Medical Care CPI

Medical inflation briefly went negative in late 2023. The print was unusual. It reflected a methodology change in how the BLS measures health insurance prices, combined with Medicare drug negotiation effects feeding through to the pharmaceutical component. Both factors were temporary.

The index has since reverted. BLS data shows medical care CPI at roughly 3.2 percent year-over-year as of March 2026. Still above the Fed's inflation target and back on the structural trend that has defined healthcare costs for four decades.

The driver is the services side: doctor visits, hospital services, outpatient procedures, and especially insurance premiums. Drugs are actually deflating right now. Services are doing all the work as insurers pass through rising claim costs. These categories compound year after year. A 3 percent annual rate on medical care translates into cost doubling roughly every 24 years, independent of whatever is happening to the rest of the economy.

The household consequence shows up in places like The Safety Net, where the share of Americans who could cover a $1,000 emergency from savings has fallen to 41 percent. Medical bills remain one of the most common triggers for those emergencies and one of the most common precursors to the bankruptcy filings tracked in Bankruptcy Filings.
