What is Prescription Drug Coverage?

Prescription drug coverage is a key part of most health insurance plans. It helps pay for prescribed medications.
Coverage extent varies between plans. Review your plan’s specifics.
Plan Formularies and Tiers
Each health plan has a formulary (drug list). It lists covered medications and their costs. This is where drug tiers come in.
Understanding Drug Tiers
Drugs are grouped into tiers, usually based on cost and type. Tiers often determine your copayment for prescription medications. The typical breakdown looks like this:
| Tier | Drug Type | Cost |
|---|---|---|
| Tier 1 | Generic Drugs | Lowest Copay (e.g., $10) |
| Tier 2 | Preferred Brand-Name Drugs | Medium Copay (e.g., $25) |
| Tier 3 | Non-Preferred Brand-Name Drugs | Higher Copay (e.g., $50) |
| Tier 4/Specialty Tier | Specialty Drugs | Highest Copay/Coinsurance |
Generic drugs, as effective as brand-name counterparts, are in lower tiers with lower copays. Your copayment depends on the drug tier.
Brand-name drugs cost more. Specialty drugs, like Eliquis, usually have higher copays or deductibles. Review your out-of-pocket costs for Tier 4 and specialty tier medications.
Your doctor can discuss more affordable medication options. Consider generic alternatives to brand-name drugs when available.
| Tier Level | Description | Copay |
|---|---|---|
| Tier 1 | Generic | $15 |
| Tier 2 | Preferred Brand | $50 |
Understand your drug tiers to minimize expenses. Check your drug’s tier before filling prescriptions.
Cost-Sharing: Deductibles, Copays, and Coinsurance
Cost-sharing is how you split costs with your insurer. These include insurance coverage, drug costs, health plans, and the health insurance plan aspects of healthcare reform.
- Copays: Set amounts for prescriptions based on their tier. Some copays apply before your deductible.
- Coinsurance: You pay a percentage of the drug’s cost.
- Integrated Deductibles: Medical and prescription costs combined. Your plan may still offer copays or coinsurance toward your prescription drugs before the deductible is met.
- Prescription Drug Deductibles: Similar to medical deductibles, you pay this amount before coverage begins. An out-of-pocket maximum protects you from excessive spending. Prescription costs are often capped to reasonable fees. Rising prescription drug costs at pharmacies can be significant without insurance. Deductible plans are regulated. Many plans combine prescription costs with other medical expenses toward an out-of-pocket maximum. While most plans have this protection, Medicaid patients may face higher caps. Do not overuse medications expecting insurance to cover all costs.
- Focus on effective treatments to avoid expensive higher-tier care. Look at information available on your insurer’s website about drug formularies, coverage, and how your insurance company defines each formulary tier. Consider various plan options carefully and take into account factors that vary depending on each drug tier.
- Look for helpful guides from plan insurance companies about drug plan coverage. Watch out for navigation timeouts, especially regarding prior authorization requirements, on insurance sites. Be mindful of mixing drug coverage tiers as they might lead to costly, unexpected effects as found by one source.
Prescription Drug Coverage Under Medicare

Medicare beneficiaries have specific prescription drug coverage options.
Medicare Part D
Medicare Part D is a stand-alone plan working with Original Medicare (Parts A and B). You pay a monthly premium for Part D. Most Part D plans offer broad drug coverage. Check the drug formulary for specific inclusions.
Medicare Advantage (Part C)
Many Medicare Advantage (Part C) plans include prescription drug coverage (Part D). Medicare Advantage plans often offer the supplemental integrated plans many beneficiaries require. These plans are important for those who don’t have employer-sponsored coverage. Excessive use of medications within a plan raises costs for Medicare.
Original Medicare is basic and requires supplemental coverage for many. Most retirees now have Medicare Advantage or similar private plans offering supplemental services. Many employer plans used to offer prescription drug benefits to retirees; this is less common now. Most beneficiaries have Medicare Advantage Plus or equivalent. It helps fill the gaps that are in Original Medicare. Consider potential for fraudulent markets and select only necessary coverage. Few beneficiaries don’t have supplemental coverage and those that don’t are typically covered by their employer.
Maximizing Your Prescription Drug Benefits

Proactive steps maximize benefits. Consult your healthcare provider and insurer about prescription drug options within your plan. This will help in making informed health and financial decisions.
Discuss generic alternatives, and check your plan’s drug list (four-tier drug list). Look for programs offering help from your insurance company. Also compare how prescription coverage works for drugs covered by plans, such as by reviewing essential health plans with insurance companies or healthcare reform guidelines that offer protection regarding the benefits plans provide for consumers.
Contact drug manufacturers about cost assistance. Explore discount programs or coverage for specific conditions offered by manufacturer’s plans. Consult resources such as the insurance glossary. Also, find out whether other healthcare insurance providers cover certain conditions within similar insurance plan offerings for healthcare services for healthcare costs at an insurance company.
Appeal coverage denials within your insurance policy. Cheaper generic versions or alternatives might exist for your medications, such as via a prior authorization.
Conclusion
Understanding prescription drug coverage and its associated health insurance plans, including deductibles and out-of-pocket maximums, can be difficult. Research health insurance plans, insurers, drug tiers, and any special programs offering financial aid or discounts. Contact your insurers about your plan coverage for healthcare services covered within the policy.
Proactive communication maximizes plan benefits, prescription coverage, and cost savings while using healthcare reform protections for healthcare costs.
FAQs about Prescription Drug Coverage: Understanding Your Benefits
What is the prescription explanation of benefits?
The prescription explanation of benefits (EOB) details processed claims. It shows the medication cost, your out-of-pocket expense, and deductible, copay, or coinsurance amounts. Specifics vary with integrated health agreements and supplemental care programs.
Medicare and Medicare Advantage Plan supplemental benefits affect costs significantly for retirees. Rising supplemental Medicare costs, high “advantage premiums”, and the financial constraints faced by retirees increase the need for plans offering comprehensive, integrated services. Understanding plan offerings, step therapy protocol, and healthcare reform can provide essential information and minimize out-of-pocket expenses, for generic and brand-name drugs.
How does prescription coverage work?
Prescription coverage uses tiered formularies. Lower tiers (generics) cost less. Insurers’ “preferred” brands are usually discounted due to agreements with manufacturers.
“Non-preferred” brands cost more. Specialty drugs are often the most expensive. Prior authorizations may be needed for specialty drugs and other non-formulary medications. You should compare various drug plan options. Review insurers’ sites for information on prior approvals and coverage specifics before selecting a drug plan.
What are the four stages of prescription drug coverage?
Many Medicare Part D plans have four stages, but not all. Some have more complex programs due to varying Medicare rules, regional circumstances, and grandfathered healthcare forms. The cost of the drug plan and whether they use the tiered cost system will depend heavily on the offerings by individual Medicare Part D providers. Some plans integrate various costs while others separate each service. Typical plans need higher deductible payments. However, some plans offer income-based discounts, step therapy programs, or rebates. Low-income patients can often check for special programs on insurers’ websites.
- Deductible Phase.
- Initial Coverage Phase.
- Coverage Gap Phase.
- Catastrophic Phase.
Original Medicare coverage varies by state. Most require patients to pay deductibles and coinsurance upfront or after services, unless additional Medicare or tiered coverage applies.
What is a prescription drug coverage determination?
A prescription drug coverage determination is your insurer’s decision on covering a medication. Pre-approval is usually required for non-formulary and newer medications. Grandfathered plans might require authorization for non-formulary prescriptions on Part D.
What is the difference between step therapy and prior authorization?
While both step therapy and prior authorization are utilization management tools used by prescription drug plans to control costs and ensure appropriate medication use, they work differently and serve distinct purposes. Prior authorization is a broader requirement where you or your doctor must get approval from your insurance plan before the plan will agree to cover certain medications, typically expensive drugs or those with safety concerns. The insurance company requires your physician to verify that the specific medication is medically necessary for your particular condition, and in some cases, to demonstrate that you’ve met certain clinical criteria before the drug will be covered. In contrast, step therapy is a specific type of prior authorization that requires you to try one or more less expensive medications that have been proven effective for most people with your condition before your plan will cover a more expensive drug for the same condition. With step therapy, you must essentially “step” through a sequence of medications, usually starting with generic drugs or preferred brand-name drugs, before you can move up to more expensive brand-name or specialty medications. For example, if you have high cholesterol and your doctor prescribes an expensive medication, your plan might require you to first try a generic statin like atorvastatin (Lipitor) or simvastatin (Zocor) before they’ll cover the more expensive drug. However, both prior authorization and step therapy requirements can be challenged through an exception process if your doctor provides a supporting statement explaining why the less expensive drug would not be effective for you, would cause adverse effects, or has already been tried without success. Your plan must typically make a decision on exception requests within 72 hours, or within 24 hours if your doctor requests an expedited decision because waiting could harm your health. It’s important to check your plan’s formulary (drug list), which will indicate which drugs require prior authorization (noted with “PA”) or step therapy (noted with “ST”), so you know what to expect when your doctor prescribes medication. Understanding these requirements can help you work with your doctor and insurance company to get the medications you need while navigating your plan’s coverage rules, and in some cases, your doctor may be able to select an alternative medication that doesn’t have these restrictions, allowing you to start treatment more quickly without delays.
How do I request an exception to my drug plan formulary?
Requesting an exception to your prescription drug plan formulary is a formal process that allows you to ask your insurance company to cover a medication that is not on their approved drug list or to waive certain restrictions on a formulary drug, and understanding this process can be crucial when your doctor believes a non-formulary medication is medically necessary for your condition. There are several types of formulary exceptions you can request, including asking your plan to cover a drug that’s not on the formulary at all, requesting that a formulary drug be covered at a lower tier to reduce your out-of-pocket costs, or asking the plan to waive utilization management restrictions such as quantity limits, prior authorization requirements, or step therapy protocols that would otherwise apply to your medication. To initiate a formulary exception request, you or your doctor must contact your insurance plan directly, either by phone using the number on your insurance card, through your plan’s online portal, by mail using the plan’s coverage determination request form, or by having your doctor submit the request on your behalf through their provider portal or by fax. The most critical component of any exception request is the supporting statement from your prescriber, which Medicare and most commercial plans require in order to approve an exception, and this statement must explain the medical reasons why the requested drug is necessary for your specific condition. Your doctor’s supporting statement should demonstrate that all alternative drugs on the plan’s formulary would not be as effective for treating your condition, would cause adverse medical effects or side effects that you cannot tolerate, have already been tried without success, or would be medically contraindicated based on your specific health situation, medical history, or other medications you’re taking. For standard exception requests, your plan must make a coverage determination within 72 hours after receiving your doctor’s supporting statement, while expedited or fast-track exception requests must be decided within 24 hours if you or your doctor can demonstrate that waiting for a standard decision could seriously jeopardize your health, life, or ability to regain maximum function. If your formulary exception request is approved, your plan will cover the medication according to the terms of the exception, which might place the drug in a specific tier for coverage purposes and establish how long the exception approval will last before requiring renewal. However, if your exception request is denied, you have the right to appeal that decision through your plan’s appeals process, starting with a redetermination or internal appeal within your insurance company, and if that’s unsuccessful, you can request an independent external review by a qualified independent contractor who will evaluate your case objectively. When preparing your exception request, it’s helpful to gather documentation that supports your case, including your complete medical history related to the condition being treated, records of all medications you’ve tried for this condition and why they didn’t work, documentation of adverse effects or allergies you’ve experienced with formulary alternatives, your doctor’s clinical notes explaining why the requested medication is medically necessary, and any relevant medical literature or clinical guidelines that support using the requested drug for your specific situation. Some insurance plans have specific exception request forms available on their websites or through customer service, while others accept exception requests submitted on any written document including a letter from your doctor, though using your plan’s official form can sometimes speed up the process by ensuring all required information is included. It’s important to note that exception requests are evaluated on a case-by-case basis, and generally, plans will only approve your request if the alternative drugs included on the formulary would not be as effective in treating your condition or would cause you to have adverse medical effects, so having thorough documentation and a well-written physician statement significantly increases your chances of approval. If you need assistance with the formulary exception process, you can contact your insurance plan’s customer service for guidance on how to submit a request, ask your doctor’s office if they have experience submitting exception requests and can help prepare the necessary documentation, or reach out to patient advocacy organizations that may provide support navigating insurance coverage challenges for specific conditions or medications. Remember that while the exception process can take time and requires coordination between you, your doctor, and your insurance company, it provides an important pathway to access medications that may be critical for your health even when they’re not on your plan’s standard formulary, so it’s worth pursuing if your doctor believes a non-formulary medication is truly the best option for managing your condition.
What are the benefits of using mail-order pharmacy for my prescriptions?
Using a mail-order pharmacy for your prescription medications offers numerous advantages that can save you both time and money while improving medication adherence and making it easier to manage chronic health conditions that require long-term maintenance medications. One of the primary benefits of mail-order pharmacy is significant cost savings, as most insurance plans offer lower copayments for 90-day supplies obtained through mail order compared to purchasing the same quantity at retail pharmacies, with some plans charging you only two months’ worth of copays for a three-month supply, effectively giving you one month of medication free. The convenience factor cannot be overstated, as mail-order pharmacies deliver medications directly to your home or preferred address, eliminating the need for trips to the pharmacy, which is particularly valuable if you have mobility challenges, live in a rural area with limited pharmacy access, have a busy schedule that makes pharmacy visits difficult, or simply want to avoid the hassle of picking up prescriptions every month. Research data shows that mail-order pharmacy significantly improves medication adherence, with studies indicating that patients receiving 90-day mail-order prescriptions are approximately 82% adherent to their therapy compared to only 52% adherence when filling traditional 30-day supplies at retail pharmacies, and this improved adherence translates to better health outcomes since taking medications as prescribed is crucial for managing chronic conditions like diabetes, high blood pressure, heart disease, and arthritis. Mail-order pharmacies offer automatic refill programs that proactively manage your prescriptions by tracking when you’re due for refills and shipping medications before you run out, which helps prevent dangerous gaps in therapy that can occur when you forget to refill a prescription or are unable to get to the pharmacy. Despite receiving medications by mail, you still have access to pharmacist consultations through phone, email, or online chat, allowing you to ask questions about your medications, discuss potential side effects or drug interactions, and receive counseling on proper medication use, with many mail-order pharmacies offering extended customer service hours including evenings and weekends. The safety and security of mail-order pharmacy services are well-established, as medications are shipped from licensed pharmacies (not warehouses) in temperature-controlled packaging designed to protect medications from heat, cold, and physical damage during transit, and most mail-order pharmacies require signature confirmation for delivery to ensure medications are received by the intended recipient rather than left unattended. Mail-order pharmacy can be particularly beneficial for specialty medications used to treat complex conditions like cancer, rheumatoid arthritis, multiple sclerosis, or hepatitis C, as specialty mail-order pharmacies often provide comprehensive support services including patient education, injection training, side effect management, copay assistance programs, and coordination with your healthcare providers to optimize treatment outcomes. Setting up mail-order pharmacy service is typically straightforward, requiring you to contact your insurance plan to confirm they offer mail-order benefits and identify which mail-order pharmacy is in their network, provide your prescription information either by having your doctor send prescriptions electronically or by mailing in paper prescriptions, create an account with the mail-order pharmacy either online or by phone, and choose whether you want automatic refills or prefer to approve each refill manually. It’s worth noting that not all medications are suitable for mail order, as controlled substances like opioid pain medications and certain stimulants may have restrictions on mail delivery, and medications needed immediately for acute conditions are better obtained from retail pharmacies, so mail-order pharmacy works best for maintenance medications that you take regularly for chronic conditions. Most mail-order pharmacy services are included in the cost of your insurance plan’s prescription drug benefit without additional fees beyond your regular copayments or coinsurance, making it an accessible option for most people with prescription drug coverage, though you should verify the specific costs with your insurance plan as they can vary. Many mail-order pharmacies integrate with your insurance plan’s mobile app or online portal, allowing you to track shipments, view medication history, set up refill reminders, access medication information, and manage your account conveniently from your smartphone or computer, providing a modern, streamlined experience that gives you greater control over your prescription management. If you’re interested in starting mail-order pharmacy service, contact your insurance company’s customer service or visit their website to learn about your plan’s mail-order pharmacy options, understand any cost differences between retail and mail order, find out which maintenance medications qualify for mail order under your plan, and get instructions on how to transfer existing prescriptions from your retail pharmacy to the mail-order service, as taking these steps can help you begin enjoying the convenience, cost savings, and improved medication adherence that mail-order pharmacy provides.
