About CD271ZZ
CD271ZZ is the ICD-10-PCS code for a tomographic (tomo) nuclear medicine imaging procedure on the gastrointestinal tract using a technetium 99m (tc-99m) 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 gastrointestinal scan and radioisotope function study, the ICD-9-CM procedure title it maps to (92.04).
The same procedure with a different approach is coded CD27DZZ (indium 111 (in-111)) and CD27YZZ (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.
