A Relative Value Unit, or RVU, is a standardized measure that Medicare uses to determine how much a physician gets paid for a specific service. Every medical procedure and office visit has an assigned RVU value that reflects the resources required to provide it. A complex surgery carries more RVUs than a routine checkup, and those RVU values translate directly into dollars. For 2025, each RVU is worth $32.35, meaning a service assigned 5 total RVUs would generate roughly $161.75 in Medicare payment before geographic adjustments.
The Three Components of an RVU
Every RVU is actually built from three separate components, each capturing a different cost of delivering care.
Physician work is typically the largest piece. It accounts for the physician’s expertise, time, technical skill, and mental effort before, during, and after a patient encounter. A 15-minute office visit for a straightforward problem carries a lower work RVU than a 45-minute visit requiring complex medical decision-making. Documentation time is included here too.
Practice expense covers the overhead costs of running a medical office: staff salaries, rent, medical supplies, and equipment. A procedure performed in a physician’s own office carries a higher practice expense RVU than the same procedure done in a hospital, because the physician’s practice absorbs more of those costs directly. Supplies and equipment, however, are not adjusted geographically since they’re purchased in a national market where prices are relatively uniform.
Malpractice reflects the cost of professional liability insurance for that type of service. A high-risk procedure like brain surgery carries a higher malpractice RVU than a routine wellness visit, because the insurance premiums associated with those services differ dramatically.
How RVUs Become Dollars
The payment formula is straightforward in concept, even if the numbers get complicated in practice. Medicare multiplies each of the three RVU components by a geographic adjustment factor, then adds them together and multiplies the total by a single national number called the conversion factor.
The conversion factor is the dollar amount assigned to one RVU. For 2025, that number is $32.35, down about 3 percent from the prior year’s $33.29. This single number shifts every year based on federal policy decisions and budget requirements, which means every physician’s Medicare payments move with it.
The geographic adjustments, known as Geographic Practice Cost Indexes (GPCIs), exist because practicing medicine in Manhattan costs more than practicing in rural Kansas. Each Medicare payment area has its own GPCI for all three RVU components. The work GPCI reflects cost-of-living differences, though Congress limited it to just one-quarter of the actual variation in professional earnings across regions. The practice expense GPCI draws on real data: median wages for nurses, technicians, and administrative staff from the Bureau of Labor Statistics, plus apartment rental data from the Department of Housing and Urban Development as a proxy for office rent. The malpractice GPCI uses actual premium data collected from state insurance commissioners and private insurers across 25 physician specialties.
So a physician in San Francisco performing the same service as a physician in rural Mississippi will receive a higher Medicare payment, not because the service is valued differently, but because it costs more to deliver care there.
Who Decides the RVU Values
The American Medical Association runs a committee called the RVS Update Committee, or RUC, which recommends RVU values for every CPT code (the billing codes that represent medical services). The RUC is a multispecialty panel that evaluates the time, skill, and resources each service requires. Their recommendations go to the Centers for Medicare and Medicaid Services, which has the final say on published RVU values through the annual Medicare Physician Fee Schedule.
This process has been contentious for years. Procedure-heavy specialties like surgery and cardiology have historically been assigned higher RVUs relative to the time involved, while cognitive specialties like internal medicine and psychiatry, where the “work” is mostly thinking, talking, and coordinating, have argued their services are systematically undervalued. The committee’s composition and voting patterns have a real impact on which types of medicine are most financially rewarded.
RVUs as a Pay and Productivity Measure
Beyond Medicare reimbursement, RVUs have become the dominant way hospitals and health systems measure physician productivity and structure compensation. Most employed physicians in the United States have at least some portion of their pay tied to the number of work RVUs (wRVUs) they generate. A physician producing 5,000 wRVUs per year earns more than one producing 4,000, regardless of whether those RVUs came from seeing more patients, performing more procedures, or billing at higher complexity levels.
This system has clear advantages. It creates a standardized way to compare productivity across specialties and practices. It gives administrators a concrete metric to evaluate staffing needs. And it provides physicians with transparent targets.
The downsides are equally clear. When compensation is tied primarily to RVU production without quality counterweights, physicians face pressure to maximize volume. Research consistently shows that RVU-based compensation models lead to increases in service volume. That pressure can encourage unnecessary visits or procedures, prioritize throughput over thoughtful patient-centered care, and contribute to physician stress and burnout. A system designed to standardize payment can, in practice, turn medicine into piecework.
Many health systems now blend RVU-based pay with quality metrics, patient satisfaction scores, or salary guarantees to balance productivity incentives against care quality. But the wRVU remains the backbone of physician compensation in most settings.
Recent Changes Worth Knowing
The RVU landscape shifts every year with the Medicare Physician Fee Schedule update. For 2026, all physicians will see a positive conversion factor update: a 3.26 percent increase for most physicians, and 3.77 percent for those in advanced alternative payment models. That’s a reversal from several years of flat or declining conversion factors.
One notable policy change for 2026 is that CMS will reduce work RVUs for certain non-time-based services it believes have become more efficient over time due to technology or practice changes. Time-based services like evaluation and management visits, care management, maternity care, and telehealth services are exempt from these cuts.
The overall impact varies by practice setting. Payment for physician services performed in facilities (hospitals, ambulatory surgery centers) will decrease by about 7 percent overall, while payment for services in non-facility settings like private offices will increase by 4 percent. For individual practices, the swings can be steeper in either direction depending on their specialty and service mix.
