Which factor should be reviewed to assess potential changes in medication coverage under a new plan?

• A. The network size
• B. The overall costs
• C. The formulary status for medications, including tiers and utilization management
• D. The provider's credentials

Answer: (C)

When assessing how a new plan could change medication coverage, the key factor to review is the formulary status for medications, including tiers and utilization management. The formulary is the plan’s approved list of drugs and it directly determines whether a medication is covered and at what cost. Tier placement affects copay or coinsurance amounts, and utilization management rules like prior authorization, step therapy, and quantity limits can restrict access or delay approval. If the plan changes, a drug you currently take might move to a higher tier, require authorization, or even be excluded, altering both access and out-of-pocket costs. While network size, overall costs, and a provider’s credentials matter for other reasons, they don’t determine whether a specific medication is covered under the plan.
