When should a Michigan employer act?
The reported applicability date is plan years beginning on or after July 1, 2027. A good-faith enforcement policy is reported to run until then, so asking your PBM questions this renewal is reasonable.
Timing for a Michigan employer
The law-firm summary reports an applicability date of plan years beginning on or after July 1, 2027 and a good-faith enforcement policy until then. A Michigan employer with a January plan year has its first covered renewal in 2028.
There is no reason to wait. Asking your PBM about rebates, spread and recoupments at your next renewal puts you ahead and gives you a baseline.
Building a calendar for the rule’s dates
The law-firm summary we relied on reports an applicability date for plan years beginning on or after July 1, 2027, and a good-faith enforcement policy since February 3, 2026. Because dates depend on your plan year, find the first plan year that falls under the rule and work backward.
A practical plan has three steps: list your pharmacy benefit manager and the contract term, mark the date when the rule applies to your plan year, and schedule a contract review ahead of that date. We help set that calendar and prepare questions for the review.
