V40.1
ICD-9-CMThis code signifies a diagnosis of mental or behavioral issues that manifest primarily as difficulties with communication, encompassing both speech and broader communication abilities. It points to a psychological or behavioral origin for the communication impairment, rather than a purely physical or neurological one.
This code is appropriate for patients presenting with communication disorders where a mental health professional has identified a behavioral or psychological component as the root cause. Examples include selective mutism, psychogenic aphonia, or communication difficulties stemming from severe anxiety or trauma. It should be used when the primary etiology of the communication problem is determined to be psychological or behavioral.
