What 72146 covers
This service is an MRI examination of the thoracic, or mid-back, spine performed without contrast material. It may be used to evaluate symptoms or findings such as thoracic radiculopathy, spinal cord compression, or suspected disc, bone, or soft-tissue abnormality. Imaging centers and hospital radiology departments typically provide the technical service, while a radiologist interprets the images and issues a report.
Select this code when the documented study covers the thoracic spine and is performed without contrast; use the corresponding contrast or without-and-with-contrast code when that protocol is performed. The order and report should support the body region and contrast protocol. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and billing without either modifier represents the global service. When multiple diagnostic imaging procedures are performed, the multiple procedure reduction applies to both professional and technical components.

72146 billing questions
How does this differ from 72147?
This code is for a thoracic spine MRI performed without contrast. Code 72147 describes a thoracic spine MRI performed with contrast.
When should 72157 be reported instead?
Use 72157 when the thoracic MRI is performed both before and after contrast administration. The documented examination protocol determines the code.
Can the interpretation and imaging facility bill separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
How does the multiple procedure reduction affect this service?
When multiple diagnostic imaging procedures are performed, the CMS multiple procedure reduction applies to the professional and technical components.
What documentation supports this code?
The order and imaging report should identify the thoracic spine as the examined region and show that the MRI was performed without contrast.
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.
