C1601: reimbursement & related procedures.

C1601 is the HCPCS Level II device code (often searched as CPT C1601) for: Endoscope, single-use (i.e. disposable), pulmonary, imaging/illumination device (insertable). No public Medicare dataset shows who bills C1601: this class of device code never appears as its own paid line in Medicare's public claims files.

The reimbursement

What does Medicare pay for C1601?

C1601 is a transitional pass-through device (OPPS status indicator H) on device pass-through APC 2042: hospitals are paid separately for it, at amounts set from hospital cost data rather than a single national rate printed in Addendum B. Pass-through status is temporary by design; when it lapses, the code becomes packaged. In ambulatory surgical centers it is an OPPS pass-through device: paid separately, contractor-priced.

The honest answer

Why nobody can show you who bills C1601.

No public CMS dataset carries C1601 utilization, at any grain. It is paid separately to hospitals as a pass-through device, but those payments live in facility claims that CMS publishes only at APC grain, so the code still never appears as its own line in any public file. The Medicare-visible side is the procedure, not the device.

Per-claim C-code detail exists only in restricted CMS research files that can't be used in a commercial product. So any site offering a "C1601 top billers" list is showing you something other than real data. We'd rather show you what actually exists: the procedures below are where this device shows up in Medicare's public data, and each one has a real who-bills answer.

Where this comes from. Payment status is CMS's own 2026 OPPS Addendum B and ASC addenda, labeled with the file year; codes with no separate payment render CMS's status in words, never a fake $0. Device-procedure pairings come from CMS's published pairings for pass-through devices plus the procedure codes each device class is documented to ride with. Related-procedure counts come from CMS's public Medicare Provider Utilization & Payment data for 2024 (traditional fee-for-service only; lines under 11 beneficiaries are suppressed by CMS before publication). No public CMS file carries per-code utilization for these device codes at any grain, and these pages say so instead of inventing it. Code descriptions are CMS's own HCPCS Level II text. Prospect 811 organizes public data; it doesn't add to or alter it. Not affiliated with or endorsed by CMS. Full detail on the data page.
