- The new cards are for original Medicare plans and do not apply to Medicare Advantage plans.
- They do not include Social Security numbers (SSNs).
- Cards will have a new Medicare beneficiary identifier (MBI) that replaces the SSN-based health insurance claim numbers (HICNs) used for Medicare transactions, such as billing and claim status.
- Treat the new MBI like personal health information.
