Educational Article: Percutaneous Coronary Intervention Therapeutic Drug-Delivery Balloons

CPT codes 0913T and 0914T describe percutaneous coronary revascularization services by intracoronary antiproliferative drug delivery for occlusive coronary disease using drug-delivery balloons. 0913T and 0914T are billed per specified vessel.

0913T includes accessing and selective catheterization of the vessel, coronary angiography and intracoronary imaging to guide the intervention, traversing the lesion, radiological supervision and interpretation directly related to the intervention, closure of arteriotomy and post-procedure imaging. This also includes any mechanical dilation by nondrug delivery balloon angioplasty followed by therapeutic drug-delivery balloon.

0913T can't be reported with CPT codes 92920, 92924, 92928, 92933, 92937, 92941, 92943, 92973, or 92978 for percutaneous coronary intervention on the same target lesion in the same artery or graft as the drug-delivery balloon.

If a drug-delivery balloon is performed in a separate target lesion in the same major coronary artery or graft, 0914T is used to identify the additional procedure.

0914T is an add-on code and includes only the coronary angiography and intracoronary imaging to guide the additional intervention, transversing the additional lesion, and radiological supervision and interpretation performed on the additional lesion.

0914T may be reported for the separate target lesion in conjunction with 92920, 92924, 92928, 92933, 92937, 92941, 92943, 92973, 92978. Since this is billed with the primary code, it's not eligible for separate payment.

There's no additional payment for 0913T or 0914T when billed with associated 929XX codes.

The 2026 AMA CPT Manual (pages 1158-1159) summarizes the coding rules for this service.
