Would it be possible to get some elaboration or high level examples of what the "Vendor" field represents? I understand PCP and Provider ID, but I'm not clear on Vendor.
For example, for a visit to a Specialist, the PCP identifies the members Primary Care Provider (which is not, in general, claim specific) and the Provider ID identifies the Specialist that the member visited (I'm assuming). What would the Vendor represent?
Similarly, for an Inpatient Hospital stay, the Provider ID identifies the Hospital the member went to (I'm assuming). What does Vendor represent in this case?
