Answer in brief HCC risk adjustment exists because not all patients cost the same to treat. CMS defines risk adjustment as a way to calculate payment based on a patient’s health status, expected service use, and expected cost, and it defines a risk score as a number that reflects predicted cost relative to the average Medicare patient. In plain English: chronic and complex conditions matter financially because they can change how illness burden is represented in payment.
The CMS-HCC model predicts expenditures and adjusts payment using diagnosis data and demographic factors. CMS’s Medicare managed care guidance says the model predicts beneficiaries’ expenditures relative to the average beneficiary and uses diagnoses plus demographics to adjust payments.
CMS’s 2024 Report to Congress says the 2024 CMS-HCC model includes count variables that adjust total predicted cost as the number of conditions increases. That means missing valid chronic conditions can understate the patient’s documented complexity, not just clinically but financially.
