Clearinghouse Enrollment for Atypical Providers

Update: National Provider Identifier (NPI) is required when billing, unless enrolled as an atypical provider. Claims will no longer be rejected at Availity for a missing NPI once you have completed the enrollment process. The rejection for a missing NPI will be received by your chosen clearinghouse and it will be their responsibility to enroll. If either the provider or chosen clearinghouse has questions about the process of enrolling as an atypical provider, you can contact the Client Services team at 1-800-Availity.

MeridianComplete may add new clearinghouses from time to time, so please contact Provider Services at 1-855-323-4578 to see if your clearinghouse partner is on the list.

Submit Claims by Mail

You can also submit claims for payment through the mail:

ATTN: Claims Department
PO Box 3060
Farmington MO 63640

If you are re-submitting a claim for a status or a correction, please indicate “Status” or “Claims Correction” on the claim.
