For some drugs, there may be a post-quantity limit authorization available. Your doctor will need to contact Caremark at 800.294.5979 (number is for doctors and their staff only) and provide clinical information to request an amount over the plan limit. As the plan’s pharmacy benefits manager, Caremark will review this information and decide if the insurance plans should cover the amount above the limit. Some drugs have a set quantity limit and the plans will not pay for a quantity beyond that. Anything over that limit must be paid by the member.
