Radiology Question for the Week of May 6, 2024


A patient undergoes a PET scan with CT for attenuation correction and anatomic localization. Should the CT imaging be separately charged in this case when reporting 78433?


78433 does include CT for both attenuation correction and anatomic localization (i.e., fusion imaging). However, do not charge separately for diagnostic CT imaging unless a full and complete diagnostic CT scan (i.e., not just fusion imaging) is ordered and performed. If a full and complete diagnostic CT is separately ordered, medically necessary, and performed, assign the anatomic site-specific CT code, append the CT code with modifier 59, in addition to the appropriate PET imaging code.
