Does getting multiple bills for one visit mean I was billed twice?

Not automatically. One visit can generate separate bills from different entities, so the key question is whether each bill reflects a distinct service or provider role.

How can I tell whether two bills are duplicates or separate charges?

Compare the provider name, service description, date of service, and EOB details. Duplicate-looking bills may still be separate if different groups were involved in the same visit.

Why Did I Get Multiple Medical Bills for One Visit?

You can receive multiple medical bills for one visit because different entities may bill separately for the same overall encounter. A hospital facility, physician group, lab, imaging group, or other specialist may each send its own statement, which is why matching each bill to the right provider and EOB matters.
