Coding for cardiology may contain some complex circumstances that lead to coding errors and denials. 2022 arrived with some noteworthy changes for cardiology coding, including new congenital cardiac codes. By grasping a better understanding of the codes and rationale behind them, cardiology CPT® coders and healthcare compliance professionals can better overcome any challenges while coding correctly. Let’s explore the foundations of these codes for future success.
Below are the new codes for 2022 with full descriptions.
| 93593 | Right heart catheterization for congenital heart defect(s) including imaging guidance by the proceduralist to advance the catheter to the target zone; normal native connections |
| 93594 | abnormal native connections |
| 93595 | Left heart catheterization for congenital heart defect(s) including imaging guidance by the proceduralist to advance the catheter to the target zone, normal or abnormal native connections |
| 93596 | Right and left heart catheterization for congenital heart defect(s) including imaging guidance by the proceduralist to advance the catheter to the target zone(s); normal native connections |
| 93597 | abnormal native connections |
| +93598 | Cardiac output measurement(s), thermodilution or other indicator dilution method, performed during cardiac catheterization for the evaluation of congenital heart defects
(List separately in addition to code for primary procedure) |
So, what are some of the circumstances when each code should be used? For 93598, the code can be used in conjunction with 93593, 93594, 93595, 93596, and 93597. When it comes to indicator dilution studies such as thermodilution for cardiac output measurement during cardiac catheterization for congenital heart defect[s], use 93598 as well. However, it should not be reported in conjunction with 93451-93461. When it comes to pharmacologic agent administration during cardiac catheterization for congenital heart defect[s], use 93463.
When performing a physiological exercise study with cardiac catheterization for congenital heart defect[s], 93464 should be reported. For contrast injections during cardiac catheterization for congenital heart defect[s], see 93563, 93564, 93565, 93566, 93567, and 93568.
What should you do for reporting services such as angiography or venography that are not described in the 90000 series code section? In this circumstance, you will need to see appropriate codes from the Radiology section and the Vascular Injection Procedures subsection in the Surgery/Cardiovascular System section. As for transseptal or transapical access of the left atrium during cardiac catheterization for congenital heart defect[s], report 93462 in conjunction with 93595, 93596, and 93597.
Also, understand that for existing codes as well for 2022, several have parenthetical changes due to congenital heart defect code changes:
