In simple words: Other intellectual disabilities mean someone has trouble learning, solving problems, and understanding things compared to others their age.They also have difficulty with everyday tasks and social skills. This diagnosis is given when a person's intellectual disability doesn't fit into other, more specific types.

Other intellectual disabilities represent a constellation of impairments characterized by significant limitations in both intellectual functioning (reasoning, learning, problem-solving) and adaptive behavior (conceptual, social, and practical skills).These limitations originate before age 18 and are reflected in significantly subaverage intellectual functioning (IQ score typically below 70), alongside compromised adaptive functioning impacting daily living, social interaction, and independent functioning. This ICD-10 code is applied when the specific type of intellectual disability doesn't fit into other, more specific categories within the F70-F79 range.Diagnosis involves standardized IQ testing, assessment of adaptive functioning, clinical observation, and interviews with relevant individuals.

Example 1: A 5-year-old child presents with significant delays in language development, difficulty with self-care activities (dressing, eating), and challenges in social interaction. Standardized testing reveals an IQ of 65 and significant deficits in adaptive functioning. A diagnosis of F78 is assigned., A 16-year-old adolescent exhibits limited academic progress despite support services, struggles with daily living tasks, and demonstrates impaired social judgment. Psychological evaluation confirms intellectual disability and a diagnosis of F78 is given., A 20-year-old adult is assessed for persistent difficulties in independent living and employment, with challenges in communication and social skills. IQ testing and adaptive behavior assessments confirm an intellectual disability not meeting criteria for specific types, leading to a diagnosis of F78.

Detailed history and physical examination, including developmental history.Results of standardized IQ tests (e.g., Wechsler scales).Assessment of adaptive functioning using standardized tools (e.g., Vineland Adaptive Behavior Scales).Educational and social history.Observations from parents, teachers, and other caregivers.Information on any associated medical or neurological conditions.

** F78 is a residual category, used when the patient's intellectual disability doesn't neatly fit into the more specific intellectual disability codes. The severity and specific needs of each individual with F78 will vary widely.
