The headline numbers
CMS actuaries reported on Jan. 14 in Health Affairs that U.S. health spending reached $5.3 trillion in 2024, up 7.2%, or about $15,474 per person. Health care now accounts for 18% of gross domestic product, up from 17.7% a year earlier. Hospital care, the largest category, grew 8.9%. Physician and clinical services rose 8.1% to $1.1 trillion and prescription drugs rose 7.9% to $467 billion.
By payer, private insurance spending climbed 8.8% to $1.6 trillion, Medicare rose 7.8% to $1.1 trillion and Medicaid grew 6.6% to about $932 billion. The insured share of the population slipped to 91.8% from a peak of 92.5% in 2023.
What drove hospital growth
The actuaries attribute most of the overall increase to use and intensity of services rather than price. Of the 7.2-point rise, roughly 3.6 points came from non-price factors, about 2.5 from prices and about 1 from population growth. For hospitals specifically, discharges rose 3.2% and inpatient days 1.5%, reflecting a continued rebound in service use after the pandemic and more complex care.
Prices still matter. Hospital prices rose 3.4% in 2024, the fastest increase since 2007. That figure will travel quickly in debates over site-neutral payment, price transparency and employer costs.
What this means for leadership teams
- Expect the price figure to be used against you. Employers, insurers and lawmakers will cite the 3.4% hospital price increase. Leaders should have a clear account of their own price trends, cost drivers and margins.
- Volume is a strategic asset and a risk. Demand rose in 2024, but much of the 2025 and 2026 outlook depends on coverage. A falling insured rate and the lapse of enhanced ACA premium subsidies could shift more volume to self-pay and charity care.
- Know your payer mix trajectory. Among major payers, private insurance spending grew fastest in 2024. Systems that rely on commercial margins to offset public payer shortfalls should stress-test what happens if that growth slows.
- Use the data in public messaging. The actuaries’ finding that utilization drove most growth supports a hospital narrative about rising demand and acuity. Pair it with local evidence of access, quality and community benefit.
National spending data arrive with a lag, but they shape the arguments policymakers make now. Boards should treat this report as a preview of the questions they will face this year.
