Some time in the first week of October, your phone starts ringing, and the callers all open the same way: "I got a letter from my plan." The letter is the Annual Notice of Change, and by federal rule it has to reach every one of your continuing clients by September 30. Which means that for two weeks every fall, most of your book is holding a document about their 2027 coverage — and you are the only one of the two of you who can actually read it.

Most agents work ANOC season in the order the phone rings. The agents who finish AEP ahead work it the other way around: as a book-wide triage list built before the phone rings at all. This is how to build that list, what the ANOC tells you, and — more useful — what it doesn't.

What an ANOC Actually Is, and What It Isn't

The Annual Notice of Change is the standardized notice a Medicare Advantage or Part D plan must send each current enrollee describing what changes on January 1: premium, deductible, cost sharing, drug coverage, and provider network. The September 30 deadline isn't a custom — it's arithmetic. CMS's disclosure rules at 42 CFR 422.111(d)(2) require a plan to notify enrollees of changes taking effect January 1 at least 15 days before the Annual Coordinated Election Period begins. AEP opens October 15. Fifteen days earlier is September 30.

Here is the distinction that trips up clients and newer agents alike: an ANOC is a continuation document. It is what a plan sends when it intends to still be there next year. A member whose plan is terminating, or whose county is dropping out of the service area, gets something else — a non-renewal notice, which generally goes out in October, separately. An ANOC arriving is not bad news by itself. An ANOC not arriving can be, and it is the quietest signal in your book because nothing shows up to prompt the call.

The second thing worth knowing is what the letter leaves out. Since contract year 2019, the ANOC and the Evidence of Coverage have been separate documents on separate clocks. The ANOC is due by September 30; the EOC — the long document carrying the full benefit detail behind every line in it — isn't due until October 15, and under CMS's materials rules a plan may post it electronically and mail members a notice of how to access it. The letter your client is waving at you on October 2 is a summary of changes, not the contract those changes live in.

The Two Weeks When You Can Read but Not Sell

The ANOC deadline sits inside a marketing restriction, and that is deliberate. Under CMS's Medicare Communications and Marketing Guidelines, plans and the agents representing them may not market the coming plan year before October 1, and may not accept enrollments for it before October 15. Your clients learn what is changing before anyone is permitted to sell them the alternative.

So the stretch from September 30 to October 14 is a service window, not a sales window. It is time to read, sort, and answer questions about the notice a client received — not to pitch next year's replacement. Where exactly the line falls for a specific activity is a question for the current MCMG and your FMO's compliance desk, not for a blog post or an agent Facebook group. CMS republishes this guidance, the details move, and "someone told me it was fine last year" has never once worked as a defense.

Triage the Book by Impact, Not Alphabetically

Every ANOC is not a call. Sorting them into four buckets, in this order, is the whole exercise:

  • Tier 1 — no ANOC, or a non-renewal letter instead. The plan is going away, or the county is. These are the clients who will be shopped by somebody, and the only question is whether it's you. They also carry the longest runway: a non-renewal opens a Special Enrollment Period that runs past the close of AEP, which our read on the 2027 carrier exits covers in detail. Confirm the current window in CMS's enrollment guidance before you lean on it in a client conversation.
  • Tier 2 — formulary changes. A drug dropped from the list, moved to a higher tier, or newly subject to prior authorization is the most expensive thing a client can miss, because it doesn't surface in September. It surfaces in January, at the pharmacy counter, with a number nobody warned them about. Every client on a maintenance drug belongs in this tier until you've checked.
  • Tier 3 — network changes. The ANOC tells you the network changed. It does not tell you whether their cardiologist is still in it — that's a client-level question against a plan-level document, and it is the single most common reason a satisfied client becomes an unsatisfied one in February.
  • Tier 4 — cost drift, no structural change. Premium and copays moved, nothing broke. This is the "your plan still works, let's review anyway" call. It is also the one most agents skip, which is exactly why it is worth making.

That last tier is not charity. CMS caps renewal compensation at roughly half the initial rate — for 2027, $363 against $725 in most states, the figures we keep published on our compensation breakdown, and caps rather than guarantees. Renewals on kept clients are what compound into a business, and the cheapest retention call of the year is the one you make to somebody whose plan is fine.

Every client's Part D math moved this year, even if their plan didn't

A plan can change nothing and still cost your client more, because the benefit design underneath it moved. CMS set the 2027 Part D standard benefit parameters in April 2026: the standard deductible rises to $700, from $615 in 2026, and the annual out-of-pocket threshold — the point past which a member pays nothing more for covered drugs that year — rises to $2,400, from $2,100. The deductible figure is the standard-benefit maximum, and plans may charge less or none at all, so read what the ANOC says rather than assuming. But the direction is set centrally, it applies everywhere, and no carrier is going to explain it in the letter.

What to Read on the Letter, in Order

The ANOC is built as a side-by-side comparison — this year in one column, next year in the other — which makes it fast to work once you know where to look. Six lines carry most of the decisions:

  • Monthly premium, and whether a $0 plan stayed at $0.
  • Medical deductible and the maximum out-of-pocket. A rising MOOP is a risk transfer, and it is invisible to a client who has never had a bad year.
  • Primary, specialist, and emergency copays — the numbers a client actually experiences monthly.
  • Drug tiers, the Part D deductible, and which tiers it applies to. Two plans with identical premiums can be hundreds of dollars apart here.
  • Supplemental allowances — dental, vision, hearing, OTC and flex cards. Carriers under margin pressure have been trimming these first, and they are what a lot of members believe they bought.
  • The network statement, which tells you to go look rather than telling you the answer.

One thing the ANOC will not carry: the plan's star rating for the coming year. CMS posts the new ratings in early October, ahead of AEP, and they show up next to the plan on Medicare Plan Finder. A client whose plan quietly lost a star won't learn it from the mail.

Turning Reads Into a Call Order

The point of triage is a sequence, not a spreadsheet. Three moves make it real:

  • Record the tier, not the impression. One field in your CRM, filled in as you read. In late October you will not remember which of 300 clients had the formulary problem, and re-reading is not a plan.
  • Cross-reference on October 1. Plan-level data for the new year publishes then. That is the first day your Tier 1 list stops being an inference and becomes a list of names and counties.
  • Call in tier order, and keep the overflow. Tier 1 first, Tier 2 before AEP if you can reach them, Tiers 3 and 4 across the season. Anyone you can't close by December 7 who is disrupted doesn't disappear — they carry into the new year, with far fewer agents still working.

Speed matters more than polish in this stretch, and looking things up is most of the work. AskRamona, our AI assistant, is free to agents and open in English and Spanish — useful when you are working through twenty letters and want a plain-language answer without leaving the desk. Verify anything plan-specific against the plan's own documents before it reaches a client. That rule holds for every tool, ours included.

The Bottom Line

The ANOC is the earliest signal an agent gets, and it is almost always read too late — one letter at a time, after a client calls, in the middle of the busiest six weeks of the year. Read as a batch in the first days of October, the same letters sort your entire season: who is about to lose coverage, who is about to be surprised at the pharmacy, who needs a network check, and who just needs to hear from you.

Your clients will get their letters by September 30 whether you have a plan for them or not. The agent who read them first is the one who calls before the competitor does — and being the first call, every year, is most of what keeps a book.
