Coordination of Benefits (COB)
CareSource has contracted with Health Management Systems (HMS) to identify CareSource members who have other insurance coverage and to make sure claims are paid by the appropriate primary carrier.
You may receive correspondence from HMS regarding coordination of benefit issues. Please remember that CareSource, as a Medicaid plan, is the payer of last resort after commercial health insurance carriers as well as Medicare.
We ask that you take measures to obtain third-party liability information from CareSource members. Please bill the appropriate carrier before billing CareSource.
