Borderline intellectual functioning

This code signifies cognitive abilities that are below average but do not meet the diagnostic criteria for intellectual disability. Individuals with borderline intellectual functioning typically have an IQ range of 71-84, experiencing mild difficulties in learning and adaptive behaviors.

Assign this code when documentation indicates cognitive limitations that fall between average intelligence and intellectual disability. This is often supported by psychological testing results, such as an IQ score within the 71-84 range, and clinical observations of mild academic or adaptive challenges.

• Do not code concurrently with intellectual disabilities (F70-F79) due to the Excludes1 note.
• Ensure documentation clearly distinguishes this condition from a specific learning disorder (F81.-).
• Consider if an associated neurodevelopmental disorder (e.g., ADHD) is also present and should be coded.
