CPT code 78075: Adrenal imaging, cortex or medulla2026 Medicare rate & RVUs

Medicare pays $387.45 for 78075 nationally in the office. Local office rates run $334.95–$547.39.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.

How to choose

78070Parathyroid imagingPlanar only

This code describes parathyroid planar imaging. Use 78075 when the imaged tissue is adrenal, not parathyroid.

78071Parathyroid imagingPlanar, with or without subtraction

This code is for parathyroid imaging with subtraction techniques. It does not describe adrenal cortex or medulla imaging.

78072Parathyroid imagingSPECT with CT

This code describes parathyroid imaging with SPECT and CT. Choose 78075 for an adrenal study, regardless of the difference in target gland.

78099Unlisted endocrine testNuclear medicine

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.

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.
