What 74183 covers

This code describes an MRI examination of the abdomen with images acquired both before and after contrast administration. A radiologist interprets the images; the technical work uses the MRI scanner, staff, and related equipment. Common clinical questions include characterizing a liver lesion, evaluating a pancreatic or adrenal abnormality, and assessing other abdominal organ findings. The examination is performed in hospital imaging departments and freestanding diagnostic imaging centers.

Choose this code when the documented abdominal study includes both noncontrast and postcontrast imaging, rather than only one contrast approach. The order and report should support the abdominal anatomy examined, the use of contrast, and the diagnostic interpretation. CMS recognizes separate professional and technical components: modifier 26 identifies interpretation, modifier TC identifies the technical service, and billing without either modifier represents the global service. When multiple diagnostic imaging procedures are reported, the CMS multiple-procedure reduction applies to both components.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

74183 billing questions

How does this differ from 74181 and 74182?

74183 represents an abdominal MRI with imaging both before and after contrast. Use 74181 for a study without contrast and 74182 for a study with contrast only.

Is the contrast reported as a separate MRI service?

No. The contrast phases are part of the MRI service represented by 74183; they do not make the examination two separate MRI studies.

When should modifier 26 or TC be used?

Use modifier 26 for the professional interpretation and modifier TC for the technical service. Without either modifier, the claim represents the global service.

Does the imaging multiple-procedure reduction affect this code?

Yes. CMS applies the diagnostic imaging multiple-procedure reduction to both the professional and technical components when the rule applies.

Can this code be used for an abdominal and pelvic MRI?

No. Code 74183 is for the abdomen. The reported anatomy and examination must support an abdominal MRI rather than an abdomen-and-pelvis study.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
