Affording Nursing Home in Tennessee for the wife of a deceased veteran?

Could anyone provide insight into how others afford nursing home services? My mother needs to move from assisted living to a nursing home, but we were quoted $9,000 a month. Her social security, retirement, and VA surviving spouse benefits do not cover the amount.

One nursing home mentioned a QIT (Qualified Income Trust), but they also stated they don’t work with Medicaid, so I’m not sure what good a QIT would do or how it would work with other facilities, if those facilities even accept Medicaid.

VA facilities were mentioned as well, but it doesn’t look like the VA will cover surviving spouse nursing home services at 100%. Thank you for your help.
