CMS ANOC/EOC REQUIREMENTS
As detailed in section 60.7 of the Medicare Marketing Guidelines manual, all Plans/Part D Sponsors must send the ANOC/EOC (also referred to sometimes as “ANOC Mailings” or ANOC EOC Mailings, or ANOC and EOC Mailings) to Plan Members for receipt by September 30 of each year. New Enrollees with an effective date of October 1, November 1, or December 1, should receive both an EOC for the current contract year and an ANOC/EOC for the upcoming contract year. New enrollees with an effective date of January 1 or later must receive an EOC for the contract year of coverage. Additional materials may not be included in the ANOC/EOC mailing unless otherwise specified. Standalone EOCs do not need to be resubmitted in HPMS.
There are some exception as to the specific timing and the mailing sequence of components for the DSNP, COST, and Employer/Union Group Plans ANOC and EOC Mailings; but, the mandates from CMS regarding ANOC/EOC mailings are strictly enforced, and failure to comply can result in fines and enrollment sanctions for Plans. To ensure that Plans/Part D Sponsors are mailing their ANOC/EOC timely, Plans/Part D Sponsors must indicate the actual mail date in HPMS within three (3) days of mailing.
