75573 or 75574
Question:
If a child has a cardiac congenital defect such as TOF repaired, should the follow up imaging be ordered/coded as non-congenital? Our practice routinely performs CT Heart post surgical repair that comes over ordered as 75573 (congenital) but our coders feel this should be 75574 (non-congenital).
"EXAMINATION: CT HRT W/3D IMAGE CONGEN.
CLINICAL HISTORY: 17-year-old with repaired Tetralogy of Fallot presents for evaluation of pulmonary arteries.
Technique: CT angiogram (CTA) of the heart with prospective gating and volumetric (wide axial) technique on a Canon AquilionOne CT scanner.

Before contrast injection, the heart rate was 56 bpm. Heart rate during the study was 49 bpm regular. CTDI used during the CTA portion was 6.9 mGy. Total DLP 110.9 mGy-cm."
