This section applies to you if you are a LEOFF Plan 2 member who becomes disabled in the line of duty per RCW 41.26.470.
Example: A LEOFF Plan 2 member has asymptomatic congenital osteoarthritis, a degenerative joint disease. While on duty, the member suffered a knee injury. Absent the osteoarthritis, the knee injury may not have been disabling. However, the preexisting degenerative joint disease prevented full recovery from the injury, leaving the member unable to resume LEOFF duties. In this case, the member could qualify for a LEOFF plan 2 duty disability benefit.
