Hi Cement,
I've had many, many of these claims. Yes you may owe the TTD--or Not, depending upon the last PTP report. I would reserve the claim for TTD money going future-YOU could put it in a trust account..
What I used to do was send out a delay of TTD, due to the fact that there is no PTP auth continuing TTD. Also, remember when a person is "incarcerated," well, there are many things that happen in jail, etc., of which I'll leave to your imagination...
Does this I/W have an atty??? Can you get the PTP to visit he/she in jail??? Does the PTP know that the applicant is incarcerated??? I would definately send out a "delay" of TTD, pending verification of disability. If there is an AME involved, some will go to the facility and examine them.
I once had a case...Involved an I/W who was sent to prison for lifting kitchen cabinets (after stealing them) and caught on film. Was in prison for 3 years--but come to find out, he/she was on probation for many minor crimes. The back TTD was about 15K. I settled the case for 15K via C&R to lose it.
As it turned out, the prior C/A and D/A knew of the prior incarcerations and kept sending the checks. They were cashed by a
"friend." The I/W was detained in Oregon or Washington, can't remember. However the prior C/A spent $$$$$$$ on 3 knee replacements, while all of this was going on. I managed to get an AME into the detention facility and C&R an otherwise $100k plus

claim down to $15k.
Please do send out the delay of TTD ASAP to CYA. (I hate acronyms) Also got the AME/PTP go to the prison.
Best of luck to you!
