Chicago is the third-largest healthcare market in the country, with major academic medical centers, a large public system run by Cook County Health and thousands of independent practices.
Medical Coder provides outsourced medical billing services in Chicago for independent practices and groups — from eligibility checks to final payment — so you get paid faster with fewer denials.
Chicago Medical Billing Built Around Illinois Payers
Most avoidable denials start with payer rules. For Chicago practices we work every major payer in Illinois:
- Medicaid: Illinois Medicaid, administered by the Department of Healthcare and Family Services (HFS), through HealthChoice Illinois plans such as Blue Cross Community Health Plans, Meridian, Molina, Aetna Better Health of Illinois and CountyCare in Cook County.
- Medicare: Part A and Part B claims through National Government Services (Jurisdiction 6), plus Medicare Advantage plans.
- Commercial plans: Blue Cross and Blue Shield of Illinois, UnitedHealthcare, Aetna, Cigna and Humana.
- TRICARE and VA Community Care for military families and veterans.
Illinois has payer rules of its own — see medical billing in Illinois for how we handle them.
Billing Challenges for Chicago Practices
Chicago practices bill BCBSIL, Medicaid managed care plans including CountyCare, and Medicare through NGS. We verify the right plan for every patient and appeal every incorrect denial.
