Prescription Drug Costs & Benefits

Optimum Diamond Rewards includes enhanced benefit Medicare Part D. Enhanced benefits offer greater coverage than basic, typically providing lower cost-sharing, broader drug coverage, and additional benefits, such as covering drugs not included in the standard formulary. These plans usually have higher premiums due to the extra coverage and flexibility they provide, but they cover a larger percentage of overall drug costs.

As of 2023, approximately 75% of people on Medicare are enrolled in enhanced plans.

Prescription Drug Premium with Extra Help

Extra Help is a Social Security program that helps people with limited income and resources lower or cut Part D costs. The following table outlines premium assistance details with Extra Help.

Health Plan Compatibility

Medicare Advantage Special Need Plans are not compatible with most other forms of health insurance. If you have Medicare Part A and/or Medicare Part B and join a SNP plan, you will be disenrolled from Original Medicare. You cannot simultaneously enroll in an SNP plan and Medicare Supplement Insurance.

With a D-SNP, members retain their existing Medicaid plan and benefits. Veterans who have VA Health Benefits may also be able to receive care at their local VA hospital.
