Wisconsin’s Medicaid program occupies a unique position in the national landscape. The state is one of a small number that chose not to expand Medicaid under the ACA — but unlike most non-expansion states, Wisconsin eliminated the coverage gap entirely by obtaining a federal waiver to cover all adults with incomes up to 100% of the Federal Poverty Level. Adults between 100% and 138% FPL — the population that would be covered under standard ACA expansion — are directed to the federal marketplace where they qualify for subsidized coverage with no premium gaps.
For Wisconsin providers, the practical result is a Medicaid program that is narrower in scope than full-expansion states but structured to eliminate coverage gaps through the marketplace pathway. The ForwardHealth system — Wisconsin’s integrated Medicaid portal — serves as the single interface for eligibility, enrollment, claims, and billing across BadgerCare Plus and all related programs. And Wisconsin’s long-term care landscape is one of the most complex in the country, with three parallel HCBS waiver pathways (Family Care, Family Care Partnership, and IRIS) serving different populations with distinct provider requirements.
Wisconsin Medicaid covers approximately 1.2 million Wisconsinites as of 2026 following the completion of the post-COVID enrollment unwinding. This guide covers everything Wisconsin providers need to know about medical billing, coding, and credentialing in 2026.
Medical billing in Wisconsin
BadgerCare Plus without full ACA expansion, but no coverage gap — Wisconsin covers adults to 100% FPL. Eight HMOs, ForwardHealth portal, private WC system, and strong regional commercial carriers.
Wisconsin did not expand Medicaid under the ACA — but it covers all adults with incomes up to 100% FPL, eliminating the coverage gap. Adults earning 100–138% FPL go to the federal marketplace with subsidies. No coverage gap exists in Wisconsin, but providers see marketplace commercial claims (not Medicaid) for the 100–138% FPL population. Income limits updated February 1, 2026.
Part 1: Wisconsin Medicaid Programs — BadgerCare Plus and Beyond
How Wisconsin Medicaid Is Structured
Wisconsin Medicaid is administered by the Wisconsin Department of Health Services (DHS) through its ForwardHealth program. The ForwardHealth interChange system is the Medicaid Management Information System (MMIS) that processes claims. The ForwardHealth Portal at forwardhealth.wi.gov is the provider interface for eligibility verification, claims submission, prior authorization, and enrollment.
Key contact: ForwardHealth Provider Services: 800-362-3002 (Monday–Friday, 7 a.m.–6 p.m. Central)
BadgerCare Plus — Primary Medicaid Program
BadgerCare Plus is Wisconsin’s primary Medicaid program for low-income residents. It covers:
- Children and pregnant women
- Parents and caretaker relatives
- Adults without children with incomes up to 100% FPL
- Childless adults covered through the federal 1115 waiver
What Wisconsin does NOT have: Wisconsin did not accept ACA Medicaid expansion. As a result, adults earning between 100% and 138% FPL do not qualify for BadgerCare Plus — they are directed to HealthCare.gov where they qualify for subsidized marketplace plans. This means providers treating patients in this income range will see marketplace/exchange commercial claims rather than Medicaid claims.
Income limits updated February 1, 2026 — slightly later than most states. FPL reference: 100% FPL ≈ $1,330/month for a single person in 2026.
Active BadgerCare Plus HMOs in 2026
Most BadgerCare Plus members receive benefits through a managed care HMO. Members in areas without HMO options receive fee-for-service coverage directly through ForwardHealth. HMO availability varies by county.
| HMO | Service Area |
|---|---|
| Anthem Blue Cross Blue Shield of Wisconsin | Statewide (most counties) |
| Dean Health Plan (SSM Health) | South-central Wisconsin (Dane County/Madison area) |
| Group Health Cooperative of South Central Wisconsin (GHC-SCW) | Madison area cooperative |
| MHS Health Wisconsin | Select regions |
| Molina Healthcare of Wisconsin | Select regions |
| Quartz Health Solutions | West and central Wisconsin |
| Security Health Plan of Wisconsin | North-central Wisconsin (Marshfield Clinic) |
| UnitedHealthcare of Wisconsin | Statewide (most counties) |
⚠️ Always verify payer IDs with your clearinghouse before submitting to any Wisconsin BadgerCare Plus HMO. HMO availability varies by county and payer IDs vary by clearinghouse platform.
HMO enrollment verification: Use the ForwardHealth Portal to confirm which HMO a BadgerCare Plus member is enrolled with before submitting claims. Claims submitted to the wrong HMO will be denied.
Key BadgerCare Plus Billing Rule
All claims submitted to a BadgerCare Plus HMO must include the same information required for Wisconsin Medicaid FFS billing — including the correct and complete BadgerCare Plus member ID number, billing and rendering NPIs, taxonomy code, and 9-digit zip code. BadgerCare Plus is always the payer of last resort — if the member has other insurance, that must be billed first.
Wisconsin Long-Term Care Programs
Wisconsin’s HCBS long-term care landscape is one of the most structured in the country, with three distinct pathways:
Family Care — the primary HCBS program for adults with physical disabilities, developmental disabilities, or adults 65+ who need long-term care support and services in the community
Family Care Partnership — integrates Medicare and Medicaid for dual-eligible adults needing LTSS; managed by the same MCOs as Family Care with the addition of Medicare coordination
IRIS (Include, Respect, I Self-Direct) — a self-directed alternative to Family Care where the member manages their own care budget and hires their own support workers; provider enrollment for IRIS is distinct from standard Medicaid enrollment
My Choice Wisconsin — administers Family Care and Family Care Partnership in the eastern Wisconsin counties; also manages IRIS in some regions
County option programs — Some Wisconsin counties offer their own HCBS programs. LTC-specific provider enrollment is through the ForwardHealth Portal with provider type codes specific to waiver services.
Other Wisconsin Medicaid Programs
| Program | Population |
|---|---|
| Wisconsin Medicaid for aged, blind, disabled | Seniors and people with disabilities exceeding BadgerCare Plus income but meeting non-MAGI rules |
| Medicaid Purchase Plan (MAPP) | Working adults with disabilities who can buy into Medicaid coverage |
| Katie Beckett | Children under 19 with long-term disabilities or complex medical needs — no parental income counting |
| Care4Kids | Children in out-of-home care in Kenosha, Milwaukee, Ozaukee, Racine, Washington, and Waukesha counties |
| Wisconsin Well Woman Program | Specific screenings for low-income women; breast and cervical cancer screening |
| HealthCheck | Wisconsin’s EPSDT program for comprehensive preventive well-child services |
Part 2: ForwardHealth Provider Enrollment
All providers billing Wisconsin Medicaid in any form must enroll through the ForwardHealth Portal at forwardhealth.wi.gov. Provider enrollment is managed through ForwardHealth interChange.
Provider enrollment helpline: 800-362-3002
Required enrollment elements:
- Active NPI
- Valid Wisconsin state license
- Taxonomy code matching the services provided and provider type
- Federal tax ID (EIN or individual SSN)
- 9-digit zip code for all service locations
Medicaid Wisconsin ID number: Providers receive a Wisconsin Medicaid provider ID number upon successful enrollment. This ID must be current and active for all service locations. The LTC waiver programs require separate enrollment and issue separate provider ID numbers.
Revalidation: Wisconsin Medicaid requires periodic provider revalidation. Providers who do not respond to revalidation notices within the required 30-day response window risk enrollment termination.
⚠️ ALERT: Medicaid payments have ended for providers of Medicaid waiver authorized services who did not obtain a Wisconsin Medicaid ID number. If your practice provides any waiver-authorized services, confirm your Wisconsin Medicaid ID is current and linked to your service locations.
HMO Contracting After ForwardHealth Enrollment
ForwardHealth enrollment authorizes FFS billing but does not automatically contract you with any BadgerCare Plus HMO. After enrollment:
- Contact each HMO’s provider relations department to initiate network participation
- Complete HMO credentialing (CAQH ProView required by most Wisconsin HMOs)
- Sign participating provider agreement
- Confirm network activation before submitting first BadgerCare Plus claim
Part 3: Eligibility Verification in Wisconsin
ForwardHealth Portal — Primary eligibility verification at forwardhealth.wi.gov. Provides real-time eligibility, HMO enrollment status, and program participation.
Phone: 800-362-3002 for eligibility questions
Key verification rules:
- Verify program AND HMO enrollment at every visit — BadgerCare Plus members can change HMOs and program status can change
- BadgerCare Plus is payer of last resort — verify any other insurance coverage before billing
- For LTC waiver patients — verify which waiver program and the care manager/MCO responsible

Part 5: Commercial Payer Landscape in Wisconsin
Wisconsin’s commercial insurance market features a mix of national carriers and strong regional plans with deep market penetration in specific geographic areas.
Anthem Blue Cross Blue Shield of Wisconsin — largest commercial carrier statewide. Also participates as a BadgerCare Plus HMO (Anthem Blue Cross Blue Shield of Wisconsin) and operates Medicare Advantage products. Priority credentialing for all Wisconsin practices.
WPS Health Solutions — Wisconsin’s own commercial insurer, headquartered in Madison. WPS offers commercial plans through its Wisconsin-based insurance subsidiary (distinct from its federal Medicare contracting operations). Strong employer-sponsored coverage presence particularly in state and local government employee benefits.
Dean Health Plan — commercial HMO affiliate of SSM Health (formerly Dean Medical Group), with strong market presence in the Madison/Dane County area. Dean also operates as a BadgerCare Plus HMO in south-central Wisconsin.
Quartz Health Solutions — regional commercial carrier serving west and central Wisconsin markets, formed through the merger of Unity Health Insurance and other regional plans.
Security Health Plan of Wisconsin — commercial HMO affiliated with Marshfield Clinic Health System, with strong presence in north-central Wisconsin. Dominant commercial carrier in the Marshfield, Wausau, Eau Claire corridor.
Group Health Cooperative of South Central Wisconsin (GHC-SCW) — consumer-owned cooperative health plan based in Madison. Non-profit model with strong membership loyalty. Participates in BadgerCare Plus.
Other significant payers:
- UnitedHealthcare — national commercial and Medicare Advantage presence
- Aetna — commercial presence particularly for large employer groups
- Cigna — commercial presence in metropolitan markets
- Humana — Medicare Advantage focused
Regional market notes:
- Milwaukee metro: Anthem BCBS and UnitedHealthcare dominant commercially; Molina and Anthem strong for BadgerCare Plus
- Madison (Dane County): Dean Health Plan and GHC-SCW very strong; WPS significant; competitive market
- Green Bay (Brown County): Anthem BCBS and Security Health Plan significant
- Eau Claire / Chippewa Falls: Security Health Plan and Quartz dominant
- Rural Wisconsin: Security Health Plan (north-central), WPS, and Anthem BCBS cover most rural markets
Part 6: Commercial Billing Rules and State Mandates
Wisconsin Prior Authorization — State OCI Requirements
For fully-insured commercial plans regulated by the Wisconsin Office of the Commissioner of Insurance (OCI):
- Standard PA determination: 30 calendar days
- Urgent PA determination: 72 hours
Wisconsin’s standard PA window of 30 days is broader than states like Ohio (10 days) — meaning Wisconsin commercial payers have more time to process PA requests. However, the 72-hour urgent timeline applies to time-sensitive requests.
Gold carding in Wisconsin: Wisconsin does not have a statutory gold carding law comparable to Ohio HB 122. However, providers can negotiate gold card provisions through individual contract negotiations with commercial payers. If your PA approval rate for specific services consistently exceeds 90%, discuss gold card provisions with each payer during contract renewal.
Wisconsin Mental Health Parity
Wisconsin’s mental health parity law requires mental health and substance use disorder benefits to be provided at parity with physical health benefits. Wisconsin aligns with federal MHPAEA requirements for group health plans. The OCI enforces parity complaints — providers who face systematic behavioral health authorization denials that would not apply to equivalent medical services should document denials and file OCI complaints when patterns emerge.
Wisconsin Workers’ Compensation
Wisconsin operates a private carrier workers’ compensation system — employers purchase WC coverage from private insurers, not a state fund (unlike Ohio’s BWC system). All Wisconsin employers with 3 or more employees must carry workers’ compensation coverage. Coverage is regulated by the Wisconsin Department of Workforce Development (DWD).
Key Wisconsin WC billing rules:
- Injured worker chooses their own treating physician for the first 90 days after injury — unlike many states where the employer directs initial care
- After 90 days, employer may direct care to specific providers unless the treating physician relationship is established
- Claims are managed by private WC insurance carriers — identify the carrier and claim number before billing
- Prior authorization requirements vary by carrier — confirm with the specific WC insurer before rendering non-emergency services
- WC is primary — do not bill health insurance for work-related injuries covered by WC
WC provider enrollment: Unlike Ohio BWC, Wisconsin WC does not have a separate state enrollment system. Providers who treat work-injured employees bill the specific private WC carrier directly.
Dominant WC carriers in Wisconsin:
- Travelers Insurance
- Liberty Mutual
- Employers Holdings
- WPS (Fond du Lac-based, operates commercial and WC in Wisconsin)
- Several regional specialty WC insurers
Part 7: Credentialing in Wisconsin

What Wisconsin Providers Should Do Right Now
ForwardHealth enrollment:
- Confirm your Wisconsin Medicaid provider ID is current and all service locations are enrolled
- If you provide waiver-authorized LTC services — verify your Medicaid ID is linked for waiver billing; unpaid claims have resulted from missing IDs
- Confirm HMO contracts are active with all BadgerCare Plus plans serving your patient population
Eligibility verification:
- Verify ForwardHealth HMO enrollment at every BadgerCare Plus patient visit — HMO assignment can change
- Confirm BadgerCare Plus is payer of last resort — bill any other insurance first
- For LTC patients — verify which waiver program and responsible MCO/care manager
Commercial billing:
- Prioritize Anthem BCBS Wisconsin credentialing above all other commercial carriers
- For Madison-area practices, prioritize Dean Health Plan and GHC-SCW as second and third commercial credentialing priorities
- For north-central Wisconsin practices, Security Health Plan is a critical credentialing priority
- Document WC claim numbers and carrier information before billing any workers’ compensation claim
State law compliance:
- Verify your PA submission workflow meets the Wisconsin OCI 72-hour urgent deadline
- Review behavioral health authorization denials for potential parity violations — OCI complaint is the Wisconsin enforcement mechanism
