What 77081 covers
This service uses dual-energy X-ray absorptiometry to measure bone mineral density at an appendicular, or peripheral, skeletal site. A common example is measurement at the forearm. The test may be part of an osteoporosis evaluation when a peripheral measurement is needed; the acquisition is typically performed by radiology or bone-density staff, with interpretation by a physician or other qualified professional. The report should identify the site examined and include the findings and interpretation.
Report this code for the peripheral DXA study, not for central measurements of the spine or hip. The CMS physician fee schedule recognizes separate professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff service, and no modifier represents the global service. Documentation should support the appendicular site measured and the service actually furnished. The descriptor encompasses one or more peripheral sites as a single study.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose
- 77080DXA bone density scan
- Choose 77081 for an appendicular site such as the forearm; choose 77080 for central DXA measurements, such as the spine or hip.
- 77085DXA bone density
- 77085 combines axial DXA with vertebral fracture assessment. This code describes peripheral DXA and does not identify that axial fracture-assessment service.
- 77078CT bone density
- 77078 measures axial bone density using CT. This code is for DXA measurement at a peripheral skeletal site.
77081 billing questions
How does this differ from 77080?
This code is for DXA measurement at an appendicular, or peripheral, site. Code 77080 is for central DXA measurement, such as at the spine or hip.
Which modifiers identify the components?
Append modifier 26 for the professional interpretation or TC for the technical service, including equipment and staff. Report the global service without either modifier.
Can more than one peripheral site be included?
The service covers one or more appendicular sites. Document the site or sites measured; the code describes the study rather than a separate charge for each site.
What documentation supports reporting this code?
The record should identify the peripheral skeletal site measured and include the DXA findings and interpretation. The documentation should make clear that the study evaluated an appendicular site, not the spine or hip.
Should this code be used when vertebral fracture assessment is also performed?
Code 77085 describes axial DXA with vertebral fracture assessment. Use this code for a peripheral DXA study; the services should not be treated as interchangeable.
