What 77078 covers

This service uses computed tomography and quantitative analysis to assess bone mineral density at one or more axial-skeleton sites, commonly the spine. It is used in osteoporosis evaluation and may be selected when spinal degenerative changes could complicate interpretation of a DXA measurement. A technologist typically acquires the images, and a qualified practitioner interprets the study and reports the findings in an imaging or outpatient setting.

Report 77078 for the CT bone-density study of the axial skeleton, not for DXA or a peripheral-site study. Documentation should identify the axial site examined, the CT-based measurement method, and the interpretation. CMS recognizes separate professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and billing without either modifier represents the global service.

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.

77078 billing questions

How does 77078 differ from 77080?

77078 is a CT-based bone-density study of the axial skeleton. 77080 reports axial bone-density measurement by DXA.

Which modifier identifies the interpretation?

Append modifier 26 for the professional interpretation. Modifier TC identifies the technical portion, including equipment and staff.

What does billing 77078 without a modifier represent?

An unmodified claim represents the global service, including both the technical and professional components.

What documentation supports reporting 77078?

The record should identify the axial site assessed, establish that the study used CT-based quantitative bone-density measurement, and include the interpreted findings.

Can 77078 be used for a peripheral bone-density site?

No. This code is for axial-skeleton assessment; 77081 is the DXA code for an appendicular-skeleton study.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
