Comprehensive Medication Review (CMR)

A Comprehensive Medication Review (CMR) is an interactive, one-on-one review of all of a patient's medications, usually done by a pharmacist. It is the core service of Medicare Part D Medication Therapy Management. It ends with a written summary, an action plan, and a medication list. Part D plans must offer one to MTM-enrolled members at least once a year.

What a Comprehensive Medication Review is

A CMR covers prescriptions, over-the-counter drugs, herbal products, and supplements. The pharmacist or other qualified provider looks for problems such as interactions, duplicates, side effects, and cost barriers. The patient gets a written summary in CMS's standardized format, with an action plan and a personal medication list. It can happen in person or by telehealth.

Part D plans must offer a CMR at least once a year to members enrolled in MTM. To qualify, plans can require no more than 3 chronic diseases and no more than 8 Part D drugs. There is also a cost threshold, $1,276 in 2026. The CMR completion rate is scored in the 2026 Star Ratings.

For the 2027 Star Ratings, CMR completion is display-only, and it returns as a new measure in the 2029 Star Ratings. Most of the work is reaching people. Rivvi is a HIPAA-compliant AI workspace where pharmacy staff can upload an MTM-eligible list and track who is done. Its action layer calls and texts patients to offer the review.

Questions

Comprehensive Medication Reviews, answered

What is included in a CMR?
A CMR reviews every medication the patient takes, including over-the-counter products and supplements. The pharmacist checks for interactions, duplicates, side effects, and adherence or cost problems. The patient receives a written summary with a medication action plan and a personal medication list in CMS's standardized format.
Is the CMR completion rate still a Star Ratings measure?
It was scored in the 2026 Star Ratings. For the 2027 Star Ratings it moved to the display page, so it does not count toward the rating. CMS says it returns as a new measure beginning with the 2029 Star Ratings.
Who can perform a CMR?
A pharmacist usually performs it, but Part D rules also allow another qualified provider. It must be interactive and in real time, either in person or by telehealth. The patient takes part, or someone on their behalf, such as a caregiver.
CMR vs MTM: what is the difference?
MTM is the whole Part D program: targeting eligible members, annual CMRs, quarterly targeted medication reviews, and follow-up. The CMR is the program's core annual service. Every CMR is part of MTM, but MTM also includes the reviews that happen between CMRs.
