What 74182 covers
This service covers MRI imaging of the abdomen after contrast administration, commonly with an IV gadolinium-based agent when clinically appropriate. It may be used to assess findings involving abdominal organs such as the liver, pancreas, kidneys, spleen, or adrenal glands. A radiologist interprets the images; imaging-center or hospital staff provide the technical service using the MRI equipment.
Select this code when the examination uses contrast without both precontrast and postcontrast imaging; an exam performed both before and after contrast is reported with the corresponding with-and-without-contrast code. The order and report should identify the abdominal examination, the clinical indication, and the contrast protocol performed. Bill without a modifier for the global service, or use modifier 26 for interpretation or TC for equipment and staff when billing a separately priced component. When multiple diagnostic imaging procedures are performed, CMS applies the multiple procedure reduction to both the professional and technical components.

74182 billing questions
When is 74182 used instead of 74183?
Use 74182 when the abdominal MRI is performed with contrast only. Use 74183 when the exam includes imaging both before and after contrast.
Can the interpretation and technical service be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the code represents the global service.
Does the multiple procedure reduction affect both components?
Yes. CMS applies the diagnostic imaging multiple procedure reduction to both the professional and technical components.
What documentation supports this code?
The record should support an abdominal MRI, the clinical reason for imaging, and the contrast protocol actually performed. The radiology report should document the examination and its findings.
How does this differ from an abdominal MRI without contrast?
Code 74182 represents an abdominal MRI with contrast only. Code 74181 is for an abdominal MRI performed without contrast.
