What 76978 covers
This service uses ultrasound with an injected microbubble contrast agent to assess a target lesion dynamically, including its perfusion pattern and contrast washout. It is commonly used to characterize indeterminate focal findings, such as a liver lesion, when contrast-enhanced ultrasound can provide information about vascular behavior. Imaging staff acquire the study, and a qualified physician interprets the findings and produces a report. It may be performed in a hospital or outpatient imaging setting.
Report 76978 for the first target lesion; code 76979 is used for each additional lesion when the service meets that code’s requirements. The record should identify the target lesion and document the dynamic contrast assessment and interpretation. The professional component may be reported with modifier 26, the technical component with modifier TC, or the global service without either modifier. The diagnostic imaging multiple procedure reduction applies to both the technical and professional components.

How to choose
- 76979Contrast ultrasoundEach additional target lesion
- 76978 is for the first target lesion; 76979 is for each additional lesion in the same dynamic microbubble contrast service.
- 76982Ultrasound elastographyFirst target lesion
- 76982 is targeted ultrasound elastography for a first lesion, assessing tissue stiffness rather than microbubble contrast perfusion and washout.
- 76942Ultrasound needle guidanceBiopsy, aspiration, injection, or localization
- 76942 reports ultrasound guidance for a needle procedure such as biopsy. 76978 reports dynamic contrast characterization of the lesion, not needle guidance.
76978 billing questions
When is 76978 reported instead of 76979?
Use 76978 for the first target lesion examined with dynamic microbubble contrast characterization. Use 76979 for each additional lesion when applicable.
Can the professional and technical services be billed separately?
Yes. Report modifier 26 for the interpretation and report, or modifier TC for equipment and staff. Without either modifier, the claim represents the global service.
Does the multiple procedure reduction affect both components?
Yes. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components.
Is this code for ultrasound-guided biopsy?
No. 76978 describes dynamic microbubble contrast characterization of a lesion, not imaging guidance for a needle biopsy. Code 76942 describes ultrasound guidance for biopsy.
What documentation supports reporting the service?
Document the target lesion, the dynamic contrast assessment, and the physician’s interpretation and report. Identify additional lesions separately when reporting 76979.
Are contrast-agent supplies included in 76978?
The CPT service describes the contrast-enhanced examination. If billing the contrast-agent supply separately, use the applicable HCPCS code for the agent administered and follow the relevant coverage and billing requirements.
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.
