Based on the information you provided, your veteran has both a documented TBI and PTSD, is undergoing VA treatment, and fits eligibility. It appears that with the documentation, only the ADL assistance has been considered, which you indicate that night terrors, fugue states, and safety issues are his primary needs – these often fall under the Supervision and Protection requirements for the PCAFC program. Document in straightforward bullet point form the tasks you assist with for the “veteran’s wellbeing” and safety – this seems quite clear-cut, and if review the letter provided to you for the REASONS you were denied. The list you have formed now will be clearer and less likely to be denied as they strongly fit the criteria for Supervision and Protection.
