Before the month a COLA becomes effective, the system usually generates a notice to tell the recipient about the event and how much his/her SSI payments will be. If the COLA will result in an increase in SSI payments, the system generates an SSA-L8151. If the COLA will result in a decrease (usually the result of title II COLA coordination), the system generates an SSA-L8155. If the COLA will result in the same amount of money due, the system generates an SSA-L8166.
