Millions of people enrolled in a Medicare Advantage plan carry a prepaid debit card meant to cover groceries, over-the-counter items, or other extra benefits the plan advertised at enrollment. Starting with the 2027 plan year, that card will work differently at the register: a federal rule finalized this spring requires it to check, in real time, whether an item actually qualifies before the purchase goes through. The change closes a gap that let some purchases clear the checkout line even when they fell outside what a plan had agreed to cover, and it arrives paired with a second requirement that decides what happens to any balance left on the card once the plan year ends.
The Point-of-Sale Check CMS Finalized for Grocery and OTC Cards
The Centers for Medicare & Medicaid Services finalized the requirement inside its Contract Year 2027 Medicare Advantage and Part D rule, issued April 2, 2026. According to the agency’s fact sheet on the rule, plans that issue supplemental-benefit debit cards must electronically link each card to the specific products and services the plan actually covers, using a real-time identification mechanism that verifies eligibility “at the point of sale.” That shifts the eligibility check to the cash register itself rather than leaving it to a plan’s claims department to sort out afterward.
The same rule tightens one specific category of purchase: cannabis products that remain illegal under state or federal law cannot be charged to a card issued for Special Supplemental Benefits for the Chronically Ill, regardless of how an individual plan designed that benefit. CMS described the change as a clarification of existing policy rather than a new restriction, aimed at closing daylight that had opened between state marijuana laws and federal Medicare rules.
Notably, CMS pulled back from one piece of what it originally proposed. The Federal Register text finalizing the debit-card provisions notes the agency is “finalizing this proposal with modifications, including not finalizing the proposed prohibition on marketing the dollar value of supplemental benefits.” Plans keep the ability to advertise a card’s dollar amount when marketing a benefit; the point-of-sale eligibility check, not a marketing restriction, is doing the work of keeping purchases inside what a plan actually covers.

Why a Leftover Balance Won’t Carry Into the Next Plan Year
The same final rule requires that supplemental-benefit debit cards be limited to the specific plan year in which they were issued. A household that has not spent down a grocery or OTC allowance by the close of the plan year will not see that balance carry forward once a new plan year begins on January 1. The final rule as published in the Federal Register sets the regulation’s effective date as June 1, 2026, with the debit-card and eligibility provisions applicable to coverage beginning January 1, 2027 — the plan year the industry already refers to as CY2027.
For a household budgeting around a plan’s advertised grocery or utility allowance, that plan-year cutoff turns what has often functioned like a rolling perk into something closer to a use-it-by-December benefit. A card loaded with an unused balance in November carries real pressure to spend it before the calendar turns, since the CY2027 rule gives plans no obligation to extend it into January.
Plans Must Now Publish Who Actually Qualifies
CMS paired the point-of-sale requirement with a transparency rule: Medicare Advantage plans must publicly post the eligibility criteria they use to decide who qualifies for their chronically-ill supplemental benefits, rather than keeping those standards internal to customer-service scripts or plan documents an enrollee has to request. The agency’s fact sheet frames the posting requirement as part of the same effort to standardize how debit-card benefits are administered across the roughly two-thirds of Medicare beneficiaries now enrolled in a Medicare Advantage plan.
The posting requirement does not change who is medically eligible for a chronic-illness supplemental benefit. It changes whether a household can check a plan’s own published criteria before enrolling or before assuming a particular grocery or OTC allowance applies to a given diagnosis.
One Piece of a Broader Regulatory Reset for 2027
The debit-card and eligibility-posting provisions arrived inside a much larger rule that also revises the Part C and Part D Star Ratings measure set, codifies several Inflation Reduction Act changes to the Part D drug benefit that CMS had previously implemented only through program instructions, and rolls back a list of administrative requirements the agency says added cost without improving care. CMS had proposed the debit-card and transparency provisions a year earlier, in the Contract Year 2026 proposed rule, before finalizing them as part of the CY2027 package.
The drug-benefit piece of the same rule carries its own household consequence. CMS is codifying the elimination of Part D’s old coverage gap phase, a reduced annual out-of-pocket threshold, and no cost-sharing once an enrollee reaches the catastrophic phase, on top of folding in the Manufacturer Discount Program that replaced the earlier Coverage Gap Discount Program on January 1, 2025. On the quality side, CMS is not implementing the reward it had called the Excellent Health Outcomes for All measure, choosing instead to keep the older reward factor that credits consistently high performance across every quality measure, while trimming eleven administrative measures out of the Star Ratings system plans use to earn quality bonus payments.
The Federal Register notice lists CMS’s Kristy Nishimoto as the contact for questions on the rule, a marker that the debit-card and eligibility provisions are now final regulatory text rather than a proposal still open for comment. For a household that has grown used to treating a Medicare Advantage grocery card like a gift card, that finalized text is what will greet the next declined purchase at the register.
Medicare’s Other Programs With Their Own Eligibility Tests
The gap this rule closes is really one of information: a household often learns what its plan actually covers only when a purchase is declined at the register. The programs that sit outside a plan entirely work the same opt-in way. Medicare Savings Programs cover the Part B premium and Extra Help lowers Part D drug costs, and each runs on its own income and asset test that nobody files on a household’s behalf.
