Final answer:
States have three main options regarding CHIP's structure: a separate CHIP program, a CHIP expansion of Medicaid, or a combination of both approaches.
Step-by-step explanation:
When considering the Children's Health Insurance Program (CHIP), states have three main structure options regarding its implementation. These options are:
Creating a CHIP program that is completely separate from the state's Medicaid program.
Implementing CHIP as an expansion of the state's existing Medicaid program.
Adopting a combination approach where the state runs CHIP in conjunction with the Medicaid program by using the same eligibility requirements and service delivery systems to some extent.
These structure options give states flexibility in designing their CHIP programs to best serve their populations' specific needs while adhering to federal guidelines.
