Medicare Prescription Payment Plan


The Medicare Prescription Payment Plan is a new payment option in the prescription drug law that works with your current drug coverage to help you manage your out-of-pocket Medicare Part D drug costs by spreading them across the calendar year (January-December). Starting in 2025, anyone with a Medicare drug plan or Medicare health plan with drug coverage (like a Medicare Advantage Plan with drug coverage) can use this payment option. PacificSource Medicare offers this payment option and participation is voluntary.

If you select this payment option, each month you'll continue to pay your plan premium (if you have one), and you'll get a separate bill from us to pay for your prescription drugs (instead of paying the pharmacy). There's no cost to participate in the Medicare Prescription Payment Plan.

What to know before participating

How does it work?

When you fill a prescription for a covered Part D drug, you won't pay your pharmacy (including mail order and specialty pharmacies). Instead, you'll get a bill each month from your health plan.

Even though you won't pay for your drugs at the pharmacy, you're still responsible for the costs. If you want to know what your drug will cost before you take it home, call your plan or ask the pharmacist.

This payment option might help you manage your monthly expenses, but it doesn't save you money or lower your drug costs.

How is my monthly bill calculated?

Your monthly bill is based on what you would have paid for any prescriptions you get, plus your previous month's balance, divided by the number of months left in the year. All plans use the same formula to calculate your monthly payments. See examples below.

Your payments might change every month, so you might not know what your exact bill will be ahead of time. Future payments might increase when you fill a new prescription (or refill an existing prescription) because as new out-of-pocket costs get added to your monthly payment, there are fewer months left in the year to spread out your remaining payments.

In a single calendar year (January – December), you'll never pay more than:
  • The total amount you would have paid out of pocket to the pharmacy if you weren't participating in this payment option.
  • The Medicare drug coverage annual out-of-pocket maximum ($2,000 in 2025).

The prescription drug law caps your out-of-pocket drug costs at $2,000 in 2025. This is true for everyone with Medicare drug coverage, even if you don't participate in the Medicare Prescription Payment Plan.

Will this help me?

It depends on your situation. Remember, this payment option might help you manage your monthly expenses, but it doesn't save you money or lower your drug costs. You're most likely to benefit from participating in the Medicare Prescription Payment Plan if you have high drug costs earlier in the calendar year. Although you can start participating in this payment option at any time in the year, starting earlier in the year (like before September), gives you more months to spread out your drug costs. Go to Medicare.gov/prescription-payment-plan/will-this-help-me to answer a few questions, and find out if you're likely to benefit from this payment option.

This payment option may not be the best choice for you if:
  • Your yearly drug costs are low.
  • Your drug costs are the same each month.
  • You're considering signing up for the payment option late in the calendar year (after September).
  • You don't want to change how you pay for your drugs.
  • You get or are eligible for Extra Help from Medicare.
  • You get or are eligible for a Medicare Savings Program.
  • You get help paying for your drugs from other organizations, like a State Pharmaceutical Assistance Program (SPAP), a coupon program, or other health coverage.

You can use this payment calculator tool by entering your monthly prescription costs to see if enrolling in this program may be a good option for you.

Remember, this payment option may not be the best choice for you if you sign up late in the calendar year (after September). This is because as new out-of-pocket drug costs are added to your monthly payment, there are fewer months left in the year to spread out your payments.

What to know if I'm participating

What happens after I sign up?

Once your health or drug plan reviews your participation request, they'll send you a letter confirming your participation in the Medicare Prescription Payment Plan. Then:
  1. When you get a prescription for a drug covered by Part D, your plan will automatically let the pharmacy know that you're participating in this payment option, and you won't pay the pharmacy for the prescription.

    Even though you won't pay for your drugs at the pharmacy, you're still responsible for the costs. If you want to know what your drug will cost before you take it home, call your plan or ask the pharmacist.

  2. Each month, your plan will send you a bill with the amount you owe for your prescriptions, when it's due, and information on how to make a payment. You'll get a separate bill for your monthly plan premium (if you have one).

  3. There may be a time when you have an urgent need for a prescription with a high cost, and cannot wait until your election request into the program is processed, so you must purchase the prescription at the pharmacy immediately. In this scenario you may meet the requirements for reimbursement if all of the following conditions are met:
    1. You have paid for an urgent prescription out of pocket before your election into the program was received and processed
    2. You believe that any delay in filling the prescription, due to the 24 hour timeframe required to process your request to opt into the program, may seriously jeopardize your life, health or ability to regain maximum function; and
    3. You request retroactive election with 72 hours of the date and time the urgent prescription claim was billed to the health plan

How do I pay my bill?

After your health or drug plan approves your participation in the Medicare Prescription Payment Plan, you'll get a letter from your plan with information about how to pay your bill.

What happens if I don't pay my bill?

You'll get a reminder from your health or drug plan if you miss a payment. If you don't pay your bill by the date listed in that reminder, you'll be removed from the Medicare Prescription Payment Plan. You're required to pay the amount you owe, but you won't pay any interest or fees, even if your payment is late. You can choose to pay that amount all at once or be billed monthly. If you're removed from the Medicare Prescription Payment Plan, you'll still be enrolled in your Medicare health or drug plan.

Always pay your health or drug plan monthly premium first (if you have one), so you don't lose your drug coverage. If you're concerned about paying both your monthly plan premium and Medicare Prescription Payment Plan bills, see below for information about programs that can help lower your costs.

Call customer service if you think we have made a mistake about your Medicare Prescription Payment Plan bill. If you think we have made a mistake, you have the right to follow the grievance process found in your Member Handbook or Evidence of Coverage. Contact customer service at 888-863-3637, TTY or email newappeal@pacificsource.com.

How do I leave?

You can leave the Medicare Prescription Payment Plan at any time by visiting InTouch.PacificSource.com/Members. or contacting customer service. Leaving won't affect your Medicare drug coverage and other Medicare benefits. Keep in mind:
  • If you still owe a balance, you're required to pay the amount you owe, even though you're no longer participating in this payment option.
  • You can choose to pay your balance all at once or be billed monthly.
  • You'll pay the pharmacy directly for new out-of-pocket drug costs after you leave the Medicare Prescription Payment Plan.

What happens if I change health or drug plans?

If you leave your current plan, or change to a new Medicare drug plan or Medicare health plan with drug coverage (like a Medicare Advantage Plan with drug coverage), your participation in the Medicare Prescription Payment Plan will end.

Contact your new plan if you'd like to participate in the Medicare Prescription Payment Plan again.

Examples of how a monthly bill is calculated

Example 1:

You take several high-cost drugs that have a total out-of-pocket cost of $500 each month. In January 2025, you join the Medicare Prescription Payment Plan through your Medicare drug plan or Medicare health plan with drug coverage.

We calculate your first month's bill in the Medicare Prescription Payment Plan differently than your bill for the rest of the months in the year:

  • First, we figure out your “maximum possible payment” for the first month:
    $2,000 [annual out-of-pocket maximum]
    – $0 [no out-of-pocket costs before using this payment option]
    = $2,000
    12 [remaining months in the year] = $166.67 [your "maximum possible payment" for the first month]
  • Then, we figure out what you'll pay for January:
    • Compare your total out-of-pocket costs for January ($500) to the “maximum possible payment” we just calculated: $166.67.
    • Your plan will bill you the lesser of the two amounts. So, you'll pay $166.67 for the month of January.
    • You have a remaining balance of $333.33 ($500-$166.67).

For February and the rest of the months left in the year, we calculate your payment differently:

$333.33 [remaining balance] + $500 [new costs]
= $833.33
11 [remaining months in the year] = $75.76 [your payment for February]

We'll calculate your March payment like we did for February:

$757.57 [remaining balance] + $500 [new costs]
= $1257.57
10 [remaining months in the year] = $125.76 [your payment for March]

In April, when you refill your prescriptions again, you’ll reach the annual out-of-pocket maximum for the year ($2,000 in 2025). You’ll continue to pay what you already owe and get your prescription(s), but after April you won’t add any new out-of-pocket costs for the rest of the year.

$1131.81 [remaining balance] + $500 [new costs]
= $1631.81
9 [remaining months in the year] = $181.31 [your payment for April and all remaining months in the year]
Even though your payment varies each month, by the end of the year, you’ll never pay more than:
  • The total amount you would have paid out-of-pocket.
  • The total annual out-of-pocket maximum ($2,000 in 2025).
Remember, this is just your monthly payment for your out-of-pocket drug costs. You still need to pay your health or drug plan’s premium (if you have one) each month.


Example 1: Start participating in January with high drug costs early in the year
Month Your drug costs (without this payment option) Your monthly payment (with this payment option) Notes
January $500 $166.67 This is when you started participating in this payment option. Remember, your first month's bill is based on the “maximum possible payment” calculation. We calculate your bill for the rest of the months in the year differently.
February $500 $75.76
March $500 $125.76
April $500 $181.31 This month you reached the annual out-of-pocket maximum ($2,000 in 2025). You'll have no new out-of-pocket drug costs for the rest of the year.
May $0.00 $181.31* *You'll still get your $500 drugs each month, but because you've reached the annual out-of-pocket maximum, you won't add any new out-of-pocket costs for the rest of the year. You'll continue to pay what you already owe.
June $0.00 $181.31*
July $0.00 $181.31*
August $0.00 $181.31*
September $0.00
October $0.00 $181.31*
November $0.00 $181.31*
December $0.00 $181.31*
Total $2,000.00 $2,000.00 You'll pay the same total amount for the year, even if you don't use this payment option.

If you're concerned about paying $500 each month from January to April, this payment option will help you manage your costs. If you prefer to pay $500 each month for 4 months and then pay $0 for the rest of the year, this payment option might not be right for you. Contact your health or drug plan for personalized help.


Example 2:

You take several drugs that have a total out-of-pocket cost of $80 each month. In January 2025, you join the Medicare Prescription Payment Plan through your Medicare drug plan or Medicare health plan with drug coverage.

We calculate your first month's bill in the Medicare Prescription Payment Plan differently than your bill for the rest of the months in the year:

  • First, we figure out your “maximum possible payment” for the first month:
    $2,000 [annual out-of-pocket maximum]
    – $0 [no out-of-pocket costs before using this payment option]
    = $2,000
    12 [remaining months in the year] = $166.67 [your "maximum possible payment" for the first month]
  • Then, we figure out what you'll pay for January:
    • Compare your total out-of-pocket costs for January ($80) to the “maximum possible payment” we just calculated: $166.67.
    • Your plan will bill you the lesser of the two amounts. So, you'll pay $80 for the month of January.
    • You have a remaining balance of $0.

For February and the rest of the months left in the year, we calculate your payment differently:

$0 [remaining balance] + $80 [new costs]
= $80
11 [remaining months in the year] = $7.27 [your payment for February]

We'll calculate your March payment like we did for February:

$72.73 [remaining balance] + $80 [new costs]
= $152.73
10 [remaining months in the year] = $15.27 [your payment for March]
Even though your payment varies each month, by the end of the year, you’ll never pay more than:
  • The total amount you would have paid out-of-pocket.
  • The total annual out-of-pocket maximum ($2,000 in 2025).
Remember, this is just your monthly payment for your out-of-pocket drug costs. You still need to pay your health or drug plan’s premium (if you have one) each month.


Example 2: Start participating in January with consistent costs throughout the year
Month Your drug costs (without this payment option) Your monthly payment (with this payment option) Notes
January $80.00 $80.00 This is when you started participating in this payment option. Remember, your first month's bill is based on the “maximum possible payment” calculation. We calculate your bill for the rest of the months in the year differently.
February $80.00 $7.27
March $80.00 $15.27
April $80.00 $24.16
May $80.00 $34.16
June $80.00 $45.59
July $80.00 $58.93
August $80.00 $74.92
September $80.00 $94.93
October $80.00 $121.59
November $0.00 $161.59
December $80.00 $241.59
Total $960.00 $960.00 You'll pay the same total amount for the year, even if you don't use this payment option.

Depending on your specific circumstances, you might not benefit from using this payment option due to the higher payments that start in September. Contact your health or drug plan for personalized help.


Example 3:

You pay $4 every month in out-of-pocket costs for a prescription you use regularly. In April 2025, you need a new one-time prescription that costs $613, so your total out-of-pocket costs in April are $617. That same month, before you fill your prescriptions, you decide to participate in the Medicare Prescription Payment Plan through your Medicare drug plan or Medicare health plan with drug coverage.

We calculate your first month’s bill in the Medicare Prescription Payment Plan differently than your bill for the rest of the months in the year:

  • First, we figure out your “maximum possible payment” for the first month:
    $2,000 [annual out-of-pocket maximum]
    – $12 [no out-of-pocket costs before using this payment option]
    = $1,988
    9 [remaining months in the year] = $220.89 [your "maximum possible payment" for the first month]
  • Then, we figure out what you'll pay for April:
    • Compare your total out-of-pocket costs for April ($617) to the “maximum possible payment” we just calculated: $220.89.
    • Your plan will bill you the lesser of the two amounts. So, you'll pay $220.89 for the month of April.
    • You have a remaining balance of $396.11 ($617-$220.89).

For May and the rest of the months left in the year, we calculate your payment differently:

$396.11 [remaining balance] + $4 [new costs]
= $400.11
8 [remaining months in the year] = $50.01 [your payment for May]

Your payments will vary throughout the year. That's because you're adding drug costs during the year, but you have fewer months left in the year to spread your payments across.

By the end of the year, you’ll never pay more than:
  • The total amount you would have paid out-of-pocket.
  • The total annual out-of-pocket maximum ($2,000 in 2025).
Remember, this is just your monthly payment for your out-of-pocket drug costs. You still need to pay your health or drug plan’s premium (if you have one) each month.


Example 3: Start participating in April with varying costs throughout the year
Month Your drug costs (without this payment option) Your monthly payment (with this payment option) Notes
January $4.00 $4.00* * You made these payments directly to the pharmacy before you started participating in the Medicare Prescription Payment Plan.
February $4.00 $4.00*
March $4.00 $4.00*
April $617.00 $220.89 This is when you started using this payment option. Remember, your first month’s bill is based on the “maximum possible payment” calculation. We calculate your bill for the rest of the months in the year differently.
May $4.00 $50.01
June $4.00 $50.59
July $124.71 $71.25 This month, you need a drug that’s $120, in addition to your $4 drug. Following the same formula we used in May, your payments increase because you’re adding drug costs during the year, but you have fewer months left in the year to spread your payments across.
August $4.00 $72.05
September $4.00 $73.05
October $124.00 $114.39 This month, you need a drug that’s $120, in addition to your $4 drug. Following the same formula we used in May, your payments increase because you’re adding drug costs during the year, but you have fewer months left in the year to spread your payments across.
November $4.00 $116.39*
December $4.00 $120.38
Total $901.00 $901.00 You'll pay the same total amount for the year, even if you don't use this payment option.

If you’re concerned about paying $617 in April, this payment option will help you spread your costs across monthly payments that vary throughout the year. If you’re concerned about higher payments later in the year, this payment option might not be right for you. Contact your health or drug plan for personalized help.
