About the C22 Code Range
These procedures capture emissions from radioactive materials introduced into the body to create three-dimensional images of the heart.
The fourth character identifies the imaged part: the right and left heart, the myocardium (heart muscle), or the heart. The fifth character identifies technetium 99m, indium 111, fluorine 18, thallium 201, another radionuclide, or none. The sixth and seventh characters have only the None qualifier.
