MRI
Reports MRI-based measurement of tissue stiffness, most often to assess liver fibrosis in patients with chronic liver disease.
Magnetic resonance elastography uses MRI and externally generated vibrations to map how mechanical waves move through tissue and estimate its stiffness. It is most often performed to assess liver fibrosis in people with conditions such as chronic hepatitis or fatty liver disease, and can provide information that may help clinicians stage disease without a liver biopsy. The acquisition takes place in an MRI suite, with imaging staff performing the technical work and a radiologist interpreting the study.
Report the service for the elastography examination, supported by documentation of the clinical indication, body site, acquisition, and interpreted findings. When an abdominal MRI is also performed, the conventional MRI service may be separately reported when supported by the record and applicable coding guidance. Bill the global service without a component modifier, modifier 26 for the interpretation alone, or modifier TC for the technical service alone. CMS applies the diagnostic imaging multiple procedure reduction to both the professional and technical components when applicable.

Mr spectroscopy
76391 assesses tissue stiffness using MRI. Code 76390 is used for MR spectroscopy, which analyzes tissue chemistry.
74181 reports abdominal MRI without contrast for anatomic imaging. Code 76391 reports the elastography service that assesses tissue stiffness; both may be performed in one examination.
91200 reports liver transient elastography using a non-MRI technique. Choose 76391 when stiffness is assessed with MRI elastography.
76981 reports ultrasound elastography of parenchymal tissue. Code 76391 is the MRI-based method.

The office and facility calculations use their respective practice-expense RVUs. The facility amount here is the physician fee, not a separate hospital or facility bill.
Code 76391 reports MRI-based assessment of tissue stiffness. MR spectroscopy, reported with 76390, analyzes tissue chemistry rather than mechanical properties.
Yes, when a conventional abdominal MRI is also performed and separately supported. The elastography service measures tissue stiffness; the MRI provides anatomic imaging.
Use modifier 26 for the professional interpretation alone. Use modifier TC for the technical service alone, or report the global service without either modifier.
Yes. CMS applies the diagnostic imaging multiple procedure reduction to the professional and technical components when applicable.
Code 76391 uses MRI to map tissue stiffness. Code 91200 reports liver transient elastography using a different, non-MRI method.
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.
