Advancing Reimbursement for AI-Assisted Quantitative MRI
Effective January 1, 2024, new Category III CPT codes (0865T, 0866T) are now in place for AI-assisted quantitative brain MRI analysis. These codes cover a range of vendor solutions and represent a critical milestone on the path toward permanent reimbursement.
To support broader clinical adoption and ensure long-term reimbursement, providers are encouraged to actively report these codes when appropriate. Increased usage is essential for advancing them beyond their temporary Category III designation.
Together, we can drive sustainable reimbursement for AI-powered quantitative MRI analysis and enhance patient access to these innovative technologies.
What These Codes Describe
0865T
This code is used for quantitative MRI analysis without a diagnostic MRI examination during the same session.
+0866T
This add-on code is to be used when quantitative MRI analysis is performed in the same session with a diagnostic MRI examination. It must be reported alongside primary MRI codes (70551, 70552, 70553).
Refer to these codes for:
Brain Volume Quantification and Lesion Analysis
Comparison to prior studies AI-Assisted Quantitative MRI Interpretation
Do not refer to these codes for:
For Tissue Composition Analysis (refer to 0648T, 0649T, 0697T, or 0698T)
For CT-Based Analysis (refer to 0721T or 0722T)
If No Comparison to Prior MRI (refer to modifier 52 with 0865T or 0866T)
