What 78305 covers
A bone scan uses an injected radiopharmaceutical and a gamma camera to assess skeletal uptake in several regions. A nuclear medicine technologist performs the acquisition, and a radiologist or other qualified physician interprets the images. Typical clinical questions include evaluation of multifocal bone pain, suspected skeletal metastases, or possible bone infection involving more than one area. The study may be performed in a hospital or outpatient imaging center.
Choose this code when the documented examination covers multiple skeletal areas but is not a whole-body bone study or a three-phase study. The report should identify the regions imaged and include the interpreting physician’s findings. CMS recognizes professional and technical components: report modifier 26 for the interpretation, modifier TC for equipment and staff, or neither modifier when billing the global service. The claim should reflect the component actually furnished by the billing entity.
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.

78305 billing questions
How is this code distinguished from a limited-area bone scan?
Use this code when the examination images multiple skeletal areas. A scan confined to a limited area is reported with 78300.
When should the whole-body bone imaging code be used instead?
Use 78306 when the study is a whole-body bone scan. This code describes imaging of multiple areas rather than the whole skeleton.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Billing without either modifier represents the global service.
Does a three-phase protocol use this code?
A three-phase bone imaging study is reported with 78315. Select the code that matches the documented imaging protocol, not simply the number of body regions.
What should the report document?
Document the skeletal areas examined and the physician’s interpretation. The report should support that multiple areas were imaged rather than a limited region or the whole body.
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.
