What 78013 covers

A nuclear medicine study captures images of the thyroid and includes a blood-flow phase. It can help evaluate the distribution of functioning thyroid tissue, including suspected autonomous tissue or ectopic thyroid tissue. A nuclear medicine physician or radiologist typically interprets the images after acquisition with a gamma camera in a hospital or imaging center.

Report 78013 when the service includes thyroid imaging with blood-flow assessment but does not include quantitative thyroid uptake measurement. The record should support the clinical reason for imaging and document the performed imaging protocol and interpretation. CMS recognizes a professional component for interpretation, reported with modifier 26, and a technical component for equipment and staff, reported with modifier TC. Without either modifier, the claim 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.

78013 billing questions

How does 78013 differ from 78014?

78013 represents thyroid imaging with blood-flow assessment. Use 78014 when the imaging service also includes one or more quantitative thyroid uptake measurements.

When should 78012 be considered instead?

78012 is for quantitative thyroid uptake measurement without the thyroid imaging service represented by 78013. Choose based on the service actually performed and documented.

When are modifiers 26 and TC appropriate?

Use modifier 26 for the physician's interpretation and modifier TC for the technical service, including equipment and staff. Billing without either modifier represents the global service.

What documentation supports reporting 78013?

Document the clinical reason for the thyroid study, the imaging performed including its blood-flow phase, and the physician's interpretation. The record should distinguish imaging from any separately performed uptake measurement.

Is 78013 the code for thyroid cancer metastasis imaging?

No. 78013 describes thyroid imaging with blood-flow assessment; 78015 is for imaging directed at thyroid carcinoma metastases in a limited area.

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.
