What CPT® codes are reported for angioplasty of the diagonal branch with intravascular ultrasound?

The correct answer involves understanding the specific components of the CPT® coding system related to angioplasty procedures. In this context, when reporting codes for angioplasty of the diagonal branch, it is essential to use the appropriate codes that indicate the specific vessels treated and the additional procedures performed.

The code 92920 specifically refers to the percutaneous transluminal coronary angioplasty (PTCA) and is used to denote the procedure performed on the artery. The modifier "LD" indicates that the procedure is performed on the left diagonal branch, which is crucial for clarity in the medical billing process as it specifies the anatomical site.

Additionally, the code 92978 pertains to the use of intravascular ultrasound (IVUS) during the procedure and the modifier "26" is used to indicate that this service was a professional component, separate from technical components which may be billed by facilities.

Thus, the combination of 92920 with the modifier "LD" and 92978 with the modifier "26" accurately reflects both the angioplasty performed on the diagonal branch of the coronary artery and the use of intravascular ultrasound in its evaluation and treatment. This ensures that the coding aligns with the actual services rendered and the anatomical details involved, fully supporting the clinical decision-making
