Frequently Asked Questions
Are these doctors in Simi Valley accepting new Medicare patients?
We can't say for sure — CMS's enrollment data confirms a provider is enrolled in Medicare, not whether their practice is currently open to new patients. Call first to confirm they're accepting new Medicare patients before you book.
What does "accepts Medicare assignment" mean?
It means the provider takes Medicare's approved amount as full payment for a covered service, so you only owe your normal deductible and 20% coinsurance — no extra charges. A provider marked "may accept assignment" can go either way, so ask when you call.
Will these doctors work with my Medicare Advantage plan?
Not necessarily. This directory is built from Medicare enrollment data, which applies to Original Medicare. If you have a Medicare Advantage plan, your plan's own network determines who's covered — check your plan's directory first, then confirm with the office directly.
Does Original Medicare cover dental care from these providers?
Original Medicare does not cover routine dental care like cleanings, fillings, or dentures. Some Medicare Advantage plans include dental benefits. See our guide on what Medicare does and doesn't cover for dental.
