Did you know the Payor ID or Electronic Data Interchange (EDI) is a unique ID assigned to each insurance company. It allows provider and payor systems to talk to one another to verify eligibility, benefits and submit claims. The payor ID is generally five (5) characters, but it may be longer. It may also be alpha, numeric or a combination. DDKS has two payor IDs available: E3960 and CDKS1 are both valid to use for electronic claim submissions.
