ICD-10 Code F71 – Moderate intellectual disabilities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F71 – Moderate intellectual disabilities
What it is
F71 identifies moderate intellectual disability, a developmental condition marked by significant limits in intellectual functioning and adaptive skills. You should use it when the record clearly documents this level of severity.
Clinical signs
Common findings include delayed language and learning, need for support with daily living, and limited independent problem-solving. Clinical features vary; refer to documentation.
When to use this code
Use F71 when the provider documents moderate intellectual disability, moderate mental retardation, or an equivalent statement. It may also apply when the note describes moderate impairment in intellectual and adaptive functioning with no more specific subtype recorded.
Do not use for
Do not use this code for mild, severe, or profound intellectual disability. If the record only says developmental delay, learning difficulty, or another condition without confirmed intellectual disability, check documentation.
Coding tip
Code the documented severity exactly as stated and avoid inferring F71 from general cognitive impairment.
