MEDICARE ADVANTAGE · PART C & D STAR RATINGS

516 contracts compete.
207 earn the bonus.

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.

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, following that measurement year’s specification — 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 drops eleven measures by the 2029 Star Ratings and recalculates cut points every year. 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

ContractsMedicare Advantage Prescription Drug, and standalone Part D. Part D adherence first; Part C quality measures from your medical claims and clinical feeds.
