CPT code for CathWorks’ 3D FFRangio wire free system

FFRangio demo

CathWorks has received a new CPT code 0523T for its non-invasive, 3D FFRangio system, which is designed to assess atherosclerotic stenoses during coronary angiography interventions. A press release reports that the code issuance is a major step forward in helping physicians objectively and cost-effectively determine if percutaneous coronary intervention (PCI) is indicated in every coronary angiography procedure.

The CathWorks FFRangio system is a non-invasive fractional flow reserve (FFR) platform that aims to quickly and precisely delivers objective multivessel physiologic measurements to cost-effectively optimize and confirm intraprocedural PCI therapy decisions.

CPT code 0523T enables healthcare providers using the CathWorks FFRangio system to be reimbursed for: intraprocedural coronary FFR with 3D functional mapping of colour-coded FFR values for the entire coronary tree, derived from coronary angiogram data, that allow real-time review and interpretation of possible atherosclerotic stenosis(es) intervention.

CathWorks CEO Jim Corbett says: “CPT code 0523T approval is a very important step for our company and the market. The CPT code decision also reflects the long-term clinical importance of objective FFR-based PCI decision-making. Creating a long-term reimbursement solution to support intraprocedural FFRangio will enable physicians, patients, and payers to realize the proven clinical and economic benefits of FFR on an every-case basis.”

The CathWorks FFRangio system is in development and is not yet FDA cleared.


  1. When this FFRangio system is used to do the FFR and 3D mapping, do any wires get inserted or is this wo the use of wires?
    Can you provide me with an example of how the procedure report would read.
    Thank you
