Cardiology billing services in Illinois

Sources checked: . Sources and review scope.

Cardiology billing services in Illinois start with National Government Services (NGS), your Medicare contractor for jurisdiction J6. Its published coverage policies are one part of Medicare claim requirements. Policies can overlap across contractors, so payment under one contractor doesn't guarantee payment under another. We bill cardiology only, at 3% of collections with no contract.

How NGS pays cardiology in Illinois

NGS processes Medicare claims for jurisdiction J6. That covers Illinois, Minnesota and Wisconsin.

NGS writes its own local coverage policies for echo, nuclear imaging and cardiac monitoring. They list the diagnoses that support a study and what the note has to show. A study that pays under one contractor can be denied under another.

We check the applicable policy before filing. If documentation appears incomplete, we flag it for the practice to review before submission. Only the treating clinician can determine or change clinical documentation.

Illinois plan names and billing

Plans encountered in Illinois include Blue Cross and Blue Shield of Illinois, UnitedHealthcare, Aetna, Cigna and Humana. Product, network and contract terms vary; verify eligibility and the applicable plan requirements rather than assume statewide share or identical coverage.

HealthChoice Illinois is the state's Medicaid managed-care program, with plan availability that varies by county. We check the member's current plan and follow its provider instructions; not every Medicaid member or service necessarily follows the same route.

Cardiology practices we serve in Chicago, Peoria, Springfield, Rockford

We're built for independent practices of 1 to 10 cardiologists with imaging in the office. That means echo and vascular labs, a nuclear camera, monitors and device checks.

Medicare pays Illinois by locality. Chicago, suburban Chicago, East St. Louis and the rest of the state each carry their own rates. So the same echo pays differently in Chicago and Peoria. We post each payment against your locality's rate, not a state average.
