Medicare sets different payment rates for the same service depending on where you live

A doctor's office visit, a hospital stay, or a physical therapy session costs Medicare — and costs you — different amounts in different states. The same procedure that Medicare pays $500 for in rural Mississippi might cost $800 in Massachusetts. This is not random variation or a mistake. It is built into how Medicare calculates what it will pay.

The variation matters because it affects your out-of-pocket costs. If your doctor charges based on what Medicare pays in your state, a higher Medicare rate means a higher bill for you. It also affects which providers stay in your area — doctors and hospitals sometimes leave regions where Medicare payments are too low to sustain their practice.

Understanding why these differences exist helps you understand your own bills and why healthcare costs what it does where you live.

Key Takeaways

  • Medicare uses a formula called the Geographic Practice Cost Index (GPCI) that adjusts payment rates based on local costs for labor, equipment, rent, and malpractice insurance in each state and region.
  • States with higher costs of living — like New York, California, and Massachusetts — receive higher Medicare payment rates than states with lower costs of living.
  • Rural areas within states often receive lower rates than urban areas in the same state, even though rural providers may have higher overhead costs per patient.
  • These rate differences have existed for decades and are adjusted annually, but the gaps between high-paying and low-paying states have remained relatively stable.
  • Your actual out-of-pocket cost depends on whether your provider accepts Medicare's rate as full payment or charges you the difference.

How the Geographic Practice Cost Index sets rates by location

Medicare does not set one national price for a doctor's visit or a hospital procedure. Instead, it calculates a base payment amount and then multiplies it by a location adjustment factor. That factor is called the Geographic Practice Cost Index, or GPCI.

The GPCI measures four things: the cost of physician work (salaries and benefits), the cost of practice expenses (rent, equipment, staff), the cost of malpractice insurance, and adjustments for local economic conditions. A state or region where these costs are high gets a higher multiplier. A state where they are low gets a lower one.

For example, if the base Medicare payment for a particular service is $100, and your state's GPCI multiplier is 1.15, Medicare pays $115. If you live in a state with a GPCI of 0.85, Medicare pays $85 for the same service. The difference compounds across thousands of services and millions of claims.

Why some states have higher costs than others

States with higher costs of living — particularly in the Northeast, California, and parts of the Midwest — have higher GPCI values. This reflects real differences in what it costs to run a medical practice. Rent for a medical office in Boston is higher than rent in rural Kansas. Physician salaries are higher in high-cost states. Malpractice insurance premiums vary by state and specialty.

Medicare's formula tries to account for these real differences so that doctors in expensive areas are not forced to operate at a loss. Without the adjustment, many providers in high-cost states would stop accepting Medicare patients.

However, the formula does not always match the actual costs providers face. Rural areas often have lower GPCI values even though rural providers may have higher costs per patient — they see fewer patients spread across larger geographic areas, which raises overhead per visit. Some rural hospitals and clinics have closed partly because Medicare payments in their regions do not cover their actual costs.

The difference between urban and rural rates within the same state

State-level variation is only part of the story. Medicare also adjusts rates within states, paying more in urban areas and less in rural ones. A cardiologist in downtown Chicago receives a higher Medicare rate than a cardiologist 50 miles away in a rural county, even though both are in Illinois.

This urban-rural split reflects the assumption that urban areas have higher costs. But it creates a problem: rural areas already struggle to attract and keep doctors. Lower Medicare rates make that problem worse. Some rural hospitals have closed in recent years partly because Medicare payments fell below operating costs.

Congress has tried to address this through programs like the Rural Hospital Flexibility Program and temporary payment boosts for rural providers, but the core GPCI formula still favors urban areas.

How annual updates affect state-to-state differences

Medicare updates its GPCI values every year, usually in the fall, based on new cost data. These updates can shift rates up or down for individual states. However, the relative gaps between high-paying and low-paying states have stayed fairly stable over decades.

A state that ranks in the top 10 for Medicare payment rates in one year usually ranks in the top 10 the next year. The same is true for low-paying states. This stability means that if you move from one state to another, you can expect the payment rate difference to be roughly similar to what it was the year before.

Updates also include a national adjustment factor that Congress sometimes modifies. In recent years, Congress has frozen or reduced the national update to control Medicare spending, which means all states see smaller increases — or no increase — even if their local costs rise.

What this means for your out-of-pocket costs

The Medicare payment rate in your state affects what you pay in two ways. First, if your provider accepts Medicare's rate as full payment (called accepting Medicare assignment), you pay only your copay or coinsurance based on that rate. Second, if your provider does not accept assignment, they can charge you the difference between their fee and what Medicare pays.

In states with lower Medicare rates, providers are more likely to either refuse Medicare patients or charge balance-billing fees. In states with higher rates, more providers accept Medicare assignment because the payment covers their costs.

You can ask your doctor before your visit whether they accept Medicare assignment. If they do not, ask what their full fee is so you know your total cost. You can also check the Medicare.gov provider directory, which shows whether a provider accepts assignment.

How state rates affect provider availability in your area

Over time, payment rate differences shape which doctors and hospitals stay in which states. Providers in low-paying states face a choice: accept lower Medicare payments, limit the number of Medicare patients they see, or leave the state for a higher-paying region.

Some specialties are more sensitive to payment rates than others. Orthopedic surgeons and cardiologists, who have high overhead and can often choose where to practice, are more likely to leave low-paying states. Primary care doctors, who have fewer options and often feel obligated to serve their communities, are more likely to stay even when payments are low.

This creates a long-term effect: states with lower Medicare rates tend to have fewer specialists and longer wait times for appointments. If you need a specialist in a low-paying state, you may have to travel or wait months for an opening.

Frequently Asked Questions

Can I get a higher Medicare rate by moving to a different state?

Your Medicare benefits and coverage follow you wherever you live, but the payment rates your providers receive will change. If you move to a higher-paying state, your providers will receive higher Medicare rates, which may make them more willing to see you or less likely to charge balance-billing fees. However, you cannot change your Medicare rate directly — it is determined by where your provider is located, not where you live.

Why does Medicare not just pay the same amount everywhere?

A single national rate would not work because costs genuinely differ by location. A medical office in New York City has much higher rent than one in rural Montana. If Medicare paid the same amount everywhere, providers in high-cost areas would lose money and many would stop accepting Medicare patients. The GPCI tries to balance fairness with the reality that running a medical practice costs different amounts in different places.

Do state Medicare rates ever change?

Yes, Medicare updates its GPCI values every year based on new cost data from each state and region. However, the updates are usually small — a few percentage points — and the relative ranking of states stays roughly the same. Congress also sometimes changes the national payment update, which affects all states together.

How do I find out what Medicare pays in my state?

You can search the Medicare Physician Fee Schedule on the Centers for Medicare & Medicaid Services (CMS) website. It shows the payment amount for specific services in your state. You can also ask your doctor's office what Medicare pays for a particular service — they have access to this information and can tell you in most cases.

If my state has a low Medicare rate, will I pay more out of pocket?

You may. If your provider accepts Medicare assignment, you pay only your copay or coinsurance, which is the same percentage nationwide. But if your provider does not accept assignment, they can charge you the difference between their fee and what Medicare pays. In low-paying states, more providers do not accept assignment, so balance-billing is more common. Always ask your provider before your visit.
