The Medicare Annual Enrollment Period 2026 opens on October 15. That’s six months away. For most Medicare Advantage plans, six months feels like enough time. It rarely is.
AEP preparation isn’t a Q3 project. It’s a Q2 project. Agent training takes weeks. Surge staffing takes longer. Quality frameworks need to be tested before they run under live AEP pressure. Plans that start preparing in August are already behind.
More importantly, the members who switch at AEP aren’t making their decisions in October. They’re forming their intentions in June, July, and August. Based on their experiences throughout the year, the prior authorization was denied, but no one explained why. Based on the benefit cut, nobody warned them about andon the complaint that was closed but never actually resolved.
This guide covers what drives AEP switching behavior in 2026, what the member experience standard looks like during the window itself, and what Medicare Advantage plans need to build before October 15.
What Makes AEP 2026 Different
Every AEP has a character. AEP 2026 is shaped by several converging pressures that make the member experience more decisive than in prior years.
AEP 2026 runs from October 15 to December 7, 2026, for 2027 coverage. Members switching during this window select a plan effective January 1, 2027. Plans that win AEP 2026 capture members for a full calendar year of premium revenue. Plans that lose members face both revenue loss and higher acquisition costs to replace them.
Several forces make this AEP unusually competitive:
- Benefit reductions created dissatisfied members. Several major plans cut supplemental benefits entering 2026. Those members arrive at AEP with a specific grievance. They’re actively looking for alternatives.
- The Part D cap created confusion. Members who don’t understand the $2,000 out-of-pocket cap feel unsupported by their plan. That feeling translates to switching intention.
- Stars’ pressure increased competition. Plans that lost Stars rating points are more motivated to compete aggressively for market share at AEP. Marketing will be loud in 2026.
- CMS marketing restrictions tightened. Third-party marketing organizations operate under stricter rules. Plans that built enrollment on aggressive TPO marketing face a channel constraint.
Against this backdrop, member experience — the quality of every interaction a member has with their plan throughout the year — is the primary retention variable. Plans with strong member experience programs arrive at AEP with a loyal base. Plans without them arrive exposed.
Why Member Experience Drives AEP Switching Behavior
Members don’t make AEP switching decisions rationally. They make them emotionally — based on how their plan made them feel throughout the year.
A member comparing Plan A and Plan B in October uses premiums and benefits as the basis for comparison. But their starting position — whether they’re inclined to stay or inclined to leave — is set months earlier. By how their medication confusion was handled in February. Whether the denial letter in May included a clear explanation. Whether anyone called to remind them about their dental benefit in September.
Key Insight
Members who receive proactive outreach from their plan at least twice during the year — a benefits call, an HEDIS reminder, or care gap outreach — disenroll at significantly lower rates than members with no proactive contact. The outreach creates a relationship. The relationship creates retention.
This is why the best AEP retention strategy isn’t a stronger save call in October. It’s a stronger member experience program in March, April, May, June, and July. The AEP call closes retention. Everything before it creates it.
The complete framework for year-round engagement is covered in our Medicare Advantage retention strategy guide. This article focuses specifically on what AEP itself demands from contact center operations.
What AEP Demands From Contact Center Operations
AEP is not a normal operating period for Medicare member services. It concentrates enrollment, comparison, and retention decisions into a 53-day window. Contact volume spikes by 3–5× compared to steady state. The interactions are higher stakes. And the consequences of poor service quality are immediately visible in enrollment data.
Here’s what AEP-ready contact center operations deliver:
Surge Capacity Without Quality Degradation
Most plans staff for steady-state volume. When AEP hits, they scramble. Hold times increase. First-contact resolution drops. Members who can’t reach their plan during AEP form a negative impression at exactly the moment they’re deciding whether to stay.
AEP-ready operations build surge capacity before October 15. They add trained agents specifically for the AEP window. They test call routing under load. And they define hold time thresholds that trigger escalation — rather than discovering hold time failures in post-AEP CAHPS data.
| AEP Contact Center Standard | Why It Matters | Preparation Requirement |
|---|---|---|
| Hold time <5 minutes | CMS monitors hold times; CAHPS reflects accessibility | Surge staffing plan finalized by August |
| First-contact resolution >80% | Callbacks during AEP frustrate members considering switching | Benefits knowledge refresher training before October |
| CMS-compliant benefit communication | Non-compliant AEP communications generate CMS audit risk | Script review and compliance training in September |
| Multilingual coverage for LEP members | LEP members who can’t access AEP support are most likely to disenroll | Language coverage audit and gap fill before October |
| 100% quality monitoring during AEP | AEP is when compliance and accuracy failures are most costly | AI QMS deployment or manual sampling uplift planned now |
AEP-Specific Agent Training
AEP agents face questions that general member services agents don’t encounter as often. Plan comparison questions. Formulary change explanations. Supplemental benefit value demonstrations. The $2,000 Part D cap mechanics. CMS marketing compliance requirements during enrollment conversations.
Generic member services training doesn’t adequately cover these topics. AEP-specific training must address:
- The plan’s 2027 benefit structure — what changed and why
- Formulary changes — which medications moved, which were added, or removed
- Part D $2,000 cap mechanics — how it works, how to explain it in plain language
- Network changes — which providers left, which joined, and how to assist members in finding alternatives
- CMS marketing compliance rules — what agents can and cannot say during AEP contacts
- Retention authority — what offers or commitments agents can make to at-risk members
This training should be completed by late September. Agents who go live on October 15 without AEP-specific preparation are a compliance and member experience risk.
Proactive Retention Outreach — Not Just Inbound Handling
The best AEP contact center operations don’t just answer calls. They make them. Proactive retention outreach targets at-risk members before they call competitors — based on complaint history, benefit utilization, demographic risk factors, and satisfaction signals.
The conversation is not a hard sell. It’s a service call. The agent reaches out to confirm the member has what they need for the new plan year. They address any unresolved concerns, explain benefit changes clearly, and confirm the member’s intent to renew or surface concerns while there’s still time to address them.
Retention Outreach Timing
Begin proactive AEP retention calls in mid-October — as soon as the window opens. Members who receive a retention call in week one of AEP convert at higher rates than those contacted in week six. Don’t wait until the deadline is close.
AEP 2026 opens in six months. Plans that start preparing in August are already behind.

What Members Experience During AEP — and What Shapes Their Decision
From the member’s perspective, AEP is confusing. Marketing materials arrive from multiple plans. Benefit comparison is difficult. The consequences of choosing wrong are significant — a medication formulary change, a network difference, or a premium that is higher than expected.
Members are currently turning to their current plan’s contact center. They call to confirm their benefits, ask whether their medications are still covered, and check whether their doctor stays in the network. How those calls go — how accessible the plan is, how accurately the agent answers, how confidently the agent explains the plan’s value — shapes the renewal decision more than any marketing material.
| Member AEP Question | What a Good Answer Delivers | What a Poor Answer Delivers |
|---|---|---|
| “Is my doctor still in network?” | Confirmed answer; alternative offered if not; member feels supported | Uncertain answer; hold to check; member doubts plan reliability |
| “Will my medication be covered in 2027?” | Accurate formulary answer; cost explained; member stays calm | Wrong answer discovered at the pharmacy in January; the member files a complaint |
| “Why did my dental benefit change?” | Clear explanation; full remaining benefit value outlined; member feels heard | Agent doesn’t know; escalation required; member loses confidence |
| “How does the $2,000 drug cap work?” | Clear, correct explanation; member appreciates the benefit; positive impression | Incorrect or confused answer; member doubts plan’s competence |
| “Should I switch to Plan X?” | CMS-compliant response; current plan value articulated; no steering | Non-compliant steering; CMS audit risk; member still switches |
The AEP 2026 Preparation Timeline
Here is the preparation sequence that gets plans to October 15 ready — not scrambling.
April – May 2026: Assess and Plan
- Review AEP 2025 performance data — hold times, FCR, member satisfaction, disenrollment rates by segment
- Identify at-risk member segments for targeted AEP retention outreach
- Audit multilingual coverage gaps — confirm native-language capacity for LEP populations in your service area
- Model surge volume — estimate AEP contact volume based on prior year plus market change factors
June – July 2026: Build
- Finalize surge staffing plan — identify internal vs. outsourced capacity split
- Begin pre-AEP member engagement — proactive outreach to members with benefit changes, complaint history, or low utilization
- Draft AEP-specific training curriculum — 2027 benefits, formulary changes, Part D cap, CMS compliance
- Confirm HEDIS care gap outreach completion before measurement windows close
August – September 2026: Train and Test
- Complete AEP agent training — all surge agents certified before October 1
- Conduct AEP load test — simulate peak call volume to identify routing and hold time failure points
- Review and approve AEP outbound call scripts for CMS compliance
- Finalize retention segmentation and outreach call list — prioritized by disenrollment risk
October 15 – December 7: Execute AEP
- Surge staffing active from day one — not week three
- Proactive retention outreach begins in week one — highest-risk segments first
- Daily monitoring of hold time, FCR, and quality metrics — with same-day escalation for threshold breaches
- 100% interaction monitoring active — AI QMS or equivalent for compliance and quality assurance
How AEP Performance Shapes Next Year’s CAHPS Scores
AEP member experience doesn’t just affect disenrollment rates. It affects Stars ratings — through CAHPS scores collected in the months following AEP.
Members who had a poor AEP experience — long holds, wrong information, unresolved concerns — report lower satisfaction on CAHPS surveys. Those surveys feed into the member experience Stars measures that determine quality bonus payments for 2028. The financial consequences of poor AEP execution echo for two full plan years.
Conversely, plans that deliver exceptional AEP service — accessible, accurate, empathetic, multilingual — convert the moment of highest member scrutiny into a positive experience. Those members report higher CAHPS scores. They renew. And they’re more likely to refer family members during AEP.
The connection between daily member services quality and CAHPS outcomes is covered in detail in our guide to healthcare CX trends for 2026. The pattern is consistent: investment in contact center quality during AEP produces Stars improvements that outlast the enrollment window itself.
