Medicare OEP 2027: What Agents Can (and Can't) Do

Medicare’s Open Enrollment Period runs January 1 through March 31, and during it, CMS bans agents from doing the one thing agents normally do to win business: reach out. 42 CFR 422.2263(b)(7) prohibits knowingly targeting or sending unsolicited marketing to a Medicare Advantage enrollee during OEP. You can’t call them. You can’t mail them anything that mentions the OEP. You can’t buy a list of people who just picked a plan during AEP and try to win them back. The only door that’s open is the one the beneficiary opens themselves, by calling you, walking into your office, or asking for information directly. Everything in this piece is about what happens on the other side of that door, and what it costs an agency that isn’t standing there when it opens.

This is the compliance skeleton, the plain-English version of what’s allowed and what isn’t, the arithmetic on what an unanswered OEP call actually costs, a full method for building compliant coverage yourself, and where a system built to answer every call live changes the outcome instead of just the paperwork.

What Medicare’s Open Enrollment Period Actually Is

The Medicare Advantage Open Enrollment Period is a narrow, one-time window, January 1 through March 31, that lets someone already enrolled in an MA plan make a single change for the year. Per 42 CFR 422.62(a)(3), an individual enrolled in an MA plan may make one election during the first three months of the calendar year to enroll in a different MA plan, or to disenroll and return to Original Medicare. If they drop MA to go back to Original Medicare during OEP, they can also add a standalone Part D prescription drug plan at the same time, since dropping MA coverage would otherwise leave a gap. The regulation is explicit that this is a once-per-window election: use it, and that’s your one shot for the year, outside of a handful of exceptions like a Special Enrollment Period triggered by moving or losing other coverage.

That’s a fundamentally different animal from the Annual Enrollment Period, October 15 through December 7, which is fixed by the neighboring paragraph of the same regulation and is when nearly all Medicare Advantage plan shopping and switching actually happens. AEP is open season: any Medicare-eligible person can join, drop, or switch a plan, and agents can market to the entire eligible population the normal way, ads, calls, mailers, events, all of it governed by the standard Medicare Communications and Marketing Guidelines. OEP only opens for people who are already in an MA plan and want to undo or adjust that choice, and CMS built the marketing rules around it specifically so it can’t be worked like a second AEP.

Scale matters here, because OEP isn’t a niche event. KFF’s June 2026 enrollment brief, updated July 1, 2026 with March 2026 data, puts total Medicare Advantage enrollment at 35.2 million people, 55% of the 64.2 million Medicare beneficiaries who have both Part A and Part B. That’s a lot of current MA enrollees who are, by definition, eligible to use their one OEP change if something about their plan bothers them enough in January, February, or March, a premium increase they notice on the first bill of the year, a doctor who dropped out of network, a formulary change that hit a prescription. KFF also notes enrollment growth slowed to 3% between 2025 and 2026, down from 4% the year before, which matters for a different reason: a maturing market means more of your book is renewal business you already have, and OEP is disproportionately about keeping or losing people you already won, not net-new acquisition.

What CMS Actually Prohibits, and What’s Still Allowed

The rule that governs everything in this piece is 42 CFR 422.2263(b)(7): plans, and agents acting on their behalf, may not knowingly target or send unsolicited marketing materials to any MA enrollee during OEP. The regulation gets specific about what that means in practice, and it’s worth reading the actual list rather than the summary, because the boundary lines matter.

Read plainly, the line CMS drew is initiation. Who started the conversation. A beneficiary who picks up the phone and calls your office in February because their new plan’s pharmacy network doesn’t include their regular drugstore is doing something the regulation fully permits you to respond to. An agent who pulls a list of everyone who just enrolled during AEP and starts dialing in January, hoping some of them are having second thoughts, is doing exactly what 42 CFR 422.2263(b)(7) exists to stop. The two calls can sound almost identical once they’re happening. The only thing that separates a compliant OEP conversation from a violation is who picked up the phone first, which means your entire OEP compliance posture rests on being able to prove, cleanly, that every call in your system this quarter was inbound and beneficiary-initiated.

That’s also why the TPMO disclaimer requirement doesn’t take a break during OEP. 42 CFR 422.2267(e)(41)(ii) requires the disclaimer be conveyed verbally on sales calls before any benefits get discussed, and that rule applies to a beneficiary-initiated OEP call exactly the way it applies to an AEP call you made yourself. The channel that starts the conversation changed; what has to happen once someone’s on the line didn’t.

Why a Missed Call in OEP Isn’t a Delay, It’s the Whole Thing

Outside of OEP, missing an inbound call is a problem you can usually work around. You call the person back an hour later, or the next morning, and you’ve lost some momentum but not the opportunity. During AEP, if a lead goes cold, you can generate another one, run another ad, buy another list, dial again. Speed matters, but the door stays open because outbound marketing is legal the whole time.

OEP removes that safety net entirely. Once a beneficiary hangs up after your line rang out unanswered, you cannot legally call them back to pick the conversation back up, not tomorrow, not next week, unless they call you again first. 42 CFR 422.2263(b)(7) doesn’t carve out an exception for “they called us first, so a follow-up call from us is fine.” The initiation has to be theirs, every time, for the whole 90-day window. A missed OEP call isn’t a delayed conversation. It’s a permanently closed one, at least through the channel that would have been easiest for both sides.

That reframes what an unanswered line actually means during these three months. Invoca’s 2026 Lead Conversion Benchmarks Report, built from an analysis of more than 70 million calls and 600 million minutes of conversation data across ten industries including insurance, found that 56% of callers to businesses actually reach a person, which read the other way means 44% of inbound calls don’t connect to anyone at all. Outside OEP, that 44% is a follow-up list. Inside OEP, unless the caller tries again on their own, it’s gone.

What Missing That Call Actually Costs

Two separate costs stack up here: the cost of a call that never gets answered at all, and the cost of staffing a phone well enough that it usually does.

On the first, Invoca’s benchmark figure, 56% of business calls reaching a live person, isn’t insurance-specific in isolation, but it’s drawn from a dataset that explicitly includes insurance among its ten covered industries, and it’s the most current sourced figure available on general business call answer rates. We did not locate a second independently published dataset using a comparable methodology to corroborate that exact percentage, so treat it as a strong current benchmark rather than a universal constant, and check your own agency’s actual answer rate against your call tracking platform or CRM rather than assuming it matches.

On the second, staffing a phone with a person costs what a person costs, and that cost doesn’t shrink just because the busy season is three months instead of nine weeks. The Bureau of Labor Statistics’ Occupational Outlook Handbook puts the median annual wage for a receptionist at $37,230, or $17.90 an hour, as of its May 2024 data. That’s one person, covering standard business hours, for a full year. OEP calls don’t confine themselves to business hours any more than AEP calls do; a retiree with a Saturday morning free or a working adult calling about a parent’s coverage after dinner is a completely normal OEP caller, and a single receptionist working a 9-to-5 covers neither.

Run the two together and the shape of the problem gets clearer. A book of 35.2 million potential MA switchers nationally, per KFF, means your own book’s share of that population is going to generate some real number of OEP-season inbound calls if you carry any meaningful volume of Medicare Advantage clients, and each one of those calls is a beneficiary who, by definition, already has a plan and is deciding in real time whether to keep it, switch it, or leave you for someone else who answered. You can’t buy your way to a second chance at any of them once the call goes unanswered. The only lever left is answering the first time.

How to Build Compliant OEP Coverage Yourself

None of this requires buying anything. Here’s the actual method, the same one an agency with a spreadsheet, a shared inbox, and some discipline can run.

1. Route every OEP-season inbound call through one system you can audit. Whether that’s a single tracking number, a shared line, or your existing CRM’s call log, the point is that every call this quarter needs a timestamp and a record of who called in, so you can prove, if it ever comes up, that the contact was inbound and beneficiary-initiated, not something your team dialed out.

2. Cover the hours a retiree actually calls, not just your office hours. Look at when your OEP calls land, if you have historical data, or estimate conservatively: weekday evenings after 5pm, and weekend mornings, are realistic windows for a population that’s often retired or caring for someone who is. Staff those hours with a rotating on-call person, a live answering service, or forward the line to a cell phone that someone actually checks.

3. Script the disclaimer so nobody skips it under pressure. Write out the TPMO disclaimer verbatim per 42 CFR 422.2267(e)(41), post it somewhere every person answering the phone can see it mid-call, and make delivering it before any benefit discussion a non-negotiable first step in the call flow, not something that happens “usually.”

4. Build a hard stop against outbound follow-up on OEP contacts. This is the step agencies miss. A CRM workflow that automatically re-engages someone who called in but didn’t convert, “check back in a week,” a drip sequence, a reminder task to call them again, needs to be disabled or manually reviewed for every OEP-season contact specifically, because that kind of automated follow-up is exactly the unsolicited contact 42 CFR 422.2263(b)(7) prohibits, even when the CRM doesn’t know it’s breaking a rule.

5. Record and retain every call the same way you do the rest of the year. 42 CFR 422.2274(g)(2)(ii) requires 6 years of retention, audio for the first 3, regardless of season. Set it up once, in whatever recording tool you already use, and let it run.

6. Decide, in writing, what an answering person is allowed to say before an agent takes over. If you’re using a live answering service or a junior team member as the first point of contact, define exactly where their job ends, disclaimer delivery, basic identification, scheduling, and where a licensed agent has to take the call. Guessing on that boundary in the moment is how compliance gaps happen.

An agency that runs this by hand for a season, tracking calls in a spreadsheet, rotating who’s on call for evenings and weekends, checking the log weekly for anything that looks like it drifted into outbound territory, can do it. It’s real work for 90 days, and it competes with everything else an agency owner is already doing during a quarter that also includes tax season and, depending on the book, wrapping up whatever AEP left unfinished.

Where a Managed AI Answering System Changes the Math

This is the part TheAffordableAI actually does, described plainly and only in terms of what it does. It answers every inbound call, on the first ring, at any hour, so an OEP-season caller reaches a live conversation instead of a ring-out or a generic voicemail. It delivers the TPMO disclaimer verbally, before any benefit discussion, every single time, because the script doesn’t get tired or skip a step under call volume. It logs the call as what it is, inbound and beneficiary-initiated, with number warmup and spam defense running so your line doesn’t pick up a “Spam Likely” tag mid-season. And when the caller is ready, it does a warm transfer to a licensed agent, or books the appointment directly against real calendar availability through multi-calendar intent routing and HighLevel CRM sync, so the beneficiary lands with a human who can actually talk about their plan while they’re still on the line, not a callback promise for later.

That’s it. The licensed agent still handles the plan conversation, the recommendation, and the sale. The system doesn’t touch any of that, and using it doesn’t move compliance responsibility off the agent of record, the same as it wouldn’t if a human receptionist answered instead. Single Account runs $200 a month plus a $500 one-time setup, billed at $0.20 a minute down to $0.15 at bulk; Agency is $500 a month plus a $1,000 one-time setup, at $0.18 a minute down to $0.16 at bulk, and both come with no long-term contract, so trying it for one 90-day OEP season and stopping if it isn’t worth it is a real option, not a hypothetical one. Re-check current numbers on the pricing page before budgeting, since the live page is the source of truth.

What You Get When Coverage Doesn’t Take a Season Off

An agency that answers every OEP call live gets a few concrete things. It stops losing the members it already won during a previous AEP to whichever competitor happened to answer when that member decided to look around. It stops the awkward, compliance-risky improvisation of a busy staffer trying to remember mid-call whether this particular follow-up is allowed or not. And it gets a clean, auditable record that every OEP-season contact was exactly what the regulation requires it to be: inbound, unsolicited by the agency, and properly disclosed. None of that guarantees a close, and nothing here should be read as a promise that it will; what it changes is whether the beneficiary who called gets a real conversation instead of a dial tone.

The math above uses TheAffordableAI’s own numbers because that’s the product we build, but you don’t have to take the framing on faith. You can build the same coverage yourself with a rotating on-call schedule and a live answering service, and plenty of smaller agencies do exactly that. It’s worth pricing both against your actual OEP call volume before deciding either way, and no contract on either path means the risk of trying one for a season is capped at that season.
