- DI 52165.025 Old Interactive Computations Facility (ICF) Function 9 (WC Lump Sum Proration) and Function 28 (WC/PDB)
~~ICF functions #31, #32, and #34 replaced ICF #9 and #28. In some cases, ICF #9 and #28 may be used to perform WC/PDB calculations. Use both programs with caution. There are limitations that will compute incorrect calculations. Before using #9 and #28, review the limitations on the Interactive Computations Facility (ICF) Resource Page for WC/PDB Offset Computations~~**. http://kcnet.kc.ssa.gov/mamwc/OldICF.htm#9_ProgLim**- ICF functions #31, #32, and #34 replaced ICF #9 and #28.

- A. ICF #9 (Workers’ Comp Lump Sum Proration)
~~ICF #9 calculates a lump sum proration with or without expenses. If there are expenses, #9 will calculate the proration using method A, B, and C. For ICF #28 program limitations,~~**see http://kcnet.kc.ssa.gov/mamwc/OldICF.htm**- ICF #9 calculates a lump sum proration with or without expenses.

- If you are not experienced using this program, refer to DI 52170.001 - Manual Computations for Workers’ Compensation/Public Disability Benefit (WC/PDB) Offset to manually calculate the offset.
~~ICF #28 is less user-friendly than the newer offset computation functions. ICF #28 may be used to calculate the average current earnings (ACE) and the amount of offset and a triennial redetermination. However, ICF #28 will not correctly compute a rate change after a redetermination.
