Final answer:
The CPT coding reported for this coronary intervention with drug-eluting stent placement and IVUS interrogation would be 92928 for the stent placement and 92978 for the IVUS.
Step-by-step explanation:
The CPT (Current Procedural Terminology) coding that should be reported for the clinical summary described is as follows:
The correct CPT code for a percutaneous coronary intervention (PCI) with stent placement in the ostial/proximal segment of the right coronary artery is 92928. This code represents the procedure of coronary artery stenting including angioplasty, when necessary, for a patient who has a stenosis in a coronary artery. The CPT code for intravascular ultrasound (IVUS) is 92978, which is used when this imaging technique is performed in conjunction with PCI in the coronary arteries.
Therefore, for the professional component (the work done by the physician), the codes to be reported are 92928 for the stent placement and 92978 for the IVUS if the physician is billing separately for the imaging service provided during the intervention.
