How CMS will determine the price of automated testing profiles (ATPs) under the private payor rate-based CLFS payment system

For CY 2018, payment for tests that were bundled into ATPs will instead be made at the individual HCPCS code level. In other words, CMS will pay for each appropriately billed HCPCS code based on the CLFS amount for the specific code billed by the laboratory. Moving forward CMS will continue to consider the efficiencies of ATPs and the appropriate payment methods for these tests under the new private payor rate-based CLFS. Medicare administrative contractors will continue to apply editing to ensure that if a laboratory panel HCPCS code is submitted and is payable, an individual laboratory HCPCS code that is part of the same panel is not also paid separately.
