Prescription Advantage Eligibility 2026: Income Limits and How to Enroll
Massachusetts runs its own prescription drug assistance program on top of Medicare Part D, and the income ceiling is far higher than most people expect. Prescription Advantage covers residents with household income up to 500% of the federal poverty level — roughly $6,650 per month for a single person in 2026. There is no asset test.
Who Qualifies
Prescription Advantage eligibility has two paths:
Age-based: Massachusetts residents aged 65 or older who are enrolled in a Medicare Part D plan (or a creditable drug plan) and meet the income limits. This is the path most families use.
Disability-based: Massachusetts residents under 65 who receive SSDI or meet Title XVI disability standards, work no more than 40 hours per month, and meet the same income limits.
No asset test applies to either path. Savings accounts, retirement funds, home equity, and vehicles are not counted.
2026 Income Tiers
Prescription Advantage sorts enrollees into four income categories, each with different levels of copay assistance:
Category 1 (lowest income) — Eliminates Part D plan deductibles entirely. Pays secondary copays down to a fixed schedule. Full enrollment fee waiver.
Category 2 (low-to-moderate income) — Provides secondary copay assistance after the plan deductible. Sliding-scale copay limits based on income.
Category 3 (moderate income) — Secondary copay protection and gap coverage assistance. Grants a one-time Special Enrollment Period outside Annual Enrollment to change Medicare drug coverage.
Category 4 (upper moderate, up to 500% FPL) — Catastrophic drug protection. Grants the same one-time Special Enrollment Period outside Annual Enrollment for plan switching.
The exact dollar thresholds for each category update annually based on federal poverty level figures published each March. The Executive Office of Aging & Independence publishes current limits on mass.gov/prescription-drug-assistance.
How Prescription Advantage Works with Part D and Extra Help
Prescription Advantage is a secondary payer. It sits behind Medicare Part D and pays what Part D does not cover — deductible gaps, copay overages, and specialty drug costs.
Here is the layering:
- Medicare Part D pays first, covering drugs on the plan's formulary according to its benefit structure
- Extra Help (if your parent qualifies) reduces Part D copays and eliminates the deductible
- Prescription Advantage pays secondary copays on top of whatever Part D and Extra Help leave
If your parent qualifies for a Medicare Savings Program (QMB, SLMB, or QI), they automatically get full Extra Help. For a parent qualifying through MSP alone, that means a $0 Part D deductible and 2026 copays capped at $5.10 for generic or preferred multi-source drugs and $12.65 for other drugs. Prescription Advantage then provides additional secondary coverage on top of that.
The 2026 Part D redesign caps total out-of-pocket drug costs at $2,100 per year. Prescription Advantage helps by paying secondary copays upfront, which slows the rate at which your parent accumulates out-of-pocket spending toward that cap. Once the $2,100 threshold is reached, Part D covers 100% of covered drug costs for the rest of the year.

The Special Enrollment Period Benefit
Beyond direct copay assistance, Prescription Advantage enrollment gives your parent a Special Enrollment Period (SEP) for Medicare Part D. This lets them join, switch, or drop a Part D prescription drug plan — or a Medicare Advantage plan that includes drug coverage — one time per year outside the standard October-December Annual Enrollment Period.
This is valuable when a Part D plan changes its formulary or raises copays mid-year. Without Prescription Advantage, your parent would be locked into the plan until the next enrollment window.
How to Enroll
Applications go to the Executive Office of Aging & Independence (the agency formerly known as Elder Affairs):
- Phone: 1-800-243-4636 (TTY: 1-877-610-0241)
- Mail: Prescription Advantage Program, PO Box 15153, Worcester, MA 01615-0153
- Online: mass.gov/prescription-drug-assistance
The application requires proof of household income and Medicare enrollment. Processing is handled by the Executive Office of Aging & Independence, not MassHealth — the two are separate agencies.
If Prescription Advantage denies the application or places your parent in the wrong income category, the appeal goes to the Executive Office of Aging & Independence's administrative review officers. The MassHealth Board of Hearings has no jurisdiction over Prescription Advantage decisions.
One Application, Three Layers of Help
If your parent's income qualifies them for a Medicare Savings Program, applying for MSP through MassHealth is the single most efficient step: it triggers automatic Extra Help, which in turn coordinates with Prescription Advantage. The Massachusetts Medicare Savings Programs guide covers how all three layers stack and includes the application steps for each program.
