What 77085 covers
This service combines DXA bone density measurement of the axial skeleton, such as the hips, pelvis, or spine, with evaluation for vertebral fractures. It is commonly performed in outpatient imaging centers and hospitals for patients being evaluated for osteoporosis or vertebral fracture risk. Imaging staff acquire the study, and a qualified interpreting professional reviews the bone density and fracture-assessment findings and prepares a report.
Report 77085 when the axial DXA study includes vertebral fracture assessment; the documentation should identify the sites examined and support both the bone-density study and its interpretation. The code may be billed globally, or the interpretation may be reported with modifier 26 and the equipment-and-staff portion with modifier TC. The record should make clear which portion the billing entity furnished when a component modifier is used.

How to choose
- 77080DXA bone density scanAxial skeleton, spine or hip
- Both describe axial DXA, but 77085 includes vertebral fracture assessment. Choose 77080 when that assessment is not part of the study.
- 77086Vertebral fracture assessmentDXA imaging only
- 77086 represents vertebral fracture assessment via DXA, while 77085 combines that assessment with axial bone-density measurement.
- 77081Bone densityAppendicular skeleton
- 77081 is for appendicular DXA, such as a forearm site; 77085 is for axial sites such as the hips, pelvis, or spine.
- 77078CT bone densityAxial skeleton
- 77078 uses CT to assess bone density. 77085 is the DXA service that includes axial bone-density measurement and vertebral fracture assessment.
77085 billing questions
When should 77085 be used instead of 77080?
Use 77085 when axial DXA is performed with vertebral fracture assessment. Use 77080 for axial DXA without that assessment.
Can 77086 also be reported for the same vertebral fracture assessment?
77085 includes vertebral fracture assessment with the axial DXA. Do not report 77086 again for that same included assessment.
How do modifiers 26 and TC apply?
Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical portion involving equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports reporting 77085?
Document the axial sites examined, the DXA findings, the vertebral fracture assessment, and the interpreting professional’s report.
Is a DXA of the forearm reported with 77085?
No. 77085 describes axial sites such as the hips, pelvis, or spine; appendicular DXA, such as a forearm study, is reported with 77081.
