Getting started
Turning 65 in Greenville, TX
Turning 65 starts a clock, whether you grew up in Greenville or settled in Royse City or Caddo Mills a few years ago. Your Medicare sign-up window is seven months long. It opens three months before the month you turn 65, includes that month, and runs three months past it.
Get your application in early, during those first three months, and Medicare kicks in on the first of your birthday month. Wait longer and you'll start later. Most people do best by starting to plan at about 64 and a half.
- A seven-month sign-up window around your birthday
- Separate rules if you still have a job
- A single six-month Medigap window with no health questions
- Free, no-pressure help from our team

Check your employer coverage first
Still working, or covered by a spouse's employer plan? If that employer has 20 or more employees, you can usually delay Part B without a penalty. Under 20 employees, Medicare typically pays first at 65, and waiting can leave you underinsured. An HSA contribution changes the math again. Check with HR before you decide, or ask a licensed agent to walk through it with you.
Next step:
This is an estimate based on standard Medicare rules and your date of birth. It is not an official determination. Confirm your dates with Social Security or Medicare.gov.
Timeline
What to do, month by month
-
1
Three to six months ahead
Decide whether Part B starts now or waits because a current job covers you. Begin listing your doctors and medications.
-
2
Three months ahead
If enrollment isn't automatic for you, apply for Part A and Part B through Social Security. If you already get benefits, your card comes on its own.
-
3
Two months ahead
Pick a route: Original Medicare with Medigap and Part D, or a Medicare Advantage plan. See which plans include your Greenville doctors and any specialists you see in Rockwall, Garland or Dallas.
-
4
One month ahead
Submit your applications so the cards arrive in time. Make sure your current coverage doesn't stop before Medicare starts.
-
5
After your birthday
Once Part B starts, your six-month Medigap window opens. During it, your health can't change your price or whether an insurer accepts you.
Still working?
Coverage from a Dallas-area employer changes the timing
Maybe you still make the I-30 commute to a job in Dallas, Garland or Rockwall. Does your employer plan, or your spouse's, cover 20 or more workers? Then you can usually keep that plan and delay Part B with no penalty. Part A costs most people nothing, so they take it anyway. HSA savers are the exception. Once any part of Medicare starts, you can't add money to an HSA.
Leaving the job starts an eight-month window to sign up for Part B. Neither COBRA nor retiree coverage buys you extra time, whatever the HR packet seems to say. Missing it is one of the costliest Medicare mistakes there is. Run your own numbers in our Part B penalty calculator.
Working for a company under 20 people?
Then Medicare normally pays first once you turn 65. If you skip Part B, the job plan may refuse bills it expected Medicare to cover. Talk to your benefits office first.
Choosing
The two routes
- Original Medicare plus Medigap and Part D: almost every doctor who takes Medicare, more per month, very few surprise bills
- Medicare Advantage: less per month, a set network, copays at each visit, and dental and vision on many plans
- Whichever you pick, the monthly Part B premium still applies
- Ask a licensed agent to price each route, at no cost to you
Our pages on Medigap, Medicare Advantage and Part D drug plans go into more detail, and the Medicare checklist is a good first step. If your first window slips by, Annual Open Enrollment still lets you make changes from October 15 to December 7 each year.
