Medicare Advantage hierarchical condition categories: Updated study results
By Javier Sanabria
The pressure on Medicare Advantage (MA) plans to ensure that risk scores appropriately reflect the health status of their population under the Patient Protection and Affordable Care Act (PPACA) continues to increase. Payment rates from the fee-for-service (FFS) phase-in as well as changes in star ratings for MA plans have been impacted.
The Centers for Medicare & Medicaid Services (CMS) assigns a risk score to every MA member based on the member’s characteristics, including age, gender, disability status, Medicaid status, and “health” status. The majority of revenue received by MA plans is based on the risk scores of their members, and the health status is the primary variable in the calculation of the risk score.
CMS determines the diseases/hierarchical condition categories (HCCs) for each member based on ICD-9 diagnosis codes. Identifying and submitting all appropriate ICD-9 diagnosis codes to CMS results in a higher risk score for the member and an increased payment to the MA plan.
