Medical Billing Services in Illinois

In Illinois, seeing Medicaid patients takes two separate steps: enrolling with the state through IMPACT, then contracting with each HealthChoice Illinois plan. Workers' comp is priced against a Commission fee schedule, and commercial claims fall under state prompt-pay rules. We bill remotely for Illinois practices and keep each of those processes moving.

  • IMPACT enrollment and separate HealthChoice Illinois plan contracts
  • Workers' comp paid at the lesser of charges or the IWCC schedule
  • Late-paying insurers and HMOs followed up under state prompt-pay rules

HealthChoice Illinois and IMPACT enrollment

Illinois Medicaid is run by the Department of Healthcare and Family Services (HFS), and most members receive care through its HealthChoice Illinois managed care program. Providers enroll in Illinois Medicaid online through the IMPACT provider enrollment system.

Enrollment alone does not let you see plan members. New providers credential through IMPACT and also need to contract with each HealthChoice Illinois plan individually. A practice that skips the plan contract finds its claims denied even though its state enrollment is active.

Practices we typically see in Illinois

Illinois practices that see Medicaid patients usually manage two layers of enrollment: the state record in IMPACT, and a contract with each HealthChoice Illinois plan whose members they treat. Keeping both current is often the difference between a paid claim and an eligibility denial.

Workers' compensation fee schedule in Illinois

The Illinois Workers' Compensation Commission maintains a medical fee schedule, and under Sections 8(a) and 8.2 of the Workers' Compensation Act the employer pays the lesser of the provider's actual charge or the fee schedule amount. Fee schedule amounts change periodically, so we price claims against the Commission's current schedule.

Insurance regulation and prompt payment in Illinois

The Illinois Department of Insurance works to make sure insurance companies, HMOs and other regulated entities follow state insurance laws. State law also obliges insurers and HMOs, as well as IPAs and PHOs, to pay claims promptly, and providers are owed interest when a claim is paid late.

The exact deadlines and interest calculations are set in statute and can change, so we track the current rule and use the Department's provider complaint process when a payer falls behind.

How remote billing works for practices in Illinois

We work remotely in your systems, IMPACT and payer portals. We use accounts your staff create for us, with access you can review at any time.

  1. Step 1: Audit IMPACT and plan contracts

    Each provider's IMPACT enrollment and HealthChoice Illinois plan contracts are checked before Medicaid visits are scheduled.

  2. Step 2: Price workers' comp to the schedule

    Work-injury claims are compared with the IWCC fee schedule so underpayments are caught.

  3. Step 3: Watch for late payments

    Commercial and HMO claims that pass the prompt-pay window are followed up, with interest where it is owed.

  4. Step 4: Escalate through the Department

    Persistent late payment is taken through the Department of Insurance provider complaint process.
