Medicare Part D

Medicare Part D in Spokane

Medicare Part D helps pay for outpatient prescription drugs. Coverage is available through private insurance companies approved by Medicare in two main ways:

• A standalone Part D prescription drug plan used with Original Medicare
• Drug coverage built into many Medicare Advantage plans

The lowest-premium plan is not automatically the lowest-cost plan. The right comparison starts with your exact medications, doses, quantities, pharmacies, and preferred way to fill prescriptions. Formularies, drug tiers, pharmacy contracts, deductibles, copays, coinsurance, and restrictions can differ from one plan to another and can change each calendar year.

This guide explains the decision process. It does not recommend a specific plan, guarantee that a medication will be covered, or replace the plan's current formulary and Evidence of Coverage.

What Part D covers

Every Medicare drug plan must cover a broad range of prescription drugs, including protected classes required by Medicare. Each plan maintains its own formulary, or covered-drug list.

A formulary usually places drugs into cost-sharing tiers. A lower tier may have a smaller copay, while a higher tier may have a larger copay or coinsurance. A drug can also have coverage rules such as:

• Prior authorization: the plan requires approval before covering the prescription
• Step therapy: the plan generally requires trying another covered drug first
• Quantity limits: the plan limits how much is covered at one time
• Specialty-pharmacy requirements: certain drugs must be filled through a designated pharmacy
• Network restrictions: a pharmacy may be out of network or may not offer the plan's preferred pricing

Two plans can cover the same drug but produce very different annual costs because the drug is on a different tier, the pharmacy has a different network status, or one plan applies a deductible or restriction that another does not.

Standalone Part D versus Medicare Advantage drug coverage

If you use Original Medicare, you can add a standalone Part D plan. A Medicare Supplement policy does not include outpatient prescription drug coverage, so people using Medigap commonly pair it with a standalone Part D plan.

Many Medicare Advantage plans include prescription drug coverage. If you enroll in a Medicare Advantage plan with drug coverage, you generally should not add a separate standalone Part D plan. Doing so can cause disenrollment from the Medicare Advantage plan in many situations.

Some Medicare Advantage plans do not include drug coverage. Before choosing one, confirm whether you are allowed to add a separate Part D plan and whether that arrangement fits the plan type.

The 2026 Part D cost structure

Your actual cost depends on the plan and the drugs you fill. A Part D plan may charge:

• A monthly premium
• An income-related adjustment paid in addition to the plan premium for some higher-income beneficiaries
• An annual deductible
• Copays or coinsurance
• Different amounts at standard, preferred, out-of-network, mail-order, or specialty pharmacies

For 2026, no Medicare drug plan may have a deductible higher than $615, although a plan may use a lower deductible or no deductible. After the deductible, the plan's copays and coinsurance apply according to its benefit design.

Under the standard 2026 Part D benefit, covered-drug out-of-pocket spending is capped at $2,100 for the calendar year. After the amount that counts toward this threshold reaches $2,100, the member pays $0 out of pocket for covered Part D drugs for the rest of that calendar year.

The $2,100 cap does not mean every prescription is covered, and it is not a cap on premiums or on amounts paid for drugs that the plan does not cover. Confirm that each drug is on the formulary and follow the plan's coverage rules.

Part D also includes other federal protections. Recommended adult vaccines covered under Part D have no cost sharing. Covered insulin is subject to a monthly cost-sharing limit under federal rules. Verify the exact amount for the specific product and plan.

The Medicare Prescription Payment Plan

Every Medicare drug plan offers the Medicare Prescription Payment Plan. It is a voluntary payment option that can spread out-of-pocket costs for covered prescriptions across the remaining months of the calendar year.

It may help with cash flow when high drug costs occur early in the year, but it:

• Does not reduce the total cost of the prescriptions
• Does not reduce the plan premium
• Does not change which drugs the plan covers
• Does not replace Extra Help or another assistance program
• Can produce changing monthly bills as new prescription costs are added

People who join continue paying the plan premium separately. Instead of paying the covered out-of-pocket amount at the pharmacy, the person receives bills from the plan. Review the payment schedule before enrolling, especially later in the year when fewer months remain to spread the balance.

Why the pharmacy matters

Part D plans contract with pharmacy networks. A pharmacy may be:

• Preferred in network
• Standard in network
• Out of network
• Mail order
• Specialty

A familiar pharmacy can be covered but still cost more than a preferred pharmacy. Compare at least the pharmacies you would realistically use. Include local Spokane locations, mail order if desired, and any specialty pharmacy required for a particular drug.

Do not choose a pharmacy based only on the price of one prescription. The best pharmacy for one medication may not produce the lowest total cost for the entire list.

Build a complete medication list before comparing

For each prescription, record:

1. Exact drug name
2. Strength, such as 10 mg
3. Form, such as tablet, capsule, inhaler, pen, patch, cream, or solution
4. Quantity filled each time
5. How often it is filled
6. Whether the prescription must be brand name
7. Preferred local pharmacy
8. Whether mail order is acceptable

Include expensive medications, occasional prescriptions, insulin, inhalers, injectables, creams, eye drops, and drugs filled through specialty pharmacies. A missing dose or quantity can materially change an estimate.

Also separate drugs usually covered under Part B from drugs typically covered under Part D. Some physician-administered drugs, infusion drugs, durable-medical-equipment drugs, and vaccines may be processed under Part B instead. The setting and method of administration can matter.

A practical plan-comparison method

Use Medicare Plan Compare or another Medicare-approved comparison system with the complete medication list. For each plan, review:

• Estimated annual prescription cost
• Monthly premium
• Deductible and whether it applies to every tier
• Cost for every medication
• Pharmacy network and preferred status
• Mail-order pricing
• Formulary tier
• Prior authorization, step therapy, and quantity limits
• Whether a medication is excluded
• Star rating and customer-service considerations
• Whether drug coverage is standalone or bundled with Medicare Advantage

Look at the estimated total annual cost, not only the premium and not only the January price. A plan with a higher premium can be less expensive overall if it covers the medications more favorably.

Estimates are useful but are not guarantees. Prices can change when a prescription changes, a drug is filled at a different pharmacy, the member enters another coverage stage, or the plan processes a claim differently based on current information.

What can change each year

Part D plans can change:

• Premiums and deductibles
• Formularies
• Drug tiers
• Copays and coinsurance
• Pharmacy networks and preferred-pharmacy arrangements
• Prior authorization, step therapy, and quantity limits
• Mail-order and specialty-pharmacy rules

Read the plan's Annual Notice of Change and Evidence of Coverage. Even if the plan name stays the same, do not assume the prescription coverage will be identical next year.

A medication list should be reviewed every fall before comparing plans. Update changes made during the year and verify that discontinued medications have been removed.

When can you enroll or change plans?

Your first Part D enrollment opportunity usually connects to your Initial Enrollment Period for Medicare. People may also enroll or change plans during other periods, including:

• Medicare Open Enrollment, October 15 through December 7: join, switch, or drop Part D coverage for the following January 1
• Medicare Advantage Open Enrollment, January 1 through March 31: people already in Medicare Advantage may make one permitted plan change or return to Original Medicare and join a standalone Part D plan
• Special Enrollment Periods: certain moves, coverage losses, Medicaid or Extra Help changes, institutional care, and other qualifying events may create a separate opportunity

The available action and deadline depend on the event. Confirm eligibility before ending current coverage.

Creditable coverage and the late-enrollment penalty

Other prescription coverage is creditable when it is expected to pay, on average, at least as much as standard Medicare drug coverage. Employer and union plans generally send an annual notice stating whether their coverage is creditable. Keep those notices.

A Part D late-enrollment penalty may apply after a period of 63 consecutive days or more without Part D or other creditable prescription coverage once the Initial Enrollment Period has ended. The penalty is generally added to the monthly Part D premium for as long as the person has Part D.

The penalty calculation uses 1% of the national base beneficiary premium for each full uncovered month. Because that base amount can change, the penalty can also change. People receiving Extra Help do not pay the late-enrollment penalty while they qualify.

Do not assume that a discount card, cash-price program, COBRA drug benefit, retiree plan, VA coverage, or another arrangement is creditable. Obtain the official notice or confirmation from the coverage source.

Extra Help and other assistance

Extra Help is a Medicare program for people with limited income and resources. It can reduce Part D premiums, deductibles, and prescription cost sharing. Some people qualify automatically through Medicaid, a Medicare Savings Program, or Supplemental Security Income; others can apply through Social Security.

In 2026, qualifying for Extra Help can provide a $0 plan premium and $0 deductible for a plan meeting program rules, with prescription copays limited by the beneficiary's assistance level. Eligibility and amounts can change, so use Medicare's current figures when applying.

Washington residents can also contact the Statewide Health Insurance Benefits Advisors program, known as SHIBA, for free, unbiased Medicare counseling. A licensed independent insurance agency can compare the plans it represents, while Medicare and SHIBA can provide information about all available options.

If a drug is not covered or is too expensive

Do not stop taking a prescribed medication without speaking with the prescriber. Options may include:

1. Confirming the correct drug, strength, quantity, pharmacy, and claim information
2. Asking whether a covered generic or therapeutic alternative is medically appropriate
3. Requesting a formulary exception
4. Requesting an exception to a tier or coverage rule when permitted
5. Filing an appeal after an adverse coverage decision
6. Checking Extra Help, a manufacturer assistance program, or another eligible assistance source
7. Comparing pharmacy pricing while understanding that paying outside the Part D plan may not count toward the deductible or out-of-pocket cap

The prescriber may need to document why the requested drug is medically necessary. Keep denial notices, receipts, names, dates, and confirmation numbers.

Before enrolling in a Part D plan

Use this checklist:

• Confirm Medicare eligibility and the desired effective date
• Enter every current prescription accurately
• Compare more than one realistic pharmacy
• Review total annual cost, not premium alone
• Check each drug's formulary tier
• Review prior authorization, step therapy, and quantity limits
• Verify any specialty-pharmacy requirement
• Confirm whether current coverage is creditable
• Check eligibility for Extra Help
• Understand the Medicare Prescription Payment Plan if high early-year costs are expected
• Save the enrollment confirmation
• Do not cancel existing coverage until the new plan and effective date are confirmed
