Medical Billing Services in Illinois

PRMS Billing Solutions runs complete billing and revenue cycle management for Illinois providers, from Chicago and the collar counties to Rockford, Peoria, and downstate. Illinois combines the nation's single most dominant Blue plan with a managed-Medicaid program that includes a county-run plan unique to Cook County. We handle eligibility, coding, claims, denials, AR, and credentialing across all of it, end to end.

Medicare billing in Illinois

Illinois Part B claims are processed by National Government Services (NGS), the Medicare Administrative Contractor for Jurisdiction 6. We submit to NGS daily and screen every claim against its local coverage determinations before it leaves. Medicare Advantage keeps growing in Chicagoland, with UnitedHealthcare, Humana, Aetna, and Blue Cross MA plans holding most of the enrollment, so we confirm MA status at eligibility on every Medicare patient.

Illinois Medicaid (HFS) billing

Illinois Medicaid is run by HFS (Healthcare and Family Services), with provider enrollment through the IMPACT system. Most members sit in HealthChoice Illinois managed-care plans: Meridian (Centene), Blue Cross Community Health Plans, Molina, Aetna Better Health, and, in Cook County, CountyCare, the county-operated plan that covers a huge share of Chicago's Medicaid population. Each MCO has its own portal and prior-auth list. We verify the member's plan before the visit and file to the right MCO with the right authorization.

Commercial payers we bill in Illinois

Blue Cross and Blue Shield of Illinois (HCSC's flagship) is the most dominant commercial payer of any large state, and its edits, PPO/HMO product split, and appeal tracks are core knowledge for Illinois billing. Around BCBSIL we bill UnitedHealthcare, Aetna, Cigna, Humana, and Health Alliance downstate. Illinois also produces steady workers' compensation volume under the Illinois fee schedule, which we bill and follow correctly for practices that see comp patients.

Specialties we serve across Illinois

We bill 25+ specialties across Illinois, including the fields that drive its outpatient market: internal medicine, cardiology, behavioral health, orthopedics, pain management, physical therapy, and urgent care.

Why Illinois practices choose PRMS

The Illinois leaks we close most often: HealthChoice claims filed to the wrong MCO (especially CountyCare vs Meridian mix-ups in Cook County), BCBSIL denials that never get appealed, and IMPACT enrollment gaps that silently stop payment. Our team works the Illinois payer mix daily and reports weekly, so you always know where every dollar sits. Credentialing with HFS/IMPACT, BCBSIL, and every major Illinois payer is free for billing clients.
