Florida presents one of the most complex and dynamic medical billing environments in the United States. With over 4.2 million Medicaid enrollees, one of the largest Medicare Advantage markets in the country, a massive dual-eligible population, and a commercial insurance landscape dominated by Florida Blue alongside major national carriers — providers in Florida face a multi-layered reimbursement structure that demands state-specific expertise at every level.
The most significant development in recent Florida billing history is the February 2025 launch of SMMC 3.0 — the third generation of Florida’s Statewide Medicaid Managed Care program, now fully operational in 2026 with new contracts through 2030, a restructured nine-region geographic framework, and virtually all Medicaid recipients enrolled in managed care plans. For providers still operating on pre-SMMC 3.0 workflows, the risk of misdirected claims, out-of-network denials, and credentialing gaps is significant.
This guide covers everything Florida providers need to know about medical billing, coding, and credentialing in 2026 — including the SMMC 3.0 structure, major MCO plans, timely filing limits, AHCA enrollment, and the 2026 changes affecting every Florida practice.
Part 1: Understanding Florida Medicaid — The SMMC 3.0 Structure
How Florida Medicaid Is Structured
Florida Medicaid is administered by the Florida Agency for Health Care Administration (AHCA). Billing and claims are processed through the Florida Medicaid Management Information System (FMMIS). Nearly all Medicaid recipients in Florida receive their benefits through the Statewide Medicaid Managed Care (SMMC) program — fee-for-service Medicaid now covers only a small fraction of the Medicaid population.
Under SMMC, Florida is divided into 9 geographic regions (A through I). The MCOs available to patients vary by region — a plan operating in Miami-Dade may not operate in Tallahassee. Providers must know which plans are active in their specific region and contract with each one independently.
SMMC 3.0 launched February 1, 2025 — replacing the previous SMMC 2.0 contracts with new plan agreements running through 2030. This launch brought:
- New MCO contracts with updated reimbursement structures and performance standards
- Stronger emphasis on behavioral health integration
- Value-Based Purchasing (VBP) requirements for MCOs
- New after-hours access standards for primary care providers
- Restructured nine-region geographic framework replacing the previous eleven-region structure
The Four Components of SMMC
Florida’s SMMC program covers four distinct program components. Each serves a different population and operates under different billing rules.
1. Managed Medical Assistance (MMA)
Who it covers: The majority of Florida Medicaid recipients — low-income children, families, pregnant women, individuals with disabilities, and adults who qualify for standard Medicaid benefits
What it covers: Comprehensive medical benefits including physician services, hospital care, preventive services, behavioral health, prescriptions, and most outpatient services
How it works: MMA members are auto-assigned to a health plan or choose one from those available in their region. Each plan assigns or the member selects a Primary Care Provider (PCP) who coordinates all care
Key billing rule: All standard medical services for MMA members go to the member’s MCO — not to AHCA fee-for-service. Prior authorization requirements vary significantly by MCO and service type
2. Long-Term Care (LTC)
Who it covers: Florida Medicaid recipients age 18 and older who meet a nursing facility level of care and need long-term services and supports — including nursing facility residents, and individuals receiving home and community-based services
What it covers: Nursing facility services, assisted living, adult day care, personal care, home health, and other LTSS. LTC does NOT cover acute medical services — those remain under MMA or Medicare
How it works: LTC eligibility is determined by DOEA/CARES (Community Aging and Retirement Services) for medical eligibility and DCF for financial eligibility. LTC has a waitlist for home and community-based services
Key billing rule: LTC covers long-term care services only. Acute medical services for LTC members are covered by Medicare (if dual-eligible) or by their MMA plan — not by the LTC plan. Routing an acute medical claim to an LTC plan will result in denial
3. Dental Program
Who it covers: Most Florida Medicaid recipients who were previously in fee-for-service dental or SMMC dental
What it covers: Scheduled dental services — routine exams, cleanings, fillings, extractions, and similar preventive and restorative dental care
How it works: Dental plans are separate from MMA health plans — a member’s MMA plan does not cover scheduled dental services. Dental plans are responsible for their own provider networks and billing processes
Key billing rule: Dental services bill to the member’s dental plan, not their MMA plan. MMA plans remain responsible for transportation to dental appointments, prescription drugs for dental care, and non-scheduled hospital dental visits only
4. ICMC — Intellectual and Developmental Disabilities Comprehensive Managed Care
Who it covers: Florida Medicaid recipients with intellectual and developmental disabilities (I/DD)
What it covers: Comprehensive medical and specialized support services for individuals with I/DD
How it works: Separate MCO network specifically contracted to serve I/DD populations
Key billing rule: ICMC members require specific MCO routing and prior authorization processes distinct from standard MMA
Major SMMC 3.0 MMA MCO Plans in 2026
Under SMMC 3.0, the following MCOs are active in Florida’s MMA program. MCO availability varies by region — confirm which plans operate in your specific service area:
| MCO | Programs | Coverage Area | Provider Services |
|---|---|---|---|
| Sunshine Health (Centene) | MMA | Most regions statewide — largest MCO in FL | 1-844-477-8313 |
| Simply Healthcare (Anthem/Elevance) | MMA / LTC | South and Central Florida — growing fast | Available via provider portal |
| WellCare / Staywell (Centene) | MMA | Multiple regions — separate from Sunshine despite same parent | Available via provider portal |
| Molina Healthcare of Florida | MMA / LTC (Miami-Dade and Monroe) | Strong South Florida presence | Available via Molina portal |
| Humana Medical Plan / Humana Healthy Horizons | MMA / LTC | Statewide — strong dual-eligible focus | Available via Availity |
| Aetna Better Health of Florida (CVS Health) | MMA / LTC | Select regions — limited network | Available via provider portal |
| AmeriHealth Caritas Florida | MMA / LTC | Select regions | Available via provider portal |
| Community Care Plan (Memorial Healthcare) | MMA | Broward County only | Available via provider portal |
| Prestige Health Choice | MMA | Select regions | Available via provider portal |
| Clear Health Alliance | MMA | HIV/AIDS population focus | Available via provider portal |
| Children’s Medical Services Health Plan | MMA (children with special needs) | Statewide | Available via provider portal |
⚠️ Critical Note on Centene Plans: Sunshine Health and WellCare/Staywell are both Centene subsidiaries operating in Florida — but they are completely separate plans with separate payer IDs, separate credentialing processes, and separate authorization requirements. Being contracted with Sunshine Health does NOT mean you are contracted with WellCare. Enroll with each separately.
For LTC plans specifically: Florida Community Care (FCC) and Humana Medical Plan are the only two plans with a full statewide footprint across all 9 regions. Other LTC plans — Aetna Better Health, Simply Healthcare, Sunshine State, AmeriHealth Caritas — operate in select regions only.
⚠️ Always verify payer IDs with your clearinghouse before submitting to any Florida MCO. Payer IDs vary by clearinghouse platform and may differ from published general references. Contact your clearinghouse provider support to confirm the correct payer ID for each Florida Medicaid MCO on your specific platform before submitting the first claim.
Part 2: How to Verify Eligibility in Florida
Florida Medicaid Eligibility Verification
Florida Medicaid eligibility is verified through two primary channels:
FMMIS Portal (Florida Medicaid Management Information System): Available at mymedicaid-florida.com. Allows providers to verify eligibility, confirm MCO enrollment, and check patient benefit status. This is the primary state-level verification tool.
Availity: Most Florida SMMC MCOs use Availity as their primary provider portal for eligibility verification, prior authorization, and claims submission. Running eligibility through Availity provides real-time MCO enrollment confirmation across multiple plans simultaneously.
Critical Eligibility Warning — SMMC 3.0 Auto-Assignment
Under SMMC 3.0, beginning February 2025, AHCA began auto-assigning virtually all eligible Florida Medicaid recipients into a managed care plan. This means:
- Nearly every Medicaid patient who walks into your office is enrolled in an MCO
- If you are not contracted with their plan, you are billing as an out-of-network provider, and most plans don’t cover out-of-network for routine services
- Being enrolled with AHCA but uncontracted with an MCO creates a specific billing problem — you have a valid Medicaid provider number, but the plan will not process your claims as in-network
- MCO assignments change — patients can be auto-reassigned between plans. Always verify at every visit
Always verify which MCO the patient is enrolled with at every single visit. Do not assume continuity from a prior visit.
Special Eligibility Scenarios in Florida
Dual-Eligible Patients (Medicare + Medicaid): Florida has one of the largest dual-eligible populations in the country. For dual-eligible patients:
- Medicare is always primary — bill Medicare first
- Florida Medicaid (MMA plan) is secondary — submit the Medicare remittance to the MMA MCO for any remaining patient liability
- Confirm whether the patient is in a standard Medicare + Medicaid arrangement or a D-SNP (Dual Special Needs Plan) — D-SNP plans coordinate both benefits through a single plan and have their own billing requirements
Populations Exempt from SMMC Mandatory Enrollment: Florida Medicaid recipients not eligible for MMA include women eligible only for family planning services, women eligible through the breast and cervical cancer services program, persons eligible for emergency Medicaid for aliens, and Medicaid-Medicare dual eligible whose Medicaid benefits are limited. These populations may remain in fee-for-service and bill AHCA/FMMIS directly.
Part 3: Claim Filing Limits — Florida MCOs and Commercial Payers
Timely filing is one of the most permanent and unrecoverable denial types. In Florida, each MCO sets its own filing deadline — and under SMMC 3.0, these deadlines must be understood plan by plan.
⚠️ Important Warning on Timely Filing Limits: Deadlines listed below reflect published general guidelines current as of 2026. Your specific provider contract governs your actual filing deadline. Always verify timely filing requirements in your signed provider agreement with each payer. Contracted terms may differ from published general policies.
Florida Medicaid and MCO Timely Filing Limits
| Payer | Timely Filing Limit | Notes |
|---|---|---|
| Florida Medicaid FFS (AHCA) | 12 months from date of service | Applies only to the small FFS population not in SMMC |
| Sunshine Health (Centene) | 180 days from date of service | Largest MCO in Florida — confirm with your contract |
| WellCare / Staywell (Centene) | 180 days from date of service | Separate from Sunshine despite same parent — verify contract |
| Simply Healthcare (Anthem) | 120 days from date of service | Verify with your specific contract |
| Molina Healthcare of Florida | 120 days from date of service | Consistent across most Molina lines of business |
| Humana Medical Plan | 90 days from date of service | One of the shortest windows — requires prompt submission workflow |
| Aetna Better Health of Florida | 120 days from date of service | Verify with your contract |
| AmeriHealth Caritas Florida | 180 days from date of service | Verify with your contract |
| Community Care Plan | Verify with plan | Broward County only — confirm directly |
| Florida Medicaid Dental Plans | Verify with plan | Each dental plan has its own filing window |
Commercial and Medicare Timely Filing Limits in Florida
| Payer | Timely Filing Limit | Notes |
|---|---|---|
| Medicare Part A and Part B | 12 months from date of service | Federal requirement — measured by receipt date |
| Medicare Advantage plans | 90–120 days from date of service | MA plans set their own deadlines — significantly shorter than original Medicare |
| Florida Blue (BCBS of Florida) | 180 days (HMO) / 12 months (some PPO) | Largest commercial carrier in Florida — verify plan type |
| UnitedHealthcare (commercial) | 90–180 days from date of service | Varies by employer contract — verify your agreement |
| Aetna (commercial) | 120 days from date of service | Some employer and MA plans allow up to 1 year |
| Cigna (commercial) | 90–180 days from date of service | Varies by plan type |
| Humana (commercial / Medicare Advantage) | 90 days from date of service | Shortest commercial window — requires active A/R management |
| Oscar Health (ACA marketplace) | 180 days from date of service | Verify with your contract |
Florida-Specific Timely Filing Note — Disaster Extensions
During a declared disaster period, Florida AHCA automatically extends timely filing deadlines for affected counties. Florida is subject to frequent hurricane declarations — when a state or federal disaster is declared for specific counties, AHCA extends Medicaid timely filing deadlines for providers in those counties for the duration of the declared period. Monitor AHCA announcements during active disaster declarations and document any claim submissions affected by a disaster period using AHCA Form 2040 — Timely Filing Certification Statement.
Part 4: 2026 Updates Every Florida Provider Needs to Know
1. SMMC 3.0 — Now Fully Operational
On February 1, 2025, AHCA implemented the new SMMC 3.0 program, entering into new contracts with health and dental plans through 2030. As of 2026, SMMC 3.0 is the operating framework for all Florida Medicaid managed care. Key implications:
- Providers who have not yet verified their network participation status under the new SMMC 3.0 contracts should do so immediately — old SMMC 2.0 contracts are no longer valid
- Review new reimbursement, prior authorization, and reporting requirements under SMMC 3.0 and ensure your billing and claim submission processes align with the new plan structures.
- Build a tracking system for clients’ eligibility changes, plan assignments, and network participation — because claims may be delayed or denied if a client’s plan changes unexpectedly.
2. AHCA Portal System Transition — April 2026
A significant AHCA portal transition occurred in April 2026. Providers with pending AHCA applications or open renewals in the current Florida Medicaid system should complete them before the April 2026 new system launch — anything left incomplete in the old portal creates migration complications that extend the AHCA enrollment timeline and delay SMMC credentialing start.
If your practice submitted any AHCA enrollment or revalidation applications in late 2025 or early 2026 that were not yet processed, confirm their status directly with AHCA to ensure they migrated correctly to the new system.
3. After-Hours Access Standards — Effective End of 2026
By the end of the 2026 contract year, the negotiated performance standards require after-hours primary care provider availability from at least 50 percent of a plan’s participating MMA primary care providers in regions A, B, E, G, H, and I, and at least 45 percent in regions C and D.
For primary care practices contracted with MMA plans, this standard affects network adequacy requirements. MCOs are responsible for ensuring their networks meet these thresholds — practices that offer after-hours availability are more attractive as MCO network partners and may have stronger leverage in contract negotiations.
4. January 2026 — Florida Blue S Code Elimination
Effective January 2026, Florida Blue eliminated certain S codes from their accepted code set. Practices billing Florida Blue should audit their charge master for any S codes that may have been active and confirm current accepted billing codes with the updated Florida Blue provider manual.
5. Behavioral Health Integration Under SMMC 3.0
SMMC 3.0 placed significant emphasis on integrating behavioral health services into Medicaid managed care. For practices providing behavioral health, substance use disorder treatment, or integrated primary care and behavioral health services:
- Confirm your SMMC 3.0 MCO contracts include behavioral health service coverage
- Review updated prior authorization requirements for behavioral health services under each MCO
- SMMC 3.0 expanded telehealth coverage for behavioral health — confirm your telehealth billing aligns with each plan’s current policies
6. Molina CMS Contract — Children’s Medical Services
Molina Healthcare of Florida was awarded the sole contract to provide SMMC services to Florida’s children and youth with special healthcare needs under the Title XIX and Title XXI Children’s Medical Services (CMS) Program, expecting to serve approximately 120,000 enrollees through December 31, 2030. Pediatric and specialty practices serving children with complex medical needs should prioritize Molina enrollment for the CMS population.
Part 5: Commercial Payer Landscape in Florida
Florida’s commercial insurance market is among the largest and most competitive in the country, driven by its large population, significant retiree demographic, and growing workforce.
Major commercial payers in Florida:
- Florida Blue (BCBS of Florida / GuideWell) — the dominant commercial insurer in Florida, serving all 67 counties with commercial, Medicare Advantage, and SMMC Medicaid MCO product lines serving 14 million or more members. Any Florida practice must prioritize Florida Blue credentialing above all other commercial carriers
- UnitedHealthcare — major employer-sponsored plan presence statewide; also significant Medicare Advantage market share
- Aetna (CVS Health) — strong commercial and Medicare Advantage presence, separate from Aetna Better Health (the Medicaid MCO)
- Cigna — primarily metropolitan areas — Miami, Orlando, Tampa, Jacksonville
- Humana — one of the strongest Medicare Advantage presences in Florida, reflecting the state’s large senior population
- Oscar Health — growing ACA marketplace presence in South Florida
- Molina Healthcare — growing commercial presence alongside Medicaid operations
Regional commercial market notes:
- South Florida (Miami-Dade, Broward, Palm Beach) — Florida Blue, UnitedHealthcare, Aetna, and Molina are all major players; Humana Medicare Advantage is especially dominant in the large retiree population
- Central Florida (Orlando, Orange County) — Florida Blue and UnitedHealthcare lead; Simply Healthcare and Sunshine Health are significant for Medicaid
- Tampa Bay (Hillsborough, Pinellas) — Florida Blue dominant commercial carrier; large Medicare Advantage market
- Northeast Florida (Jacksonville, Duval County) — Florida Blue is headquartered in Jacksonville and has particularly strong market dominance
Part 6: Credentialing in Florida — AHCA Enrollment and What Makes Florida Different
Step 1 — AHCA Enrollment: The Gateway to Florida Medicaid
All providers who want to bill Florida Medicaid — in any form — must first enroll through AHCA’s FMMIS portal. AHCA enrollment is the foundational prerequisite. Without it, no Florida Medicaid claims can be submitted and no MCO contracting can begin.
Key AHCA enrollment requirements:
- Active NPI (National Provider Identifier) — required before beginning enrollment
- Valid Florida state license from the appropriate licensing board
- Level 2 background screening — required for many Florida provider types, including physicians, NPs, and other licensed healthcare professionals. This involves fingerprinting and a criminal history check — budget 2 to 4 weeks for this step alone as it cannot be expedited
- Owners and administrators of group practices also face Level 2 screening requirements on top of standard provider checks
AHCA enrollment processing time: Most applications take 30 to 90 days, depending on completeness and provider type. Complete applications are processed significantly faster.
The April 2026 portal transition: As noted in Part 4, AHCA implemented a new portal in April 2026. Any enrollment applications submitted in the old system that were not fully processed before the transition should be confirmed with AHCA directly.
Step 2 — Separate MCO Credentialing After AHCA Enrollment
This is the most important and most frequently misunderstood step in Florida Medicaid credentialing:
AHCA enrollment does NOT automatically enroll you with any MCO. Many Florida physicians mistakenly assume that once they are enrolled with Medicaid, they are automatically contracted with managed care plans. That is not the case. After approval through AHCA, providers must still contract individually with managed care organizations such as Sunshine Health, Simply Healthcare, or Humana Healthy Horizons. Each MCO has its own credentialing process and deadlines.
For each MCO you want to participate with:
- Complete an active CAQH ProView profile — MCO credentialing typically requires an active CAQH ProView profile. Most pull credentials directly from CAQH rather than requesting separate documentation. An outdated CAQH profile delays MCO contracting the same way a deficient AHCA application delays enrollment.
- Submit a network participation request through each MCO’s provider portal
- Complete MCO-specific credentialing review — typically 60–90 days per plan
- Sign a participating provider agreement
- Confirm network activation effective date before submitting the first claim
Most Florida SMMC MCOs use Availity as their primary provider portal for eligibility verification, prior authorization, and claims submission. Ensure your practice is registered in Availity before approaching MCO credentialing.
Florida State Licensing
All providers practicing in Florida must hold a valid license from the appropriate Florida licensing board:
- Physicians (MD): Florida Board of Medicine — flhealthsource.gov
- Physicians (DO): Florida Board of Osteopathic Medicine — flhealthsource.gov
- Nurse Practitioners: Florida Board of Nursing — flhealthsource.gov
- Physician Assistants: Florida Board of Medicine
- All other licensed providers: Florida Department of Health (DOH) — floridahealth.gov
Florida physician licenses renew every two years. License expiration stalls all active credentialing applications — build renewal reminders at least 90 days before expiration.
Florida Blue Credentialing — Specific Requirements
Given Florida Blue’s dominant market position, dedicated credentialing guidance is warranted:
- Florida Blue uses Medversant as its named credentialing verification organization (CVO) for individual providers
- Facilities use WebCVO — not CAQH — for Florida Blue facility credentialing
- Florida Blue has frequent panel closures in certain specialties and regions — confirm whether the specialty panel you are applying to is open before submitting
- The April 2026 quarterly directory attestation enforcement under CAA 2021 is now active — providers must attest their directory information with Florida Blue quarterly or face removal from the provider directory
Florida Credentialing Timeline Expectations
| Payer / Enrollment | Typical Timeline |
|---|---|
| AHCA (Florida Medicaid enrollment) | 30–90 days |
| Level 2 background screening | 2–4 weeks (concurrent with AHCA) |
| Florida SMMC MCOs (each) | 60–90 days after AHCA approval |
| Florida Blue (commercial) | 60–90 days |
| UnitedHealthcare (commercial) | 60–90 days |
| Aetna / Cigna / Humana | 90–120 days |
| Medicare PECOS | 60–90 days |
For a new practice in Florida needing full network participation, begin credentialing a minimum of 120 days before the intended first date of patient care — and closer to 150 days if AHCA enrollment and Level 2 background screening need to be completed from scratch.
What Florida Providers Should Do Right Now
For SMMC 3.0 and Medicaid billing:
- Verify your network participation status under the new SMMC 3.0 contracts — old SMMC 2.0 contracts are no longer valid
- Confirm your AHCA enrollment is active and your FMMIS provider record reflects your current practice location and specialty
- If you submitted an AHCA application that was pending during the April 2026 portal transition — confirm its status directly with AHCA
- Run FMMIS or Availity eligibility verification at every patient visit — SMMC 3.0 auto-assignment means patients may change plans without notice
- Build a tracking system for MCO assignment changes as recommended by AHCA under SMMC 3.0
For credentialing:
- Confirm CAQH ProView profile is current and re-attested — all Florida SMMC MCOs require it and most pull credentials directly from CAQH
- If you are not yet contracted with Sunshine Health — start there first. It is the largest MCO in Florida and covers most regions
- Remember Sunshine Health and WellCare/Staywell are separate Centene plans requiring separate enrollment
- Audit all Florida Board of Medicine and Board of Nursing license expiration dates for every provider in your practice
- For Florida Blue: confirm quarterly directory attestation is completed under the April 2026 CAA enforcement
For timely filing management:
- Build a payer-specific timely filing calendar — Humana’s 90-day window requires the most aggressive submission workflow
- For claims submitted during any Florida declared disaster period, document submission attempts and use AHCA Form 2040 for timely filing exceptions if needed
- For dual-eligible patients, confirm whether they are in a D-SNP or standard Medicare + Medicaid secondary arrangement — each has different claim routing
For commercial payers:
- Prioritize Florida Blue credentialing above all other commercial carriers — it is the dominant plan in all 67 Florida counties
- For South Florida and Medicare-heavy patient populations, prioritize Humana Medicare Advantage credentialing alongside Florida Blue
Final Thoughts
Florida Medicaid in 2026 is defined by SMMC 3.0 — a fully managed care environment where nearly every Medicaid patient is in an MCO, and where provider revenue depends on being correctly credentialed, correctly routing claims, and actively managing relationships with multiple MCO plans simultaneously.
