CPT code 78491 refers to a specialized heart imaging test that uses a PET scan to see how well blood is flowing through the heart. This test might include looking at the heart’s movement or how well it pumps blood. CPT 78491 represents “Myocardial imaging, positron emission tomography (PET), perfusion study (including ventricular wall motion[s] and/or ejection fraction[s], when performed); single study, at rest or stress (exercise or pharmacologic).”
Procedure Explanation:
This procedure, known as a myocardial perfusion study, involves using a PET scan to assess blood flow in the heart either while the patient is at rest or under stress, which can be induced by exercise or medication. The test can also show how the heart muscle moves and how efficiently it pumps blood, though these components are optional and included only when needed.
Common Names:
- Heart PET Scan
- PET Myocardial Perfusion Imaging
- Cardiac PET Perfusion Test
Relative Value Units (RVU):
The RVUs associated with this code are 1.56.
How This Procedure Appears:
- Operating Room Schedule Name: PET Heart Perfusion Study
- Surgical Consent Form Name: PET Scan for Heart Blood Flow Assessment
Typical Patients and Diagnoses:
This test is commonly used for patients who may be experiencing symptoms like chest pain or shortness of breath, which could suggest heart disease. For example, it might be used to evaluate patients who have blockages in their coronary arteries or those who previously had a heart attack to see how their heart is performing.
Associated ICD-10 Codes:
- I25.10: This code signifies hardening of the coronary arteries due to plaque, but without mentioning chest pain.
- I20.9: This code is used when a patient has chest pain without a known cause.
- I21.9: This represents an unspecified heart attack, often used when detailed information isn’t available.
Summary
In summary, code 78491 describes a heart PET scan used to assess blood flow. Typical ICD-10 codes associated with 78491 include I25.10 (hardened arteries without chest pain) and I20.9 (unspecified chest pain).
