CPT code 78452 is used to bill for 3D (three-dimensional) imaging of the heart by using a high-energy CT (Computed tomographic) scanner (SPECT).
A radioactive substance is incorporated by mouth or IV (Intravenous) to focus the heart function and blood flow by taking images. Radionucleotides, usually thallium or technetium-99m, are localized only in non-ischemic tissue.
These substances are injected through an IV route to the body of the patient to perform tomographic Cardiac perfusion imaging. SPECT (Single-photon emission computed Tomographic) scans of the heart are obtained to classify areas of perfusion vs. infarction.
SPECT usually has a single or multiple head camera that can easily rotate around the patient’s body which differs from typical planar imaging.
It gives a 3D scan of the heart to represent the heart in thin slices. When service is performed without stress, induction and images are obtained, known as the non-stress version.
CPT Code 78452 Intro
For multiple studies, CPT code 78452 will be billed that take images at rest or stress conditions by giving the second radionucleotide again in the redistribution and/or resting phase just before rest state to scan the rest imaging.
CPT 78451 and CPT code 78452 include attenuation correction (AC), which helps to obtain the most accurate diagnostic imaging for diagnosing defects or infarcted areas by enhancing the radioactivity distribution count at that particular area.
For example, If radioactivity count is lower at the anterior wall due to the presence of breast.
These codes also include ejection fraction (EF) quantitative and qualitative wall motion to cater to this problem by additional quantification and/or the first pass or gated technique.
CPT Code 78452 Description
When multiple studies are performed at rest and/or stress (exercise or pharmacologic), and/or rest injection and/or redistribution to perform 3D SPECT Myocardial perfusion imaging which also includes:
- Ejection fraction by gated technique or first pass
- Attenuation correction
- Additional quantification
- Qualitative and quantitative wall motion
There is the following list of modifiers that are applicable with CPT 78452:
The most frequent modifiers used with CPT 78452 are 22, 26, 52, 53, and TC.
Modifier 26 is applicable with CPT code 78452 when a physician is only giving professional services like in a hospital as an employee. The physician is doing supervision and interpretation of medical imaging.
Modifier TC (Technical component) is approp5riate to bill with facility claims. It designates the technical component used during medical imaging.
A global modifier is used when Physicians own the clinic or do services in a private office. The physician owns the Machinery or technical component.
In this scenario, a global modifier will be used, which means that without modifiers 26 and TC. It would be like 78452 only instead of 78452-26, 78452-TC.
Modifier 52 is applicable when the service is partially complete or reduced services. In CPT code 78452 scenario, It includes 3D imaging at rest and/or stress state.
The second radionucleotide was not given due to unavoidable circumstances like electricity issues or the patient’s condition. In this case, Modifier 52 will be attached with CPT 78452.
Modifier 53 is applicable with CPT 78452 when the procedure is terminated due to the patient’s conditions or other unavoidable circumstances.
For instance, When a physician starts the procedure or service, an IV radionuclide is injected into the patent’s body, and any allergic reaction starts against the substance. Patients’ conditions become critical, and they decide to terminate the procedure early.
Modifier 22 will be appended with CPT code 78452 when services get longer than normal.
CPT 78452 rate varies based on what modifier is attached, like Modifier 26, TC, or global Modifier. Only 1 unit can be billed for CPT 78452 on the same day.
Two units are allowed if medical documentation supports this service. The total RUVS and cost of CPT code 78452 are listed in the list below:
Facility – 15.5 (Global) – 2.40 (Modifier 26) – 13.0 (TC)
Non-Facility – 15.5 (Global) – 2.40 (Modifier 26) – 13.0 (TC)
Facility – 536.40$ (Global) – 83.36$ (Modifier 26) – 453.04$ (TC)
Non-Facility – 536.40$ (Global) – 83.36$ (Modifier 26) – 453.04$ (TC)
OPPS Global – 1647.65$ (Global) – 83.36$ (Modifier 26) – 1564.29$ (TC)
CPT Code 78452 Billing Guidelines
There are the following guidelines for CPT 78452:
Stress test CPT codes (93015-93018) should also be reported separately in combination with CPT 78452.
Some Payers or insurance does not cover the substance or contrast media. Therefore, Check with a specific payer to determine the coverage.
CPT 78451 and CPT code 78452 are not allowed to be billed together on the same day as per the National Correct Coding Initiative (NCCI), and the modifier is also not allowed.
Therefore, Only 1 CPT will be payable, usually with the higher amount, which is CPT 78452.
CPT 785452 does not include CPT Codes (78800 – 78804) and (78830 -78835), which should be separately reportable with the appropriate modifier.
A modifier is allowed to append with CPT (78800 – 78804) (78830 – 78835) as per NCCI.
In order to receive proper reimbursement, the ICD 10 codes play a significant role in the reimbursement of CPT codes.
CPT code 78452 only gets paid when heart-related ICD 10 codes are attached with claims according to their respective LCD/NCD.
The most common ICD codes that support the medical necessity of CPT Codes are I25.10, RO7.9, R06.02, and if the patient has a family history of heart disease should also be appropriate to code.
The following are examples of when it is appropriate to use CPT Code 78452:
