Indiana SSP 2017, 2018, 2019

Indiana 2011 SSP Payment Values: https://www.ssa.gov/policy/docs/progdesc/ssi_st_asst/2011/in.html

These values remained in effect for 2017, 2018, and 2019.

This recent SSA POMS page confirms this. It states that "SSI recipients living in these facilities who are entitled to a $30.00 SSI payment will also receive a State-administered supplemental payment of $22.00," which matches the payment values in the 2011 SSA source, indicating that the supplement amount has not changed.

Start by locating the Indiana SSP payment rules and compare their 2017–2019 entries with the linked 2011 SSA page and POMS confirmation. Done means the implementation reflects the $22 state supplement alongside the $30 SSI payment for the stated years, with the relevant project checks passing.
