Vascular intervention
About 37186: Secondary arterial thrombectomy during intervention
Reports secondary percutaneous removal of thrombus from a noncoronary artery or arterial bypass graft during another intervention in the same vascular territory.
This add-on describes secondary percutaneous thrombectomy in a noncoronary, nonintracranial artery or arterial bypass graft during another intervention in the same vascular territory. For example, an interventional radiologist or vascular surgeon may use aspiration or a snare to remove thrombus encountered during peripheral angioplasty or stenting. Fluoroscopic guidance and intraprocedural thrombolytic injections are included when performed.
Choose this code when thrombectomy is performed as a secondary technique alongside a different percutaneous intervention, rather than as the primary mechanical thrombectomy service. The operative report should identify the treated artery or graft, thrombus removal technique, and the accompanying intervention in that territory. Report it only with a qualifying primary procedure; it is paid within that procedure’s global period. CMS prices the code as bilateral, so modifier 50 does not increase payment.

37186 billing questions
When is 37186 used instead of 37184 or 37185?
Use 37186 for secondary thrombectomy performed with another percutaneous intervention, such as angioplasty or stenting. Codes 37184 and 37185 describe primary mechanical thrombectomy of the initial or an additional vessel.
Can 37186 be reported by itself?
No. It is an add-on code and must be reported with a qualifying primary percutaneous intervention in the same vascular territory.
Are fluoroscopy and thrombolytic injections separately reported?
Fluoroscopic guidance and intraprocedural pharmacological thrombolytic injections are included in the thrombectomy service when performed.
Should modifier 50 be appended for bilateral treatment?
CMS prices 37186 as bilateral, and modifier 50 does not increase payment.
What documentation supports reporting 37186?
Document the artery or arterial graft treated, the secondary thrombectomy technique, the thrombus removed, and the other percutaneous intervention performed in that vascular territory.
Where these rates come from
