How to avoid rejects of Medicare and Medicaid crossover claims

Are your Medicaid crossover claims rejecting?

If you answered yes, it may be due to the address you have on file with Medicare and Medicaid. When Medicare crosses over your claim to Medicaid the following address fields are submitted:

• Master address

• Pay-to (or remit address) (if they are different on Medicare's system)

If Medicaid does not have the same addresses in their file, Medicaid will reject the claim.

Medicaid validates the crossover claims as follows:

1. National provider identifier (NPI)

2. NPI to taxonomy code (if applicable)

3. NPI to ZIP code

What you can do to avoid rejects

• Verify you have the exact same addresses on file with both Medicare and Medicaid

• Make sure your addresses are current and in the ZIP+4 external link

(i.e., nine-digit ZIP code) format

How to update your Medicare enrollment record

If you do not have the correct addresses on file with Medicare, please update your enrollment file by completing the appropriate CMS-855 form. To expedite the processing of your application, please use the internet-based Provider Enrollment, Chain, and Ownership System (PECOS) external link
