ICF and ICD codes provide a standard language of disability in young children

Area of Science:

• Pediatrics
• Rehabilitation Medicine
• Public Health

Background:

• Early intervention services are crucial for young children's development.
• Accurate classification of eligibility reasons is essential for service provision and research.
• Existing classification systems may require integration for comprehensive documentation.

Purpose of the Study:

• To evaluate a hierarchical algorithm for classifying early intervention eligibility.
• To assess the combined utility of the International Classification of Functioning, Disability and Health (ICF) and International Statistical Classification of Diseases (ICD).
• To analyze reasons for eligibility in a large cohort of young children.

Main Methods:

• Utilized a nationally representative sample of over 5,500 children in early intervention.
• Developed a hierarchical algorithm integrating ICF and ICD codes.
• Classified eligibility reasons into four major categories: Body Functions/Structures, Activities/Participation, Health Conditions, and Environmental Factors.

Main Results:

• An average of 1.5 eligibility reasons were identified per child.
• The majority of children (77%) had codes in the Body Function/Structures category.
• Health Conditions codes were present in 41% of the sample, while Activities/Participation and Environmental Factors were less common (10% and 5%, respectively).

Conclusions:

• The International Classification of Diseases (ICD) and International Classification of Functioning, Disability and Health (ICF) can be jointly utilized.
• This combined approach provides a common language for documenting disability characteristics in early intervention.
• The findings support the use of integrated ICF and ICD coding for improved classification and understanding of child disability.
