This document provides an overview of risk adjustment and HCC coding. It discusses how accurate HCC coding is important for provider reimbursement, as CMS uses HCC codes to calculate risk scores and adjust Medicare Advantage plan payments. The document outlines the four steps in the process: 1) providers document clinical information, 2) CMS calculates risk scores, 3) CMS pays insurers based on risk scores, and 4) insurers pay providers based on accurate HCC coding. It also describes MiraMed's HCC coding services which identify missed codes to increase provider revenue through retrospective audits.
