ANOC Season: How Insurance Agencies Defend Their Book When Carriers Mail Annual Notices

David Castillo
Operations Manager

Every September, carriers send beneficiaries a thick envelope titled "Annual Notice of Change." It is delivered by federal mandate, it lands while your agency is busy preparing for AEP, and it is the single biggest unmanaged threat to your renewal book. Most agencies treat ANOC like background radiation. Top-quartile agencies treat it like a campaign — six weeks long, scripted, measured, and run as outbound. The difference between those two postures shows up in your January persistency report and your CTM ratio.

What ANOC Actually Is, and Why It Hits Your Book

The ANOC is the federally required communication that tells a Medicare Advantage or Part D enrollee what is changing about their plan for the upcoming plan year — premium movement, MOOP changes, formulary changes, network changes, and benefit modifications. Under 42 CFR 422.111, plans must deliver the ANOC by September 30. The Evidence of Coverage usually arrives in the same envelope or shortly after.

From a member's perspective, the document is intimidating, dense, and arrives unprompted. The natural reaction is one of three: ignore it, start shopping, or call someone. Your agency's retention rate is determined by how often that "call someone" instinct lands on a phone number that belongs to your agency rather than a competitor's lead-vendor ad.

Why "Wait for Inbound" Is the Wrong Default

Most agencies under 50 producers run ANOC season as inbound-only. The agency answers when members call, and members are presumed to know their producer's number. This default loses three categories of members every year: members who lost the original producer's contact info, members who shop online and never call you, and members whose plan is changing in a way they do not understand and assume nobody can help them. The first two are obvious. The third is where the silent disenrollments come from.

The renewal you didn't get a chance to defend

If a member's PCP is dropping the network in 2027 and your agency does not call them in October, they will either (a) disenroll on their own through Medicare.gov or (b) get sold by whichever lead vendor's ad they clicked. Either outcome shows up as a loss in your January persistency report — and you never even had a conversation.

The Six-Week ANOC Outbound Cadence

Build the campaign as six discrete weeks, each with a specific message and disposition tree:

ANOC outbound campaign (Sept 1 - Oct 14)

1
Week 1 (Sept 1-7) — pre-ANOC heads-up: "Your carrier is going to mail you a notice in the next few weeks. Here's what it is. We will call you again to walk through it after it arrives."
2
Weeks 2-3 (Sept 8-21) — segmented outreach: prioritize members on plans with the largest 2027 changes (premium, formulary, network). Skip the bottom-quartile (no material change).
3
Weeks 4-5 (Sept 22 - Oct 5) — at-risk member calls: members whose ANOC includes a primary-care-physician network change, a major formulary tier change, or a $20+ premium increase get an explicit conversation.
4
Week 6 (Oct 6-14) — pre-AEP plan-review booking: by this week, every retained member should have a scheduled plan review either confirmed (no action needed) or booked into AEP.

Segmenting the Book Before You Dial

You will not get to every member in six weeks. You should not try. Segment by 2027 plan change severity, not by tenure or premium tier. The members who are silently churning are the ones whose plan is changing most — even if their carrier has the best Star rating in your stack. We covered the broader shopping behavior in our AEP/OEP/SEP overview; the ANOC-specific point is that material changes generate disenrollment intent, and your call is the intervention.

ANOC severity tiers

Tier Trigger Outreach priority
Red PCP/specialist network exit, formulary tier-3 drug movement 2 contact attempts in first 2 weeks; supervisor escalation
Yellow Premium increase $15+, OOP increase, ancillary benefit cut Outbound + SMS reminder if no answer
Green Largely unchanged plan, comparable network Light-touch SMS or postcard; no proactive call required

Compliance Considerations During ANOC Season

ANOC outreach to existing clients is a permitted activity outside the AEP marketing window — but it is still subject to TPMO and call-recording rules, and the call must be a service/retention call, not a sales call. The line between "I'm calling about your ANOC" and "I'm calling to switch you to a different plan" matters. If your retention call ends in a plan change discussion, the agent must follow CMS marketing rules including the TPMO disclaimer and any required SOA. This is exactly the use case driving our coverage of the CMS recording requirements; the calls are recorded, scored, and pulled in audits.

Scripts That Convert Members Into Bookings, Not Disenrollments

Most retention scripts fail because they sound transactional. The script that works opens with the member's specific 2027 plan change, names it before the member has to ask, and offers a scheduled plan review during AEP. The retention conversation is not the closing conversation — the closing conversation is the AEP appointment. Two-call structure: first call books the appointment; second call is the AEP plan review with full disclosures and SOA.

What an effective ANOC retention call covers

  • Identify yourself and the agency — recording-disclosure, agent-of-record acknowledgment.
  • Walk through the specific changes on the member's plan in plain language.
  • Surface the at-risk inputs — primary-care, prescriptions, total expected out-of-pocket.
  • Book the AEP plan review — exact date and time on the member's calendar.
  • Close with the do-nothing reminder — most members do not need a change; that itself is a retention message.

Measuring Whether ANOC Outbound Worked

Three measurements decide whether ANOC outbound paid back: the percentage of red-tier members successfully reached, the AEP plan-review booking rate against red and yellow tiers, and the January persistency on the contacted-vs-uncontacted cohort. The third number is the only one that proves the program. If contacted members renew at 92% and uncontacted members renew at 81%, that 11-point lift is the dollar value of the campaign. We get into the broader retention metric set in the Medicare retention playbook; ANOC outbound is the largest single intervention inside that playbook.

Key Takeaways for Agency Operators

  • ANOC is mailed under 42 CFR 422.111 — it lands by Sept 30 and triggers shopping intent.
  • "Wait for inbound" loses the silent disenrollers who never had your number handy.
  • Run a six-week outbound cadence — pre-ANOC heads-up, segmented outreach, at-risk calls, AEP booking.
  • Segment by plan-change severity, not by tenure or premium.
  • Two-call structure — retention call books the AEP plan review; AEP plan review is where you re-quote.
  • Measure contacted-vs-uncontacted persistency in January to prove campaign ROI.

Persistency is not a feeling; it is a controlled outbound campaign run inside a six-week window. ANOC season is the test. Agencies that turn it into a workflow keep their book; agencies that wait for the phone to ring lose 8-15 points of retention every year and never see the call that should have happened.

Run ANOC Outreach as a Workflow, Not a Hope
