Choosing a provider
Checking whether a doctor is in network before you switch.
A doctor listed in a directory is not always in your plan's network today. Directories fall out of date, and a clinic can take your insurance while a specific doctor in it does not.
These pages walk through confirming network status with both the office and your insurer, asking the right questions before you book, and what to write down so you can point to it later if a bill surprises you.
