The article explains how formularies, drug tiers, pharmacy networks, and annual plan changes can affect prescription costs and access.
CHARLESTON, S.C., Oct. 6, 2026 /PRNewswire/ — Many Medicare Advantage members assume that having drug coverage means they are fully protected from high pharmacy costs. That assumption is challenged in a HelloNation article featuring Caroline Edwards of the Senior Savings Network in Charleston, South Carolina. The article explains why reviewing prescription drug coverage within a Medicare Advantage plan is essential and highlights the risks of overlooking key details.
According to the article, Medicare Advantage plans that include drug coverage follow Part D rules but are not standardized. Medicare Expert Caroline Edwards explains that each insurer creates its own formulary, which determines which medications are covered, how they are tiered, and what members pay out-of-pocket. These formularies can differ dramatically between plans, even when medical coverage and premiums appear similar.
One major point raised in the HelloNation feature is how drug tiers affect cost. Formularies often divide medications into levels. Generic drugs tend to be placed in lower tiers with smaller co-pays, while brand-name or specialty medications appear in higher tiers and come with higher costs. Edwards notes that two plans may both cover the same drug, but they might place it in different tiers, creating significant differences in pharmacy expenses.
The article also discusses prior authorization and step therapy, which are two requirements that can delay or restrict access to medication. Some drugs must be pre-approved by the insurance company, and others require patients to try lower-cost alternatives before coverage is granted. Medicare Expert Caroline Edwards emphasizes that many members only learn about these rules when trying to fill a prescription, which can cause delays in treatment.
Pharmacy network participation also affects drug prices. Medicare Advantage plans often include preferred pharmacy networks where co-pays are lower. Using a non-preferred pharmacy can raise costs significantly, which may come as a surprise to those who rely on a specific local pharmacy. The article points out that mail-order services may reduce costs for some but are not suitable for everyone, particularly those who travel frequently or need urgent refills.
Even a Medicare Advantage plan with a zero-dollar premium can result in high out-of-pocket costs if the prescription drug coverage does not align with a member’s specific medication needs. Edwards stresses that evaluating a plan based only on its premium can lead to financial strain at the pharmacy counter.
The HelloNation article also explores how drug coverage can change from year to year. Insurers are allowed to update their formularies annually, which means a drug covered one year may move to a higher tier or be excluded entirely the next. Edwards advises reviewing the Annual Notice of Change to identify these updates before they result in surprise costs.
Another aspect discussed is the Medicare Part D coverage gap, commonly known as the donut hole. Although this gap has become less severe in recent years, people who take several medications may still encounter increased costs after reaching certain spending limits. Plans apply cost-sharing differently during this phase, which can impact the total yearly drug spend.
Specialty medications deserve special attention. These drugs are often expensive and used to treat complex or chronic conditions. Instead of co-pays, many Medicare Advantage plans apply coinsurance, meaning members pay a percentage of the drug’s total cost. Even a small percentage can result in high out-of-pocket costs each month.
Quantity limits are also addressed in the article. Some plans restrict how much of a medication can be filled at once. These limits can be frustrating for people managing long-term therapies and may cause interruptions if not planned for in advance. Understanding these limits is another way to prevent unexpected access issues.
The article encourages people to review their drug coverage each year using an accurate and current list of medications, including dosage and pharmacy preferences. Medicare Expert Caroline Edwards points out that choosing a plan without this information often leads to costly assumptions. The key is not just whether drug coverage is included but how well it matches a person’s actual prescriptions.
