MEDICARE ADVANTAGE · PART D STAR RATINGS
516 plans compete.
207 get paid.
What separates them is a few hundred members whose prescriptions ran out early — and who can still be reached. AdherenceStar finds them while the year can still be saved.
Built for plans that carry the Stars number without a data-science team behind it.
Where the gap is widest% OF MA ENROLLMENT BELOW 4★
Nationally, 30% of Medicare Advantage enrollment sits in a contract rated below 4 stars — earning no benchmark bonus. Montana is the widest gap; Rhode Island (6%) the narrowest.
ONE MEMBER, ONE YEAR
Adherence is a ceiling that falls.
Every uncovered day permanently lowers the best result a member can still reach. Miss enough of them and eighty percent becomes unreachable — months before anyone would notice on a year-end report.

WHY THIS IS DIFFERENT
Most tools tell you who failed. We tell you who you can still save.
01Your rates are computed hereProportion of days covered, calculated member by member from your own claims against the exact specification for that measurement year — then reconciled line by line against your official CMS report before anyone acts on it.
02Recoverability, not another gap listAny report can name your non-adherent members. We compute the date each one becomes mathematically unreachable, and rank by what the recovery is worth in star movement.
03Rule changes arrive as contentCMS retires eleven measures by 2029 and moves every cut point annually. Each measurement year ships as a versioned rulepack — an update you receive, not a release you wait for.
04Your team keeps the workNo delegated clinical staff, no multi-month integration. Upload two files and see where you stand the same day. The plan keeps the members, the outreach, and the relationship.
WHO THIS IS FOR
