The Medicare Care Choices Model aims to expand access to concurrent palliative and curative care for Medicare beneficiaries with serious illnesses. It will test allowing participating hospices to provide supplemental palliative care services to eligible beneficiaries, while receiving curative treatment, in return for a $400 per beneficiary per month fee. Hospices must be Medicare-certified and able to coordinate care. Eligible beneficiaries have advanced cancers, lung disease, heart failure or HIV/AIDS. The model seeks to improve pain and symptom management through 24/7 access to hospice professionals and care coordination over three years. CMS implementation contractors will provide technical support to participating hospices.
