What 75577 covers
This service analyzes coronary CT angiography images to quantify atherosclerotic plaque burden and assess plaque characteristics in the coronary arteries. Image-processing software and trained staff support the analysis; a qualified physician interprets the results and documents the findings. It is used in cardiac imaging settings when a clinician seeks a detailed plaque assessment from coronary CTA data, rather than only a visual review of the angiogram or a coronary calcium score.
Report 75577 when the quantitative plaque analysis is performed and its findings are documented in a report. The record should support that coronary CTA data were analyzed and identify the resulting plaque findings. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, while modifier TC identifies the equipment and staff portion. Report the global service without either modifier when one billing entity provides both components.
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.

75577 billing questions
How is 75577 different from coronary CTA code 75574?
75574 represents coronary CT angiography; 75577 is the quantitative plaque analysis performed on coronary CTA data. The documentation should support each service reported.
Is 75577 a calcium score?
No. Code 75577 quantifies plaque using coronary CTA data, while 75571 reports a coronary calcium assessment from a noncontrast cardiac CT.
Can the professional and technical portions be billed separately?
Yes. Use modifier 26 for the professional interpretation and report, or modifier TC for the technical portion. Bill without either modifier for the global service.
What documentation supports 75577?
Document the coronary CTA data analyzed, the quantitative plaque findings, and the interpreting physician’s report. The record should show that a plaque analysis was performed, not only a standard CTA interpretation.
Does 75577 replace 75574?
No. The codes represent different services: coronary CTA and quantitative analysis of plaque using CTA data. Report both only when both services were performed and are supported by the record.
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.
