The IAM–Humana arrangement is a union-related group Medicare option, not a separate insurance company called “IAM-Humana.” Start with IAM's official Retiree and Medicare Resource Center to confirm whether you and eligible family members can participate.

Use the group-specific information
IAM publishes resources for its group Medicare program. Do not substitute a general Humana retail-plan brochure: eligibility, enrollment channels, contributions and benefits may differ. Ask for the packet for the correct coverage year and your member category.
| Question | Who can clarify |
|---|---|
| Union or retiree eligibility | The official IAM program resource or designated administrator. |
| Plan benefits and claims | The insurer identified in the group documents. |
| Medicare enrollment status | Medicare or Social Security, as appropriate. |
| Family-member enrollment | The group administrator and current enrollment instructions. |
Verify provider access
A group PPO may have different terms from an individual PPO. Ask whether your doctor accepts the exact arrangement and what happens for care outside the usual network. Do not turn a general description of nationwide access into a promise that every professional will accept the plan.
Review other benefits before changing
Contact the responsible benefits office before replacing employer or union coverage. Ask about effects on dependents, contributions and any right to return. A new individual policy does not automatically preserve those arrangements.
Keep enrollment records
- Confirm the current eligibility category and required Medicare enrollment.
- Use the official group application instructions.
- Check whether each family member needs a separate application.
- Save acceptance, premium information and the effective date.
An agent who explains individual Medicare options is not necessarily authorized to administer this union program. Use the designated group contact for binding answers about participation and enrollment.
