Common Illinois denials and how we prevent them
Past the 180-day limit
HFS will not pay initial or resubmitted claims received more than 180 days after the date of service unless an exception applies. We submit promptly and watch every resubmission.
Coordination of benefits
When Medicaid is secondary, the clock runs from the primary payer's decision. We post primary payments quickly and send the secondary claim right away.
Managed care authorization
HealthChoice Illinois plans set their own authorization rules. We check them before the visit and track every request.
