An in-person meeting helps when your situation has moving parts: a household with mixed coverage, self-employment income that changes, or a doctor you need to keep.
Call ahead
Office hours change around open enrollment, and many agencies book appointments during the busiest weeks. Calling ahead saves a wasted trip.
What to bring
Photo ID, Social Security numbers for everyone applying, a recent pay stub or income estimate, and a list of your doctors and prescriptions.
Before you call an agent
- Make a list of your doctors, hospitals and prescriptions before you call anyone.
- Check that the agent's license is active with the state regulator.
- Have a realistic estimate of next year's household income; subsidies are based on it.
- Ask each agent which carriers they can quote in your county.
Checking an agent's license in Missouri
- The Missouri Department of Commerce & Insurance offers a License & Contact Info search where consumers can check an agent's or agency's license. It also shows the agency an agent represents. Source
