2021 MIPS Measure #409: Clinical Outcome Post Endovascular Stroke Treatment 

Measure Type High Priority Measure? Collection Type(s)
Outcome yes MIPS CQM


Measure Description

Percentage of patients with a mRs score of 0 to 2 at 90 days following endovascular stroke intervention


This measure is to be submitted each time an endovascular stroke intervention procedure 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.

NOTE: Include only patients that have cerebrovascular accidents through September 30 of the performance period. This will allow the evaluation of at least 90 days after the cerebrovascular accident within the performance period.

Measure Submission Type:

Measure data may be submitted by individual MIPS eligible clinicians, groups, or third party intermediaries. The listed denominator criteria are used to identify the intended patient population. The numerator options included in this specification are used to submit the quality actions as allowed by the measure. The quality-data codes listed do not need to be submitted by MIPS eligible clinicians, groups, or third party intermediaries that utilize this modality for submissions; however, these codes may be submitted for those third party intermediaries that utilize Medicare Part B claims data. For more information regarding Application Programming Interface (API), please refer to the Quality Payment Program (QPP) website.
