What can members do, and by when?
If you live in Alameda (CA), San Francisco (CA), San Mateo (CA), Santa Clara (CA)
- If you do nothing
- You are moved into Central Health Harmony 031 on January 1, 2027.
- October 15 to December 7, 2026
- Open enrollment: choose another Medicare Advantage plan, or Original Medicare with a drug plan, instead.
If you live in Fresno (CA), Los Angeles (CA), Madera (CA), Marin (CA), Merced (CA), Orange (CA), Placer (CA), Riverside (CA), Sacramento (CA), San Bernardino (CA), San Diego (CA), San Joaquin (CA), San Luis Obispo (CA), Stanislaus (CA), Ventura (CA), Yolo (CA)
- Your coverage
- Ends December 31, 2026: Central Health Harmony 031 is not sold where you live.
- October 15 to December 7, 2026
- Open enrollment: join another Medicare Advantage plan, or Original Medicare with a drug plan. Coverage starts January 1, 2027.
- December 8, 2026 to the end of February 2027
- A special enrollment period because the plan is leaving: you can still join a plan, but coverage starts the first day of the month after you join, so choose by December 31 to have no gap.
- If you do nothing
- You are enrolled in Original Medicare when the plan ends, without a drug plan unless you join one (with Extra Help or full Medicaid, Medicare enrolls you in one).
- Without a drug plan
- Going 63 days or more in a row without drug coverage can mean a late enrollment penalty if you join a drug plan later; joining by the end of February keeps a January and February gap under 63 days, waiting longer does not.
