N.M. Admin. Code § 8.320.6.16
Certain procedures or services identified in the UR instructions may require prior authorization from MAD or its designee. Services for which prior authorization was obtained remain subject to UR at any point in the payment process. All services are subject to UR for medical necessity and program compliance. Reviews can be performed before services are furnished, after services are furnished and before payment is made, or after payment is made. When services are billed to and paid by a coordinated services contractor authorized by HSD, the provider must follow that contractor's instructions for authorization of services. A specific service may have additional prior authorization requirements listed in the service's prior authorization section. The prior authorization of a service does not guarantee that an individual is eligible for a MAD service. A provider must verify that an individual is eligible for a specific MAD service at the time the service is furnished and must determine if the eligible recipient has other health insurance. A provider who disagrees with the denial of a prior authorization request or other review decision can request a reconsideration.
