How many years must all records related to health history be retained after the last entry?

The correct duration for retaining records related to health history after the last entry is 40 years. This policy is in place to ensure that comprehensive medical information is available for veterans and individuals who have served in the military, as health issues can arise many years after service. The 40-year retention period reflects the understanding that certain health conditions, particularly those that may have delayed onset or are related to military service, may not be diagnosed until long after the period of active duty.

Maintaining these records for an extended period supports various needs, including continuity of care, legal protection, and historical reference for medical research or claims processing. The retention guidelines are established by the Department of Defense and other regulatory bodies to ensure that former service members have access to necessary medical information when they need it most.
