At no point will CCA sell, trade, or lease any information collected on our site. The information provided will be used to contact you, provide you with information, or help you enroll. CommonHealth members may pay a premium to MassHealth. The premium amount is determined by the member’s family income. Members must continue to pay this premium after they enroll in One Care. The payment is made directly to MassHealth. If members have questions regarding their premium or would like to set up a payment plan or apply for a hardship waiver, they should contact MassHealth at 800-841-2900 (TTY 800-497-4648).
Medicare beneficiaries may also enroll in One Care through the CMS Medicare Online Enrollment Center, located at https://www.medicare.gov/.
