Multispecialty groups can create subgroups to report MVP performance information relevant to specific specialists or care teams within the larger group (also referred to as the affiliate group) so that participation is more tailored to the care they deliver, such as clinicians who provide cancer care or joint repair. In 2024, subgroup reporting is voluntary for MVP participants.
Beginning in 2026, s. CMS uses the initial 12-month segment of the 24-month MIPs determination period to determine the eligibility of clinicians intending to participate and register as a subgroup.
