HCPCS Code C1725: Catheter, Transluminal Angioplasty, Non-laser (May include guidance, infusion/perfusion capability)

## **Documentation requirements** To bill HCPCS code C1725 correctly, documentation must clearly demonstrate medical necessity, appropriate device use, and procedural details consistent with CMS policies and coverage guidelines. Required documentation includes: - Procedure note confirming insertion and use of a non-laser transluminal angioplasty catheter during the intervention. - Clinical indications, such as peripheral vascular disease, vessel stenosis, or occlusion, support medical necessity for angioplasty. - Device identification, including manufacturer, model, and lot number, for traceability and compliance. - Notation of any guidance, infusion, or perfusion capability included in the device, when applicable. - Confirmation the device was opened and deployed during the procedure, as required by CMS for billing.

## **Billing requirements** **Unit of service**: Each — report one unit per catheter used during the procedure. ### **Coverage and payment setting:** - HCPCS code C1725 is recognized as the code for catheter transluminal angioplasty, non-laser, which may include guidance, infusion, or perfusion capability. - It is covered as a device under the hospital outpatient prospective payment system (OPPS) or ambulatory surgical center (ASC) payment system, as outlined by CMS. - In physician office settings, the cost of the device is bundled into the procedural service (e.g., angioplasty CPT codes) and not separately reimbursed. ### **Typical use:** - Hospitals and ASCs bill code C1725 for catheter transluminal procedures performed in peripheral vascular angioplasty cases, following CMS packaging and device reporting rules. - Documentation and claims should link the HCPCS code for catheter use to the corresponding CPT procedural code to ensure accurate device pass-through or packaged reimbursement.

## **Coding and modifier guidelines** HCPCS code C1725 should always be linked to the correct CPT interventional procedure code (e.g., 37220–37235 for peripheral angioplasty). To ensure correct coding and reimbursement: ### **Modifiers** - Use **-RT** or **-LT** modifiers to indicate laterality when applicable. - When multiple catheters are used in different vessels, report each catheter separately with appropriate units and document the medical necessity. ### **Bundling rules** Under OPPS, C1725 is typically packaged with the primary procedure code. ASC reimbursement for this device may vary, with some payers treating it as a device offset. ### **Claim notes** Include device manufacturer name, model, and lot number in claim remarks. Confirm the date of service matches related procedural claims.
