Inactive residual effect or condition produced after the acute phase of an illness or injury has ended. There is no time limit on when late effects can appear. For example, an individual could suffer an injury and then years later develop arthritis at that site. When listing the diagnostic code, sequence the condition code first and then the late effect code, unless the late effect code is combined with the manifestation in one code or the late effect is followed by the manifestation. Also known as sequelae .
