Membership medicine is not a replacement for fee-for-service primary care. It is a complementary model that can coexist within health systems and academic environments. 

We view membership medicine as: 

• A way to right-size panels for a defined patient population 

• A mechanism to fund time, continuity, and team-based care 

• An option that preserves insurance participation while adding modest patient contribution 

• A strategy that can improve physician retention and recruitment 

• A model that can be deployed selectively, not universally 

Most importantly, it can be introduced without destabilizing existing primary care operations.
