Quick Read
Walmart's 2027 health plans include more than 250 medications, such as GLP-1 drugs and insulin, at no cost for eligible employees, but not for retirees on Medicare.
An inhaler that costs $400 a month under Walmart's plan could still cost a retiree as much as $1,725 a year under Medicare Part D in 2027.
Retirees need to sign up for Medicare Part D within 63 days of losing Walmart coverage or risk a lifetime late enrollment penalty added to monthly premiums.
Employees who use low-cost generics may notice little change after moving to Medicare. Those who depend on expensive brand-name medicines, especially GLP-1 drugs and inhalers, could see a much larger jump in pharmacy costs.
Walmart's $0 Tier Applies Only While You're Employed
The zero-cost tier is available to eligible workers and dependents enrolled in qualifying Walmart medical plans. Walmart's enrollment period runs through Nov. 6. The company did not extend the benefit to former employees on Medicare.

Now Available: The 401k Answers Nobody Gives You.
For many Americans, saving in a 401(k) brings up more retirement questions. Should the money be rolled into an IRA, and if so, when? What happens tax-wise if the rollover check is made out incorrectly? When do required withdrawals start, and how much must be taken?
------
An associate who keeps working past age 65 may be able to remain on Walmart's medical coverage, including the $0 prescription tier. Once she retires, she must secure Medicare drug coverage if she no longer has other qualifying insurance. Going 63 straight days or more without Part D or other creditable prescription coverage can lead to a late enrollment penalty. Medicare adds 1% of the national base beneficiary premium for every full month without coverage, which can raise drug premiums for life.
Five Rules Shape a Retiree's Drug Costs
One Inhaler, Two Different Price Tags
Consider an inhaler with an estimated monthly cost of $400. If it qualifies for Walmart's $0 tier, the employee pays nothing while enrolled in the company's eligible medical plan. Under a 2027 Part D plan with a $700 deductible and 25% coinsurance, though, the retiree's annual out-of-pocket cost could climb to $1,725.
Coverage (2027, illustrative) | Monthly cost to patient | Annual cost to patient |
|---|---|---|
Walmart plan, $0 tier | $0 | $0 |
Part D plan, after deductible | $100 | $1,725 (includes the $700 deductible) |
The patient pays the full drug cost until reaching the $700 deductible, then pays 25% of the remaining covered spending. Over a full year, that adds up to $1,725 for the inhaler alone. If a covered brand-name GLP-1 is added, out-of-pocket costs could reach the $2,400 annual cap. A plan with no deductible or lower cost-sharing could be much cheaper. If the inhaler is not covered, however, the retiree could owe the full price unless the plan grants an exception. None of these outcomes automatically carry over from Walmart's drug list.
What to Review Before Coverage Changes Take Effect
Medicare's annual open enrollment ends Monday, December 7, and coverage changes begin January 1. Workers who retire later in the year may qualify for a separate enrollment window when employer coverage ends. In either case, comparing Medicare drug costs before leaving Walmart could help avoid an expensive surprise.
Walmart's new prescription benefit could save employees hundreds or even thousands of dollars each year. But those savings may not follow them into retirement. Reviewing Medicare coverage before leaving the job could mean the difference between paying nothing at the pharmacy and facing a much larger annual bill.
