Your attorney did you no great service, as medical bills this high are ALWAYS included in suits as long as the person who hit you had coverage.
Facet blocks are not expensive- Medicare cost is about $2200 per block but the anesthesia was probably upward of $3,000 for the anesthesia and doc (billed in units of time- the longer procedure, the higher the cost), OR cost about $2,500 per case. Figure 10K max per anesthesia session.
PT costs no more than $150 per session. Average is $75 for initial $60 for follow-up and the high end figure depending on what procedures they did while there. MAX 3K.
On the high end, the care was about $35K
I don't know where 120K number came from, but you still should have been able to recover a chunk of change.....if the other guy's insurance would have covered it, or he has $$$$.
I hope this helps you-
Feel free to ask me anything you need....
