Hospital Medicine Has a Specialty Code. Is the Memo Still in the Mail?

The Centers for Medicare and Medicaid Services awarded Hospital Medicine a Medicare specialty code, "C6", in 2016. We examined the early uptake of C6 code using the 2017 Medicare Part B utilization data. We also compared the actual C6 specialty code usage against estimated rates of overall hospitalist billing using threshold-based hospitalist rates of Evaluation and Management codes to assess the integration of the newly introduced code. Billing activity associated with the C6 code was approximately one-tenth of expected rates. (c) 2020 Society of Hospital Medicine
