New Mexico Medicaid Enrollment and Claims Denial

November 30, 2016

Blue Cross and Blue Shield of New Mexico (BCBSNM) has previously communicated the requirement for all providers (both billing and rendering) who are contracted with BCBSNM for Blue Cross Community Centennial to enroll in the New Mexico Medicaid program. The requirement assures that billing providers and rendering providers can always be identified on claims and encounter reports by having their NPI numbers registered in the Medicaid provider file, which is maintained by the New Mexico Human Services Department's (HSD's) fiscal agent (Xerox) through its Omnicaid system. This requirement also assures BCBSNM's encounter submission data will be accepted by the Medical Assistance Division (MAD).

Effective Jan. 1, 2017, all claims will be denied if a provider is not enrolled in the Medicaid program with an NPI that is associated with an active fee-for-service or managed care provider record in the Omnicaid system. Every NPI/Taxonomy combination must be registered before submitting claims.

If you have not previously enrolled, do so immediately. If you have previously enrolled, verify that the taxonomy code used during the enrollment process is correct.
