Bundling
Updated September 30, 2026
Definition
Grouping related services under 1 billing code or 1 payment. A service that's part of a bigger one usually shouldn't show up again as its own charge.
Bundling means grouping related services together for billing. Many procedures include small steps, like supplies or a simple test, that are part of the main service. Those steps are paid as part of the main code, not billed again on their own.
Medicare's coding rules list pairs of codes that usually shouldn't be billed together. A bundled payment works the same way on a bigger scale. A single payment covers a whole stretch of care, like a hip replacement and the 30 days after you leave the hospital.
On your explanation of benefits (EOB), a line marked as "included in another service" was likely bundled. If that same item shows up as an extra charge on your bill, ask the billing office to explain it. See common medical billing errors for how to check.
