42 CFR § 418.308 - Limitation on the amount of hospice payments.
(c) The hospice must file its aggregate cap determination notice with its Medicare contractor no later than 5 months after the end of the cap year and remit any overpayment due at that time. Hospices shall file the aggregate cap using data no earlier than 3 months after the end of the cap period. The Medicare contractor will notify the hospice of the final determination of program reimbursement in accordance with procedures similar to those described in § 405.1803 of this chapter. If a provider fails to file its self-determined cap determination with its Medicare contractor within 5 months after the cap year, payments to the hospice will be suspended in whole or in part, until a self-determined cap determination is filed with the Medicare contractor, in accordance with§ 405.371(e) of this chapter.
