Note: if your plan is an employer self-funded plan (most large-employer plans), Medicare, Medicaid, FEHB, TRICARE, or VA, the state insurance department is NOT the right route. Check the plan type on your member ID card before filing.
- No Surprises Act complaint (federal CMS) — emergencies, out-of-network at in-network facilities, air ambulance.
- Good Faith Estimate dispute — self-pay, when bill exceeds GFE by $400+.
- DOL EBSA — employer self-funded plan disputes.
Common Wisconsin bill issues
What to look for first.
The eight most common billing errors apply everywhere — but here's how to start in Wisconsin.
Compare to your EOB
If your provider balance doesn't match the patient responsibility on your insurer's EOB, that's a red flag. Read the EOB-mismatch guide.
Check the major CPT codes
Look up codes like 99285 (high-complexity ER), 99214 (office visit), 85025 (CBC). Upcoding is the #1 dispute reason.
Check for charity care
Aurora Health Care and other Wisconsin non-profit hospitals publish 501(r) financial assistance policies. 7-minute application guide.
Use the No Surprises Act
Emergency, out-of-network at in-network facility, or air ambulance? The federal protection applies to Wisconsin patients.
If self-pay, use the GFE rule
If your final bill is $400+ above your Good Faith Estimate, file a CMS dispute.
