If you sell Part D or Medicare Advantage prescription drug plans, you’re about to field a lot of premium questions this AEP. CMS has confirmed that the Part D Premium Stabilization Demonstration, the temporary program that has helped keep standalone drug plan premiums predictable since 2025, will end on December 31, 2026. Starting in 2027, insurers will price their Part D plans without that federal support.
For the roughly 25 million beneficiaries enrolled in standalone Part D plans, this is a real change worth getting ahead of. Here’s what’s happening and how to talk your clients through it with confidence.
What’s Actually Changing
The Premium Stabilization Demonstration was built as a bridge, not a permanent fixture. It launched in 2024 to help insurers adjust to the Inflation Reduction Act’s redesigned Part D benefit, including the new out-of-pocket cap. The program worked by lowering the base premium used in pricing calculations and capping how much year-over-year premiums could increase.
CMS has said insurers have had enough time to adjust and no longer need that support. Once the program winds down, plan sponsors will set 2027 premiums under standard market conditions.
What It Means for Premiums
Estimates on the size of the impact vary depending on the source. CMS has projected that most beneficiaries will see increases of less than $10 a month, with some plans holding steady or even decreasing. Other health policy analysts, including those at KFF, have estimated the change could mean increases of up to $20 a month for some beneficiaries, since the subsidy has been offsetting a meaningful share of the average standalone plan premium.
The honest answer for your clients right now is that the exact numbers won’t be clear until plan sponsors release 2027 premiums and clients receive their Annual Notice of Change this fall. What you can tell them with confidence is what isn’t changing.
What Isn’t Changing
This is an important distinction to lead with, because “Part D subsidy ending” headlines can sound scarier than the reality. As AARP notes, the broader IRA-driven improvements to Part D remain fully in place:
- The annual out-of-pocket cap continues its scheduled increase to $2,400 in 2027
- Lower insulin costs stay in effect
- Free recommended vaccines continue
- The redesigned Part D benefit structure is unaffected
Framing the conversation this way, real premium movement paired with real protections still standing, helps clients hear the full picture instead of just the headline.
How to Support Your Clients This AEP
- Get ahead of the question. Don’t wait for clients to bring this up after seeing a news headline. A short, proactive outreach before their Annual Notice of Change arrives builds trust and positions you as the source they turn to first.
- Wait for the real numbers before quoting anything. Until CMS and plan sponsors finalize 2027 pricing, avoid giving clients specific dollar estimates. Point them to the range of expert projections and let them know you’ll follow up with exact figures as soon as plans are published.
- Review every standalone Part D client’s plan fit. A premium shift is a natural moment to confirm the client is still in the right plan, not just the same plan out of habit. This is a good year to run a full comparison during AEP rather than a quick renewal check.
- Keep the conversation compliant. As always, any discussion of premium changes should stick to CMS-approved language and avoid speculation presented as fact. Stay within your TPMO disclaimers and documented scope of appointment when these conversations turn into enrollment discussions.
- Lean on your FMO. This is exactly the kind of shifting landscape where having a team behind you matters. Carolina Senior Marketing is tracking these updates closely and will get final 2027 pricing details and talking points into your hands as soon as they’re available.
The Bottom Line
The Part D subsidy ending doesn’t mean Part D is ending, and it doesn’t undo the protections seniors have gained since 2025. It does mean premium conversations deserve extra attention this AEP. Agents who get ahead of the story, stay factual, and lean on their FMO for support will be the ones their clients trust most when the real numbers land this fall.
