For a cardiovascular SPECT study performed without quantification, which CPT® code applies?

The correct choice is based on the specific procedures performed during a cardiovascular SPECT study that does not include quantification. CPT code 78451 specifically refers to a nuclear medicine study for the heart, specifically a single-day protocol for planar imaging and SPECT that does not involve quantification. This code is used when assessing the myocardial perfusion without any additional advanced measurements.

The other CPT codes mentioned either represent different types of procedures or include quantification elements, which are not applicable in this scenario where quantification is specifically excluded. For example, 78453 refers to a more comprehensive SPECT study that includes quantification, and 78472 pertains to advanced imaging techniques or additional procedures that would not apply to a standard non-quantified cardiovascular SPECT study.

Using 78451 accurately reflects the nature of the procedure being performed, ensuring appropriate coding and billing practices are followed in medical documentation. This is crucial for receiving the correct reimbursement for services rendered.
