The TriNav® Infusion System is eligible for Medicare TPT reimbursement throughout 2023.

The CMS Transitional Pass-Through Payment (TPT) program facilitates Medicare patient access to new and innovative technologies.

The Centers for Medicare & Medicaid Services (CMS) TPT program facilitates Medicare patient access to new and innovative device technologies that have shown substantial clinical improvement over standard of care.

This important program allows for adequate payment of innovative products while CMS collects the data necessary to incorporate the cost of these technologies into permanent ambulatory payment classification (APC) outpatient payment rates.

As of January 1, 2020, the TriNav Infusion System is approved for TPT reimbursement.

After review of the TriNav application, supporting clinical data and favorable comments from the stakeholders, CMS determined that TriNav met the narrow program eligibility criteria, including demonstration of substantial clinical improvement compared to existing devices.1

Procedure Codes

To describe the use of TriNav, CMS created HCPCS Code C19821 (catheter, pressure-generating, one-way valve, intermittently occlusive). Pass-through codes should be used in conjunction with the procedure code(s) currently used by hospitals.

Medicare has stated that the device code describing TriNav should
always be billed with CPT Code 372422,3 or CPT Code 37243.2,3

37242 – Mapping (vascular embolization or occlusion, artery)

37243 – Treatment (vascular embolization or occlusion, organ)

CMS will make TPT payment when either code is appropriately reported in association with TriNav and TPT HCPCS Code C1982.3
