Veterans seeking treatment for a service connected disability are not subject to any minimum length of service requirements. Veterans seeking treatment for conditions that are not service connected and who first entered service before September 7, 1980 may be eligible for most medical treatment if they have at least one day of active duty, and their discharge was under honorable conditions.
Enlisted personnel who first entered service after September 7, 1980 and officers who were commissioned after October 16, 1981 must meet the minimum active duty requirement which is commonly known as the “24 month rule” or the “2 year rule.” This requirement states that the veteran must have completed at least 24 months of active duty, OR the full period for which “called” or ordered to active duty.
