Coding and claim mechanics are national. What changes at a state line is everything around them: who adjudicates your Medicare claims and hears your appeals, what your Medicaid program is called and whether a commercial plan sits in front of it, whether an auto injury is the health plan's problem or the auto carrier's — and how a billing company is permitted to charge you.
In Illinois, Medicare is administered by National Government Services (J6). Medicaid runs as HealthChoice Illinois, delivered largely through commercial managed care plans — so most Medicaid claims are adjudicated by an insurer with its own filing window and authorization rules rather than by the state.
Illinois is a tort state for auto injuries, so standard coordination of benefits applies rather than a no-fault carrier taking first position.
White Glove Medical Billing is a medical billing, coding, and revenue cycle company — not a healthcare provider and not a law firm. All coding is performed by certified coders from your providers' documentation; the clinical record and the certification of medical necessity remain the provider's.

Appeals in Illinois
National Government Services (J6) is who hears the first level of appeal for a Medicare denial here. That matters practically: an appeal argument that works with one contractor generally works across every state it covers, and local coverage determinations mean the same service can be covered in Illinois and not one state over.
What we handle for Illinois practices
- Medical coding by certified coders, from your documentation
- Charge entry, claim scrubbing, and electronic submission
- Clearinghouse rejection follow-up and denial management
- Payment posting reconciled to your bank deposits
- Aged A/R worked by recoverability, not by date
- Coordination of benefits sequenced across primary and secondary coverage
- Patient statements, payment plans, and a billing support line
A note on Illinois business taxes
Not a service we sell, and not advice — but a practice is still a business with a state footprint, and it comes up often enough to be worth stating. Illinois administers sales tax through the Illinois Department of Revenue. Most clinical services are not taxable, but retail sales — supplements, cosmetics, optical, DME sold rather than billed — frequently are. Employer registration runs through the Illinois Department of Employment Security, and the entity itself is registered with the Illinois Secretary of State. Your CPA owns all of it; we mention it because the retail side of a practice is where it usually surfaces.
We work the claims. You practice medicine.
Coding, claim submission, denial management, and A/R follow-up — with nothing left for your front desk to chase.

Both models are available here, and which one we use is settled in writing before any work begins rather than assumed.
Why Illinois is different. Illinois treats some percentage arrangements as fee splitting and permits others subject to conditions. Our pricing here is set accordingly — this describes what we charge, not what you are permitted to do, and it is not legal advice.

Every ongoing engagement carries a minimum monthly fee of $500. It exists so a new or small practice can be served properly rather than quoted a percentage that does not cover the work.
What changes the work in Illinois
- Medicare contractor
- National Government Services (J6)
- Claims for Illinois providers are adjudicated here, and this is who hears the first level of appeal.
- Medicaid program
- HealthChoice Illinois
- Delivered largely through commercial managed care plans, so most Illinois Medicaid claims go to a health plan rather than to the state.
Illinois shares its Medicare contractor with Minnesota and Wisconsin, so an appeal that works in one usually works in the others.

What we report every month
- Days in A/R — How long money takes to arrive.
- A/R over 90 days — What share of what you are owed is going stale.
- Clean claim rate — How often a claim is paid without rework.
- Net collection rate — Of what was collectable, how much we collected. The number that grades the whole engagement.
- Denial rate by reason — Grouped by cause, so it points at a fix rather than a total.
- Charge lag — Days from date of service to claim submission — often your number to fix rather than ours, which is exactly why you can see it.

Illinois — Frequently Asked Questions
Which Medicare contractor covers Illinois?
+
National Government Services (J6). That is who adjudicates your Medicare claims, publishes the local coverage determinations that bind you, and hears a redetermination.
Is Illinois Medicaid managed care?
+
HealthChoice Illinois is delivered largely through commercial managed care plans. Nationally about 78% of Medicaid beneficiaries are in comprehensive managed care, and five companies account for roughly half of that enrollment — so "billing Medicaid" here usually means billing a commercial insurer.
How do you price in Illinois?
+
Illinois treats some percentage arrangements as fee splitting and permits others subject to conditions. Our pricing here is set accordingly — that describes what we charge, and your own position is a question for your counsel rather than for us.
Do we have to be in Illinois to work with you?
+
No — we work remotely with practices in all 50 states and DC. What matters is that somebody is tracking Illinois's rules against your actual claims, which is what this page is for.
