What limitation is placed on prescription drug coupons regarding government insurance programs?

Prescription drug coupons are often limited for use by patients enrolled in government insurance programs such as Medicaid and Medicare due to regulatory restrictions. These programs have specific guidelines and policies regarding the coverage and reimbursement of medications. When drug coupons are utilized, they could interfere with the standard reimbursement processes and the cost-sharing structure that government programs have in place.

By not allowing these coupons to be used by patients benefiting from government insurance, it ensures that there is no disruption in the intended financial framework of these programs. This limitation helps maintain the integrity of the public health insurance systems, as well as ensuring that patients receive their medications through the appropriate channels without the influence of coupon promotions, which might otherwise compromise the funding models for these programs.
