How does Counterclaim generate an insurance appeal letter?

Counterclaim uses a 5-agent AI pipeline. The Reader extracts claim data from your document. The Researcher identifies applicable state insurance law. The Writer drafts a formal appeal letter.

What types of insurance denials can Counterclaim handle?

Counterclaim handles all major denial types: medical necessity (CO-50), prior authorization (CO-11), experimental treatment (PR-1), fee schedule (CO-45), timely filing (PR-27), not covered (CO-4), step therapy (PR-50), and missing information (CO-16).

What file formats does Counterclaim accept?

Counterclaim accepts PDF files, JPG and PNG photos, and scanned documents of your denial letter or Explanation of Benefits (EOB).

Does Counterclaim provide legal advice?

No. Counterclaim generates appeal letters based on publicly available legal and clinical information but does not constitute legal advice. For complex cases, consult a licensed healthcare attorney or certified patient advocate.

Which Centene company do I appeal to?

It depends on your plan. Ambetter (ambetterhealth.com) for Marketplace coverage, Wellcare (wellcare.com) for Medicare Advantage, Fidelis Care (fideliscare.org) for New York, Health Net (healthnet.com) for California, and various state-branded Medicaid plans (Sunshine Health, Magnolia Health, Buckeye Health, Peach State Health, Superior HealthPlan, etc.). Use the appeals address on your denial notice or the back of your member ID card.

Can I get an expedited appeal with Centene?

Yes. Federal law (45 CFR section 147.136) and Medicare Advantage rules require 72-hour expedited decisions when delay would jeopardize the patient's life, health, or ability to regain function. Mark the appeal 'expedited' or 'urgent' and have your physician confirm clinical urgency.

What if my Centene Medicaid plan denied my appeal?

After Centene's internal appeal, you have the right to a state Medicaid fair hearing. File within the deadline on the denial (usually 90 to 120 days). Fair hearings are conducted by the state Medicaid agency, not the managed-care plan, and the hearing officer's decision is binding.

Does Counterclaim handle Ambetter appeals?

Yes - Ambetter is a Centene Marketplace product and follows ACA appeal rules. The Reader agent identifies Ambetter from the denial letterhead and the Writer drafts to the appropriate appeals unit and timelines.

Can I keep getting services while my Centene Medicaid appeal is pending?

In most states yes - this is called 'aid paid pending' or 'continuation of benefits.' If you file the appeal before the effective date of the action (or within 10 days of receiving the notice, whichever is later), you can request that services continue while the appeal is decided. If you ultimately lose the appeal, the state may seek to recover the cost of services provided during the appeal.

Which state-branded Medicaid plans are Centene subsidiaries?

A non-exhaustive list: Sunshine Health (Florida), Magnolia Health (Mississippi), Buckeye Health Plan (Ohio), Peach State Health Plan (Georgia), Superior HealthPlan (Texas), MHS (Indiana), Coordinated Care (Washington), Centene Pennsylvania (PA Health & Wellness), Western Sky Community Care (New Mexico), Bridgeway Health Solutions (Arizona), and many more. The denial letter will identify the correct subsidiary.

How do I appeal a Wellcare Part D drug denial?

Wellcare Part D follows the standard CMS Part D appeal procedure: file a coverage determination request with the plan first (using the model exception form), then redetermination if denied, then auto-forward to the Independent Review Entity at level 2. Include physician documentation of medical necessity, prior-failed-therapy history if you're requesting a tiering or formulary exception, and any contraindication documentation for step-therapy override.

What if my Centene Marketplace plan has changed networks mid-year?

Marketplace plans generally cannot drop in-network providers mid-year except for cause; if Ambetter denied a claim because a previously in-network provider was reclassified, contest the timing and demand continuity-of-care protections under the ACA and state Marketplace rules. Document when the provider was in-network at the time of service and any state notice requirements that Centene may not have met.

Centene Denial Appeal - Free AI Letter Generator | Counterclaim

Centene operates Ambetter (Marketplace), Wellcare (Medicare), Fidelis (NY), and Medicaid managed-care plans across most US states. Upload your denial and our 5-agent AI pipeline routes the appeal to the correct Centene subsidiary.

Centene Corporation is the largest Medicaid managed-care insurer in the US and operates a portfolio of state-branded subsidiaries plus several national brands. Centene's three largest product lines are: Medicaid managed care (operating in 30+ states under brands like Sunshine Health in Florida, Magnolia Health in Mississippi, Buckeye Health in Ohio, Peach State Health in Georgia, Superior HealthPlan in Texas, and many more); Ambetter, the company's ACA Marketplace brand operating in over 25 states; and Wellcare, the company's Medicare Advantage and Medicare Part D brand operating in 36+ states (Centene acquired Wellcare in 2020). Centene also operates Fidelis Care in New York (Medicaid, Marketplace, and Medicare), Health Net in California, and is the TRICARE West Region contractor for military families. The appeal procedure depends entirely on which Centene subsidiary issued the denial - Marketplace appeals follow ACA timelines, Wellcare Medicare follows CMS rules, and state Medicaid managed-care appeals follow each state Medicaid agency's procedures with the binding state-fair-hearing escalation. The Counterclaim pipeline reads the denial letterhead first to identify the specific Centene subsidiary, then applies the correct timeline, deadline, and escalation framework. Members should not assume that a denial on Centene corporate stationery applies the same procedure across product lines - Ambetter, Wellcare, and the state-branded Medicaid plans are operationally distinct even though they share corporate ownership.

How Centene's appeal process works

Centene appeals follow the rules of the specific subsidiary and product line: Ambetter Marketplace plans follow ACA appeal timelines (180 days to file internal, then external review); Wellcare Medicare follows CMS Medicare Advantage timelines; Centene's state Medicaid managed-care plans follow each state Medicaid agency's procedures including the right to a fair hearing. The denial letter identifies the correct routing.

Step 1: Identify the Centene subsidiary on the denial letterhead - Ambetter, Wellcare, Fidelis, Sunshine Health, Magnolia Health, Buckeye Health, Peach State Health, Superior HealthPlan, Health Net, etc. Step 2: Use the deadline that applies to that product line. Ambetter Marketplace: 180 days from denial. Wellcare Medicare Advantage: 60 days for reconsideration. State Medicaid: typically 60 days (varies by state). Step 3: File a written appeal to the address on your denial notice or member ID card. For Medicaid, this will be the state-branded subsidiary's appeals unit. Step 4: Include the denial notice, the member ID, the claim or authorization number, the clinical evidence, and a physician letter of medical necessity. Step 5: Mark the appeal expedited if delay would jeopardize health - 72-hour decision under federal rule for all product lines. Step 6: For state Medicaid managed-care members, after exhausting the plan's internal appeal, request a state Medicaid fair hearing within the deadline on the appeal denial (usually 90 to 120 days). Federal regulations at 42 CFR section 438.402 require MCO internal exhaustion before fair hearing in most states. Step 7: For Wellcare Medicare Advantage, the Level 2 reconsideration auto-forwards to MAXIMUS Federal Services as the IRE. Step 8: For Ambetter Marketplace, after internal exhaustion request external review through the state IRO process.

What makes Centene appeals succeed

Centene appeals succeed most often when they: (1) correctly identify the specific Centene subsidiary and the product line, since the appeal procedure differs sharply between Ambetter Marketplace, Wellcare Medicare, and the state-branded Medicaid plans, and a misrouted appeal can delay escalation by weeks; (2) for Medicaid managed-care appeals, preserve the state-fair-hearing escalation right by filing the internal appeal correctly and requesting continuation of benefits ('aid paid pending') if available; (3) for Wellcare MA SNF and post-acute denials, attach the SNF medical record and reference the OIG findings on MA post-acute denials and the Jimmo v. Sebelius improvement-not-required standard for skilled-care coverage; (4) for Ambetter denials on narrow-network plans, contest the network-adequacy basis of out-of-network denials when no in-network alternative is reasonably available within the ACA network-adequacy standard or the state Marketplace network rules; (5) cite the state Medicaid agency's fair-hearing right and federal 42 CFR Part 438 protections explicitly, particularly for non-emergency transportation, behavioral-health, and DME denials that are common Medicaid managed-care issues; (6) for pharmacy denials handled through Centene's PBM, request the formulary exception or step-therapy override using the model exception process and document prior-failed-therapy history; and (7) preserve a complete written record of timeliness by sending appeals via certified mail with return receipt, particularly for Medicaid appeals where a missed internal-appeal deadline forfeits the fair-hearing right.

Recent regulatory and public-record context

Centene paid a series of state Medicaid pharmacy-benefit settlements totaling over a billion dollars between 2021 and 2023, resolving allegations that its pharmacy benefit manager (Envolve / Centene's PBM) overcharged state Medicaid programs for prescription drugs. The settlements involved Ohio, Mississippi, Illinois, Arkansas, Kansas, New Mexico, Texas, Washington, and others. Centene also faced state insurance regulator scrutiny in several states over Marketplace network adequacy on narrow Ambetter plans. None of these settlements affects appeal procedure on a given denial, but they form public-record context.

Where to mail your Centene appeal

Centene does not publish a single national appeals address. Routing depends on your specific plan, product, or state. Use the address printed on your denial notice or on the back of your member ID card. The official appeals page is linked below.
