External review of coverage denials

If the internal appeal is denied, request external independent review. In Michigan, this review is conducted by an independent organization with no ties to your insurer, and the decision is binding -- your insurer must comply. External reviews overturn a meaningful share of denials — roughly 40% under the federal HHS process and up to ~60% in stricter states (California DMHC IMR data).
Michigan has a unique healthcare landscape shaped by the auto industry's legacy of employer-sponsored coverage and the state's large Medicaid expansion population. The Department of Insurance and Financial Services (DIFS) provides consumer advocacy and oversees the external review process under MCL 550.1911.
Michigan DIFS resolved over 12,000 consumer complaints in the most recent reporting year. The department's Consumer Services team provides free assistance with insurance disputes and can facilitate communication between consumers and insurers during the appeal process.
If your denial came from one of these major Michigan insurers, AppealArmor generates appeal letters tailored to their specific policies and appeal processes.

For situations where the standard timeline could seriously jeopardize your health, Michigan law requires expedited review within 72 hours. DIFS can facilitate expedited review requests when your physician certifies medical urgency.
Michigan consumers frequently encounter these denial types. The state's auto industry legacy means many residents have employer-sponsored plans with complex prior authorization requirements.
Prior authorization denials are the most frequently reported issue to DIFS. Michigan insurers require prior auth for most specialty care, imaging, and high-cost medications. DIFS Consumer Services can help facilitate communication with your insurer during the prior auth appeal.
