Market Forces Factor

Each provider has a Market Forces Factor (MFF) (for example 1.123456) that is applied to national PbR tariff charges it raises to allow for local costs that differ from the reference costs used to generate the national tariff.

The tariff charged raised by each patient visit is factored by the providers’ MFF in place in the month that care was delivered. A commissioner will therefore pay a different amount for the same care delivered by different providers. This process is automatically implemented in the Integrated Sexual Health Grouper and therefore all the charges delivered by the Grouper include the appropriate MFF.
