Personality and behavioral disorders due to known physiological condition (F07) ICD-10-CM
The F07 code range covers personality and behavioral disorders due to known physiological condition with 6 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

About the F07 Code Range
F07 codes are used to classify personality and behavioral disorders caused by a known physiological condition affecting the brain. These codes help identify specific changes in personality or behavior resulting from brain injury, neurological illness, or surgical procedures.
The ICD-10 code for personality change due to known physiological condition (F07.0) covers disorders also called Temporal lobectomy behavior syndrome, Frontal lobe syndrome, or Organic personality disorder. It describes personality changes linked directly to brain damage or dysfunction. Codes like F07.81 identify postconcussional syndrome, known as postconcussion state or traumatic encephalopathy, reflecting lasting behavioral effects after brain trauma. Other codes like F07.89 cover additional specific personality and behavioral syndromes such as Limbic epilepsy personality syndrome or explosive character disorder, all tied to identifiable physiological brain conditions. When the disorder is confirmed but not otherwise specified, F07.9 is used. These codes guide coders in accurately documenting behavioral symptoms rooted in physiological brain conditions rather than primary psychiatric disorders.
