What 78012 covers
This nuclear medicine test measures how much administered radiotracer the thyroid concentrates, using one or more measurements rather than producing a diagnostic thyroid image. It is commonly part of an evaluation of abnormal thyroid function, such as determining whether hyperthyroidism is associated with increased or decreased gland uptake. A nuclear medicine technologist performs the tracer handling and measurement; a qualified physician interprets the results. The service is performed in a nuclear medicine department or other equipped outpatient setting.
Report 78012 when the service consists of thyroid uptake measurement, not a combined uptake-and-imaging study. Documentation should identify the tracer and record the measurement or measurements and the physician’s interpretation. When thyroid imaging is also performed with uptake measurements, 78014 describes the combined service; do not separately report 78012 for the uptake portion included in that study. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.

How to choose
- 78014Thyroid scanQuantitative uptake measurement
- 78012 reports uptake measurement alone; 78014 describes thyroid imaging performed with uptake measurements.
- 78013Thyroid imagingWith blood-flow imaging
- 78013 is for thyroid imaging without the uptake measurement service reported by 78012.
- 78020Thyroid uptakeWhole-body metastasis measurement
- 78020 concerns uptake in thyroid carcinoma metastases, while 78012 measures uptake by the thyroid gland.
78012 billing questions
How do I choose between 78012 and 78014?
Use 78012 for uptake measurement without thyroid imaging. Use 78014 when the service includes thyroid imaging along with uptake measurements.
Can 78012 be reported with 78014 for the same study?
No. The uptake measurements are part of the combined service described by 78014, so reporting 78012 separately would duplicate that portion.
Which modifiers identify the professional and technical portions?
Modifier 26 reports the physician’s interpretation, while modifier TC reports the technical service. Reporting without either modifier represents the global service.
Does the number of uptake measurements change the code?
78012 covers a single measurement or multiple measurements. Document the measurement or measurements performed and the interpretation.
What documentation supports 78012?
The record should identify the administered tracer, document the thyroid uptake measurement or measurements, and include the interpreting physician’s findings.
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.
