What is step therapy in a Medicare drug plan, and do I have to start over if I switch plans?
Answered by 4 licensed agents
If you switch Medicare drug plans, you don't necessarily have to start over. However, each plan has its own drug formulary and coverage rules, so an approval from your previous plan may not automatically carry over.
If you've already tried other medications without success, or you've been doing well on your current medication, your doctor can provide that medical history and request an exception from the new plan. If approved, you may be able to continue your medication without repeating the step therapy process.
In some cases, the new plan may also provide a temporary supply of your medication while the coverage requirements are being resolved.
This is why I always encourage people to review more than just premiums and copays when comparing Medicare plans. It's important to check whether your medications are covered and whether they have restrictions such as step therapy, prior authorization, or quantity limits. My goal is to help people understand these details before switching plans so they can avoid unexpected costs or interruptions in treatment.

This is called the, "fail first" rule: You must fill and take the Step 1 medication for a set period. If it does not control your condition, causes severe side effects, or is medically inappropriate, your doctor can request "stepping up" to a higher-tier drug
If you switch insurance companies, like going from United Health Care to Humana can trigger the entire process to start over as each company has it's own formularies (list of preferred and non preferred drugs) and coverage rules.
You are entitled to a temporary, one-time supply (typically up to 30 days) of your medication at a retail or mail-order network pharmacy within the first 90 days.
If your new plan requires step therapy for a drug you were actively taking, the transition fill must be provided free from step therapy restrictions so you do not experience an immediate interruption in care
