What 77084 covers
This study uses magnetic resonance imaging to assess blood supply to bone marrow. It is selected when the ordering clinician specifically needs information about marrow perfusion, rather than a general anatomic MRI or a measurement of bone mineral density. A radiologist interprets the images; the technical portion involves the MRI equipment and staff. It may be performed in hospital or outpatient imaging settings.
Report 77084 when the performed study is directed at evaluating marrow blood supply and the record supports that purpose. The order and imaging report should identify the clinical question and the findings relevant to marrow perfusion. CMS recognizes a professional component for interpretation, reportable with modifier 26, and a technical component for equipment and staff, reportable with modifier TC. Billing without either modifier represents the global service, including both components.

How to choose
- 72195Pelvic MRI
- 72195 describes MRI of the pelvis for anatomic evaluation. Choose 77084 when the requested and performed study specifically assesses bone marrow blood supply.
- 77080DXA bone density scan
- 77080 is axial bone-density testing by DXA. It measures bone mineral density, not marrow perfusion.
- 77085DXA bone density
- 77085 is axial DXA with vertebral fracture assessment. It evaluates bone density and vertebral fracture status, not blood supply to marrow.
77084 billing questions
When should 77084 be chosen instead of a standard regional MRI?
Use 77084 for a study specifically assessing bone marrow blood supply. A regional MRI code describes an anatomic MRI examination, not this dedicated perfusion focus.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the professional interpretation and report, or modifier TC for the technical service. Without either modifier, the claim represents the global service.
What documentation supports reporting 77084?
The order and report should establish that evaluation of bone marrow blood supply was the purpose of the MRI, with findings addressing that question.
Is 77084 a bone-density study?
No. It evaluates marrow blood supply by MRI; bone-density codes measure bone mineral density using a different test.
Does a routine MRI that includes bone marrow qualify?
Not solely because marrow appears in the images. The study must be focused on assessing marrow blood supply, as shown by the order and report.
