Get to know AARP Medicare Supplement Plans

AARP® Medicare Supplement Plans from UnitedHealthcare are health insurance plans designed to supplement Original Medicare. They help pay some of the health care costs that Original Medicare does not cover, based on the specific benefits provided under the insured member’s plan, including copays, coinsurance and deductibles.

Understanding EZ Claim Pay

Through EZ Claim Pay, insured members choose to have UnitedHealthcare pay their Medicare Part B deductible responsibility amount on their behalf when Medicare applies all or part of their deductible to eligible claims.

If an insured member is enrolled in the EZ Claim Pay service:

You do not need to bill them directly for their Medicare Part B deductible amount

We’ll pay you the appropriate deductible amount for claims we receive

We’ll send payments by check, separate from other claim reimbursement. Please make sure we have your current pay to/mailing address information on record.

We’ll include the claim number and other claim-related information with the check so you can correctly apply the EZ Claim Pay payments to the insured member’s responsibility

Insured members should inform you that they use the EZ Claim Pay service

There is no change to how you submit claims with this service

For questions about EZ Claim Pay, please call 877-223-1628 7 a.m.–11 p.m. ET, Monday–Friday and 9 a.m.–5 p.m. ET on Saturday.
