Tamarac® Medical bills Medicaid and most Medicaid Managed Care Organizations (MCOs) directly and accepts the allowable amount.  We can submit billing claims to all insurance companies; claims are processed by insurance companies according to individual plan terms.  There is no charge to the submitter when reimbursement is made by public or private insurance payers.  Charges for self-pay/uninsured patients are billed to the submitting facility at an economical group rate on a monthly basis.
