About CP191ZZ

CP191ZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the left upper extremity using a technetium 99m (tc-99m) 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 bone scan, the ICD-9-CM procedure title it maps to (92.14).

For a different body part, codes include CP111ZZ (skull), CP141ZZ (thorax), CP151ZZ (spine), CP161ZZ (pelvis), CP171ZZ (spine and pelvis), CP181ZZ (right upper extremity) and 5 more.

The same procedure with a different approach is coded CP19YZZ (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.
