Material Change Transaction Notices (MCN) and Cost and Market Impact Review (CMIR)

Consolidation in the health care market is common, and can be an underlying driver of high prices. The Office of Health Care Affordability (OHCA) is responsible for reviewing and evaluating consolidation, market power, and other market failures through cost and market impact reviews of mergers, acquisitions, or corporate affiliations involving health care service plans, health insurers, hospitals, physician organizations, pharmacy benefit managers, and other health care entities. This review begins with a notice of material change transaction on the part of a health care entity.  OHCA reviews the transaction, and if warranted, conducts a full cost and market impact review.

 Below is the list of notices of material change transactions submitted to OHCA. Members of the public who wish to submit comments regarding a specific Notice can send an email to by the anticipated OHCA review completion date indicated in the Notice document.
