About 37185: Additional-vessel arterial thrombectomy
Report for mechanical thrombectomy of an additional arterial vessel in the same vascular family during a primary thrombectomy session.
This add-on represents catheter-based mechanical removal of thrombus from an additional artery in the same vascular family as the vessel treated primarily. Interventional radiologists and vascular surgeons commonly perform the work in an angiography suite or operating room. The thrombectomy may involve intraprocedural thrombolytic medication and fluoroscopic guidance as part of the service. The additional vessel must be distinct from the initial vessel treated under the primary thrombectomy service.
Report 37185 with the primary arterial thrombectomy code for the initial vessel, not as a stand-alone service. The operative or procedure report should identify the additional vessel and document mechanical thrombectomy there, along with the relationship to the primary treatment. CMS treats this as an add-on paid within the primary procedure's global period. The code is already priced as bilateral, so modifier 50 does not increase payment.

37185 billing questions
When should 37185 be reported instead of 37184?
Use 37184 for the initial arterial vessel treated with primary mechanical thrombectomy. Report 37185 for each qualifying additional vessel in the same vascular family.
Can 37185 be billed by itself?
No. It is an add-on and must be reported with the primary procedure for the initial vessel.
What documentation supports reporting an additional vessel?
The procedure report should identify the additional artery and document mechanical thrombectomy performed there, distinct from the initial vessel.
Should modifier 50 be appended for bilateral treatment?
The code is already priced as bilateral. Modifier 50 does not increase payment.
How does 37185 differ from 37186?
37185 identifies primary mechanical thrombectomy in an additional vessel within the same vascular family. Code 37186 describes a secondary arterial thrombectomy service rather than this additional-vessel primary service.
