CAM Calculation Scenarios
CAM reconciliation math is straightforward in concept but error-prone in practice. Each calculation type (gross-up, pro-rata, caps, base year, true-up) has its own formula, edge cases, and common mistakes. These worked examples walk through each one with exact formulas, variable definitions, and realistic scenarios.
