What 78075 covers

This nuclear medicine study images adrenal cortical tissue, medullary tissue, or both after administration of an appropriate radiopharmaceutical. It may be used in evaluating selected adrenal lesions or suspected hormone-producing disorders, including suspected pheochromocytoma. A nuclear medicine physician or radiologist interprets the acquired images; the technical work includes the equipment and staff needed to perform the study. The exact tracer and imaging protocol depend on the tissue and clinical question being evaluated.

Select this code when the documented service is adrenal imaging, rather than imaging of the thyroid or parathyroid glands. The report should identify the clinical indication, the adrenal tissue evaluated, the study performed, and the interpreting findings. CMS recognizes a professional component for interpretation and a technical component for equipment and staff: report modifier 26 for the professional work, modifier TC for the technical work, or no component modifier when billing 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.

How to choose

78070Parathyroid imaging
This code describes parathyroid planar imaging. Use 78075 when the imaged tissue is adrenal, not parathyroid.
78071Parathyroid imaging
This code is for parathyroid imaging with subtraction techniques. It does not describe adrenal cortex or medulla imaging.
78072Parathyroid imaging
This code describes parathyroid imaging with SPECT and CT. Choose 78075 for an adrenal study, regardless of the difference in target gland.
78099Unlisted endocrine px dx nuc
This unlisted endocrine nuclear medicine code is a fallback when no specific code describes the study. Use 78075 when the service is adrenal imaging covered by its description.

78075 billing questions

How is this code distinguished from parathyroid imaging codes 78070–78072?

Code 78075 is for imaging adrenal cortical or medullary tissue. Codes 78070–78072 describe parathyroid imaging, so select based on the gland actually imaged.

Which modifiers identify the professional and technical portions?

Append modifier 26 for the professional interpretation or modifier TC for the technical service. Billing without either modifier represents the global service.

What documentation supports reporting adrenal imaging?

Document the adrenal indication, the tissue or clinical question evaluated, the imaging performed, and the interpreting findings. The record should support that the study concerns adrenal tissue rather than another endocrine gland.

Can both the professional and technical portions be billed separately?

The CMS component rules identify separately priced professional and technical portions. Report 26 for interpretation and TC for equipment and staff when those portions are billed separately; use neither for the global service.

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.
