Vascular embolization or occlusion procedure using a pressure-generating device

This HCPCS code describes a vascular embolization or occlusion procedure that specifically involves the use of a pressure-generating device during the intervention. It captures the technical component of endovascular procedures where controlled mechanical pressure is applied to achieve vessel occlusion, distinguishing it from standard embolization techniques that rely solely on embolic agents or coils.

This code applies when a pressure-generating device is integral to the embolization or occlusion procedure, such as in certain arteriovenous malformation treatments, hemorrhage control, or tumor devascularization cases where pressure-assisted delivery is documented. Supporting documentation should include the operative/procedure report explicitly noting the use of a pressure-generating device, the target vessel(s), and the clinical indication. Verify that the device use is distinct from standard catheter-directed embolization to justify this code over conventional interventional radiology embolization codes.

• Avoid conflating with standard embolization CPT codes (e.g., 37241–37244); this HCPCS code is payer-specific and typically used in Medicare/Medicaid contexts where the pressure-generating device component requires separate identification.
• Documentation specificity is critical: the procedure note must explicitly reference the pressure-generating mechanism; generic embolization language will not support this code on audit.
• Check payer LCD/NCD policies before billing, as coverage and bundling rules for this code vary significantly by MAC; it may be bundled with facility or professional component charges depending on the payer contract and place of service.
