What 92937 covers

An interventional cardiologist uses catheter-based techniques to restore blood flow in or through one coronary bypass-graft vessel. The treated conduit may be a saphenous vein graft, an internal mammary artery graft, or another free arterial graft; treatment may also reach the native coronary artery through the graft. The service is typically performed in a hospital catheterization laboratory. Angioplasty, atherectomy, stenting, and distal embolic protection when performed are encompassed in this graft revascularization service.

Report one unit for the treated vessel, and use the additional-branch code when another eligible branch is treated. The procedure report should identify the graft, target vessel or branch, treatment performed, and any embolic protection. Same-day preoperative and postoperative care is included in the 0-day global period. When multiple procedures in the same session are subject to the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate; co-surgeons and team surgery are not permitted. Assistant-at-surgery payment requires documentation of medical necessity.

How to choose

92928Coronary stentingOne artery or branch
Use 92937 for revascularization of or through a coronary bypass graft. Use 92928 for stent treatment of a native coronary artery.
92941Coronary revascularizationAcute MI, one vessel
92941 identifies revascularization of a total occlusion during acute myocardial infarction. This code describes graft revascularization without that acute-infarction circumstance.
92943CTO PCIAntegrade approach
92943 is for revascularization of a chronic total occlusion. Choose the graft revascularization code when the service is not reported under the chronic-total-occlusion code.

92937 billing questions

When is this code chosen instead of a native-coronary intervention code?

Use it when the treated vessel is a coronary bypass graft or the intervention reaches the target through that graft. Native-coronary intervention codes describe treatment of a native vessel rather than graft revascularization.

Are angioplasty, atherectomy, and stenting reported separately for the same graft vessel?

They are encompassed in this service when performed on the treated graft vessel. Distal embolic protection is also included when performed.

How should an additional treated branch be reported?

Report the primary graft revascularization code for the first vessel and the applicable add-on code for each eligible additional branch. The operative report should distinguish the treated branches.

Can modifier 50 be used for treatment of grafts on both sides?

No. Modifier 50 is inappropriate for this code.

What documentation supports assistant-at-surgery payment?

The record must document the medical necessity of the assistant's participation. Assistant-at-surgery payment is limited to cases supported by that documentation.

What same-session payment reduction may affect this service?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other eligible procedures in the same session are paid at 50%.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
