N.M. Admin. Code § 8.248.600.12
The applicant/recipient is responsible to report changes affecting eligibility within 10 days of when the change took place. A re-determination of eligibility is made every 12 months. If a LIS recipient/applicant becomes eligible for certain medicaid categories; SSI, QMB, SLIMB, QI-1, WDI, IC, and HCBW, they will still be eligible for LIS. CMS will notify the beneficiary that they are now deemed eligible, because of categorical relatedness and will take over the re-determination of eligibility on a yearly basis. A change notice will be sent to the LIS recipient. For the year 2006, all certification periods will end December 31, 2006. Effective January 1, 2007, the certification period will be 12 months from the month of application or recertification.
