DELAY!!! IMPORTANT UPDATE: The next data reporting period is January 1, 2024 through March 31, 2024, will be based on the original data collection period of January 1, 2019 through June 30, 2019.

• On December 29, 2022, Section 4114 of Consolidated Appropriations Act, 2023 revised the next data reporting period for CDLTs that are not ADLTs and the phase-in of payment reductions under the Medicare private payor rate-based CLFS. The next data reporting period of January 1, 2024 through March 31, 2024, will be based on the original data collection period of January 1, 2019 through June 30, 2019. After the next data reporting period, there is a three-year data reporting cycle for CDLTs that are not ADLTs (that is 2027, 2030, etc.).
• Section 1834A of the Act, as established by Section 216(a) of the Protecting Access to Medicare Act of 2014 (PAMA), required significant changes to how Medicare pays for Clinical Diagnostic Laboratory Tests (CDLTs) under the CLFS. The CLFS final rule “Medicare Clinical Diagnostic Laboratory Tests Payment System Final Rule” (CMS-1621-F) was published in the Federal Register on June 23, 2016. The CLFS final rule implemented section 1834A of the Act. Under the CLFS final rule, reporting entities must report to CMS certain private payer rate information (applicable information) for their component applicable laboratories. The data collection period (the period where applicable information for an applicable laboratory is obtained from claims for which the laboratory received final payment during the period) was from January 1, 2019 through June 30, 2019.
• The statutory phase-in of payment reductions resulting from private payor rate implementation is extended, that is, through CY 2026. There is a 0.0 percent reduction for CYs 2021, 2022, and 2023 and payment may not be reduced by more than 15 percent for CYs 2024 through 2026.

Do I need to submit private payor rates?

The Protecting Access to Medicare Act of 2014 (PAMA) required significant changes to how Medicare pays for clinical diagnostic laboratory tests under the Clinical Laboratory Fee Schedule (CLFS). Effective January 1, 2018, the payment amount for most tests equals the weighted median of private payor rates. Payment rates under the private payor rate-based CLFS are updated every three years. 

If you are a laboratory, including an independent laboratory, a physician office laboratory or hospital outreach laboratory that meets the definition of an applicable laboratory you are required to report information including laboratory test HCPCS codes, associated private payor rates, and volume data.
