Leave of absence pay continuation

I’m currently on LOA while I recover from a motorcycle crash. My 6 weeks of pay continuation is up, but I still have another 6 weeks before I can return to work. I’m receiving benefits from the Hartford, but it’s not nearly enough to cover monthly expenses. I read somewhere that you can use 16 hours of PTO per week in addition to the benefits, but now I can’t find it anywhere in HR/SOP. Does anyone know specifically where to look to find that? Thanks!
