Drug tiers

Option introduced in the Medicare prescription drug plan that allows each plan to group different drug types together (i.e., generic, brand, preferred brand). Tiers could be used to describe drug groups that are based on classes of drugs. If the tier option is used, the plan should provide clarification on the drug types covered under the tier in the prescription drug plan notes section.

drug utilization review (DUR)

Evaluation of prescription drug use and prescribing patterns by physicians to establish the appropriateness of drug treatment. DUR may be done for individual patients, an entire insured group, for current, past, or future usage. Medication costs may be reduced by substituting generic for brand name drugs and use of a drug formulary.
