What 75580 covers

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.

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 the 75580 rate is calculated

Each of 75580’s three RVUs is multiplied by a geographic index (GPCI) for the payment locality, added up, and multiplied by the conversion factor. Drag the indexes or enter a ZIP to see what moves the rate.

How to choose

75574Coronary CTAWith contrast and 3D reconstruction
75574 represents coronary CT angiography image acquisition and interpretation. Use 75580 for the additional computational estimate of flow based on CCTA data.
75577Coronary plaque analysisCTA-based quantification
75577 characterizes coronary plaque from CCTA data; 75580 estimates the functional effect of coronary narrowing on blood flow.
75571Calcium scoringQuantitative coronary calcium
75571 measures coronary calcium burden on noncontrast CT. It does not provide the lesion-specific flow estimate reported with 75580.

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 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.
