Alabama stands apart from virtually every other state covered in this series for one fundamental reason: it is one of the last states in the country that has not fully transitioned its primary Medicaid population to capitated Managed Care Organizations.

While states like Illinois, Texas, Florida, and Pennsylvania route most Medicaid claims through private MCOs — each with their own payer IDs, authorization rules, and billing portals — Alabama operates under a fundamentally different model. The vast majority of Alabama Medicaid billing flows through a single centralized fee-for-service system, managed by the state’s fiscal agent, with care coordination layered on top through a network of regional organizations called the Alabama Coordinated Health Network (ACHN).

For providers coming from managed-care-heavy states, this structure is refreshingly different in some ways and uniquely complex in others. There are no multiple MCO payer IDs to track, no plan-specific authorization systems to navigate, and no conflicting formularies between competing managed care plans. But there is a two-tier enrollment requirement — Medicaid enrollment AND a separate ACHN participation agreement — that catches many out-of-state practices and telehealth agencies off guard. And the ACHN bonus payment system rewards providers who understand how to participate correctly with meaningful additional revenue.

This guide covers everything Alabama providers need to know about medical billing, coding, and credentialing in 2026 — including how the ACHN model works, the 2026 fee schedule updates, provider enrollment requirements, eligibility verification, commercial payer landscape, and what makes Alabama different from every other state in this series.

Part 1: Understanding Alabama Medicaid — The ACHN Model

How Alabama Medicaid Is Structured

Alabama Medicaid is administered by the Alabama Medicaid Agency at medicaid.alabama.gov. Claims are processed by the state’s fiscal agent, Gainwell Technologies, through the Alabama Medicaid Interactive Web Portal.

Unlike most states, Alabama does NOT operate a traditional capitated managed care model for its primary Medicaid population. Instead, the state uses the Alabama Coordinated Health Network (ACHN) — a non-capitated, regional care coordination framework in which primary care providers coordinate care for assigned Medicaid recipients while continuing to bill fee-for-service to the state fiscal agent.

This distinction is critical: in Alabama, claims do not go to an MCO. They go to the state fiscal agent (Gainwell) — the same central entity for virtually all Medicaid fee-for-service billing. There are no MCO-specific payer IDs for the primary Medicaid population. One payer, one billing channel.

The Two-Tier Model: FFS Billing PLUS ACHN Coordination

While all billing routes through the centralized FFS system, providers who want to access enhanced rates and quarterly bonus payments must participate in the ACHN — which requires a separate enrollment agreement with the regional ACHN entity in addition to standard Alabama Medicaid enrollment.

This two-tier structure means:

Tier 1 — Medicaid FFS Enrollment: Required for any provider who wants to bill Alabama Medicaid for any service. All claims process through Gainwell at standard FFS rates.

Tier 2 — ACHN Participation Agreement: Required to access enhanced reimbursement rates, care coordination bonus payments, and full ACHN network participation. ACHN providers must execute a separate agreement with their regional ACHN entity — in addition to their Medicaid enrollment.

Critically: ACHN providers must complete agreements with both Medicaid and the ACHN in order to receive bonus and participation rates. A provider enrolled in Medicaid but not in the ACHN receives only the standard FFS rates — not the higher ACHN-enhanced rates and not the quarterly bonus payments.

Alabama Medicaid Programs

Alabama operates several distinct programs within its Medicaid framework:

ACHN (Alabama Coordinated Health Network): The primary care coordination program for Alabama’s general Medicaid population. PCPs and specialty providers participate in the ACHN through regional entities organized across the state. ACHN participation comes with enhanced rates and quarterly bonus payments tied to quality and cost-effectiveness metrics.

ALL Kids — Alabama’s CHIP Program: Alabama’s Children’s Health Insurance Program serves children in families whose income is too high to qualify for Medicaid. ALL Kids operates as a commercial-style insurance product — it has its own enrollment, its own premium structure (for some income levels), and its own billing processes separate from standard Alabama Medicaid.

ICN (Integrated Care Networks): A managed care component for Alabama’s aged and disabled Medicaid population — individuals who qualify for both long-term care and medical services. The ICN model has a managed care structure distinct from the ACHN’s FFS-plus-coordination model.

Maternity Program: Alabama contracts with 10 primary contractors specifically for pregnancy-related care. Providers delivering maternity services should confirm their regional contractor relationships in addition to standard Medicaid enrollment.

ACHN Regional Structure

The ACHN is organized through regional entities covering specific geographic areas of Alabama. The regional entity a provider works with depends on the location of their practice. The full ACHN Interactive Map — showing which regional entity covers each county — is published at medicaid.alabama.gov/content/5.0_Managed_Care/5.1_ACHN/5.1.3_ACHN_Providers.aspx.

Each regional ACHN entity operates somewhat independently — with its own contact information, enrollment processes, and supplemental program guidelines. Providers with multiple locations in different regions may need to execute ACHN agreements with more than one regional entity.

Part 2: Alabama Medicaid 2026 Fee Schedule and Rate Updates

How Alabama Medicaid Sets Rates

Alabama Medicaid updates its fee schedules annually effective October 1 (the start of the state’s fiscal year) with quarterly adjustments at January 1, April 1, and July 1 for new codes or rate changes. The current FY2026 rates are in effect from October 1, 2025 through September 30, 2026.

Key 2026 Rate Updates

ACHN Enhanced Office Visit Rates: The 2026 rate for CPT 99213 (established patient office visit) is $78.19 for ACHN providers. This enhanced rate became effective October 1, 2025 for the current fiscal year. Non-ACHN enrolled providers receive the standard, lower FFS rate for the same code — making ACHN participation financially significant for primary care practices with substantial Medicaid patient volumes.

EPSDT Well-Child Screening Rate — $80.00: Alabama Medicaid raised the EPSDT (Early Periodic Screening, Diagnostic, and Treatment) screening rate to $80.00 per visit for codes 99381–99395. This rate took effect July 1, 2025 and continues through FY2026.

⚠️ Critical modifier requirement: Modifier EP must be appended to EPSDT screening claims. Without Modifier EP, the $80.00 screening rate will not apply and the claim will process at the standard preventive visit rate. Train your billing team — this modifier is mandatory for every EPSDT claim.

ACHN Quarterly Bonus Payments: ACHN providers qualify for quarterly bonus payments based on cost-effectiveness and quality metrics. Bonus payment cycles are quarterly, with funds distributed via the second checkwrite of each quarter. The January 2026 ACHN quarterly bonus was distributed on the second checkwrite of January 2026.

All PCP groups, including Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs), who actively participate with the ACHN may qualify to receive these bonus payments — making ACHN enrollment valuable not just for enhanced rates but for the performance-based revenue stream.

Perinatal Mood Disorder Screening — New January 1, 2026: Effective January 1, 2026, Alabama Medicaid reimburses perinatal mood disorder screenings for pregnant recipients over age 21. This expands maternal mental health care statewide and creates a new billable service category for OB/GYN practices, FQHCs, and primary care providers managing pregnant Medicaid patients.

Pharmacy Dispensing Fee: The pharmacy dispensing fee is $10.64 per prescription under the Alabama Community Pharmacy Relief Act. Under this state mandate, PBMs must reimburse independent pharmacies at this state-mandated Medicaid rate.

Nursing Facility Rates: Alabama Medicaid updated nursing home reimbursement for 2026, including therapy add-ons and new bed value calculations. The state will reconcile actual costs in April 2027 based on June 30, 2026 cost reports.

Alabama Medicaid Payment Schedule

Alabama Medicaid releases payments twice per month — not monthly like many other states. Funds typically reach provider bank accounts on the second Monday after the checkwrite date. Mark these checkwrite dates in your billing calendar — consistent payment cycle awareness is essential for cash flow management in practices with high Medicaid volume.

Part 3: Eligibility Verification in Alabama

Alabama Medicaid Interactive Web Portal

The primary eligibility verification tool for Alabama Medicaid providers is the Alabama Medicaid Interactive Web Portal at medicaid.alabama.gov. Providers can verify recipient eligibility, check benefit status, and confirm ACHN attribution (which PCP the patient is assigned to) through this portal.

Gainwell Fiscal Agent Helpline: 1-800-688-7989 — for claims and billing questions Provider Enrollment: (470) 657-9770 — contact Provider Enrollment Supervisor directly for enrollment questions

ALL Kids (CHIP) Eligibility

ALL Kids eligibility is verified separately from standard Medicaid eligibility. Since ALL Kids operates as a commercial-style insurance product, it has its own member ID system and verification process. Confirm ALL Kids enrollment and coverage details directly — do not assume standard Medicaid eligibility confirms ALL Kids coverage.

Key Eligibility Verification Rules for Alabama

Verify at every visit: Even in Alabama’s FFS model without MCO routing complexity, Medicaid eligibility can change. Verify through the portal before every encounter — not just at initial enrollment.

Check ACHN attribution: For ACHN providers, verifying which PCP the patient is attributed to is important for care coordination documentation and bonus payment calculations. The portal provides attribution status alongside eligibility.

Retroactive eligibility: Alabama Medicaid may grant retroactive eligibility for recipients who were eligible at the time of service but had not yet been formally enrolled. Verify retroactive eligibility before writing off claims for uninsured patients who later enroll — services rendered during the retroactive period may be billable.

---

Part 4: Claim Filing Limits in Alabama

Alabama Medicaid sets a clear and generous timely filing deadline, but commercial payers vary significantly.

⚠️ Important: Timely filing limits in your specific provider contracts govern your actual filing deadline. Always verify in your signed agreement with each payer.

Alabama Medicaid Timely Filing

Payer	Timely Filing Limit	Notes
Alabama Medicaid FFS (Gainwell)	12 months from date of service	One of the more generous state Medicaid filing windows — applies to all Alabama Medicaid FFS claims
ALL Kids (CHIP)	12 months from date of service	Verify with ALL Kids billing guidelines — may differ from FFS

Commercial and Medicare Timely Filing in Alabama

Payer	Timely Filing Limit	Notes
Medicare Part A and Part B	12 months from date of service	Palmetto GBA (MAC Jurisdiction J) processes Alabama Medicare claims
Medicare Advantage plans	90–120 days from date of service	MA plans set their own deadlines — significantly shorter than original Medicare
Blue Cross Blue Shield of Alabama	180 days from date of service	Dominant commercial carrier — verify by plan type
Viva Health (UnitedHealthcare subsidiary)	90–180 days from date of service	Verify with your specific contract
UnitedHealthcare (commercial)	90–180 days from date of service	Varies by employer contract
Aetna (commercial)	120 days from date of service	Verify with your contract
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 prompt submission

Part 5: 2026 Updates Every Alabama Provider Needs to Know

1. Email Contact Information Now Required for All Providers

Effective July 1, 2025, initial enrollment applications and revalidation documentation must include email address information for the following provider contact information fields: service location, pay to, mail to, patient contact/directory, and similar fields.

Alabama Medicaid now requires all providers to supply email address information for all provider contact information fields. If your provider enrollment record does not include current email addresses for all required contact fields, update through the Interactive Web Portal immediately. Missing email contact information can delay enrollment applications, revalidation approvals, and communication from the state about billing updates and provider alerts.

2. License Renewal Process Update — Electronic Verification

Most providers licensed in Alabama do not need to upload license renewals to Alabama Medicaid. These updates are sent electronically by your licensing board.

Only specific provider types are required to upload license renewals manually through the portal. All other providers have their licensing status updated electronically. However, DEA licenses require manual upload — prescribers of controlled substances are mandated to re-register their DEA License every three years. Upload a copy of the DEA Registration Certificate to the Medicaid Interactive Web Portal or fax to (334) 215-7416 with the barcode cover sheet from the portal.

3. New ACHN Enrollment Agreement Cycle — October 2024 Through September 2029

The current ACHN PCP Group Enrollment Agreement cycle runs October 2024 through September 2029. New providers joining the ACHN network must use the current agreement forms — previous cycle forms are no longer valid.

The required documents for this cycle are:

• PCP Group Application Checklist (5/22/24 version)
• PCP Group Enrollment Agreement with Medicaid
• PCP Group Enrollment Agreement Upload Process

These are available at the ACHN Providers page at medicaid.alabama.gov.

4. Perinatal Mood Disorder Screening — January 1, 2026

Starting January 1, 2026, Alabama Medicaid reimburses perinatal mood disorder screenings for pregnant recipients over age 21. This is a new reimbursable service category. Practices providing prenatal care to Alabama Medicaid patients should confirm their billing workflows capture this new screening service with the appropriate CPT or HCPCS code and the supporting ICD-10 diagnosis code.

5. ACHN Specialist Provider Enrollment Requirements

Incorrect provider specialties in the Medicaid enrollment file may cause delays in provision of ACHN care coordination services for Medicaid recipients. It is important that all participating ACHN providers — both group and individual — maintain their provider enrollment files with the Fiscal Agent, including accurate specialty designations.

If your specialty is listed incorrectly in the Medicaid system — which can happen when a provider joins a new group or when specialty training is updated — update it through the Interactive Web Portal immediately. An incorrect specialty can cause attribution errors in the ACHN system that affect both care coordination and bonus payment calculations.

6. After-Hours Requirements for ACHN Providers

ACHN participation requires that PCP groups provide recipients with after-hours instructions for care or referral at all times, 24 hours per day, 7 days per week. This is a compliance requirement of the ACHN enrollment agreement, not merely a recommendation. Documentation that after-hours coverage is available must be maintained — it is reviewed during ACHN audits and revalidation.

Part 6: Commercial Payer Landscape in Alabama

Alabama’s commercial insurance market is dominated by a single, deeply entrenched regional carrier and supplemented by national plans with significant market presence.

Blue Cross and Blue Shield of Alabama — The Dominant Carrier

Blue Cross and Blue Shield of Alabama (BCBS AL) is the dominant commercial insurer in the state by a substantial margin. With deep roots in Alabama’s healthcare market and longstanding employer relationships across all major industries, BCBS AL holds a larger share of the commercial insurance market in Alabama than most state-level Blue plans do elsewhere.

BCBS AL also operates Cahaba Government Benefit Administrators — the Medicare Administrative Contractor (MAC) subsidiary that historically processed Medicare claims in Alabama and surrounding states. While MAC contracting has evolved since 2005, BCBS AL’s relationship with CMS and familiarity with Alabama’s payer landscape makes it uniquely well-positioned in the state.

Any Alabama practice must prioritize BCBS AL credentialing above all other commercial carriers. If you are not in-network with BCBS AL in Alabama, you are out-of-network for the largest commercial insurer in the state.

Other Major Commercial Payers in Alabama

• Viva Health — a regional health plan that operates as a UnitedHealthcare subsidiary. Viva Health has strong market presence particularly in the Birmingham metropolitan area and is one of the primary commercial alternatives to BCBS AL in central Alabama. Viva Health offers HMO products and participates in Alabama’s ALL Kids CHIP program.
• UnitedHealthcare — significant employer-sponsored plan presence statewide, including both commercial and Medicare Advantage products
• Aetna — commercial presence particularly among large employer groups
• Cigna — commercial presence primarily in metropolitan areas — Birmingham, Huntsville, Mobile, Montgomery
• Humana — strong Medicare Advantage presence, reflecting Alabama’s significant senior population particularly in rural and suburban markets

Regional market notes:

• Birmingham (Jefferson County) — BCBS AL and Viva Health dominate; UnitedHealthcare significant for large employer groups
• Huntsville (Madison County) — BCBS AL dominant; UnitedHealthcare strong due to large defense and technology employer base
• Mobile (Mobile County) — BCBS AL dominant; Aetna present for coastal employer groups
• Montgomery (Montgomery County) — BCBS AL dominant; state employee health plans significant due to state government employment concentration
• Rural Alabama — BCBS AL coverage extends throughout rural markets; Medicare Advantage (Humana, UnitedHealthcare) significant for aging rural populations

ALL Kids — Alabama’s CHIP Program

ALL Kids is Alabama’s Children’s Health Insurance Program for children in families with income above the Medicaid threshold. ALL Kids operates through BCBS AL as the plan administrator — which means providers credentialed with BCBS AL are generally accessible to ALL Kids members. Confirm ALL Kids-specific billing requirements with BCBS AL provider relations when enrolling.

Part 7: Medicare in Alabama — Palmetto GBA

Alabama’s Medicare Administrative Contractor

Alabama’s Medicare claims are processed by Palmetto GBA, the Medicare Administrative Contractor for MAC Jurisdiction J. Palmetto GBA covers Alabama, Georgia, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia for Medicare Part A and Part B.

Palmetto GBA provider resources: palmettogba.com Jurisdiction J helpline: Confirm current numbers at palmettogba.com/palmetto/providers.nsf/contactus

Medicare Advantage in Alabama

Major Medicare Advantage plans operating in Alabama include:

• BCBS Alabama Medicare Advantage (BlueMedicare) — strong market presence given BCBS AL’s commercial dominance
• Humana Medicare Advantage — one of the strongest MA presences in Alabama, particularly in suburban and rural markets
• UnitedHealthcare Medicare Advantage — significant MA market share statewide
• Aetna Medicare Advantage — growing presence

For Alabama practices with significant Medicare Advantage volume, credentialing with each MA plan separately is required — MA plan credentialing is independent of original Medicare PECOS enrollment.

---

Part 8: Credentialing in Alabama — Two-Tier Enrollment

Step 1 — Alabama Medicaid Provider Enrollment (Gainwell Interactive Web Portal)

All providers who want to bill Alabama Medicaid must first enroll through the Gainwell Interactive Web Portal at medicaid.alabama.gov.

Requirements for enrollment:

• Active NPI (National Provider Identifier)
• Valid Alabama state license from the appropriate licensing board
• Current DEA registration (for applicable provider types) — must be uploaded manually
• Malpractice insurance documentation
• Practice location and contact information — including email addresses for all contact fields (required as of July 1, 2025)

Processing time: Standard enrollment applications take 30 to 45 business days for a clean submission. Submit the finalized application and record the Application Tracking Number (ATN). Track status on the portal dashboard every 5–7 days. Respond to any Requests for Information (RFIs) within the state’s narrow response window — failure to respond promptly causes the application to be denied and requires full resubmission.

Step 2 — ACHN Participation Agreement (Separate from Medicaid Enrollment)

After Medicaid enrollment is confirmed, providers who want enhanced rates and ACHN bonus payments must execute a separate ACHN Participation Agreement with their regional ACHN entity.

This is a separate process from Medicaid enrollment — one does not automatically trigger the other. The ACHN agreement adds approximately 2 to 4 weeks to the total timeline on top of the 30–45 day Medicaid enrollment period.

To initiate ACHN enrollment:

1. Identify your regional ACHN entity using the ACHN Interactive Map at medicaid.alabama.gov
2. Contact the ACHN entity directly using the ACHN Contact Information published on the Medicaid website
3. Complete the current cycle enrollment agreement (October 2024 – September 2029 forms)
4. Execute agreements with any additional regional entities for practices with locations in multiple ACHN regions

Step 3 — Alabama State Licensing

All providers practicing in Alabama must hold a valid license from the appropriate Alabama licensing board:

• Physicians (MD): Alabama Board of Medical Examiners — albme.org
• Physicians (DO): Alabama Board of Medical Examiners — albme.org
• Nurse Practitioners: Alabama Board of Nursing — abn.alabama.gov
• Physician Assistants: Alabama Board of Medical Examiners
• All other licensed providers: Alabama Department of Public Health or relevant board — adph.org

Alabama physician licenses renew on a biennial (2-year) cycle. License expiration stalls enrollment and revalidation. Build renewal reminders at least 90 days before expiration.

Commercial Payer Credentialing in Alabama

For commercial payer credentialing — BCBS AL, Viva Health, UnitedHealthcare, Aetna, Cigna, Humana:

• CAQH ProView is required by all major Alabama commercial carriers — maintain a complete and current CAQH profile (re-attest every 120 days) before approaching any commercial payer credentialing
• BCBS AL is the highest priority — credential here first given market dominance
• Viva Health is the second priority for practices in Birmingham and central Alabama markets
• Medicare (PECOS) enrollment should be completed concurrently with commercial credentialing

Alabama Credentialing Timeline Expectations

Payer / Enrollment	Typical Timeline
Alabama Medicaid (Gainwell Portal)	30–45 business days
ACHN Participation Agreement	2–4 weeks (after Medicaid enrollment)
BCBS Alabama (commercial)	60–90 days
Viva Health (commercial)	60–90 days
UnitedHealthcare (commercial)	60–90 days
Aetna / Cigna / Humana	90–120 days
Medicare PECOS (Palmetto GBA)	60–90 days

For a new practice in Alabama requiring full network participation, begin all credentialing a minimum of 120 days before the intended first date of patient care — and closer to 150 days if the ACHN secondary agreement is also required.

---

What Alabama Providers Should Do Right Now

For Medicaid billing and ACHN participation:

• Confirm your provider enrollment file in the Gainwell Interactive Web Portal is complete and current — including email addresses for all required contact fields
• Verify your specialty designation is correctly listed in the Medicaid system — incorrect specialties cause ACHN attribution delays and affect bonus payment calculations
• Confirm your ACHN Participation Agreement is on the current cycle (October 2024 – September 2029) — prior cycle agreements are no longer valid
• For EPSDT well-child visit claims — confirm Modifier EP is on every claim. Without it, the $80.00 rate will not process
• For practices treating pregnant Medicaid patients — confirm billing workflows capture the new perinatal mood disorder screening reimbursement effective January 1, 2026
• Check whether your DEA registration is current and uploaded — prescribers must re-register every 3 years and upload to the portal

For commercial payer credentialing:

• Prioritize BCBS Alabama credentialing above all other commercial carriers — it covers the largest share of commercially insured patients in every Alabama market
• For Birmingham-area practices, Viva Health is the second priority
• Confirm your CAQH profile is complete and re-attested — all major Alabama commercial payers pull credentials through CAQH

For revenue cycle management:

• Mark Alabama Medicaid’s twice-monthly payment schedule on your billing calendar — payments arrive on the second Monday after the checkwrite date
• Build the 12-month Alabama Medicaid timely filing window into your AR aging workflow
• For Medicare Advantage patients — confirm credentialing with each MA plan separately; PECOS enrollment does not automatically enroll you with Humana or UnitedHealthcare MA plans

Final Thoughts

Alabama’s ACHN model is one of the most distinctive Medicaid structures in the country. Without the MCO routing complexity of states like Illinois, Texas, or Florida, the billing pathway is more straightforward in some ways — but the two-tier enrollment requirement, the performance-based bonus structure, the strict EPSDT modifier requirements, and the ACHN specialty accuracy rules create their own operational demands that catch unprepared practices off guard.

The 2026 updates — including the new email requirement, the perinatal mood disorder screening reimbursement, the EPSDT rate increase, and the current ACHN agreement cycle — all require active attention to ensure your billing workflows are current and your enrollment files are complete.

At ClaimsXperts, we work with Alabama providers on Medicaid FFS billing, ACHN enrollment coordination, BCBS Alabama credentialing, and full-cycle revenue cycle management tailored to Alabama’s unique payer environment.
