A staple in assessing and valuing injury and related monetary damages claims, life care plans have traditionally encapsulated damages computations associated with present and anticipated future rehabilitation interventions related to contested events, the most common involving personal injury, medical malpractice, and product liability. The needs and sophistication of the injury claims assessment process have continued to evolve since the inception of life care plans and accordingly affect the services life care planners contribute to resolve disputes over the need for and value of litigated future rehabilitation interventions. After a brief history and overview of life care planning, this article describes how the discipline evolved to its current state. The authors then discuss how lawyers’ discernments in prosecuting cases have led to the need for three variations/derivatives of the traditional life care plan: the life care plan cost comparison, the interpolated life care plan, and the international life care plan. Standards of practice considerations follow. According to the Commission on Rehabilitation Counselor Certification (CRCC), life care planning is a career pathway for certified rehabilitation counselors (CRCs). Rehabilitation counselors encounter a myriad of physical and psychosocial factors that affect the rehabilitation process. CRC certification and training prepares counselors to holistically address complex areas of rehabilitation following a catastrophic illness or injury. According to the CRCC Code of Ethics, CRCs have a responsibility to the public to engage in practices that are based on accepted research methodologies and evidence-based practices. They need to remain current with developments in evidence-based practice. Notably, the three variations/derivatives of the traditional life care plan presented in this article address pertinent standards of practice considerations.
