In accordance with Disability Evaluation System (DES) Manual: Integrated Disability Evaluation System (IDES), DoDM 1332.18-V2, August 5, 2014, it states...
APPENDIX 10 TO ENCLOSURE 4
IPEB AND FPEB PROCEDURES
1.
GENERAL. The IPEB and FPEB determine a Service member’s fitness in accordance with Appendix 2 to Enclosure 3 of Reference (b), but do not assign disability ratings to conditions. The IPEB and FPEB support the IDES quality control review process in accordance with Enclosure 3 of Reference (b).
2.
IPEB PROCEDURES. The IPEB members must:
a. Within 15 days of receiving the complete and correct MEB case file from the PEB administrator, adjudicate the Service member’s case and forward the findings and recommendations to the PEB administration staff.
b. Within 15 days of receiving proposed disability ratings from the D-RAS, apply the ratings using the diagnostic code(s) provided by the D-RAS to the Service member’s unfitting conditions and publish the disposition recommendation. For example, if the PEB identifies a condition to the D-RAS as schizophreniform disorder, but the D-RAS rates the condition as psychotic disorder not otherwise specified (VASRD 9210), then the PEB will apply the rating as “schizophreniform disorder rated as psychotic disorder not otherwise specified (VASRD 9210).”
c. Evaluate the Service member’s request for FPEB. If a Service member requests an FPEB when the decision of the IPEB is fit for all conditions, then the PEB President or FPEB (or as specified by Military Department regulations) may, but is not required to, grant the Service member’s request. If the request is granted, the PEB administrator prepares the case for an FPEB.
3.
FPEB PROCEDURES. The FPEB members must:
a. Consider Service member rebuttals of issues pertaining to the fitness of conditions for service and the ratings assigned to unfitting conditions.
b. Render a recommendation within 30 days from the date the Service member elects to rebut the IPEB decision. The decision will be formally prepared by the PEB for the Service member.
c. Coordinate recommendations to change the status of conditions between fit and unfit with the D-RAS to ensure VA’s proposed rating accurately reflects the PEB’s final recommendation of unfitting conditions.

As established above, the FPEB is suppose to assigned a DoD rating equivalent to that provided by the DoVA D-RAS for your PTSD medical condition while in the DoD IDES process. Are there other factors not mentioned here? Exactly, what was the FPEB's rationale for awarding a DoD 0% rating? What are the comments from your assigned FPEB attorney also?
That all said and without additional details, it will be difficult to provide any type of sound insightful feedback in reference to your specific inquiry. Take care!
Thus, I quite often comment that "possessing well-informed knowledge is truly a powerful equalizer!"
Best Wishes!
