Medicare Part D Drug Plans in Chandler, AZ

What to know before you choose

For CY2027 the CMS Landscape lists 9 stand-alone Part D plans in Arizona, with monthly premiums from $5.30 to $191.50 (CY2027, CMS Landscape). Premium is only one piece. Each plan has its own drug list (formulary), its own tiers, its own deductible and its own preferred pharmacies. Two plans with similar premiums can be hundreds of dollars apart once your prescriptions are priced.

Since 2025 there is a yearly cap on what you pay out of pocket for covered Part D drugs. In 2026 that cap is $2,100; once you reach it, covered drugs cost you $0 for the rest of the year. For 2027 CMS has set the cap at $2,400 and the most a plan's deductible can be at $700 (CMS CY2027 Rate Announcement). The cap helps people with expensive medicines most, but how quickly you reach it, and what you pay on the way, still depends on the plan.

A worked example, as an illustration only. Suppose your covered prescriptions are expensive enough to reach the cap in 2027. You pay up to $700 first if your plan uses the full deductible, then your tier copays or coinsurance until your out-of-pocket spending reaches $2,400, then $0 for covered drugs for the rest of the year. The same year under the 2026 rules would have stopped at $2,100, so the most you can spend on covered drugs rises by $300. Your plan premium is paid on top of the cap, and drugs not on the plan's drug list do not count toward it.

Timing matters too. If you go 63 days or more in a row without Part D or other creditable drug coverage after your Initial Enrollment Period, Medicare can add a late enrollment penalty to your premium for as long as you have Part D. If you are working past 65 with employer coverage, Viola helps you confirm whether that coverage counts as creditable so you do not get caught by it later.

Here is how that penalty is figured, as a worked example. Medicare multiplies 1% of the national base beneficiary premium by the number of full months you went without creditable coverage, and rounds to the nearest 10 cents (Medicare.gov, Avoid late enrollment penalties). The base premium is $38.99 in 2026 and $41.33 in 2027 (CMS). Someone who went 20 months without coverage would add $7.80 a month in 2026 and $8.30 a month in 2027, and the amount is recalculated each year for as long as they have Part D.

Viola's process is simple. You give her the name, dose and how often you take each medicine, plus the pharmacy you like. She prices them across the plans she offers, flags anything that needs prior authorization or step therapy, and shows you the estimated total for the year, premium plus drug costs. If your income is limited she checks whether you may qualify for Extra Help, the Social Security program that lowers Part D costs, or for an Arizona Medicare Savings Program through AHCCCS.

Drug lists change every year, and new prescriptions change the math. That is why she reruns your drugs every Annual Enrollment Period, October 15 to December 7, 2026 for 2027 coverage, and why you can call her mid-year when a pharmacy tells you something is no longer covered.
