One thing about capitation systems that can be very important to pay attention to is the scope. Of course the scope can vary a lot. One can find what we call partial capitation models, where the scope includes a subset of medical care. It may be natural, for example, for the scope of an agreement with a particular practice to include the kinds of services that that practice normally provides. Capitation for outpatient primary care is a good example, a common one. That would generally cover a standard set of primary care services under the capitation agreement. This would leave other things outside the scope of the capitation agreement. If the primary care provider refers the patient to a specialist, or if the patient is hospitalized, then the plan would have to have different payment arrangements in place to cover those. The scope of agreements can be much broader as well. At the broadest, we have something we call global capitation. Here, a provider organization would accept a single capitation payment for all of the medical care a patient might need in a time period, like a month. The organization accepting the capitation agreement would have a panel of patients assigned to it. And it would be responsible for all the medical care they need. Primary care, specialty care, hospitalizations, tests, and so on and so on. The extent of the scope is very broad. So I guess I do have to say here that even there there would be some limitations. For example, dental care or vision care would often not be included. The capitation rate then, the PMPM amount would depend on the scope. The PMPM for a broad arrangement like global cap, global capitation, would be much higher than the amount for narrower, say primary care only capitation. And of course that makes sense because the responsibility is much broader. Moving from narrower partial capitation arrangements to broader, more global capitation arrangements entails a major change in responsibility and risk. Broad arrangements, global capitation is not for the faint of heart. It's a lot of responsibility to accept and it entails a lot of risks. If the assigned patients have a really bad month and need lots of expensive care, the provider organization is going to be on the hook for that and needs to be able to handle it. Some organizations can handle this. And they might even find benefit in doing it this way. It'll often be pretty large organizations with lots of providers and the capability to deliver a very broad range of care. So pay attention to scope when you're looking at capitation arrangements. It can really help sort out what's going on in them.
