ICD10 code of Non-Verbal Learning Disorder and ICD9 code

Non-Verbal Learning Disorder (NVLD) does not currently have a specific, dedicated diagnostic code in the ICD-10 or ICD-9 classification systems, as it is not officially recognized as a distinct diagnostic category in the DSM-5. Clinicians typically use broader diagnostic codes, such as "Specific Learning Disorder" or "Social (Pragmatic) Communication Disorder," to facilitate insurance billing and access to services for those living with Non-Verbal Learning Disorder.

Why is there no specific ICD code for Non-Verbal Learning Disorder?

The lack of a unique ICD-10 or ICD-9 code for Non-Verbal Learning Disorder stems from ongoing debates in the psychiatric and neurological communities regarding its classification. Because the clinical profile of Non-Verbal Learning Disorder overlaps significantly with Autism Spectrum Disorder and other neurodevelopmental conditions, it is often categorized under "Other specified neurodevelopmental disorder" (ICD-10 code F88) or similar umbrella terms to ensure patients receive necessary support.

How is Non-Verbal Learning Disorder diagnosed?

Diagnosis of Non-Verbal Learning Disorder is primarily clinical, relying on a comprehensive neuropsychological evaluation rather than a single medical test. Professionals look for a characteristic discrepancy between strong verbal abilities and significant deficits in visual-spatial, motor, and social-pragmatic functioning. Currently, 23 members of the DiseaseMaps community have shared their experiences with Non-Verbal Learning Disorder, highlighting the challenges of obtaining a formal diagnosis in the absence of a standardized medical code.

What are the core challenges of Non-Verbal Learning Disorder?

While the diagnostic coding remains complex, the functional impact of Non-Verbal Learning Disorder is well-documented. Common manifestations include:

• Significant difficulty interpreting non-verbal cues, such as body language and facial expressions.


• Poor visual-spatial organization, often impacting handwriting and mathematical problem-solving.


• Challenges with fine and gross motor coordination.


• Difficulty adjusting to transitions or novel, unstructured social situations.


• Strong rote memory and verbal expression, which can sometimes mask the severity of the underlying spatial deficits.

Next steps

• Consult with a neuropsychologist or developmental pediatrician to obtain a formal assessment for Non-Verbal Learning Disorder.


• Work with an educational advocate to ensure your IEP or 504 plan reflects your specific needs rather than relying on a generic diagnosis.
