HCPCS code C1753 – Intravascular ultrasound catheter

Key takeaways

HCPCS code C1753 reports a single-use intravascular ultrasound (IVUS) catheter. Its official descriptor is Catheter, intravascular ultrasound.

Under OPPS, C1753 carries status indicator N, so its cost is packaged into the primary procedure’s payment and never paid as a separate line.

Hospitals still report C1753 with its charge, because device charges feed the cost data CMS uses to set future APC rates.

Pair C1753 with an IVUS add-on code: 92978 or 92979 for coronary vessels, 37252 or 37253 for non-coronary vessels.

Hospital outpatient departments report C1753 on the UB-04. ASCs bill Medicare on the CMS-1500 under the ASC payment system.

What is HCPCS code C1753?

HCPCS code C1753 is the Level II code for a single-use intravascular ultrasound (IVUS) catheter. The Centers for Medicare & Medicaid Services (CMS) gives it the long descriptor Catheter, intravascular ultrasound. Hospitals report it when an IVUS catheter is used during a coronary or peripheral vascular procedure.

C1753 belongs to the C-code series, temporary HCPCS codes that CMS created for the Hospital Outpatient Prospective Payment System (OPPS). In the October 2026 OPPS Addendum B, C1753 carries status indicator N, which marks a packaged item. Its cost is packaged into the payment for the procedure it supports, so the catheter line is never paid on its own.

Key code attributes

• Code: C1753
• Long descriptor: Catheter, intravascular ultrasound
• Short descriptor: Cath, intravas ultrasound
• Code type: HCPCS Level II C-code (device category)
• OPPS status indicator: N, packaged and not separately paid (October 2026 Addendum B)
• Reporting setting: Hospital outpatient department, on the UB-04 (837I) institutional claim
• Maintained by: Centers for Medicare & Medicaid Services (CMS)

What procedure does C1753 support?

C1753 supports intravascular ultrasound (IVUS), a catheter-based imaging procedure that shows the inside of a blood vessel. The catheter is advanced to the target vessel. An ultrasound transducer at its tip produces cross-sectional images of the lumen, the plaque and the vessel wall.

Cardiologists use IVUS in the catheterization lab alongside coronary angioplasty and stent placement. Vascular teams use it in peripheral arteries and veins to size vessels and guide treatment. The catheter is single-use and discarded after the case. The ultrasound console and other reusable equipment are not reported with this code.

How OPPS treats C1753: Packaged, not paid separately

Under OPPS, status indicator N means a service is paid, but its payment is packaged into the payment for other services. There is no separate APC payment for the C1753 line. Medicare pays the hospital through the APC assigned to the primary procedure on the claim. Confirm the current status in the quarterly CMS OPPS Addendum B files.

The IVUS add-on codes are packaged too. In the October 2026 Addendum B, 92978, 92979, 37252 and 37253 all carry status indicator N as well. The coronary procedures they usually accompany, such as 92928 stent placement and 93458 catheterization, carry J1. That is a comprehensive APC, which folds nearly every service on the claim into one payment. The diagram below lays out how those lines sit on one coronary IVUS claim.

So why report C1753 at all? CMS sets future APC rates from the charges hospitals report on their claims. A catheter left off the claim makes IVUS cases look cheaper to CMS than they were. That logic is easy to miss if your team learned medical billing on fee schedule codes, where every line carries its own rate.

Key rules for C1753 under OPPS:

• Setting: Hospital outpatient departments report C1753 on the UB-04. Physicians do not report it on their professional claims.
• ASCs: Ambulatory surgery centers bill Medicare on the CMS-1500 (837P) and are paid under the ASC payment system. Check the ASC addenda for current device treatment instead of applying OPPS rules.
• No pass-through payment: C1753 does not carry pass-through status, so Medicare makes no separate device payment for it.
• NCCI edits: Edits change quarterly. Check the current hospital outpatient NCCI tables for the IVUS add-on code and its primary procedure.

What C1753 covers and what it excludes

Covered devices and procedures

• Single-use intravascular ultrasound catheters
• IVUS catheters used in coronary vessels or grafts and in non-coronary vessels
• IVUS catheters used during a diagnostic evaluation, angioplasty or stent placement

Excluded devices and situations

• Reusable imaging equipment: The ultrasound console is hospital equipment and takes no device code.
• Angioplasty and guiding catheters: Transluminal angioplasty catheters take C1725, and guiding catheters take C1887.
• Spinal catheters: Intradiscal catheters take C1754, and intraspinal catheters take C1755.
• OCT-only imaging: 92978 and 92979 also cover optical coherence tomography (OCT). An OCT catheter is not an ultrasound catheter, so C1753 does not describe it.
• Physician office procedures: C-codes are hospital outpatient codes, so an office claim carries no C1753 line.

CPT codes reported alongside C1753

C1753 sits on the same claim as the IVUS code that describes the imaging. All four IVUS codes are add-on codes (+), reported with a primary catheterization or intervention code. You can look up each primary procedure in our CPT code reference library. Check the quarterly NCCI tables before submitting, because edits change.

Coronary vs. non-coronary: Use 92978 and 92979 for coronary vessels and grafts. Use 37252 and 37253 for non-coronary vessels. The vessel imaged decides the code family, so take it from the procedure note.

Units: Report C1753 units to match the catheters actually opened and used. One catheter can image more than one vessel, so the additional-vessel codes do not by themselves mean another C1753 unit. Units keep the charge accurate but do not create separate Medicare payment.

C1753 vs. C1725, C1754 and C1755: Knowing which code to use

C1753 is often confused with nearby catheter codes. C1725 is the code most often swapped in, because its descriptor also names a vascular catheter. C1754 and C1755 sit in the same numeric block but describe spinal catheters.

Decision rule: If the catheter imaged a vessel with ultrasound, report C1753. If it dilated a vessel, look at C1725. If it sat in a disc or the spinal canal, look at C1754 or C1755. When in doubt, check the device label and the procedure note before you assign the code.

Documentation requirements for billing C1753

Most C1753 problems trace back to charge capture and documentation rather than coverage. Keep the elements below in the record before the claim goes out. A medical billing compliance checklist for device codes makes them routine.

1. Procedure note confirming IVUS catheter use: Name the IVUS catheter, the vessels imaged and the findings. Vague phrasing such as “catheter-based imaging performed” will not hold up in an audit.
2. Device label or invoice: Record the catheter model and lot number. It supports the charge on the claim and the cost data behind it.
3. Physician order and diagnosis: Keep a signed order for the procedure. Link it to an ICD-10-CM code that supports the imaging, such as coronary artery disease or peripheral artery stenosis.
4. Hospital claim with the correct revenue code: A hospital outpatient department reports C1753 on the UB-04, with a revenue code its MAC accepts, commonly 0272. A missing or invalid revenue code gets the line returned.
5. Units: Report one unit per catheter actually used, and document the count in the procedure note.

Commercial payers: Some commercial contracts pay device lines separately or carve out high-cost supplies. Others follow Medicare packaging. Check each contract and any invoice requirement before the first submission.

Medicare reimbursement for C1753

Medicare makes no separate payment for C1753 under OPPS. The catheter’s cost is packaged into the APC payment for the primary procedure on the claim. Here is what that means in practice:

• Where to check status: Look up C1753 in the quarterly CMS OPPS Addendum B files, and use Addendum D1 for the status indicator definitions. The Physician Fee Schedule does not price C-codes.
• Expected remittance: A C1753 line on a Medicare remittance usually shows no payment, often with group code CO and reason code 97. That is packaging working as designed, so there is no error to appeal.
• Cost sharing: The catheter carries no separate payment, so it carries no separate coinsurance. The patient’s cost sharing follows the primary procedure.
• Commercial payers: Commercial rates are set by contract and are not governed by OPPS. Ask each payer whether device lines pay separately.

Prior authorization and payer requirements

Prior authorization (PA) for C1753 follows the procedure rather than the device code. Payers that require PA attach it to the primary procedure and the IVUS service, not to the C1753 line.

Practical note: When a PA denial arrives, check whether it targets the primary procedure or the IVUS service. A zero-paid C1753 line on its own usually reflects packaging, not a coverage decision. Fix authorization problems at the procedure level, where payers make the decision.

Why C1753 claim lines get denied and how to fix them

Most C1753 line problems fall into a few patterns. Effective denial management starts with telling expected packaging apart from errors you can fix.

Keeping C1753 billing accurate over time

C1753 billing depends on two inputs that change on a schedule. CMS updates OPPS status indicators in the annual final rule and the quarterly addenda. NCCI edits change every quarter.

Build both checks into your billing calendar. When the OPPS final rule publishes each November, confirm the status indicator for C1753 and the IVUS add-on codes. When quarterly NCCI tables release, recheck the code pairs your team reports. Teams with strong revenue cycle management schedule these device-code reviews alongside every quarterly update.

For descriptor changes, check the quarterly HCPCS release on the CMS HCPCS overview.

How Pabau supports IVUS procedure documentation

The C1753 line belongs to the hospital’s facility claim, built in the hospital’s own billing system. The cardiology or vascular practice behind the case still holds much of the evidence. That includes the procedure note, the vessels imaged and the signed consent.

Pabau, the practice management platform we build for private practices, holds those records on one patient file. Treatment notes and digitally signed consent forms sit side by side. When a facility or payer asks for the case file, your team can send it without hunting through folders.

Pabau’s claims management tools cover the practice’s own professional claims. Pabau does not build hospital facility claims or assign device C-codes. Its job here is keeping the practice side of each IVUS case complete. Every subscription includes these tools, and structured onboarding fits them to your existing workflow.

Keep IVUS procedure records audit-ready

Pabau keeps procedure notes, signed consent forms and insurance claims on one patient record. Your team can send a complete case file whenever a facility or payer asks.

Conclusion

C1753 brings in no separate Medicare payment under OPPS, so a zero-paid catheter line is expected rather than a denial to fight. Reporting it still matters, because that charge feeds the cost data behind future APC rates.

The practical move is a chargemaster check. Map IVUS catheters to C1753, keep angioplasty catheters on C1725 and pair each C1753 line with its IVUS add-on code. Then recheck Addendum B every quarter.
