Dear Slorcoe,
You will not really find any hard and fast guidance on rating this as TDRL v. PDRL. In all but one recent case, it was necessary to go to the FPEB hearing before it was accepted that all means of treatment had been exhausted, no improvement was likely, etc.
One case came back PDRL right from the outset, but that was puzzling as the NARSUM narrative was quite vague and not as well written as others. While I would like to say that it was our rebuttal that put us over the top, I think that it was simply the mindset of the medical officer on the IPEB.
My advice- ensure that the NARSUM shows that you have reached the maximum benefit of medical treatment, no improvement is likely and all other means of treatment have been exhausted.
