In the past Aetna has dealt with this either by asking the doctors to resign or by withdrawing the capitated contract. In short, the doctors who have refused to resign have usually won. Physicians are trained to provide needed care for their patients, not to cut it back in order to avoid personal liability for the cost. Capitation shifts all the financial risk away from the insurers, whose business is to handle it, and lays it on the doctors who are not equipped to deal with it. By training, doctors are care givers, not risk-takers.
Capitation degrades their time honored professional role.
The League is currently challenging Aetna's capitation contracts in court on behalf of its members on exactly these grounds. The more members who support this case, the stronger our hand will be.
