2024 Advance Notice Deep Dive Signals ‘Radical’ Change on the Horizon

Two weeks ago, CMS in its 2024 Advance Notice projected that Medicare Advantage organizations can expect an average estimated change in revenue of 1.03%, when accounting for underlying factors. Although the industry had been bracing for a much smaller rate increase than the robust 8% CMS predicted this time last year, a deeper dive into the notice has plan sponsors and providers understandably concerned about potential rate reductions. That’s largely because the annual rate notice, which often includes proposed changes to the risk adjustment model used to determine plan payments, proposes a substantial redesign of the model.

“This is the most radical change to the risk adjustment model since it started,” asserts risk adjustment consultant Richard Lieberman, who estimates that the Part C CMS-Hierarchical Condition Categories (HCC) model has gone through “four major iterations” since it was first used to adjust plan payments in 2004. One significant change in the proposed 2024 CMS-HCC model is that it has 115 payment HCCs, up from 86 in the current model, which was updated in 2020. In addition, CMS proposed moving from using ICD-9 diagnoses codes to the “more commonly used” ICD-10, as well as shifting to more recent underlying fee-for-service (FFS) Medicare data years to reflect 2018 diagnoses and 2019 expenditures (from 2014 diagnoses and 2015 expenditures).
