Maximize Your Book of Business Before AEP Starts: Smart Strategies for Medicare Agents

The Annual Enrollment Period (AEP) is one of the most important — and busiest — times of the year for Medicare agents. But if you wait until October to get organized, you’re already behind. The most successful agents begin their marketing prep early. Why? Because reviewing your book of business ahead of time helps you keep more clients, reduce last-minute stress, and uncover new opportunities for growth.

AEP 2026 (October 15 – December 7) brings a new level of complexity. It’s not just the usual plan shuffles. There are real regulatory changes, rising client costs, and a shifting market landscape that every agent needs to understand now — not in October.

This article walks you through proven strategies to review, segment, and re-engage your book of business before the rush begins. We’ve also added the most important 2026 updates every agent needs to know.

What’s Different About AEP 2026?

Before we get into tactics, let’s look at what makes this year’s AEP unique.

Part B premiums hit a new milestone.

The standard Medicare Part B premium rose to $202.90 in 2026 — a nearly 10% jump from 2025 and the first time it has crossed the $200 mark. With Social Security cost-of-living increases projected at only around 2.6–2.7%, that Part B increase alone could eat up roughly 40% of the average beneficiary’s COLA raise. Your clients will feel this. Be ready to explain it.

The Part D out-of-pocket cap increased.

Starting in 2026, the annual cap on prescription drug out-of-pocket costs rose to $2,100, up from $2,000 in 2025. This is part of the broader Inflation Reduction Act changes reshaping how Part D works.

Medicare Advantage enrollment is declining for the first time in decades.

For the first time in over 20 years, MA enrollment is projected to decrease. Plan options have shrunk, non-commissionable plans have multiplied, and some carriers have exited the market entirely. There are 335 fewer non-special-needs MA plans available compared to last year. Clients who have stayed loyal to a plan may find it has changed or disappeared.

The Maximum Out-of-Pocket limit went up.

The national median MOOP for Medicare Advantage plans jumped from $5,400 in 2025 to $5,900 in 2026 — a nearly 10% increase. Clients attracted to $0 premium plans need to understand that higher costs could hit them hard if they actually use their benefits.

Special Needs Plans are growing fast.

While the broader MA market contracts, SNPs, including Dual-Eligible SNPs (D-SNPs) and Chronic Condition SNPs (C-SNPs), are expanding rapidly. If your clients qualify, this year may be the right time to take a closer look at SNP options.

New CMS marketing rules are in effect.

CMS has expanded its oversight of digital marketing. Every digital ad that mentions a specific plan, including paid search, social media posts, banner ads, and landing pages, must be filed through the Health Plan Management System (HPMS) before use. If you’re running digital campaigns, now is the time to make sure your materials are compliant.

Big change coming for the SOA process.

CMS finalized a rule eliminating the 48-hour waiting period between Scope of Appointment (SOA) completion and a personal marketing appointment. This takes effect October 1, 2026, for the 2027 contract year. The SOA is still required before any sales conversation — you just won’t have to wait 48 hours once you have it. Also eliminated: the 12-hour prohibition between educational and sales events at the same location, provided beneficiaries are notified and given a chance to leave before the marketing portion begins. SOA forms can now also be collected at educational events.

Mid-year benefit notifications are now required.

Starting in 2026, Medicare Advantage plans must send enrollees a personalized “Mid-Year Enrollee Notification of Unused Supplemental Benefits” between June 30 and July 31. This lists supplemental benefits each enrollee has not yet used in the first half of the year. This creates a natural opening to reconnect with clients before AEP even begins.

Step 1: Clean and Review Your Client List

Before you can serve your clients well, you need a clean and accurate list. Your book of business is one of your most valuable assets. Treat it that way.

Start by asking:

• Are client names, contact info, and plan details up to date?
• Are there any duplicates or outdated entries?
• Who has moved, passed away, or switched to another agent?
• Which clients are enrolled in plans that are being discontinued or significantly changed for 2026?
• Which clients are in Medicare Advantage plans with significantly higher MOOPs this year?

Tip: If you haven’t updated your client list since last AEP, do it now. Clean data means better outreach and fewer errors during crunch time. With fewer MA plans on the market and carriers making big changes, there’s more urgency than ever to know exactly what your clients are enrolled in — before they call you with problems.

Step 2: Segment Your Clients Strategically

Once your list is accurate, the next step is segmentation. This means dividing your clients into groups based on their needs, plan types, or risk level so you can personalize your outreach effectively.

Helpful ways to segment in 2026:

• By plan type: Medicare Advantage (MA), Medicare Supplement, or Prescription Drug Plans (PDP)
• By carrier: Especially important if your clients’ carriers are exiting markets or reducing plan offerings this year
• By MOOP exposure: Clients in high-MOOP plans who use significant medical services are at financial risk and need a proactive review
• By enrollment history: New clients vs. long-term clients
• By SNP eligibility: Dual-eligible or chronically ill clients who might benefit from switching to a D-SNP or C-SNP
• By Part D impact: Who has high prescription drug costs and could benefit from the new out-of-pocket cap structure?
• By retention risk: Who hasn’t been in contact in the last year? Who might be shopping around?

Segmenting helps you create a targeted plan of action and prevents you from sending generic messages that don’t apply to everyone.

Step 3: Identify Clients Who Need a Plan Review

Not every client needs to change their plan. But in 2026, more clients than usual may benefit from a review. Plan benefits, networks, and cost structures have shifted significantly across the industry.

Clients who are most likely to need a review:

• Those whose plans are being discontinued or significantly changed
• Clients in MA plans with higher MOOPs or reduced extra benefits (dental, vision, hearing)
• Anyone with new prescriptions or changing health needs
• Clients who have moved to a different ZIP code or state
• People who are turning 65 or nearing retirement
• Dual-eligible clients who may qualify for a D-SNP
• Anyone who expresses dissatisfaction with their current plan

Tip: Use the new mid-year benefit notification that MA plans are now required to send between June 30 and July 31 as a conversation starter. Reach out proactively and offer to walk clients through any unused benefits. This simple touchpoint builds trust and keeps you top of mind before AEP begins.

You can also send a simple survey or checklist to help clients self-identify if they might benefit from a review. This saves you time and helps prioritize your appointment schedule.

Step 4: Stay Ahead of Compliance Requirements

2026 brings important compliance updates every agent must follow.

TPMO Disclaimer: If you are considered a Third-Party Marketing Organization, you must include the required CMS disclaimer in all marketing materials — including digital ads, emails, and social media. The disclaimer reads: “We do not offer every plan available in your area. Please contact Medicare.gov or 1-800-MEDICARE to get information on all of your options.”

Digital marketing rules: Any online content that mentions a specific plan by name, highlights specific benefits, or includes enrollment information must be filed with CMS through HPMS before it’s published. This applies to paid search ads, social media posts, banner ads, landing pages, and email campaigns. Plan-specific web pages must include the required disclaimer, a multi-language insert, and a non-discrimination notice.

SOA requirements: The SOA must still be obtained before any sales conversation. The 48-hour waiting period is being eliminated effective October 1, 2026, for the 2027 contract year. SOA forms can now be collected at educational events. Review your process now so you’re ready when the new rules take effect.

Sales events vs. educational events: Any event where plan-specific benefits are discussed is a sales event, regardless of how it’s advertised. Make sure your event marketing reflects that. Food provided at educational events must remain nominal in value.

Annual certifications: Before you can sell during AEP 2026, you must complete your AHIP certification and product certifications for each carrier you’re appointed with. Many carriers offer AHIP discounts when you certify through their portal. Don’t wait on this.

Step 5: Use CRM Tools to Automate and Streamline Outreach

A Customer Relationship Management (CRM) system is a must-have for managing your book of business during AEP. If you’re not using one, now is the time to start.

CRM tools help you:

• Set up reminders and appointment scheduling
• Tag clients by plan type, carrier, MOOP level, or retention risk
• Track communication history for compliance purposes
• Send personalized emails, texts, or mailers in batches
• Automate follow-ups and confirmations

Bonus: Use Tools Like Hub to Streamline Your Process

LeadingResponse’s Hub is built specifically with Medicare agents in mind. It helps you manage your Medicare marketing campaigns, track leads from every event, and stay organized during the AEP rush. With Hub, you can:

• See RSVP status and engagement from seminar or webinar invites
• Access event performance data and attendee lists in one place
• Track every lead from first contact to follow-up

Step 6: Create an Outreach Calendar

You know who to contact. Now it’s time to plan when and how.

Build a simple outreach calendar that includes:

• June–July: Reach out about mid-year benefit notifications — help clients use benefits they’ve been missing
• August–September: Watch for carrier plan previews, track Star Rating updates, and prepare educational event materials
• Early October: Complete AHIP certification and carrier certifications if not already done
• October 15: AEP begins — all CMS-approved marketing materials should already be ready
• October 15 – December 7: Initial touchpoints (email, phone, mailers), high-priority client appointments, educational events, follow-up reminders
• Post-December 7: Follow up with any clients who didn’t make changes and remind them the Medicare Advantage Open Enrollment Period (MA OEP) runs January 1 – March 31

Having a calendar in place keeps you on track and helps you avoid the last-minute pile-up during the busiest weeks of the season.

Why This Year Matters More Than Most

Clients are going to feel the cost increases in 2026, with higher Part B premiums, higher MOOPs, higher deductibles, and reduced extra benefits in some MA plans. They need an agent who reached out early, knows their situation, and helps them understand their options before they make a panicked decision during AEP.

Agents who prepare now will have more time to:

• Focus on quality conversations, not just paperwork
• Retain more clients and increase renewal income
• Reduce last-minute changes and appointment overload
• Build trust and loyalty through proactive service

Remember, AEP is more than a race to sign people up. It’s your chance to show clients that you’re a trusted partner — every single year.

Final Thoughts

Medicare agents who plan ahead always have the upper hand. By taking the time now to clean up your book of business, understand the 2026 market changes, segment your clients, and set up your outreach calendar, you’ll walk into AEP confident rather than scrambling.

You don’t need a massive team or a fancy system to get results. You need a smart process and a head start. So don’t wait. Start maximizing your book of business today — and make this your most productive AEP season yet.
