payer_id resolves on roughly two thirds of rows. The rest are directory payers the practice holds a mailing address for but has never saved as a payer of its own. claimmd_payer_id is populated on every row, so use it rather than payer_id when you need payer identity across the whole table.
This table’s columns and relationships are shown in the Hosted Database schema.
claimmd_payer_id is the Claim.MD payer directory code and is held as text. Not every value is numeric - PAPER, EAP20, and 00060 are all valid codes - so leading zeros are significant and it should not be cast to a number.zip formatting is inconsistent in the source. Both five-digit and nine-digit forms appear, with and without a hyphen, so normalize it before matching on it.- Where paper claims are mailed for a given payer
- Payers a practice holds an address for but has not saved
- Practices holding several addresses for the same payer
- Checking address completeness before a paper claim run
- Mailing addresses by state, to spot regional payer coverage
