What 37243 covers
An interventional radiologist or other qualified physician delivers embolic material through a catheter to reduce or stop blood flow to a tumor or targeted organ. Common settings include hospital interventional radiology suites, where procedures may address liver tumors, uterine fibroids, or benign prostatic hyperplasia. The embolic agent and catheter approach depend on the target vessels and treatment plan.
Choose this code when the embolization is performed for a tumor or to produce organ ischemia or infarction; embolization for bleeding or other arterial and venous indications belongs to different codes in the family. The report should identify the clinical indication, target organ or tumor, vessels treated, embolic technique, and imaging guidance. The code includes same-day preoperative and postoperative care under its 0-day global period. When multiple procedures occur in one session, CMS pays the highest-valued procedure in full and reduces the others by 50%. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery and does not permit co-surgeon or team-surgery payment.

37243 billing questions
When should this code be chosen instead of arterial embolization code 37242?
Use 37243 when the purpose is tumor treatment or organ ischemia or infarction. Code 37242 describes an arterial embolization for another indication, such as a vascular malformation or aneurysm.
How does this code differ from embolization for bleeding?
Use 37244 when the embolization treats hemorrhage. The indication for 37243 is a tumor or intended organ ischemia or infarction.
Can the imaging used to guide embolization be separately reported?
The code includes the imaging guidance, intraprocedural roadmapping, and radiological supervision and interpretation necessary to complete the intervention. Do not separately report those included services as though they were separate guidance for the same embolization.
Should modifier 50 be appended for embolization on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
What happens when other procedures are performed in the same session?
CMS pays the highest-valued procedure in full and reduces the other procedures by 50% under the standard multiple procedure rule.
Does Medicare pay an assistant or co-surgeon for this procedure?
CMS lists a statutory restriction on assistant-at-surgery payment and does not permit co-surgeon or team-surgery payment for this code.
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.
