Effective 1/1/07, pharmacies will be required to inform Medicaid when any third party payer, including Medicare, has paid on a claim including when billing for co-pay amounts. The other insurance payment should be indicated on the claim in the appropriate field.
For claims submitted electronically, use the "Other COB (Coordination of Benefit)" fields to specify carriers, insurance payments, any Adjustment Reason Codes (ARCs) plus any further information as applicable. For claims submitted on paper, make sure you fill in the "Other Insurance Amount" on the claim form and attach the other insurance EOB.
