What A9502 covers
Technetium-99m tetrofosmin is a radioactive imaging agent administered intravenously for myocardial perfusion studies, commonly used to evaluate blood flow to the heart muscle at rest or with stress. Nuclear medicine departments and imaging centers furnish or administer the agent as part of the imaging encounter.
A9502 represents one diagnostic study dose, not a specified number of millicuries. Medicare assigns this code physician fee schedule status C, or carrier priced: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The HCPCS pricing method is other contractor pricing, and coverage is left to the contractor’s judgment. The imaging service, such as SPECT myocardial perfusion imaging, is represented by its own procedure code.

How to choose
- A9500Tc-99m sestamibiPer study dose
- A9500 is for technetium-99m sestamibi; A9502 is for technetium-99m tetrofosmin. Choose according to the tracer furnished.
- A9505Thallium-201Per millicurie
- A9505 identifies thallium-201 rather than tetrofosmin. Both are radiopharmaceutical codes used in myocardial perfusion imaging.
- A9526Nitrogen-13 ammoniaPer study dose, up to 40 mCi
- A9526 identifies nitrogen-13 ammonia for PET imaging, while A9502 identifies tetrofosmin used for myocardial perfusion imaging.
- 78452Nuclear stress testSPECT, multiple perfusion studies
- 78452 represents a multiple-study SPECT myocardial perfusion imaging service; A9502 identifies the tetrofosmin dose used for imaging.
A9502 billing questions
When should A9502 be used instead of A9500?
A9502 identifies technetium-99m tetrofosmin. A9500 identifies technetium-99m sestamibi; select the code matching the radiopharmaceutical furnished.
What does one unit of A9502 represent?
One unit represents one diagnostic study dose. The code is not based on a stated millicurie increment.
Is A9502 the code for the myocardial perfusion scan itself?
No. A9502 identifies the radiopharmaceutical dose. The imaging procedure, such as SPECT myocardial perfusion imaging, has a separate procedure code.
How does Medicare price and cover A9502?
A9502 has physician fee schedule status C, so there is no national payment amount; the Medicare Administrative Contractor sets payment for each claim. Coverage is also left to the contractor’s judgment.
What should the dose record support?
The record should identify the tetrofosmin dose furnished for the diagnostic study and support the units billed. Report the code for the radiopharmaceutical actually supplied.
