An expert group has been responsible for the ATC classification of radiopharmaceuticals in V09 and V10. The group has also prepared the guidelines for classification of these products.
Radiopharmaceuticals for diagnostic use are classified in this group, while radiopharmaceuticals for therapeutic use are classified in V10. In general, the 3rd level are subdivided according to site of action or organ system, the 4th level according to radionuclide and the 5th level specifies the chemical substance. The ATC 5th level defines the actual form essential in nuclear medicine procedures, which includes radionuclide and carrier molecule. Therefore, products on the market, that can often be regarded as intermediate products rather than ready-to-use radiopharmaceuticals, can be given more than one (5th level) ATC code, e.g. technetium (^99mTc) exametazime (V09AA01) and technetium (^99mTc) exametazime labelled cells (V09HA02).
ATC codes are not assigned for radionuclide precursors which are used only in the radiolabelling of another substance prior to administration.

This group comprises radiopharmaceuticals used for the imaging of liver, gall bladder, lymphatic system and bone marrow.

This group contains technetium colloidal and particle containing preparations for the scintigraphy of liver, spleen, lymphatic system and bone marrow. Also orally administered preparations used for gastrointestinal tract imaging (gastric emptying, reflux etc.) are classified in this group.


Preparations containing larger particles that are used for lung perfusion studies are classified in V09E - Respiratory system. Denatured labelled erythrocytes for spleen scintigraphy are classified in V09G - Cardiovascular system.
