Medical Billing Services in Wisconsin
Billing, coding, credentialing and denial management for Wisconsin practices, with Medicare claims through National Government Services (Jurisdiction J6) and Wisconsin Medicaid handled by people who know the rules.
Medical billing for Wisconsin practices
Wisconsin's payer market is regional. Health systems such as Froedtert ThedaCare, Aurora, Marshfield Clinic and UW Health sit alongside regional plans like Quartz, Security Health Plan and Network Health, plus Anthem and UnitedHealthcare. Wisconsin Medicaid runs through ForwardHealth, and most BadgerCare Plus members are enrolled in a state-contracted HMO. Wisconsin did not adopt the federal Medicaid expansion, though BadgerCare Plus covers adults up to 100% of the poverty level. Medicare Part B claims go to National Government Services in Jurisdiction 6.
SFA Solutions works with Wisconsin practices remotely, from Milwaukee and Madison to Green Bay, Eau Claire and the rural north. We verify each patient's HMO assignment in ForwardHealth, submit most clean claims within 24 hours, and work denials from regional plans that each publish their own medical policies.

What Wisconsin billing involves
These are the programs and rules our team works with for Wisconsin claims.
Medicare
National Government Services · J6Wisconsin Part B claims are processed by National Government Services in Jurisdiction J6. Medicare's filing limit is 12 months from the date of service, and appeals start with a redetermination within 120 days of the initial decision.
Wisconsin Medicaid
Wisconsin Medicaid and BadgerCare Plus, administered by the Wisconsin Department of Health Services (DHS) under the ForwardHealth name
Portal: ForwardHealth Portal, operated by the state's fiscal agent, Gainwell Technologies, for provider enrollment, eligibility and fee-for-service claims
Medicaid managed care
Most BadgerCare Plus and Medicaid SSI members are enrolled in a state-contracted HMO chosen by county, with a mix of regional plans such as Network Health, Quartz and Security Health Plan and national plans such as Molina and UnitedHealthcare Community Plan. Long-term care is delivered through Family Care and other programs with separate managed care organizations.
Timely filing
365 days from the date of service for ForwardHealth fee-for-service claims; BadgerCare Plus HMOs set limits in their provider contracts.
Commercial and Medicare Advantage
Anthem Blue Cross and Blue Shield, UnitedHealthcare, Quartz, Security Health Plan, Network Health and Dean Health Plan are major commercial carriers, with strong regional differences. UnitedHealthcare, Humana and several regional plans lead Medicare Advantage.
Prompt pay law
Wisconsin's timely payment statute (Wis. Stat. Section 628.46) generally treats a claim as overdue if it is not paid within 30 days after the insurer receives written notice of the claim, and overdue payments accrue interest.
Nurse practitioners
Reduced practiceAANP lists Wisconsin as reduced practice. 2025 Wisconsin Act 17, enacted in August 2025 and effective September 1, 2026, replaces APRN certification with an APRN license and allows independent practice after 3,840 hours of APRN practice working with a physician or dentist, plus 3,840 hours of clinical nursing practice. Practices should confirm each NP's current license status with the Board of Nursing before credentialing, since payer files must match it.
Credentialing
Providers enroll with Wisconsin Medicaid through the ForwardHealth Portal, then contract and credential with each BadgerCare Plus HMO in their area. Most commercial plans pull from CAQH ProView, and regional plans often have their own network applications. Medicaid enrollment must be revalidated at least every five years.
Billing challenges Wisconsin practices face
HMO assignment by county
BadgerCare Plus members are assigned to HMOs that vary by county and can change. A claim sent to the wrong HMO or to fee-for-service will deny, so eligibility needs checking in ForwardHealth at every visit.
Regional plans with their own policies
Quartz, Security Health Plan, Network Health and other regional plans publish their own medical policies and authorization lists. A code that pays without review at one plan may need prior authorization at another.
Changing NP practice rules
Wisconsin's new APRN law changes how NPs are licensed and when they can practice independently. Credentialing files and payer enrollments need updating as NPs move to the new license and gain independent status.
