N.M. Code R. § 8.302.4.10
Health care to eligible recipients is furnished by a variety of providers and provider groups. The reimbursement and billing for these services is administered by MAD. Upon approval of a New Mexico MAD provider participation agreement by MAD or its designee, licensed practitioners, facilities and other providers of services that meet applicable requirements are eligible to be reimbursed for furnishing covered services to eligible recipients. A provider must be enrolled before submitting a claim for payment to the MAD claims processing contractors. MAD makes available on the HSD/MAD website, on other program-specific websites, or in hard copy format, information necessary to participate in health care programs administered by HSD or its authorized agents, including program rules, billing instructions, utilization review instructions, and other pertinent materials. When enrolled, a provider receives instruction on how to access these documents. It is the provider's responsibility to access these instructions, to understand the information provided and to comply with the requirements. The provider must contact HSD or its authorized agents to obtain answers to questions related to the material or not covered by the material. To be eligible for reimbursement, a provider must adhere to the provisions of the MAD provider participation agreement and all applicable statutes, regulations, and executive orders. MAD or its selected claims processing contractor issues payments to a provider using electronic funds transfer (EFT) only. The providers listed in Subsections A-C of 8.302.4.10 NMAC, eligible providers, are eligible for a provider participation agreement, bill and receive reimbursement for furnishing medical services:
