Frequently Asked Questions

What is creditable drug coverage?
Creditable coverage is drug coverage that is expected to pay at least as much as Medicare's standard Part D plan. Your plan must notify you annually whether your coverage is creditable.
How much does the penalty cost?
The penalty is 1% of the national base beneficiary premium per uncovered month. For example, 24 months without coverage means a 24% surcharge on your Part D premium.
Can employer drug coverage count as creditable?
Yes. Many employer drug plans are creditable. Your employer or plan is required to tell you whether your coverage is considered creditable.
