N.M. Admin. Code § 8.15.2.19
If a provider receives payment for services for which he/she is not entitled, or a client receives benefits on behalf of their child for which he/she is not entitled, and this results in an overpayment, the child care worker will initiate recoupment procedures unless the early childhood services director deems otherwise in exceptional circumstances. Recoupments will only be sought from providers. The department will not seek a recoupment from a client unless substantiated fraud by that client has been determined. The client or provider must repay the amount of the overpayment to the department within 30 calendar days of notification, unless the department determines that the amount is so large that it cannot be paid in one lump sum. In this case, the department may allow the client or provider to repay the amount over a payment period, negotiated between the client and the department, usually not to exceed four months. Failure to pay the overpayment within 30 days of the notice or failure to make regular payments under an agreed upon payment schedule may result in sanctions including termination of benefits or referral of the account to a collection agency or legal action.
