CPT code 72146 refers to an MRI scan taken of the middle section of the spine without using any dye for more detailed images. CPT 72146 represents “Magnetic resonance (eg, proton) imaging, spinal canal and contents, thoracic; without contrast material.”
Procedure Explanation:
This code is used when doctors perform an MRI scan, a type of imaging test, to look at the spinal area in the chest or upper back region. In this test, no special dye is injected into the body, which is often done to enhance certain areas on the images. This type of MRI focuses only on the thoracic section of the spine, specifically looking for any issues in the spinal canal and its contents.
Common Names:
- MRI Thoracic Spine
- Spinal MRI Thoracic
- MRI T-Spine without Contrast
Relative Value Units (RVU):
The RVUs associated with this code are 1.48.
How This Procedure Appears:
- Operating Room Schedule Name: MRI Thoracic Spine without contrast
- Surgical Consent Form Name: MRI scan of the thoracic spine without dye
Typical Patients and Diagnoses:
This procedure is commonly used for patients who might be experiencing back pain, have had an injury, or have symptoms suggesting nerve problems in their upper back. For instance, someone with persistent back pain or a history of spinal injuries might need this test to see if there is any damage or abnormalities.
Associated ICD-10 Codes:
- M54.5: This code is for lower back pain, which may require imaging of nearby areas for a complete assessment.
- S23.3: Represents an injury to a thoracic spine nerve root, which might be scanned to evaluate injury extent.
- M51.16: Indicates intervertebral disc disorders with radiculopathy in the thoracic region, often needed to check for disc-related issues.
Summary
In summary, code 72146 describes an MRI scan of the upper back without the use of contrast dye. Typical ICD-10 codes associated with 72146 include M54.5 (lower back pain) and S23.3 (thoracic spine injury).
