If you rely on Medicare to cover your doctor visits — and most people over 65 do — a set of federal policy changes scheduled for 2027 deserves your attention. The Medical Group Management Association (MGMA), which represents physician practices across the country, has outlined a coming reduction in Medicare physician reimbursement rates alongside the planned elimination of the Merit-based Incentive Payment System, commonly known as MIPS. While these changes are aimed at physicians and their practices, the downstream effects will land squarely on patients — particularly Medicare beneficiaries who depend on a stable network of doctors willing to accept Medicare's payment rates.

To understand why this matters, it helps to know how Medicare pays doctors. Under traditional Medicare (Parts A and B), physicians are reimbursed according to the Medicare Physician Fee Schedule, a complex formula updated annually by the Centers for Medicare & Medicaid Services (CMS). For years, that formula has produced flat or declining payment rates when adjusted for inflation and practice costs. The MGMA has repeatedly warned that these rates have not kept pace with the actual cost of running a medical practice — staff salaries, malpractice insurance, electronic health record systems, and overhead have all risen sharply. A projected pay cut in 2027 would compound that pressure, potentially making it financially untenable for some practices to continue seeing Medicare patients at current volumes.

According to CMS.gov data, more than 1.3 million physicians and other healthcare professionals were enrolled as Medicare providers as of recent reporting years. However, the share of physicians who are 'participating' providers — meaning they accept Medicare's approved amount as payment in full — has been a point of ongoing concern. When reimbursement rates fall, some physicians respond by reclassifying as 'non-participating,' which allows them to charge patients up to 15 percent above Medicare's approved amount (known as an 'excess charge'). Others choose to opt out of Medicare entirely, billing patients directly at whatever rate they set. For a beneficiary on a fixed income, either of those outcomes can mean significantly higher out-of-pocket costs or losing access to a trusted physician altogether.

The end of MIPS is a separate but related development. MIPS was created under the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) as a way to tie a portion of physician pay to quality metrics, cost efficiency, and the use of electronic health records. Physicians who scored well on MIPS could receive a small payment bonus; those who scored poorly faced penalties. The system was widely criticized by physician groups as administratively burdensome and poorly designed — many small and solo practices found the reporting requirements overwhelming without producing meaningful improvements in patient care. The MGMA has long advocated for MIPS reform or elimination, and the 2027 timeline represents a significant structural shift in how Medicare evaluates and compensates physicians.

What replaces MIPS matters for patients too. CMS has been moving toward Alternative Payment Models (APMs), which are arrangements where physician groups take on some financial risk in exchange for potentially higher payments if they deliver care efficiently. Accountable Care Organizations (ACOs) are the most common example. In theory, APMs can align physician incentives with better patient outcomes. In practice, the transition creates uncertainty — particularly for smaller practices that may not have the infrastructure to participate in APMs and may face steeper payment cuts as a result. Beneficiaries whose doctors are in smaller, independent practices should pay close attention to whether those practices remain financially viable through 2027 and beyond.

For Medicare Advantage enrollees specifically, the physician payment changes in traditional Medicare create a complicated ripple effect. Medicare Advantage plans — offered by private insurers and covering more than 33 million beneficiaries in 2024 according to CMS.gov data — negotiate their own reimbursement rates with physicians, which are typically higher than traditional Medicare rates. This has historically made Medicare Advantage networks somewhat more attractive to physicians. However, Medicare Advantage plans are themselves under reimbursement pressure from CMS, with rate adjustments in recent years that have caused some insurers to narrow their networks, exit markets, or increase cost-sharing. If both traditional Medicare and Medicare Advantage are squeezing physician payments simultaneously, the access problem for patients could intensify regardless of which coverage type you have.

Data Snapshot: According to CMS.gov data from the 2024 Medicare Advantage landscape files, there were 7,543 Medicare Advantage plans available nationwide for the 2024 plan year, with an average monthly premium of approximately $18.50 for plans that include Part D drug coverage. The average Medicare Part B premium in 2024 was $174.70 per month. These figures illustrate the scale of the Medicare ecosystem — and why physician payment policy changes that affect provider participation can have enormous consequences for tens of millions of beneficiaries who depend on stable, accessible networks.

So what can you do right now, before 2027 changes take effect? The most important first step is to verify your current doctors' Medicare participation status. You can do this at Medicare.gov using the 'Find care' tool, which shows whether a provider is a participating, non-participating, or opt-out physician. If your doctor is already non-participating, you may be paying excess charges without realizing it — and a Medigap (Medicare Supplement) plan that covers excess charges, such as Plan G or Plan N (Plan N does not cover excess charges, Plan G does), can protect you from those costs. If your doctor has opted out entirely, Medicare will not pay anything toward their services, and you are responsible for the full bill.

For beneficiaries currently enrolled in Medicare Advantage, now is a good time to review your plan's provider directory and confirm that your primary care physician and key specialists are still in-network for the upcoming plan year. Medicare Advantage plans update their networks annually, and a doctor who was in-network in 2025 or 2026 may not be in 2027. The Annual Enrollment Period (AEP) runs from October 15 through December 7 each year, and this is your primary window to switch Medicare Advantage plans or return to traditional Medicare if your network has changed in ways that affect your care. The Open Enrollment Period (OEP), which runs January 1 through March 31, allows one additional switch from one Medicare Advantage plan to another, or back to traditional Medicare, if you need to make a change after the AEP closes.

If you are on traditional Medicare and concerned about physician access, this is also a good time to evaluate whether a Medigap policy makes sense for your situation. Medigap Plan G is currently the most comprehensive plan available to new enrollees (Plan F was discontinued for those who became Medicare-eligible after January 1, 2020), and it covers the Part A deductible, Part B coinsurance, skilled nursing facility coinsurance, and — critically — Part B excess charges. If more physicians shift to non-participating status in response to 2027 pay cuts, having a plan that covers excess charges could save you hundreds or even thousands of dollars annually. Average Medigap Plan G premiums vary significantly by state and age, but typically range from roughly $100 to $200 per month for a 65-year-old, according to industry data — a cost that may be worth comparing against your current out-of-pocket exposure.

State-level protections also vary in ways that matter here. Thirteen states — including California, New York, Oregon, and Illinois — have 'birthday rule' provisions that allow Medigap enrollees to switch to an equal or lesser plan once per year during a 30-day window around their birthday, without medical underwriting. This means beneficiaries in those states have more flexibility to adjust their Medigap coverage as the physician payment landscape shifts. If you live in one of these states and have been putting off reviewing your Medigap plan, the period leading up to 2027 is a practical time to reassess.

The broader policy picture is one of ongoing tension between federal budget pressures and the sustainability of Medicare as a program that physicians are willing to participate in. Congress has repeatedly passed last-minute 'doc fixes' to prevent scheduled payment cuts from taking effect — a pattern that has played out almost annually for two decades. It is possible that the 2027 cuts will be partially or fully offset by legislative action, as has happened before. However, relying on that outcome is not a strategy. Physician groups are already signaling that the cumulative effect of years of flat or declining reimbursement, combined with the administrative burden of quality reporting programs, is pushing more practices toward consolidation with hospital systems or toward direct-pay and concierge models that exclude Medicare patients entirely.

For Medicare beneficiaries, the practical takeaway is this: your access to physicians is not guaranteed simply because you have Medicare coverage. The quality and breadth of that access depends on how many physicians are willing to accept Medicare's payment terms — and that willingness is directly tied to the reimbursement rates and administrative requirements that federal policy sets. Staying informed about these changes, verifying your providers' participation status, and using the annual enrollment windows to make sure your coverage aligns with your actual care needs are the most effective tools available to you. Speaking directly with your physician's billing office about their Medicare participation plans for 2027 is also a reasonable step — most practices will be transparent about this, and knowing in advance gives you time to plan.
