Frequently Asked Questions

Are these doctors in Clearlake 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.

Do doctors in Clearlake accept Medicare assignment?

82% of the 130 Medicare-enrolled clinicians listed in Clearlake accept assignment — meaning they take Medicare's approved amount as full payment, so you only owe your deductible and 20% coinsurance. Another 18% are marked "may accept assignment," 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.

Do any doctors in Clearlake offer telehealth visits?

17% of the Medicare-enrolled clinicians listed in Clearlake offer telehealth, per CMS enrollment data. Look for the "Telehealth available" badge below, and confirm with the office which visit types they offer remotely.
