About CB229ZZ
CB229ZZ is the ICD-10-PCS code for a tomographic (tomo) nuclear medicine imaging procedure on the lungs and bronchi using a krypton (kr-81m) approach with none (qualifier: none). In ICD-10-PCS, tomographic (tomo) nuclear medicine imaging means introduction of radioactive materials into the body for three dimensional 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 CB221ZZ (technetium 99m (tc-99m)) and CB22YZZ (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.
