MISSISSIPPI DIVISION OF MEDICAID Eligibility Policy and Procedures Manual CHAPTER 102 – Non-Financial Requirements Page |121 Effective Month: September 2018 SLMB Duals and SLMB-Only – DEI is “S” Recipients with Medicare and full Medicaid who have income above 100% FPL but at/below 120% FPL are referred to as SLMB duals. Recipients in COE-051 are SLMB-only eligible. Refer to 400.05.03 for a discussion SLMB dual eligibility. The Buy-In effective date for Part B is the first month of eligibility for both Medicare & Medicaid. Example: An applicant with Medicare approved for SLMB in August with eligibility retro to May has a Part B Buy-In effective date of May (provided Medicare is present for May). The same is true if the applicant applies for full coverage and is determined to be an SLMB-dual eligible. QI-Only – DEI is “U” Recipients in COE-054 are QI-only. There is no dual eligibility possible for the QI group as specified in 400.05.04A. • The Buy-In effective date for payment of the Part B premium is the first month of eligibility for QI. • Example: A QI applicant approved in August with retro eligibility to July will have a Buy-In effective date of July. Dual eligible – DEI is “D” Recipients with Medicare and full Medicaid with income over 120% FPL are dually eligible for Medicaid and Medicare. • The Buy-In effective date for Part B is the second month after disposition of the application. • Examples: A HCBS applicant with income over 120% FPL approved for HCBS in June has a Buy-In effective date of August. A HCBS recipient approved in June has a future Medicare effective date of September. The “second month after disposition” has been met so the Buy-In effective date is September.
