ACOs are designed to provide coordinated, high-quality care while controlling costs. As part of this model, providers are held accountable for the total cost of care delivered to a specific patient population.

When providers participate in an ACO, they agree to manage the health of their patients while also being responsible for the costs associated with that care. This creates a shared savings model where if the costs of care exceed the predetermined level, the providers may incur financial losses. Therefore, the financial challenge arises from the risk of underestimating the actual cost of care needed, which can lead to a potential financial shortfall for the providers within the ACO structure.

In contrast, the other options do not accurately reflect the dynamics of ACOs. For instance, ACOs do not provide unlimited reimbursement for services, nor do they require physicians to purchase their own insurance. Additionally, they do not simplify billing processes; in fact, the coordination and accountability aspects can complicate the billing landscape.
