Best Time to Review Your Medicare Plan in California is an educational guide for older adults, caregivers, and families who want to review Medicare coverage carefully before making a change. A Medicare plan review is not only for people who are unhappy with coverage. It is a yearly safety check. Costs, benefits, drug formularies, pharmacies, provider networks, and plan rules can change. A senior's health needs can change too.
For seniors in Los Angeles County and across California, even a small change can matter. A new specialist, different medication, hospital discharge, pharmacy change, transportation problem, or caregiver concern can turn a plan that once worked into a plan that needs a closer look.
Quick answer
The best time to review a Medicare plan is before a coverage change is needed. California seniors should review coverage during annual Medicare Open Enrollment, after major health or prescription changes, after moving, after provider changes, and whenever plan notices show cost, benefit, network, or drug-list changes.
When California seniors should review Medicare coverage
| Review area | What to confirm | Why it matters |
|---|---|---|
| Annual Open Enrollment | Review coverage before October 15 through December 7 each year. | Plans can change costs, benefits, networks, and drug coverage. |
| Medicare Advantage Open Enrollment | Review January 1 through March 31 if already in Medicare Advantage. | This can be a second look for some Medicare Advantage members. |
| Health changes | Review after a new diagnosis, hospital stay, surgery, therapy need, or specialist referral. | Care needs may change which network, drug coverage, or cost structure fits. |
| Medication changes | Review after new prescriptions, dose changes, expensive medications, or pharmacy changes. | Formularies, tiers, preferred pharmacies, and prior authorization can affect cost. |
| Life changes | Review after moving, losing coverage, entering or leaving a facility, or getting Medicaid or Extra Help. | Some events may create special enrollment rights or change plan fit. |
How to do a practical annual Medicare review
- Gather the Annual Notice of Change, Evidence of Coverage, Medicare card, plan card, medication list, pharmacy list, and doctor list.
- Check whether important doctors, hospitals, specialists, pharmacies, and medications still fit the plan.
- Compare estimated yearly costs, not just the monthly premium.
- Review dental, vision, hearing, transportation, over-the-counter, and other extra benefits only after core care needs are checked.
- Use Medicare.gov Plan Finder and confirm details with the plan or qualified licensed help before changing coverage.
Why waiting can hurt
Families often wait until a denied medication, changed doctor network, high copay, or hospital follow-up problem appears. A scheduled review can catch those risks earlier and give the senior more time to ask careful questions.

Should seniors review Medicare every year?
Yes. A yearly review is wise because plans and personal care needs can change. Reviewing does not mean a senior must switch plans.
What documents help with a Medicare review?
Helpful documents include the Medicare card, current plan card, Annual Notice of Change, medication list, pharmacy list, doctor list, upcoming appointments, and recent bills.

No. The lowest premium may not be the lowest total cost if doctors, prescriptions, pharmacies, copays, referrals, or out-of-pocket exposure do not fit the senior's needs.
Can a caregiver help review coverage?
Yes. A caregiver can help organize information, ask questions, and compare details, while the senior and official or qualified resources confirm decisions.
