Field notes
Search can start with a biller’s name, a hospital, or an NPI; a sample result connects an anesthesia group to named hospitals and shows its NPI and exclusions-list status.

It separates federal surprise-billing protections from ground-ambulance rules and notes that some states have their own provisions.
