Call ahead
Office hours change around open enrollment, and many agencies book appointments during the busiest weeks. Calling ahead saves a wasted trip.
How to get ready
- Check that the agent's license is active with the state regulator.
- Make a list of your doctors, hospitals and prescriptions before you call anyone.
- Have a realistic estimate of next year's household income; subsidies are based on it.
- Write down the enrollment deadline and confirm your first premium payment.
Checking an agent's license in Missouri
