What 76826 covers

Code 76826 represents a repeat or follow-up ultrasound examination focused on the fetal heart, using real-time two-dimensional imaging and M-mode when performed. A fetal cardiologist, maternal-fetal medicine specialist, or radiologist may perform or interpret the study in an office, hospital, or imaging setting. Typical reasons include reassessing a cardiac finding identified on an earlier fetal echocardiogram or completing a cardiac assessment that required follow-up.

Choose this code for a repeat or follow-up cardiac imaging study, rather than a complete fetal echocardiogram or a routine obstetric growth examination. The report should identify the reason for the repeat, the cardiac structures or findings reassessed, and the interpretation. For physician interpretation alone, append modifier 26; for the equipment and staff portion alone, append modifier TC. Without either modifier, the claim represents the global service. Spectral Doppler follow-up, when performed and documented, is represented separately by 76828.

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.

76826 billing questions

How does 76826 differ from 76825?

76826 is for repeat or follow-up fetal cardiac imaging. Use 76825 for a complete fetal echocardiographic examination.

Can 76826 be reported with 76828?

Yes, when the repeat or follow-up examination includes a separately performed and documented spectral Doppler evaluation. Code 76826 represents the two-dimensional imaging portion; 76828 represents follow-up Doppler echocardiography.

Which modifier identifies the interpretation only?

Append modifier 26 when billing only the physician’s interpretation. Modifier TC identifies the technical portion; no component modifier represents the global service.

What documentation supports reporting 76826?

Document why fetal cardiac imaging was repeated, what cardiac findings or structures were reassessed, and the study results and interpretation.

Is 76826 used for a routine fetal growth follow-up?

No. It represents follow-up imaging focused on the fetal heart; a routine obstetric follow-up ultrasound addresses a different examination purpose.

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.
