Flex card transportation: when a Medicare Advantage card can pay for a ride, and what changes January 1, 2027

A flex card is a debit card that a Medicare Advantage plan gives members to pay for certain covered benefits, and it pays for a ride only when the rider’s plan covers rides on the card and your business is one the card accepts. When a card declines, the limit usually comes from how the plan set up the card, not from your card reader. This page covers how plans put ride benefits on cards, why a card declines at a ride company, what the new CMS rule changes on January 1, 2027, and what to hand a rider so the plan can pay them back. How plans arrange rides through transportation vendors is in Medicare Advantage transportation.

What is a flex card, and is it cash?

A flex card is not cash. CMS’s rule calls it a debit card, and it describes the card as a tool for administering plan-covered benefits rather than a benefit in itself. Federal law bars plans from giving enrollees cash, and in the April 2026 final rule CMS says plan cards are “not intended to be usable everywhere.” A card can only be used for items and services the plan covers, and the plan must list in its evidence of coverage which benefits the card reaches (42 CFR 422.111(b)(6)).

CMS says plans use these cards for reduced cost sharing on dental and vision, and to pay for over-the-counter items, fitness benefits, food and produce, transportation and utilities support. So a rider’s card may hold money for several things at once. The ride benefit may be one of them, or it may not be on the card at all.

Which plan benefits can put a ride on a card?

Two kinds of benefit can: a rides benefit for the plan’s members, and a non-medical rides benefit for chronically ill members. Both are explained in more detail in Medicare Advantage transportation. The card is only the payment tool for either one.

• Rides for health care. Some plans cover transportation as a supplemental benefit. CMS’s example is a plan that provides a transportation service as a covered benefit and gives members a debit card to reduce what they owe for those defined transportation services.
• Non-medical rides for chronically ill members. CMS’s 2019 guidance says transportation to get non-medical items and services, such as grocery shopping and banking, can be reimbursed, arranged or provided directly as a special supplemental benefit for the chronically ill (SSBCI). The 2026 rule uses a plan that gives gas money for non-medical transportation on a flex card as its example, and says the plan must decide eligibility on objective criteria. A member cannot qualify by checking a box.

Plans can cap each benefit by month, by year, or over another period inside the plan year, and a plan can set one combined cap across several benefits. CMS notes that with a combined allowance, using the card for one benefit can mean giving up another. Starting January 1, 2027, plans must also post the objective criteria for each SSBCI on their public websites.

Why does a flex card decline at a ride company?

A decline means the plan or the card issuer did not allow that purchase at that business. There are four common reasons:

• The card does not cover rides. A card is linked only to the items and services the plan covers on it. If rides are not among them, the card declines.
• The plan restricts where it works. CMS says plans can limit cards through merchant codes, inventory approval system codes or other mechanisms. It notes that many plans now work through financial technology companies that oversee card use, which affects which vendors can take part.
• Your merchant category code is not on the plan’s list. A merchant category code (MCC) is a four-digit number that describes your primary business. Visa’s April 2026 manual says the acquirer, the bank or processor behind your card sales, assigns it. Three transportation codes matter here. MCC 4121 is taxicabs and limousines, defined as transportation by automobile that does not run on a regular schedule or route. MCC 4119 is ambulance services, which Visa defines as emergency vehicle transportation with trained personnel. MCC 4789 covers passenger transportation not classified under a more specific code. For example, a plan that allows only 4121 would decline a business coded 4789.
• The balance or cap is used up. The card holds only the allowance the plan loaded, and it may be split across benefits.

Ask your processor which code your account carries. Visa requires it to describe your main business. HSA and FSA cards follow different rules, covered in our guide to charging riders by card.

What changes on January 1, 2027?

Plans that use debit cards must meet four requirements that CMS wrote into the regulation in a rule published April 6, 2026 (91 FR 17384), effective June 1, 2026 and applicable to coverage beginning January 1, 2027. They are in the new 42 CFR 422.102(g)(2):

1. A real-time check at the point of sale. The card has to be electronically linked to plan-covered items and services through a mechanism that verifies eligibility at the register. CMS does not count manual verification as real time, though plans may use it as a backup when systems fail. It does not prescribe the technology.
2. Instructions and customer service. The plan must give members instructions for using the card and a service line for help.
3. A way to be reimbursed when the card does not work. If the card is unusable at the point of sale, for a malfunction or because the member can go out of network, the plan must have another process that reimburses eligible expenses. CMS describes it as reimbursement based on submitted receipts.
4. A plan-year limit. The card is limited to the specific plan year. The same physical card can be used again, but the dollar amounts on it cannot carry over. CMS says its position on plan-year limits goes back to 2021, and the rule writes it into the regulation.

None of this makes a plan accept your business. CMS says the law bars it from requiring a plan to contract with a particular vendor, supplemental benefits included, so a ride company is on a card only when the plan or its card administrator allows it.

What should a rider get from you if the card fails?

An itemized receipt, so the rider can ask the plan to reimburse the expense. Under the rule above, the plan must offer that route when the card is unusable at the point of sale. CMS’s manual already required that for over-the-counter items when the card network is not operating correctly, and the 2026 rule extends the idea to every benefit on a card. The plan’s customer service tells the rider what documents it wants, so a full receipt serves any version of the form. Put these on it:

• The date and the pickup and drop-off addresses
• The service, such as one-way wheelchair van, and the miles
• The amount, how it was paid, and the balance if the rider paid only part
• Your business name, address and phone number

Leave diagnoses and other health details off. Our guide to charging riders by card covers what a card receipt should and should not show.

Taking card payments in HealthRide

Card payments in HealthRide go through a secure card processor, and a rider can pay from a pay link or a saved card. Each payment sits against the trip’s invoice, and an invoice built from the completed trip lists the date, pickup, drop-off and charge, so the details a rider needs for a receipt are on hand.
