Chicago sits in Cook County, where Medicaid runs through six HealthChoice Illinois managed care plans and a large share of patients carry commercial or Medicare Advantage coverage. Billing a claim to the wrong plan is one of the fastest ways to lose a payment here, so Qualigenix verifies each patient's plan before the claim goes out. For the statewide filing windows and payer rules that apply beyond the county, see our medical billing services in Illinois. We bill all payers. That means the Cook County Medicaid plans, Medicare through National Government Services, and the commercial carriers your patients bring in. You keep your current system, and we work claims inside it. For how we handle Illinois Medicaid claims statewide, our state page lays out the 180-day filing rule and how we track to it.
Qualigenix runs the full billing cycle for Chicago practices: eligibility checks, charge capture, coding review, claim scrubbing, submission, payment posting, denial appeals and A/R recovery. We file to the six HealthChoice Illinois plans serving Cook County,
to Medicare through the state's contractor, and to every commercial payer, then track each claim to payment. Our Qualigenix medical billing services cover all of it under one team.
Cook County is the one county in Illinois with a county-only Medicaid plan on top of the statewide ones, so a Chicago practice bills more plans than most. Qualigenix files to each one on its own rules.
Cook County patients enroll in one of six HealthChoice Illinois plans: Aetna Better Health of Illinois, Blue Cross Community Health Plans, Humana, Meridian, Molina, and CountyCare Health Plan, which serves Cook County only. Qualigenix bills each plan to its claim format and timely-filing window so a Chicago practice collects from all of them.
CountyCare is Cook County's largest Medicaid managed care plan and runs only here, so many Chicago practices see it when they see no other Medicaid MCO. Qualigenix bills CountyCare directly and tracks each claim against Illinois Medicaid's 180-day filing limit.
Illinois Medicaid expects claims within 180 days of the date of service, and the same rule carries across every HealthChoice plan. Our Illinois medical billing page covers how Qualigenix tracks that window for every Chicago claim.
These are company-wide figures across the practices Qualigenix bills for, not Chicago-only numbers.
