About 78018: Whole-body thyroid metastasis imaging with additional views
Reports whole-body nuclear imaging with additional views to evaluate iodine-avid metastatic thyroid carcinoma, such as during staging or follow-up after thyroid cancer treatment.
This nuclear medicine study evaluates possible metastatic thyroid carcinoma throughout the body and includes imaging beyond the whole-body acquisition. It is commonly performed in nuclear medicine departments for patients with differentiated thyroid cancer, including after thyroidectomy when a clinician is assessing for iodine-avid disease. A nuclear medicine technologist acquires the images, and a qualified physician interprets them.
Report 78018 when the documented examination includes whole-body imaging and additional imaging; use the documented extent and acquisitions to distinguish it from limited-area or whole-body-only studies. The record should support the thyroid cancer indication, the imaging performed, and the physician’s interpretation. Medicare recognizes professional and technical components: report modifier 26 for the interpretation, modifier TC for equipment and staff, or no component modifier for the global service.
CMS billing rules for 78018

78018 billing questions
How does 78018 differ from 78016?
78018 describes whole-body imaging with additional imaging. 78016 is the whole-body metastasis imaging option without that additional imaging distinction.
When should 78015 be used instead?
Use 78015 for thyroid carcinoma metastasis imaging limited to an area rather than a whole-body examination.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the physician’s interpretation or modifier TC for the technical service; without either modifier, the claim represents the global service.
What documentation supports 78018?
Document the thyroid carcinoma indication, the whole-body acquisition, the additional imaging performed, and the interpreting physician’s findings.
Is 78018 the right code for uptake measurement alone?
No. 78018 reports metastasis imaging with whole-body and additional imaging; 78020 is the related uptake-only option.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
