Question: Utah Subscriber Answer: You should be aware also of the correction to the note under 36215, which should read, "For catheter placement for coronary angiography, see 93454-93461." And the second instruction above 75557 (Cardiac magnetic resonance imaging for morphology and function without contrast material) should read, "For cardiac catheterization procedures, see 93451-93572." Under +93662 (Intracardiac echocardiography during therapeutic/diagnostic intervention, including imaging supervision and interpretation [List separately in addition to code for primary procedure]), check the parenthetical instruction to "Use 93662 in conjunction with ..." As printed, the third code listed is 93543. That is a typo, and you should delete the code. In its place, you should add 93453 (Combined right and left heart catheterization includin intraprocedural injection[s] for left ventriculography, imaging supervision and interpretation, when performed). You also should check the index entry for Catheterization; Cardiac; Combined Left and Right. The subentries for Right Atrial and Right Ventricular should point you to 93566 (Injection procedure during cardiac catheterization including imaging supervision, interpretation, and report; for selective right ventricular or right atrial angiography [List separately in addition to code for primary procedure]) instead of 93565. Check the Corrections document regularly for updates. You also can read more about AMA errata in Cardiology Coding Alert, vol. 14, no.
