    Default Modifier TC - Modifier TC for following cardiology

    AAPC: Back to School
    Hello everyone

    I am very confused with modifier TC. I am working for hospital. Is it OK to use Modifier TC for following cardiology CPT codes.

    93303 (Transthoracic Echo for congenital anomalies
    93304 (same as above follow-up/Ltd study)
    93306 (ECG with color flow doppler)
    93320 (Doppler ECG pulsed wave and/continuous wave with spectral display)
    93321 (same as above follow-up or ltd study)
    93325 (Doppler ECG color flow velocity mapping)

    Thank U

    You can use Modifier TC for any procedure that has a professional (Modifier 26) and a technical component. If the hospital is supplying the techinical component of the aforementioned services, it would be correct to bill using the TC modifier.
