In the world of health insurance, every step in planning and maintaining coverage matters. One of the most important processes that agents and agencies must master is eligibility redetermination, especially when working with plans like Ambetter, offered through the Affordable Care Act (ACA) Marketplace. This procedure can be the difference between a client keeping their subsidy or unknowingly losing it.
Understanding redetermination not only improves the customer experience but also protects the agent’s portfolio and ensures ongoing commission income.
What is Redetermination?
Redetermination is the annual process in which the Marketplace reviews whether a member still qualifies for subsidies such as the Advance Premium Tax Credit (APTC) y Cost-Sharing Reductions (CSR). This review considers:
- Household income
- Family size
- State of residence
- Immigration and tax status
The process can be automatic (if no changes occurred and information is up-to-date) or active, where the member must submit new documents or update their information.
If redetermination is not completed correctly or on time, the member may lose their subsidies or even their health coverage altogether.

Why Is Redetermination Critical with Ambetter?
1. Because Subsidies Depend on It
Ambetter, as an ACA plan provider, calculates premiums and deductibles based on federal subsidies. Without redetermination, the client can lose their APTC, which means:
- Higher monthly premium
- Increased out-of-pocket costs
- Risk of the plan becoming unaffordable

2. Because There Are New Regulations
CMS (Centers for Medicare & Medicaid Services): has tightened eligibility and verification processes for 2025. According to the “Marketplace Integrity and Affordability Rule,” states and insurers like Ambetter must apply stricter controls and carry out more accurate redeterminations, with penalties for inconsistencies.
This means it’s more essential than ever that the client’s information is correct and up-to-date.

How Does the Process Work with Ambetter?
Ambetter notifies its members when it’s time to complete redetermination. The notice may arrive via:
- Postal mail
- Envía un correo a
- Text message
- Portal notification
Ways to complete redetermination:
- Online (via Ambetter’s portal or HealthCare.gov)
- By phone, assisted by an agent or representative
- By mail, sending signed forms and documents
Once the information is submitted, the system reviews the data and issues a decision:
- If eligible, the subsidy continues.
- If ineligible, the subsidy is removed and the client must pay the full premium.
- If there are errors or missing data, a suspension or additional request may be issued.

What Happens If Redetermination Isn’t Done?
The consequences are serious:
- Loss of subsidies: The client will have to pay 100% of the premium.
- Plan cancellation: If the new amount is unaffordable, coverage is canceled.
- Loss of medical continuity: They may lose access to doctors, treatments, and medications.
- Financial impact on the agent: No active plan means no commission.

The Insurance Agent’s Role in the Process
Agents play a fundamental role in preventing clients from facing interruptions. Their duties include:
✅ Education and Reminders
- Sending notices ahead of the redetermination period
- Explaining what redetermination means and why it’s essential to act on time
✅ Personalized Support
- Helping the client gather documents
- Verifying that information is correct
- Assisting with submitting the data into the system
✅ Follow-Up
- Confirming that the subsidy was approved
- Helping resolve discrepancies
- Activating a Special Enrollment Period (SEP) if needed
Real-Life Cases That Show Its Importance
Case 1: Failed Redetermination Due to Address Change
A family moved and didn’t update their address. The redetermination notice never arrived, they didn’t respond in time, and lost their subsidy. They went three months without coverage before re-enrolling.
Lesson for agents: Always confirm and update contact information with each client, especially before OEP.
Case 2: Unreported Income
A client got a new job but didn’t report the income increase. During redetermination, the system flagged the discrepancy and blocked the APTC. The client had to repay the subsidy difference retroactively.
Lesson for agents: Reinforce the importance of reporting all income changes, even temporary ones.

Redetermination is a mandatory process—but it’s also a strategic opportunity to strengthen client relationships, ensure continuity of coverage, and protect your income structure. With Ambetter, this process becomes even more relevant due to the nature of ACA subsidies.
A well-informed and proactive agent can make all the difference between a well-covered client and one who loses everything due to a simple administrative oversight.
