Cardiac CT analysis
About 75580: Coronary CTA-derived flow analysis
Reports computational analysis of coronary CT angiography data to estimate lesion-related blood-flow limitation and help assess the functional significance of coronary disease.
This service uses computational processing of a coronary CT angiography dataset to estimate fractional flow reserve along the coronary arteries. The resulting analysis helps clinicians assess whether a narrowing seen on CT is likely to limit blood flow, without measuring pressure through an invasive coronary catheter. A cardiologist or radiologist typically interprets the analysis and prepares the report; the data processing may involve specialized software and technical staff.
Report 75580 for the completed CT-derived flow analysis, supported by the source CCTA study and a report identifying the findings and vessels evaluated. The CCTA acquisition is a distinct service represented by its own code when performed. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and billing without either modifier represents the global service.
CMS billing rules for 75580
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

75580 billing questions
How is 75580 different from coronary CT angiography?
CCTA provides the coronary images; 75580 reports computational flow analysis derived from those images. The acquisition and analysis describe different services.
Can 75580 be billed with modifier 26 or TC?
Yes. CMS separately prices modifier 26 for the professional interpretation and modifier TC for the technical service; billing without a modifier represents the global service.
What documentation supports 75580?
Keep the source CCTA information and the analysis report, including the estimated flow findings and the coronary vessels assessed.
Is 75580 reported once for each coronary artery?
Do not determine units from the number of vessels mentioned. Report the completed analysis according to the applicable CPT unit instructions, with the report documenting the vessels assessed.
Does 75580 measure coronary plaque burden?
No. It estimates the functional effect of coronary narrowing. Code 75577 addresses quantitative or qualitative characterization of coronary plaque from CCTA data.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
