The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on percutaneous radiofrequency catheter ablation for atrial fibrillation.

One of the following codes is assigned depending on the area of ablation:

K57.4 Percutaneous transluminal ablation of accessory pathway

K62.1 Percutaneous transluminal ablation of pulmonary vein to left atrium conducting system
K62.2 Percutaneous transluminal ablation of atrial wall for atrial flutter

K62.3 Percutaneous transluminal ablation of conducting system of heart for atrial flutter NEC

In addition to one of the above codes, the following code is assigned in addition: 

Y11.4 Radiofrequency controlled thermal destruction of  organ NOC

Note: The OPCS-4 codeY53.4 Approach to organ under fluoroscopic control is assigned in addition if fluoroscopic guidance is used.

If codes K57.4 or K62.3 are chosen, the site code Z33.6 Atrium of heart is assigned following Y11.4, or following Y53.4 if fluoroscopic control is used.

In addition the ICD-10 code I48.X Atrial fibrillation and flutter would be recorded.
