What 92924 covers
An interventional cardiologist typically performs this service in a cardiac catheterization laboratory, using a catheter-based atherectomy device to modify or remove coronary plaque and balloon angioplasty to treat the narrowed vessel. The code covers treatment of one major coronary artery or branch when atherectomy and angioplasty are performed without stent placement in that vessel.
Select the code from the procedure actually performed: the report should identify the treated artery or branch, atherectomy, balloon angioplasty, and whether a stent was placed. Angioplasty in the treated vessel is included, so it is not separately reported for that same work. The code has a 0-day global period, which includes same-day preoperative and postoperative care. When other separately payable procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is not appropriate for this coronary-vessel service. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

92924 billing questions
When should I choose 92924 instead of 92920?
Use 92924 when coronary atherectomy and balloon angioplasty are performed in the treated artery or branch. Code 92920 describes coronary balloon angioplasty without atherectomy.
Can I report 92920 separately for the balloon angioplasty?
No. The angioplasty performed in the artery treated with atherectomy is included in 92924.
What if a stent is placed in the atherectomy-treated artery?
Use 92933 for atherectomy with stent placement and angioplasty when performed. Do not report 92924 for that same treated artery.
How do I report atherectomy in another branch?
Code 92925 is the add-on for each additional qualifying branch treated with atherectomy and angioplasty. Document the additional treated branch in the procedure report.
Can modifier 50 be used for treatment of both sides?
No. Modifier 50 is not appropriate for this coronary-vessel service; use the applicable coding for each treated artery or branch.
What documentation supports reporting 92924?
The operative report should identify the target coronary artery or branch and describe both atherectomy and balloon angioplasty. It should also state whether a stent was placed, since that changes the code selection.
