New Mexico Service Delivery Resources and Policies

Rendering services and seeking reimbursement within Medicaid or other state funds has several requirements. Be sure to become familiar with each of them, including the policies of the Managed Care Organizations (MCOs) that your agency contracts with. Each MCO has their own provider manual that you will want to become familiar with. Some NMACs below may not apply to all providers or all services. If you have questions, be sure to contact our clinical team, your MCO, or the Medical Assistance Division (MAD).

Critical Incident Reporting
It is important to work with your contracted MCOs, Optum Health NM, and/or Xerox as appropriate on reporting critical incidents. Each New Mexico State Department may have its own reporting protocols. Anyone billing Medicaid, state, or other federal funds received through the state must report critical incidents. There is a HSD/BHSD state-issued BH CIR Protocol issued as of 2015 that all payors have been provided. That protocol is downloadable from the HSD Portal which is an online entry system that requires login. Please use the email address at the portal to request further information about using the portal. The CIR portal can be found here.

Technical Assistance
You may request Technical Assistance (TA) from either the MCOs or the State Department from which you are seeking reimbursement to help inform your practice and to understand how the rules above apply and/or should be operationalized. Email for information on TA for behavioral health-related service and program delivery or provider allowances.
