
To identify changes in physician reimbursements associated with rotating seat representation.
Relative Value Scale Update Committee members 1994–2013; Medicare Part B Relative Value Scale 1994–2013; Physician/Supplier Procedure Summary Master File 2007; Part B National Summary Data File 2000–2011.
I match service and procedure codes to specialties using 2007 Medicare billing data. Subsequently, I model s as a function of rotating committee representation and level of code specialization.
An annual rotating seat membership is associated with a statistically significant 3–5 percent increase in Medicare expenditures for codes billed to that specialty. For codes that are performed by a small number of physicians, the association between reimbursement and rotating subspecialty representation is positive, 0.177 (SE = 0.024). For codes that are performed by a large number of physicians, the association is negative, −0.183 (SE = 0.026).
Rotating representation on the is correlated with overall reimbursement rates. The resulting differential changes may exacerbate existing reimbursement discrepancies between generalist and specialist practitioners.
