About C050VZZ

C050VZZ is the ICD-10-PCS code for a nonimaging nuclear medicine probe procedure on the brain using a xenon 133 (xe-133) approach with none (qualifier: none). In ICD-10-PCS, nonimaging nuclear medicine probe means introduction of radioactive materials into the body for the study of distribution and fate of certain substances by the detection of radioactive emissions; or, alternatively, measurement of absorption of radioactive emissions from an external source.

In plain terms, this corresponds to other radioisotope function studies, the ICD-9-CM procedure title it maps to (92.09).

The same procedure with a different approach is coded C050YZZ (other radionuclide).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
