Medicare hospital stays and outpatient procedures in device groups
Official US government data: Original Medicare claims of doctors, surgery centers and suppliers (yearly), Medicare hospital stays and outpatient services, and the medical device clearances, approvals, recalls and adverse event reports (updated weekly). Device categories are our reviewed grouping of procedure codes. Procedures are counted once: assistant surgeons, technical components and surgery center facility claims are not counted again. Procedure codes are shown by number with their category, because the official code descriptions are licensed.
How often Medicare pays for knee and hip replacements, pacemakers, heart valves, stents, spine fusions, cataract lenses and other device procedures, where they happen, and the approvals, recalls and adverse event reports of the companies that make the devices.
Medicare procedure counts come from 100% of Original Medicare claims of doctors and surgery centers. A procedure is counted once, even when an assistant surgeon or a second doctor bills for it. Device categories are our grouping of procedure codes. Hospital stays use the diagnosis related groups (DRG) that center on a device, such as joint replacement and pacemaker implants.
In California hospital stays, knee replacement procedure codes were reported 16,027 times and hip replacement codes 23,888 times in 2025, for patients of every payer, not only Medicare. This count is for California only.

Imaging aside, the largest device categories in 2025 were heart monitors and device checks (11.9M procedures), eye lenses and glaucoma devices (1.7M procedures), diabetes devices (1.0M procedures), vascular and endovascular (938K procedures), spine fusion and implants (780K procedures). In all, 171.3M device procedures and scans with $15.37B in Medicare payments to doctors.
2,838 medical device products were recalled in 2025, in 945 recall actions. 377 of them were class I, the most serious kind, where using the device could cause serious harm or death.
By recalled products since the records began: Zimmer Biomet (ZBH): 3,080 recalled products, 5 class I; Stryker (SYK): 2,728 recalled products, 17 class I; Medtronic (MDT): 2,538 recalled products, 491 class I; Philips (PHG): 2,420 recalled products, 130 class I; Johnson & Johnson (JNJ): 1,815 recalled products, 79 class I. Large makers sell many more devices, so counts are not risk rates.
