CMS published preliminary Contract Year 2027 Part D bid data on July 28, 2026, showing a national average monthly bid of $296.05 and a base beneficiary premium of $41.33. At the same time, the Part D Premium Stabilization Demonstration ends December 31, 2026, and the standalone PDP market has shrunk to 360 plans. Agents should audit their book, wait for ANOC letters, and prepare plain-language explanations.
What exactly changed with Part D for 2027?
Two things happened at once, and the second one matters more than the first.
On July 28, 2026, CMS released the preliminary Part D bid information for contract year 2027. The national average monthly bid amount came in at $296.05, and the base beneficiary premium is $41.33. CMS also set the de minimis amount at $2, ran the rebate reallocation window from July 28 through August 6, and opened the de minimis participation election window from August 7 through August 11.
Those are the plumbing numbers. Carriers use them, actuaries use them, and honestly most of your clients will never hear the phrase “base beneficiary premium” in their lives.
Here’s the thing that actually reshapes your AEP conversations: the Part D Premium Stabilization Demonstration wraps up after the 2026 plan year. It ends December 31, 2026, and CMS has indicated it won’t be extended.
Why is the standalone PDP market shrinking?
Because the program that was propping up standalone PDP premiums is going away, and the market is repricing to actual bid math.
The demonstration was created to counterbalance the cost-sharing changes that came out of the Inflation Reduction Act. It smoothed the transition and kept standalone Prescription Drug Plan premiums artificially low while the new benefit design settled in. It worked as a bridge. But a bridge is a temporary structure by design.
For 2027, standalone PDPs return to normal market conditions. Premiums get set by what the bids actually say, not by a demonstration cushion. And carriers have been voting with their feet for a couple of years now.
Look at the plan counts:
- 2024: 709 standalone PDP plans nationally
- 2027: 360 standalone PDP plans
That’s roughly half the market gone in three years. Fewer choices, higher average premiums, and more member disruption when a plan a client has held for years simply isn’t offered anymore.
You’ve probably seen this coming if you’ve been watching plan finder counts shrink each fall. It just accelerated.
What does this mean for my Medigap-plus-PDP clients?
They’re the group most likely to feel it, and they’re often the clients you talk to least during AEP.
Think about who buys a standalone PDP. It’s usually someone on Original Medicare with a Medicare Supplement policy who purchases drug coverage separately. Those clients tend to be low-maintenance. Their Medigap plan doesn’t change much year to year, so you check in, confirm nothing’s broken, and move on.
This year that check-in needs to be a real conversation. If their PDP premium moves meaningfully, or their plan isn’t offered in 2027 at all, they’ll have questions — and they’ll call you first.
Some standalone PDPs may terminate outright. When that happens, the member gets an Annual Notice of Change letter with plan-exit notice, and there are Special Enrollment Period and Guaranteed Issue considerations attached to it. Know how those work before the phone rings, not during the call.
Some of those clients may end up looking at MA-PD plans — Medicare Advantage with drug coverage built in. That can be a legitimate fit for some people. It can also be a bad fit for someone who chose Medigap deliberately for provider freedom and predictable out-of-pocket costs.
The rule here is simple: a premium number is not a needs analysis. If a client moves, it should be because the full picture supports it, not because one line item went up.
How should I handle PDP conversations during AEP 2027?
Lead with process, not product. And follow the same compliance rules you’d follow for any Medicare Advantage conversation, because they apply here too.
CMS Third-Party Marketing Organization (TPMO) rules cover Part D conversations. You need a Scope of Appointment on file before you discuss specific plan details. You can’t steer a client toward a particular carrier, and you can’t make plan comparisons in a way that misrepresents options.
Practically, that means your PDP conversation this fall sounds like:
- “The market changed for 2027 — here’s why, in plain English.”
- “Let’s look at your actual drug list and your actual pharmacy.”
- “Here’s what your options are, and here’s how we compare them.”
Not: “Your premium went up, so let’s switch you to X.”
One more framing note, mostly for agents talking to other agents. A market disruption is not a commission event. If someone’s pitching this to you as a windfall, that’s the wrong lens — and depending on how it’s said, it’s compliance-adjacent territory. The right lens is that clients are going to need help, and prepared agents are the ones who can give it.
What should I do before ANOC letters land?
Get your house in order in August and September so October is calm.
Part D readiness checklist for AEP 2027:
- Audit your book. Filter by PDP carrier and separate standalone PDP clients from MA-PD clients. You want two clean lists. If your CRM can’t do that in about five minutes, that’s its own problem — this is exactly what a free Medicare CRM built for Medicare workflows should handle.
- Flag your Medigap-plus-PDP segment. These are the clients most exposed to standalone PDP changes. Sort them by how many prescriptions they take.
- Read ANOC letters, don’t just forward them. They start hitting mailboxes in late September and early October. Actually reading them is what separates you from an agent who sends a “did you get this?” text.
- Write your plain-language explanation now. Beneficiaries hear “premium up” and, if you can’t explain the market context, some of them will quietly blame you. Two or three sentences about the demonstration ending and the market repricing goes a long way.
- Refresh your Extra Help / LIS knowledge. Low-Income Subsidy clients are affected differently than full-premium clients. Make sure you know the difference before you’re explaining it live.
- Check formularies, not just premiums. A formulary change on a client’s maintenance drug will matter far more to them than a few dollars of premium. Pull drug lists for your highest-utilization clients.
- Update your compliance workflow for October 1. The CMS marketing rule changes take effect then — the 48-hour SOA hold is gone and TPMO disclaimer timing shifts. Make sure your scripts, forms, and automations reflect that.
- Don’t panic-message clients before ANOC letters arrive. Same rule as we covered with the Humana situation. Premature outreach creates confusion and compliance exposure.
How is this connected to the Humana MA exits?
It’s the other half of the same story.
Last week we covered Humana’s MA exits — this is the Part D side of the same 2027 disruption story. Medicare Advantage carriers are trimming plans for margin reasons. Standalone PDP carriers are exiting because a temporary premium cushion is going away. Different mechanics, same downstream effect: more beneficiaries getting letters that say their plan is changing or ending.
The Part D side has gotten a fraction of the coverage. That’s partly because standalone PDP doesn’t make headlines the way a big carrier’s earnings call does. But if you serve a lot of Medigap clients, this one may actually touch more of your book.
The good news is that the preparation overlaps almost completely. Clean book data, calm messaging, compliant process, and knowing what SEP and Guaranteed Issue rules apply. Do it once, and you’re ready for both.
How is this connected to the October 1 CMS marketing rule changes?
Directly, because more disruption means more enrollment conversations, and more conversations means more chances to get a compliance detail wrong.
The October 1 changes affect the mechanics of how you set up and document those conversations. With the 48-hour Scope of Appointment hold gone, you can move faster — which is genuinely helpful in a year with more plan movement. But faster also means the documentation habit has to be airtight, because you’re doing more of it under time pressure.
Same with the TPMO disclaimer timing shift. Update your scripts, your recorded call intros, and your CRM templates before AEP starts. Doing it in mid-October while your calendar is full is how mistakes happen.
What role should my FMO play in a Part D shakeup?
A useful FMO gets ahead of this instead of forwarding you a carrier email in November.
What that looks like in practice: clear explanations of what changed and why, updated compliance guidance before October 1 rather than after, help pulling and segmenting your book, and someone who picks up the phone when you hit a situation you haven’t seen before.
En TMS Correduría de Seguros (Texas Medicare Solutions), a Texas-based FMO with statewide reach, moments like this are where we spend most of our energy — training sessions on what actually changed, coaching on how to have the conversation without steering, and breakdowns on the Medicare Agent IQ podcast for the agents who’d rather listen than read. That’s the core of our training philosophy: give you the context and the systems, then let you run your own business. We work with agents across Texas and beyond, from busy metro books to rural ones where a single PDP exit can affect a whole county.
If you’re finding out about changes like this from a blog post instead of from your upline, that’s worth noticing. We’ve written before about how to switch FMOs safely if you decide the fit isn’t right.
The calm version of all this
The shift is real. Fewer standalone PDP options, premiums returning to market levels, and some clients getting letters they won’t understand.
None of that is a crisis for an agent who did the prep work. Audit the book, learn the why, wait for the ANOC letters, keep the process compliant, and have a real conversation instead of a reactive one. That’s the whole play.
If you want to talk through how you’d structure your Part D outreach this fall — or just want a second set of eyes on your book segmentation — we’re happy to walk through it with you. No pitch required.
