About 72133: Lumbar CT Before and After Contrast
Reports lumbar spine CT imaging acquired before and after contrast when both noncontrast and contrast-enhanced sequences are performed.
This service covers CT imaging of the lumbar spine both before and after contrast administration, with a radiologist interpreting the study. It may be ordered to assess lumbar findings such as suspected infection, a mass, or postoperative change when the requested examination includes both imaging protocols. Services may be performed in a hospital or outpatient imaging center equipped for CT.
Report this code when the documented examination includes both noncontrast and contrast-enhanced lumbar CT imaging; a single phase calls for the corresponding without-contrast or with-contrast code instead. The report should support the lumbar anatomy imaged and both portions of the examination. CMS allows billing globally, or separately for the professional interpretation with modifier 26 and the technical service with modifier TC. The diagnostic imaging multiple-procedure reduction applies to both professional and technical components when applicable.

72133 billing questions
When should this code be selected instead of 72131 or 72132?
Use this code when the lumbar CT includes imaging both before and after contrast. Use 72131 for a noncontrast study and 72132 for a study performed with contrast only.
Can 72131 and 72132 also be reported for the same examination?
Do not report those codes in addition to this code simply to represent the two phases of one combined examination. This code represents the lumbar CT performed both before and after contrast.
How are the professional and technical services billed?
Report the global service without a component modifier, or use modifier 26 for the professional interpretation and modifier TC for the technical service. CMS identifies both components as separately priced.
What documentation supports reporting the combined study?
The imaging report should identify the lumbar spine examination and document that both noncontrast and contrast-enhanced imaging were performed.
Can the multiple-procedure reduction affect either component?
Yes. CMS applies the diagnostic imaging multiple-procedure reduction to both the professional and technical components.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
