About CB129ZZ
CB129ZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the lungs and bronchi using a krypton (kr-81m) approach with none (qualifier: none). In ICD-10-PCS, planar nuclear medicine imaging means introduction of radioactive materials into the body for single plane display of images developed from the capture of radioactive emissions.
In plain terms, this corresponds to pulmonary scan, the ICD-9-CM procedure title it maps to (92.15).
The same procedure with a different approach is coded CB121ZZ (technetium 99m (tc-99m)), CB12TZZ (xenon 127 (xe-127)), CB12VZZ (xenon 133 (xe-133)) and CB12YZZ (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.
