Key takeaways
HCPCS code C1887 reports a guiding catheter, and the descriptor allows for infusion or perfusion capability.
The code belongs on hospital outpatient and ambulatory surgical center facility claims, never on a physician office claim.
Medicare packages C1887 into the payment for the primary procedure, so the line rarely adds money on its own.
Most C1887 denials trace back to a missing CPT companion code or a procedure note that never names the catheter.
Practice management software like Pabau keeps procedure records and claim submission in one place, so billers work from the clinical note.
HCPCS code C1887 reports a guiding catheter, and the descriptor stretches to catheters that also carry infusion or perfusion capability. It’s a device code. That means it never travels alone on a claim.
The pairing is where most C1887 lines come unstuck. The catheter went in and the procedure went fine. Then the claim bounces, because the note never named the device or the CPT companion code never made it onto the bill.
So start with the descriptor itself, which covers more ground than most billers expect.
What C1887 covers, and what it doesn’t
C1887 covers a guiding catheter used in a hospital outpatient department or an ambulatory surgical center. The parenthetical in the descriptor, “may include infusion/perfusion capability”, is permissive rather than required. One code applies whether or not your catheter has that extra function.
C-codes sit inside HCPCS Level II, and CMS maintains them for facility device reporting. They don’t appear on physician office claims or Part B professional claims.
If your practice bills professional services only, C1887 will never reach your worklist. The CMS HCPCS overview sets out how the series is maintained.
Where a guiding catheter earns the code
A guiding catheter earns C1887 whenever it supports a separately billed procedure in one of those two settings. The catheter creates the path. Balloons, stents, wires and microcatheters all travel down it to reach the target vessel.
The code describes the device, not the work. The CPT code on the claim carries the procedure itself.
- Cardiac catheterization: the guiding catheter gives coronary access during diagnostic and interventional cath lab work
- Coronary angiography: it sits in the coronary ostium to deliver contrast and steer diagnostic wires
- Percutaneous coronary intervention: it supports stent delivery and balloon inflation during angioplasty
- Interventional radiology: peripheral vascular, renal artery and carotid work all rely on guiding catheters
- Neurointerventional procedures: larger-bore guiding catheters act as access conduits in stroke intervention
Nothing about the code is procedure-specific. Whatever the guiding catheter is doing, in a hospital outpatient department or an ASC, C1887 is the line that reports it.
What Medicare actually pays for C1887
Usually nothing extra. Medicare packages device C-codes into the Ambulatory Payment Classification, or APC, that pays for the primary procedure. The cost of the catheter already sits inside that payment.
C1887 did once carry device pass-through status, and that expired at the end of 2002. It has been a packaged line ever since. Anyone expecting a separate dollar amount against it is reading the wrong payment rule.
Why you still report a packaged code
Because CMS builds next year’s rates from this year’s claims. Every packaged C-code line feeds the cost data behind APC weights. Leave the device off and you understate what the procedure really costs your facility.
There’s a practical reason too. Payer audits compare the procedure note against the billed lines. A note describing a guiding catheter with no matching device line invites a question you don’t want.
Rates also move every year and vary by wage index, so no fixed figure belongs in an article like this one. The CMS hospital outpatient regulations page carries the current final rule and its addenda.
Modifiers that belong on a C1887 line
Fewer than you’d think. C1887 is a supply line, so most of the modifier work on a cath lab claim happens on the procedure codes around it. Check each payer’s facility billing guide before you attach anything.
That last row trips people up. CMS retired -FB and -FC on hospital outpatient claims on January 1, 2014. Device credits moved to value code FD, paired with condition code 49, 50 or 53. ASCs kept the modifiers, so the same credit gets reported two different ways depending on the setting.
Commercial payers and Medicaid managed care plans write their own rules here, and they don’t have to match Medicare. Keep each contract’s modifier requirements somewhere your billers can find them in seconds. A shared drive nobody opens doesn’t count.
Pro Tip
Pull the cath lab supply log for one busy day and set it next to the claims that went out. Count the guiding catheters opened, then count the C1887 units billed. If those two numbers don’t match, the problem sits upstream of billing, in how the device gets recorded during the case.
What your documentation has to prove
Two things. A guiding catheter was used, and it was used for the procedure you billed. Every item below serves one of those jobs.
Medical documentation workflows that capture device detail during the case keep the two connected. Device records also have to survive an audit years later.
- Procedure documentation: the note names the catheter, with type, size and manufacturer where the record allows
- Medical necessity: the record supports why a guiding catheter was needed for this particular procedure
- Device linkage: the catheter ties back to one patient and one encounter, usually through a supply log or invoice
- CPT pairing: C1887 rides alongside the CPT code for the primary procedure, and a standalone device line gets rejected
- Claim form: hospital outpatient departments report C1887 on the UB-04, while freestanding ASCs bill Medicare facility claims on the CMS-1500 or 837P
- Quantity: report one unit per catheter used, never a single unit standing in for three
Before you submit: A five-point check
Run this over any claim carrying a device line. It takes about a minute, and it catches most of what would otherwise come back.
- Does a CPT procedure code sit on the same claim?
- Does the note name the catheter, rather than just saying “catheter”?
- Does the unit count match the number of catheters actually opened?
- Is the claim on the right form for the setting, UB-04 or CMS-1500?
- Has anyone read this payer’s facility billing guide in the past year?
Mistakes that send C1887 back
Four turn up again and again.
A device line with no procedure. The CPT code got dropped, or it’s sitting in coding review while the rest of the claim goes out. That line will not process on its own.
One unit for three catheters. Cath lab teams often open more than one guiding catheter during a case. The claim has to say so, and the supply record has to back it up.
A note that just says “catheter”. Generic wording leaves the coder guessing between C1887 and a neighboring code. Guessing is how the wrong C-code lands on a claim.
The wrong form for the setting. An ASC claim built like a hospital outpatient claim comes back before anyone reads the codes. Storing device records centrally, with patient data security already handled, saves the scramble when an auditor asks for them.

Codes that travel with C1887
Guiding catheters sit in a wider family of cardiovascular device C-codes, and picking the wrong one is an easy mistake on a busy day. These are the codes that most often appear on the same claim.
Two more sit close by. C1876 covers a non-coated stent with its delivery system, and C1886 covers a catheter for extravascular tissue ablation.
Verify descriptors before you lean on any crosswalk. The AAPC HCPCS lookup is quick for a single code, and CMS reissues the HCPCS file on a quarterly update cycle.
Pro Tip
Build a one-page device matrix for your cath lab or IR suite. List each device you stock, its C-code, and the CPT codes it usually accompanies. Review it every January against the new OPPS Addendum B, before the first claim of the year goes out.
How practice management software keeps C1887 claims clean
Most C1887 problems start long before billing sees the claim. The catheter detail lives on a paper log in the lab. The note gets dictated later, and the biller rebuilds the device line from memory.
Pabau is an all-in-one practice management system, and the part that matters here is where the record sits. Digital intake and procedure forms capture device detail at the point of care. What the team recorded during the case is what the coder reads afterward. No retyping, no second log to reconcile.
From there, claims management handles the submission side. It checks the insurer fields on a claim before it goes out, then tracks what comes back. A rejection lands as a task on someone’s list, rather than a surprise at month end.
The same setup works well outside the cath lab. Teams in IV therapy practices and longevity practices wrestle with the same consumable records, even though C-codes stay in the hospital outpatient and ASC lanes.

Keep device detail and claims in one system
Pabau captures procedure and device detail on digital forms during the case, then carries it through to claim submission. Your billers work from the clinical record instead of a paper log.
Conclusion
C1887 is a small line on a big claim, and it behaves like one. On its own it adds no money. Left unsupported, it can still hold up everything else on the claim.
The fix is unglamorous. Capture the device detail while the case is still open. Keep the unit count honest, and send the claim on the form that setting actually uses. Do that consistently and the denial pile shrinks without anyone chasing it.
If your billing team is still rebuilding device lines from paper logs, that’s the part worth changing first. Book a demo to see how Pabau keeps procedure records and claim submission in one place for outpatient practices.

Frequently asked questions
Which revenue code goes with C1887 on a UB-04?
Medicare doesn’t mandate one. Most hospital chargemasters map guiding catheters to a supply revenue code, commonly 0272 for sterile supply. The mapping is a chargemaster decision, so confirm it against your MAC’s billing guide before anyone changes it.
Does C1887 need prior authorization?
No. Medicare’s outpatient prior authorization program applies to a defined list of service categories, and guiding catheters are not on it. Any authorization requirement follows the procedure code, not the device line.
Do commercial payers accept C-codes like C1887?
Not all of them. C-codes were built for Medicare facility reporting, so commercial contracts vary widely on whether the line is recognized, ignored or rejected. Check the payer’s facility billing guide before you assume it will process.
Is C1887 priced on the Medicare Physician Fee Schedule?
No. The Physician Fee Schedule prices professional services, and C1887 is a facility device line. Payment for it comes through OPPS or the ASC payment system, where it is normally packaged into the primary procedure.
