Final answer:
The part that can be excluded from an individual accident and health policy is coverage for individuals with preexisting conditions.
Step-by-step explanation:
The provisions that may not be excluded from an individual accident and health policy are coverage for the uninsured, coverage for individuals with preexisting conditions, and the employer and individual mandates. These provisions are guaranteed by the Affordable Care Act (ACA), also known as Obamacare. However, with the new Trump administration, the ACA is under scrutiny and some components may face repeal or drastic changes.
Therefore, the part that can be excluded from an individual accident and health policy is coverage for individuals with preexisting conditions. This means insurance companies have the ability to exclude coverage for preexisting conditions in certain circumstances, although the ACA provides protections against this exclusion for most plans.
