About CP23YZZ

CP23YZZ is the ICD-10-PCS code for a tomographic (tomo) nuclear medicine imaging procedure on the skull and cervical spine using an other radionuclide 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 bone scan, the ICD-9-CM procedure title it maps to (92.14).

For a different body part, codes include CP21YZZ (skull), CP22YZZ (cervical spine), CP24YZZ (thorax), CP26YZZ (pelvis), CP27YZZ (spine and pelvis), CP28YZZ (right upper extremity) and 9 more.

The same procedure with a different approach is coded CP231ZZ (technetium 99m (tc-99m)).

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.
