What is GPCI?

The Geographic Practice Cost Index (GPCI) is a set of adjustment factors created by the Centers for Medicare & Medicaid Services (CMS) to reflect the relative cost of practicing medicine in different parts of the United States. Because the cost of living, wages, rent, and insurance premiums vary dramatically by region, CMS uses GPCIs to ensure that Medicare payments to physicians are fair and reflect local economic conditions.

GPCI values are updated annually as part of the Medicare Physician Fee Schedule (MPFS) Final Rule, typically published each November for the following calendar year. The values are derived from economic data sources including the Bureau of Labor Statistics, the American Community Survey, and state insurance commissioner reports.

There are three separate GPCI components, each adjusting a different part of the physician payment formula: Work GPCI, Practice Expense GPCI, and Malpractice GPCI. Together, these three factors ensure that the total Medicare reimbursement for any given procedure accounts for where it was performed.

The Three GPCI Components

1. Work GPCI

The Work GPCI adjusts for geographic differences in the cost of physician labor. It reflects wage differences for the time, effort, skill, and stress involved in providing medical services. Congress has set a statutory floor of 1.000 for the Work GPCI, meaning no locality pays less than the national average on the work component. In practice, Work GPCI values range from 1.000 (the floor for most areas) to about 1.100 for high-cost metropolitan areas, with Alaska being the notable exception at 1.500.

2. Practice Expense (PE) GPCI

The PE GPCI adjusts for geographic differences in the cost of maintaining a medical practice, including office rent, staff wages, medical equipment, and supplies. This is typically the most variable component, ranging from about 0.85 in lower-cost rural areas to over 1.40 in expensive metropolitan markets like San Francisco and San Jose. The PE GPCI has the largest impact on total payment for most procedure types.

3. Malpractice (MP) GPCI

The MP GPCI adjusts for geographic differences in professional liability insurance premiums. This component shows the widest range of all three GPCIs, from as low as 0.30 in states with tort reform (like South Carolina) to over 2.40 in areas with high malpractice costs (like Miami, FL). Malpractice insurance costs are driven by state legal environments, jury award patterns, and specialty risk profiles.

How GPCI Affects Your Reimbursement

The Medicare physician payment formula incorporates GPCI values by multiplying each RVU component by its corresponding GPCI before applying the conversion factor:

// Medicare Payment Formula

Payment = [(Work RVU × Work GPCI)

+ (PE RVU × PE GPCI)

+ (MP RVU × MP GPCI)]

× Conversion Factor ($33.29)

Example: Consider a 99214 office visit in Manhattan, NY vs. rural Alabama:

Manhattan, NY

Work: 1.92 × 1.094 = 2.100

PE: 1.07 × 1.316 = 1.408

MP: 0.10 × 1.657 = 0.166

Total: 3.674 RVUs × $33.29 = $122.31

Alabama

Work: 1.92 × 1.000 = 1.920

PE: 1.07 × 0.878 = 0.939

MP: 0.10 × 0.590 = 0.059

Total: 2.918 RVUs × $33.29 = $97.14

The same procedure in Manhattan pays $25.17 more (26% higher) than in Alabama, entirely due to geographic cost differences reflected in the GPCI.

Highest and Lowest GPCI Areas

Top 5 Highest PE GPCI

San Jose, CA 1.435
San Francisco, CA 1.408
Manhattan, NY 1.316
Queens, NY 1.228
Washington, DC 1.226

High PE GPCI areas correlate with expensive real estate markets and higher staff wages, concentrated in coastal metropolitan areas.

Top 5 Lowest PE GPCI

Arkansas 0.852
Mississippi 0.852
West Virginia 0.859
Rest of Missouri 0.861
Rest of Louisiana 0.862

Low PE GPCI areas reflect lower costs of doing business in rural and Southern states, where rent, wages, and supplies are less expensive.

Frequently Asked Questions

GPCI stands for Geographic Practice Cost Index. It is a set of three adjustment factors used by Medicare to modify physician payments based on geographic location. The three components -- Work, Practice Expense, and Malpractice -- each adjust a different part of the RVU-based payment formula. When a physician performs a procedure, the base RVU values are multiplied by the GPCI for their locality before the conversion factor is applied to determine the final Medicare payment.
GPCI directly scales physician reimbursement up or down based on where services are delivered. A locality with GPCI values above 1.0 will receive higher payments than the national average, while areas below 1.0 will receive less. For example, a physician in San Francisco might receive 15-20% more for the same procedure compared to a physician in a rural Southern state. This impacts not only Medicare payments but also many private insurance contracts that base their fee schedules on the Medicare GPCI-adjusted rates.
It depends on which GPCI component you are looking at. Alaska has the highest Work GPCI at 1.500. California localities (San Jose and San Francisco) have the highest Practice Expense GPCI values at 1.435 and 1.408 respectively. Florida (specifically Miami at 2.432) has the highest Malpractice GPCI, reflecting extremely high malpractice insurance premiums in that area. For the overall highest combined GPCIs, Manhattan, NY and Alaska consistently rank near the top.
The GPCI floor is a statutory provision that sets the minimum Work GPCI at 1.000. This means that no matter how low the cost of physician labor is in a given area, the Work GPCI cannot go below the national average. This floor was enacted by Congress to protect physicians in lower-cost areas from reduced work payments. Note that only the Work GPCI has a floor; the Practice Expense and Malpractice GPCIs can fall below 1.0, which is why many rural localities have PE and MP values significantly below the national average.
CMS updates GPCI values annually as part of the Medicare Physician Fee Schedule (MPFS) final rule, which is typically released in November and takes effect January 1 of the following year. However, the underlying data and methodology undergo major revisions approximately every 3-5 years. Changes from year to year tend to be modest for most localities, but major methodology updates can result in more significant shifts in GPCI values.
