When you sign this form, it means that you understand the following:

* One Care Plans have a contract with the federal government and with Massachusetts.
* The health services I get with my new plan may be different than the services I had before.
* I must keep Medicare Part A, Part B and MassHealth.
* I can be in only one Medicare Plan at a time.
* By joining a One Care Plan I will end my enrollment in another Medicare health or presciption drug plan.
* I must tell Medicare and MassHealth about any prescription drug coverage that I have or may get in the future.
* If I move, I need to tell MassHealth.
* As a member of a One Care Plan, I have the right to appeal if I don’t agree with my One Care Plan’s decisions about payment or services.
* The One Care Plans do not usually cover people while they’re out of the country.

* On the date my One Care Plan coverage begins, I will have access to my current doctors for 90 days.

Beyond 90 days, I must get my health care from my One Care Plan's providers and pharmacies, except for emergency or urgently needed care, out of area dialysis, or if I get my One Care Plan's approval to see other providers in some circumstances.

My One Care Plan will help me find new providers if I need them.

* I understand that if a sales agent employed by the One Care Plan helps me enroll, the One Care Plan may pay that person.
* By joining a One Care Plan, I know that the One Care Plan may share my information with Medicare and MassHealth and other plans as necessary for treatment, payment, and health care operations.
* I understand that prescription drugs are covered, but not always the same ones I’m already taking. I understand that I’ll have access to my current drugs for at least 30 days, until I can switch to a different drug.
* I know that my One Care Plan may share my information, including my prescription drug information, with Medicare and MassHealth.

They may release it for research and other purposes, as allowed by federal or state statutes and regulations.

* The information on this form is correct to the best of my knowledge. I understand that if I intentionally provide false information on this form, I’ll be disenrolled from my One Care Plan.
