Many Medicare Advantage commercials mention a 'benefits card' you can use to buy things at Walmart or CVS, but rarely explain where that money comes from, what you can actually buy, or what happens if you do not use it. This guide explains precisely how the OTC (over-the-counter) benefit and the flex card that many Medicare Advantage plans offer actually work, so you can evaluate it clearly when comparing plans instead of relying only on what an ad says.
What the OTC benefit and flex card are
The over-the-counter (OTC) benefit is an add-on benefit that some Medicare Advantage plans offer, in addition to the medical and prescription drug coverage Medicare requires. It gives you a set amount of money, loaded onto a prepaid card, to buy approved over-the-counter products without using your own money. The 'flex card' is the name many insurers give to that same physical card, and on some plans - especially dual-eligible special needs plans (D-SNPs) - the same card may also include an additional amount for healthy food or help with certain household utility bills.
This benefit is not part of Original Medicare and is not required on every Medicare Advantage plan; it is an extra that each insurer chooses to offer or not, and it can change from year to year even within the same plan.
Availability, cost, benefits, and eligibility vary by person, product, contract, and insurance company, as well as by your service area. Guarantees are subject to the claims-paying ability of the issuing insurance company. Karla Arámburo is not affiliated with or endorsed by Medicare or the federal government.
What you can buy with the OTC balance
The exact list of eligible products is defined by each plan, but it generally includes items such as pain relievers, vitamins and supplements, bandages and first-aid supplies, allergy and cold medication, denture care, skin care products, thermometers, and on some plans, incontinence or diabetes management supplies that do not require a prescription. The card works like a prepaid debit card within the plan's store network: it is automatically declined if you try to use it on an item that is not on the approved list, such as food, clothing, or electronics, unless your specific plan includes those benefits separately.
How to activate the card
The card typically arrives by mail shortly after your plan enrollment takes effect, along with instructions to activate it, either by calling the customer service number on the back, through the benefit provider's mobile app, or by logging into your insurer's member portal. Until you activate it, the card has no available balance to use, so it is worth activating it as soon as you receive it rather than setting it aside for later.
Monthly vs. quarterly balance: why the difference matters
| Loading structure | What it means in practice |
|---|---|
| Monthly loading | You receive a portion of the annual benefit each month; if you do not use it that month, on many plans it is forfeited and does not roll into the next month. |
| Quarterly loading | You receive the balance every three months, giving more room to build up toward a larger purchase, but unused balance at the end of the quarter is generally also forfeited. |
Neither structure is automatically better; it depends on your shopping habits. If you prefer small, frequent purchases, a monthly balance may fit better. If you prefer to save up the benefit to buy several items at once, a quarterly balance gives more flexibility, as long as you remember to use it before it expires.
What happens if you do not use the balance
On the large majority of plans, unused OTC/flex balance within the assigned period (monthly, quarterly, or the full calendar year, depending on your specific plan's design) simply expires at the end of that period; it does not automatically carry over to the next one and does not convert to cash under any circumstance. Some plans do allow balance to accumulate within the same plan year, but this varies and should be confirmed by reviewing your specific plan's Evidence of Coverage (EOC), since it is not a uniform rule across insurers.
How to choose a plan with a good OTC benefit, without losing sight of the essentials
The OTC benefit can be a genuinely useful extra, but it should never be the main reason to choose a Medicare Advantage plan. Before being swayed by an attractive flex card amount, first compare whether your hospital and doctors are in the plan's network, whether your prescription drugs are well covered on the formulary, and what the plan's maximum out-of-pocket cost is for the year. Once those three things line up, the OTC benefit can be a good tiebreaker between two similar plans.

Many of my clients across Southern California, including families in San Diego and Riverside, ask me directly how much a plan's flex card carries before even knowing whether their doctor is in the network. I am glad to review both, in the right order, with you.

Frequently asked questions
Is the OTC/flex card the same on every Medicare Advantage plan?
No. Not every Medicare Advantage plan includes this benefit, and among those that do, the amount, loading frequency, and list of allowed items vary from plan to plan and from year to year. Always check your specific plan's Evidence of Coverage (EOC) rather than assuming it works the same as a family member's plan.
Can I use the OTC balance at any store?
Generally not. Each plan works with a specific network of participating pharmacies and stores (for example, certain pharmacy chains or the plan's own mail-order catalog), and the card usually declines purchases outside that network or of non-eligible items. The list of approved stores and products comes with the card or is available in the member portal.
Does unused balance turn into cash?
No. The OTC/flex benefit can only be used to purchase items or services approved by the plan; you cannot withdraw it as cash or transfer it to another account. If you do not use it within the period your plan assigns, it is generally forfeited.
Is a flex card the same thing as an OTC card?
Sometimes yes, sometimes no. Some plans use the same physical card for the OTC benefit and for other add-on benefits, such as healthy food or utility assistance (the latter is more common on special needs plans, or D-SNPs). Other plans issue separate cards for each benefit. Check your plan's materials to know exactly what your card covers.
What happens to the balance if I switch Medicare Advantage plans?
The balance belongs to the plan, not to you personally, so if you switch plans during the Annual Enrollment Period (AEP) or any other period, the balance does not follow you to the new plan and generally cannot be transferred. It is worth using the current plan's remaining balance before your coverage with that insurer ends.
How do I know how much balance I have left?
Most plans let you check the balance by calling the number on the back of the card, through the benefit's mobile app, or by logging into your plan's member portal. Many also send a receipt or message after each purchase showing the remaining balance.
Can you help me compare the OTC benefit across plans available in my ZIP code?
Yes. I review the amount, frequency, and store network of the OTC/flex benefit for plans available in your area with you, along with your doctor network and the real cost of your medications, so the decision does not rest on that extra benefit alone, at no cost to you.
