States have the flexibility to account for the Health Insurance Providers Fee on a prospective or retroactive basis. In the event that a prospective calculation results in a capitation rate that is too high or too low, the capitation rate may be adjusted after the actual tax assessment is known. States may also account for the fee prospectively by withholding such amounts until the health plan's actual fee is known. The capitation payment, net the amount of the withhold, must remain actuarially sound and the state can only claim Federal Financial Participation (FFP) on the actual expenditures paid from the withhold to reimburse the health plans for the fee.
States may account for the Health Insurance Providers Fee as an aggregated retroactive adjustment to the rates for the contract year once a health plan's liability is known. CMS anticipates that states would move to a prospective calculation as states and health plans obtain more experience with the fee.
