Final answer:
Both the Independent Practice Association (IPA) and Health Maintenance Organizations (HMOs) contract with physicians in the IPA model.
Step-by-step explanation:
In the IPA model, both the Independent Practice Association (IPA) and Health Maintenance Organizations (HMOs) contract with physicians. However, the specific arrangement can vary depending on the organization and the contract between the parties involved.
An IPA is an organization that contracts with individual physicians or physician groups who are in private practice. The IPA negotiates contracts with health insurance companies, employers, or government entities on behalf of the participating physicians. These contracts specify the reimbursement rates, services covered, and other terms and conditions.
HMOs, on the other hand, are managed care organizations that typically employ or contract with physicians and other healthcare providers directly. The physicians are usually paid a fixed amount per member per month, regardless of the services provided, as part of a capitated payment arrangement. HMOs often have their own network of healthcare providers and may require members to choose a primary care physician (PCP) who manages their overall healthcare.
