2025 CPT code 93572
(Active) Effective Date: N/A Revision Date: N/A Cardiac Catheterization - Cardiovascular Procedures Medicine Feed
Intravascular Doppler velocity and/or pressure derived coronary flow reserve measurement during coronary angiography, including pharmacologically induced stress; each additional vessel.
Modifier -52 (reduced services) may be applicable if pharmacologic stress is not used (iFR).Other modifiers may be appropriate based on the circumstances of the procedure.
The medical necessity of the procedure must be documented, explaining the need to assess coronary flow reserve in the patient's particular case. This may include the presence of chest pain, abnormal stress tests, or other clinical findings suggesting coronary artery disease. The necessity for the additional vessel study (93572) should be explained.
The physician performs the cardiac catheterization, including the placement of the catheter and the administration of pharmacologic agents to induce stress. The physician interprets and reports the results of the Doppler study and pressure measurements.
In simple words: This code describes a test that measures blood flow in the heart's arteries during a heart catheterization.A medication is used to increase blood flow, and the test measures blood speed and pressure to find blockages in the arteries. This code is used for each additional artery tested after the first one.
This CPT code, 93572, reports the measurement of coronary flow reserve using intravascular Doppler velocity and/or pressure, performed during coronary angiography and involving pharmacologically induced stress. This code is specifically for each additional vessel beyond the initial vessel (reported with 93571). The procedure includes all necessary Doppler transducer manipulations and repositioning within the examined vessel during coronary angiography or interventional procedures (e.g., angioplasty).
Example 1: A patient undergoes coronary angiography.During the procedure, the cardiologist identifies blockages in the left anterior descending artery (LAD) and the circumflex artery.Code 93571 is used for the LAD (initial vessel), and code 93572 is used for the circumflex artery (additional vessel)., A patient with known coronary artery disease undergoes a coronary flow reserve study using intravascular ultrasound.The study shows a significant stenosis in the right coronary artery (RCA) and less significant stenosis in a diagonal branch of the LAD. 93571 is reported for the RCA, and 93572 is reported for the diagonal branch., A patient has a percutaneous coronary intervention (PCI) on the left circumflex artery. During the PCI, the cardiologist performs an intravascular Doppler velocity study to assess the flow reserve.A stenosis is also found in another vessel. 93571 is reported for the circumflex artery and 93572 for the additional vessel.
Detailed documentation is required, including the indication for the procedure, the vessels studied, the pharmacologic agent used (if any), the Doppler velocity and pressure measurements for each vessel, and the interpretation of the results.Radiologic images should be included.The report must justify medical necessity.
** Intravascular distal coronary blood flow velocity measurements include all Doppler transducer manipulations and repositioning within the specific vessel being examined.
