Medicare Advantage vs. Traditional Medicare
Medicare Advantage (MA) plans are administered by private insurance companies under contract with CMS. Unlike traditional Medicare, each MA plan can have different formularies, network restrictions, prior authorization requirements, and coverage rules โ making billing significantly more complex.
Prior Authorization Requirements in MA Plans
MA plans have far more prior authorization requirements than traditional Medicare. A 2022 HHS report found MA plans denied 6.7% of all prior authorization requests that would have been approved under traditional Medicare. Understanding each plan's specific requirements is critical.
HCC Coding and Risk Adjustment
Medicare Advantage uses Hierarchical Condition Categories (HCC) for risk adjustment โ meaning accurate and complete diagnosis coding directly affects your plan's capitation rate and your compliance risk. Ensure all chronic conditions are coded annually with appropriate specificity.
Common MA Billing Mistakes
- Not checking each MA plan's specific prior auth list (they differ from each other)
- Billing with traditional Medicare rules when MA rules apply
- Incomplete HCC coding that leaves risk adjustment revenue on the table
- Missing MA-specific timely filing deadlines (often shorter than standard Medicare)
Managing Multiple MA Plans
A practice may contract with 8โ15 different MA plans, each with different rules. A virtual billing specialist dedicated to MA can manage the complexity, track authorization requirements by plan, and ensure claims meet each plan's unique requirements.
