Medicare Open Enrollment with ChatGPT: Understand Your Plan Letter and Get Ready to Compare (Oct 15 to Dec 7)

Why this is worth 15 minutes

Medicare.gov says your costs, benefits and providers can change each year, and that comparing your options could help you find better coverage or save money. The hard part is the paperwork: a thick letter full of words like “formulary” and “tier,” and a pile of mail from companies selling plans. ChatGPT is good at exactly that kind of reading. You paste or photograph the pages (numbers covered) and it hands back a short list: what’s changing, what to check and what to ask.

The dates and rules (from Medicare.gov)

Checked Oct 26, 2026, on Medicare.gov and in Medicare’s “Your Yearly Medicare Review” booklet (September 2026 edition). Give these to ChatGPT so it plans around them instead of guessing.

• Open Enrollment: October 15 to December 7. Changes you make start January 1. A health or drug plan must get your enrollment request by December 7.
• What you can do: join, switch or drop a Medicare Advantage Plan or a Medicare drug plan, switch between Original Medicare and Medicare Advantage, or keep what you have.
• Happy with your plan? Medicare says you don’t need to do anything; your coverage continues automatically. Any changes your plan made for the new year still start January 1.
• Your plan’s “Annual Notice of Change” (ANOC): if you’re in a Medicare plan, your plan sends it each fall (Medicare lists September). It lists changes in coverage, costs and more that start in January. Didn’t get one? Medicare says to contact your plan.
• Have Medigap? Medicare’s booklet warns that if you drop Medigap to join a Medicare Advantage Plan, you may not be able to get the same Medigap policy back later. Ask before you drop it.
• Already in Medicare Advantage? There’s a second window, January 1 to March 31, to switch to a different Medicare Advantage Plan or go back to Original Medicare (with the option to join a separate drug plan).

Step 1: Gather your papers (5 minutes)

• Your plan’s Annual Notice of Change letter, if you’re in a Medicare Advantage or drug plan.
• Your pill bottles or a printed medication list: name, dose and how often.
• Your doctors and your pharmacy, by name and town.
• All your insurance cards. Before any photo or paste, cover your Medicare Number, Social Security Number and member ID with a sticky note.

3 copy-paste prompts to try today

1. 📬 Explain my plan’s Annual Notice of Change

I have Medicare. Here is my plan's "Annual Notice of
Change" letter for next year (my Medicare Number and
member ID are covered): [PASTE TEXT OR ATTACH PHOTOS]
1. In plain English, list what changes on January 1:
   premium, deductible, copays, drug coverage, doctors
   or pharmacies in the network, and any benefits added
   or dropped.
2. Put it in a table: Topic | This year | Next year |
   Page where it says this.
3. Flag anything that could affect me, given that I take
   [MEDICINES] and see [DOCTORS] at [PHARMACY / CLINIC].
4. Don't guess. If something isn't in the letter, write
   NOT IN LETTER, and list it as a question for my plan.
Use short sentences and big, simple words.

Check every number it lists against the letter itself. If the table says a page number, turn to that page.

2. 💊 Build my list for Medicare’s Plan Finder

Help me get ready to compare Medicare plans at
Medicare.gov/plan-compare. Here is my messy list:
- Medicines: [NAMES, DOSES, HOW OFTEN; OR "SEE PHOTO"]
- Doctors and specialists: [NAMES, TOWNS]
- Pharmacy: [NAME, TOWN; MAIL-ORDER YES/NO]
- Things that matter to me: [E.G. KEEP MY DOCTOR, LOW
  MONTHLY COST, DENTAL OR VISION, TRAVEL]
- I live part of the year in: [STATE, IF ANY]
1. Clean this into one neat list I can type into Plan
   Finder, one medicine per line with dose and how often.
2. Mark anything that looks unclear, like a missing dose,
   with [CHECK].
3. Turn "things that matter" into a short checklist I can
   tick off for each plan I look at.
Don't recommend a plan or guess prices.

Medicare.gov says to add all the prescription drugs you take regularly to get the most accurate monthly and yearly cost estimate for each plan, and to ask your doctors and pharmacies if they’re in the plan’s network.

3. 📞 My questions before I call for free help

I'm going to call [1-800-MEDICARE / MY STATE'S SHIP
COUNSELOR / MY PLAN] about Open Enrollment, which ends
December 7. My situation: [ORIGINAL MEDICARE / MEDICARE
ADVANTAGE / DRUG PLAN / MEDIGAP], and I'm worried about
[E.G. A DRUG COST GOING UP, MY DOCTOR LEAVING].
1. Write my 8 most important questions, most important
   first, in plain words.
2. Add a short "what to have in front of me" list.
3. Leave space under each question to write the answer,
   the person's first name and the date.
Don't answer the questions yourself; I'll get the
answers from the call.

Medicare’s booklet lists two free places to get help comparing plans: 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048, open 24 hours a day including weekends, and your State Health Insurance Assistance Program (SHIP) for free counseling (the booklet says to visit shiphelp.org for your local SHIP’s number). Medicare.gov says SHIPs aren’t connected to any insurance company or health plan.

Step 2: Compare on Medicare.gov, not in the chat

• Use Medicare.gov/plan-compare. Medicare’s booklet says you can compare plans side by side, get estimates of your total out-of-pocket costs, see quality and customer service ratings from current members, and search for your doctors to see if they’re in a plan’s network.
• Make sure a plan fits. Medicare.gov’s checklist: does it cover your prescriptions and the benefits you need, are your doctors and pharmacies in network, what are the premiums, deductibles and estimated yearly drug costs, and will it cover you if you live in another state part of the year.
• Have other coverage, like from a job or union? Medicare.gov says to talk to your benefits administrator or other insurer before you join a plan or change anything.
• Bring the results back to ChatGPT only to organize them. Paste your own notes and use members’ prompt #4 above to line them up; never ask it to “pick the best plan.”

Step 3: Join, switch or keep, by December 7

• Keeping your plan? You don’t need to do anything, Medicare says.
• Joining or switching? Medicare.gov lists 3 ways: select “Enroll” for the plan at Medicare.gov/plan-compare; contact the plan by phone, website or a paper form (which it must get before the period ends); or call 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048.
• Write it down. Keep the date, the plan name and any confirmation number with your Open Enrollment notes.

Scam check: “Medicare” calling?

Medicare.gov is clear about this, and it’s worth taping by the phone:

• Medicare will never call you to sell you anything or visit you at your home.
• Don’t join a Medicare health or drug plan over the phone unless you called and asked for help.
• Don’t give your Medicare card, Medicare Number, Social Security card or Social Security Number to anyone except your doctor or people you know should have it (like your SHIP counselor or insurers acting for you).
• Don’t accept money or gifts for “free” medical care.
• Think it’s fraud? Medicare.gov says to call 1-800-MEDICARE (1-800-633-4227) or report it online. In a Medicare Advantage or drug plan, you can also call the I-MEDIC line at 1-877-7SAFERX (1-877-772-3379).

Privacy tips

• Cover the numbers, every time. ChatGPT never needs your Medicare Number, Social Security Number, member ID or date of birth to explain a letter.
• Medicine names are enough. List the drug, dose and how often; skip diagnoses unless you want to include them.
• Don’t want it saved? Use a Temporary chat, or turn Memory off; see Is my AI assistant safe? for the settings.

Troubleshooting

• It told me which plan to pick. Say: “Don’t recommend a plan. Only organize what’s in my notes and list questions.” Then compare at Medicare.gov/plan-compare.
• Its dates don’t match this page. Paste the Medicare.gov dates above and say: “Use these.” Medicare.gov has the final say.
• The photo of my letter is hard for it to read. Take one page at a time in good light, flat on a table, or type the key lines in.
• It feels like too much. Do just prompt #1 today. Knowing what’s changing is half the job.
