2026 MIPS Measure #465: Uterine Artery Embolization Technique: Documentation of Angiographic Endpoints and Interrogation of Ovarian Arteries

The percentage of patients with documentation of angiographic endpoints of embolization AND the documentation of embolization strategies in the presence of unilateral or bilateral absent uterine arteries.

This measure is to be submitted each time a procedure for uterine artery embolization is performed during the performance period. This measure may be submitted by Merit-based Incentive Payment System (MIPS) eligible clinicians who perform the quality actions described in the measure based on the services provided and the measure-specific denominator coding.

All patients undergoing uterine artery embolization for leiomyomas and/or adenomyosis

All patients, regardless of age

AND

Diagnosis for leiomyomas or adenomyosis (ICD-10-CM): D25.0, D25.1, D25.2, D25.9, N80.00, N80.01, N80.02, N80.03

AND

Patient procedure during the performance period (CPT): 37243

Number of patients undergoing uterine artery embolization for symptomatic leiomyomas and/or adenomyosis in whom embolization endpoints are documented separately for each embolized vessel AND ovarian artery angiography or embolization performed in the presence of variant uterine artery anatomy

Embolization Endpoints –

Complete stasis (static contrast column for at least 5 heartbeats)
Near-stasis (not static, but contrast visible for at least 5 heartbeats)
Slowed flow (contrast visible for fewer than 5 heartbeats)
Normal velocity flow with pruning of distal vasculature
Other [specify]
Not documented
Variant uterine artery anatomy – Treatment strategy:

Not applicable – Normal uterine artery anatomy
Ovarian artery angiography
Ovarian artery embolization
Abdominal aortic angiography
No additional angiography or embolization performed

Performance Met: Embolization endpoints are documented separately for each embolized vessel AND ovarian artery angiography or embolization performed in the presence of variant uterine artery anatomy (G9962)

OR

Performance Not Met: Embolization endpoints are not documented separately for each embolized vessel OR ovarian artery angiography or embolization not performed in the presence of variant uterine artery anatomy (G9963)

The efficacy of uterine artery embolization is related to incomplete embolization. The two failure mechanisms that contribute are (1.) appropriate vessel selection but insufficient embolization and (2.) incomplete identification of uterine arterial supply. This measure ensures documentation of two important procedural aspects of uterine artery embolization, which are known to be associated with treatment efficacy: (1.) appropriate embolization endpoints achieved and (2.) delineation of all uterine arterial supply with embolization where possible.

Inadequate arterial embolization alone is a known cause of treatment failure. 1 The ovarian arteries often provide an alternate route of arterial supply to the uterus when the uterine artery is occluded or absent; however routine aortography is not recommended when conventional uterine artery anatomy is present. 2
