Amnestic disorder due to known physiological condition
Chapter 5:Mental, Behavioral and Neurodevelopmental disorders
ICD-10 F04 is a billable code used to indicate a diagnosis of amnestic disorder due to known physiological condition.
Amnestic disorder due to known physiological condition is characterized by significant memory impairment that is directly attributable to a physiological condition, such as a neurological disorder, substance abuse, or a medical illness. Patients may experience difficulties in forming new memories (anterograde amnesia) or recalling past memories (retrograde amnesia). This disorder is often associated with organic mental disorders, where the underlying cause is identifiable and can include conditions like traumatic brain injury, stroke, or chronic alcohol use. Unlike other forms of amnesia, which may be psychological in nature, F04 is specifically linked to physiological factors. The clinical presentation may vary, but it often includes confusion, disorientation, and personality changes, which can complicate the patient's overall mental state. Diagnosis typically involves a thorough medical history, neurological examination, and cognitive assessments to rule out other potential causes of memory impairment. Treatment focuses on addressing the underlying physiological condition and may include rehabilitation strategies to improve cognitive function.
Detailed neurological assessments and imaging results.
Patients presenting with memory loss following a stroke or traumatic brain injury.
Ensure that the physiological cause is clearly documented to support the diagnosis.
Comprehensive mental status examinations and history of substance use.
Patients with memory impairment due to substance-induced conditions.
Differentiate between organic and functional causes of memory impairment.
Used to assess cognitive function in patients with suspected amnestic disorders.
Detailed report of cognitive assessments and findings.
Neurologists and psychologists should collaborate on documentation.
F04 is primarily caused by identifiable physiological conditions such as neurological disorders, substance abuse, or medical illnesses that directly impact memory function.
F04 is differentiated by the clear link to a physiological condition, whereas other amnestic disorders may not have such a direct cause.
