Michigan’s insurance regulator does not review the rates of self-funded health plans. The Department of Labor’s new pharmacy benefit manager disclosure rule is the main federal oversight for them. This page reads the rule for a Michigan employer.
The Michigan Department of Insurance and Financial Services reviews and approves health insurance rates for individual and small group plans. It states that it does not have authority over the rates charged under a self-funded health care plan, which is regulated by the U.S. Department of Labor. For a Michigan employer with a self-funded plan, the Department of Labor is therefore the agency that sets the rules.
On October 29, 2026 the Department of Labor announced a final rule requiring pharmacy benefit managers, and their affiliated brokers and consultants, to disclose their fees and compensation to the fiduciaries of large employers’ self-insured group health plans. The new disclosures cover manufacturer rebates and other payments, compensation when the plan’s price exceeds the pharmacy’s reimbursement, and payments recouped from pharmacies. The rule also lets fiduciaries audit the accuracy of a PBM’s disclosures.
A law-firm summary published November 2, 2026 reports that the rule applies to self-insured plans of employers with at least 100 employees, and certain other self-insured plans with at least 100 participants, and reports an applicability date of plan years beginning on or after July 1, 2027. Many Michigan employers sit near that line, so the first step is to confirm whether the plan is self-insured, level-funded or fully insured. Check the rule text for the thresholds.

No. DIFS states it does not have authority over the rates charged under a self-funded health care plan. Those plans are regulated by the U.S. Department of Labor.
It depends on how the plan is structured and its size. The rule is reported to apply to self-insured plans with at least 100 employees or participants, so many smaller level-funded plans may fall outside it. Send us the contract and we will look.
The law-firm summary reports that fully insured plans are excluded from the detailed requirements. Your carrier’s own filings and DIFS review still apply to the rate.
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.
No. We are benefits consultants, not attorneys. Read the final rule and talk to your counsel about your plan’s obligations.
