ICD-10 Code F88 – Other disorders of psychological development (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F88 – Other disorders of psychological development
What it is
F88 covers developmental problems in psychological functioning that do not fit a more specific diagnosis. Use it for documented developmental impairment when the record does not support a narrower code.
Clinical signs
Clinical features vary; refer to documentation. You may see delays or atypical development in areas such as learning, language, coordination, or social functioning, but the chart should support the diagnosis.
When to use this code
Use F88 when the provider documents an unspecified or other developmental disorder affecting psychological development and no specific category applies. It is appropriate when the record describes developmental delay or impairment but does not identify a more exact condition. Check documentation if the diagnosis is vague.
Do not use for
Do not use this code when a more specific developmental disorder is documented, such as a language, learning, or motor disorder. Avoid it for normal developmental variation or when the note does not clearly support a disorder.
Coding tip
Query the provider for the most specific developmental diagnosis before assigning F88.
