  • Tier 1: $5

Another feature is that in the gap coverage phase, Tier 1 and Tier 2 drugs remain at $0 and $2, respectively. 

#8: Anthem MediBlue Rx Plus S5596-060 (PDP)

  • Monthly Premium: $80.60

How Much Does Medicare Part D Cost in Colorado?

The average monthly premium of Part D plans in Colorado is $32, with some being as low as $14.50 and others exceeding $100. Your cost as a whole also depends on your deductible. A plan with no deductible means that you will pay a higher monthly premium, but your medications will cost less. 

The tiers that your medications are in and the number of medicines you use also play a role in your Medicare costs. Every plan has a formulary that shows which prescriptions are covered, and medications are arranged according to tier.

  • Tier 1: Preferred generic drugs
  • Tier 2: Non-preferred generic drugs 
  • Tier 3: Preferred brand-name drugs
  • Tier 4: Non-preferred brand-name drugs
  • Tier 5: Specialty drugs 

Part D plans have three coverage phases that you might go through each year. You pay according to the tier structure in the initial coverage phase until you reach $4,130 in spending. During the gap coverage phase, up to $6,550, you generally pay 25 percent coinsurance. You pay the higher of 5 percent coinsurance or a co-pay of $3.70 (generics) or $9.20 (brand-name) in the catastrophic coverage phase.

One more factor determining the cost of Medicare prescription drug coverage is whether you receive Extra Help. This is a program that gives financial assistance to eligible Medicare beneficiaries

What Is Medicare Part D?

Medicare Part D is prescription drug insurance for those who use Original Medicare for their healthcare coverage. Part D is used in conjunction with Medicare Part A (Hospital Insurance) and Medicare Part B (Medical Insurance) to give you comprehensive insurance coverage. 

With Medicare Part D, you pay a monthly premium to the private insurance company that is your plan provider. Each plan has a deductible that you will need to meet before you enjoy lower-priced medications. 

Medicare Advantage, or Medicare Part C, is an alternative to using Original Medicare. You are always free to change plans during the Open Enrollment Period, which runs from October 15 through December 7. For more details, you can call the Centers for Medicare & Medicaid Services at 1 (800) 633-4227. TTY users can contact 1 (877) 486-2048.



FAQ: Colorado Medicare Part D

Am I eligible for a Medicare Part D plan?

Anyone who qualifies for Medicare is eligible for a prescription drug plan. To qualify for Medicare, you must be 65 and have 10 years of qualifying work. Individuals with end-stage renal disease may qualify earlier. Ideally, you should join during your Initial Enrollment Period, which is the three months before, the month of, and the three months after your 65th birthday. To verify your eligibility, contact your local Social Security office or visit 

Can I add a PDP plan to a Medicare Advantage plan? 

In most cases, no. Prescription drug coverage is included in most Medicare Advantage plans, so it would be pointless to have both. HMO and PPO Medicare Advantage plans cover medications, so if you have one of these and join a PDP plan, you may have to return to Original Medicare. 

The exception to having both a PDP and an MA plan is if your Medicare Advantage plan is a private fee-for-service plan. This type of plan doesn’t offer prescription drugs, so you can add a Part D plan if you have this plan.   

Can I save money and just not join a Part D plan? 

While you might save money short-term, you will find that you are assessed a penalty fee when you do need prescription drug coverage. And this isn’t a one-time fee; you will pay it for as long as you continue in the Medicare program.

If you genuinely do not feel you need a PDP now, choose the lowest-priced one. You will not only avoid the fees later but also have coverage just in case you need it
