What 37270 covers
This add-on service represents stent treatment of an additional vessel in the femoral-popliteal territory when the intervention meets billing code’s complex criteria. Vascular surgeons, interventional radiologists, and interventional cardiologists may perform it in a catheterization or angiography suite for lower-extremity arterial disease. The code distinguishes the additional treated vessel from the first vessel and from simpler interventions; the record should identify the vessel treated, the stent procedure, and the facts supporting complex classification.
Report 37270 with the applicable primary procedure for the first complex stented vessel, such as 37269, and count each additional qualifying vessel rather than each stent. The code is an add-on and is paid within the primary procedure’s global period. For bilateral procedures reported with modifier 50, CMS pays this code at 150%. When atherectomy is also performed in the same vessel, use the applicable combination code rather than reporting this stent-only code with a separate atherectomy code for that vessel.

How to choose
- 37269Arterial stenting
- This is the first-vessel code for complex femoral-popliteal stenting. Use 37270 for additional qualifying vessels in the same treatment.
- 37268Arterial stent
- Both codes concern additional-vessel stenting, but 37268 is for simple treatment and 37270 is for treatment meeting complex criteria.
- 37278Stent and atherectomy
- 37278 represents complex stenting with atherectomy in an additional vessel; 37270 represents complex stenting without that combination.
- 37266Angioplasty
- 37266 is for complex angioplasty of an additional vessel without stent treatment. Use 37270 when the qualifying additional vessel receives a stent.
37270 billing questions
How does 37270 differ from 37269?
37269 reports the first complex stented vessel in the femoral-popliteal territory. Use 37270 for each additional vessel meeting the complex criteria.
Do units represent stents or vessels?
Units represent additional treated vessels, not the number of stents deployed. Document each vessel and the intervention performed there.
Can 37270 be reported by itself?
No. It is an add-on code and must be reported with an applicable primary procedure, such as 37269 for the first complex stented vessel.
Can angioplasty or atherectomy also be reported for the same vessel?
Angioplasty performed as part of the stent treatment is not separately represented by this code. If atherectomy is performed in that vessel, use the applicable stent-and-atherectomy combination code.
How is bilateral reporting handled?
CMS pays this code at 150% when a bilateral procedure is reported with modifier 50. The documentation should support treatment on both sides.
