If your insurer does not provide a breakdown (how much of PIP is for Medical Benefits), You have to make a goo-faith estimate. Reasonable options are to 1) claim 1/3 of the PIP premium as Medical Benefits, or 2) claim the majority (80%?) of the PIP premium as Medical Benefits. My rationale for the 80% approach is that, of the three coverages included in PIP, medical costs are almost certainly the most costly.
