C-codes are HCPCS Level II codes that exist only inside Medicare's hospital outpatient payment system (OPPS). Most are device codes, and most of those are packaged: paid, but never priced or itemized on their own. A packaged C-code never appears as its own paid line in any public Medicare file: the procedure is visible, the device is not. This page explains how the payment actually works, and links the 25 device C-codes we cover.
The hospital reports the device code on its claim, but Medicare pays nothing for it separately. The device's cost is bundled into the APC payment for the procedure it was used in. No APC of its own, no rate, no line item. If you're hunting for a "C-code fee schedule rate" for a packaged code, there isn't one, and anything quoting a dollar figure for it is misreading the file.
Genuinely new device categories get transitional pass-through status: hospitals are paid separately, on a device pass-through APC, at amounts derived from hospital cost data. It's temporary by design, usually a few years, and when it lapses the code joins the packaged class. A handful of codes (brachytherapy sources, for instance) keep their own per-source OPPS rates.
Medicare's public claims data is built from professional claims and APC-grain facility summaries. A device code that's packaged into a procedure's payment never surfaces as its own paid line, so no public dataset can rank C-code billers, for any C-code, at any grain. Per-claim detail exists only in restricted CMS research files that can't be used in a commercial product. The honest playbook is the one reps already run: follow the procedures the device rides with. Every code page below maps them.
