The PCAFC provides benefits and clinical support to Family Caregivers of veterans who incurred serious injury or had serious injury aggravated in the line of duty of active service. Initially applying to veterans injured before May 7, 1975 or from September 11, 2001 onward, Congress in 2018 expanded PCAFC benefits to caregivers of veterans injured before 9/11 and made changes that led VA to revise its eligibility criteria. VA then implemented a transition phase to re-evaluate the eligibility of legacy applicants, legacy participants, and their caregivers under the revised criteria and to continue to improve and expand the program. Legacy veterans initially had to be a participant in the PCAFC program by September 30, 2020, or an applicant by October 1, 2020. On September 21, the VA published an interim final rule to extend this program for legacy veterans by three years while VA completes the re-evaluation.
