Practitioner.qualification for payer certifications?

As a payer, UnitedHealthcare has a Premium designation program which identifies network providers who have met certain objective cost and quality measures. And so when we expose our network provider list as Practitioner resources we want to allow for searching based on Premium status. The description for Practitioner.qualification seems ambiguous about that use case.
