On a monthly basis the Department of Veteran's Affairs transmits a file of all Veterans and Veterans spouses receiving a VA pension and/or compensation benefit payment. The interface calculates the VA chargeable income for SSI purposes and posts this amount to the SSR. VA income discrepancies create diaries for field office development. The purpose of this interface is to eliminate SSI overpayments caused by inaccurate recipient reporting of VA compensation (type C unearned income) or VA pension (type E unearned income) by obtaining the correct amounts from VA and posting the income to the SSR. It also enables SSA to efficiently implement a Medicare outreach program, identify income limits for certain individuals, and determine an individuals potential eligibility for Medicare Savings Programs (MSP) and identify these individuals to the States. OEEAS is responsible for the front-end Pre-Edit program that filters the incoming VA file and generates a report containing erroneous values. OASSIS is responsible for the VA/SSR interface and calculation.
