MO HB1700

Pharmacy benefits managers must remit detailed claim information including NDC numbers, quantities paid to pharmacies, and amounts charged to covered entities.

Pharmacy benefits managers are prohibited from automatically enrolling pharmacies in contracts, requiring participation in one contract to access another, or discriminating between pharmacies based on copayments or days of supply.

Health benefit plans cannot limit, reduce, or deny coverage for drugs currently being used by insured individuals unless making uniform changes that apply to all covered drugs.

Medication switch communications must inform patients and prescribers of the originally prescribed drug, proposed alternative, financial incentives influencing the switch, and patient rights to refuse the change.

Prescribers may override step therapy or fail-first protocols if the preferred treatment is ineffective, likely to be ineffective, or likely to cause adverse reactions, with such protocols limited to 14 days when deemed clinically ineffective.
