IN CALIFORNIA, when you need treatment first, at least a year. Most go 19-20 months. People with multiple surgeries have claims running 9-10 years.
There can be a small 'war' over each procedure requiring reports on each side taking 6 weeks to get each report, then waiting 8 weeks to get the hearing and POW! 3.5 months just disappeared.
I hope for your sake it's 10 times faster in Alabama (but my personal experience is that everything moves a little more slowly in 'Bama).
