ICD-10-CM F04: Amnestic Disorder Coding Guide
ICD-10-CM code F04 specifies an amnestic disorder caused by a known physiological condition. Accurate documentation requires identifying the underlying cause and recording specific memory impairments. This diagnosis may involve behavioral health considerations when memory deficits impact mental health. Clinicians must detail the patient's medical history, cognitive assessment results, and any related medical conditions, ensuring comprehensive documentation for reimbursement and compliance.
Overview
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.
Coding Complexity
Rating: Medium
Factors:
- Requires thorough understanding of physiological conditions causing amnesia.
- Differentiation from other types of amnestic disorders.
- Need for comprehensive documentation of the underlying condition.
- Potential overlap with other mental health diagnoses.
- Variability in clinical presentation among patients.
Comparison:
Compared to related codes such as F00 (Dementia in Alzheimer's disease) and F01 (Vascular dementia), F04 is less complex due to its specific linkage to identifiable physiological conditions. However, it requires careful documentation to establish the connection between the amnestic disorder and the underlying medical condition, which can complicate coding.
Audit Risk Factors:
- Inadequate documentation of the physiological condition.
- Failure to specify the type of amnesia (anterograde vs. retrograde).
- Misclassification of the disorder as a primary psychiatric condition.
- Lack of evidence supporting the diagnosis in the medical record.
- Inconsistent coding across different encounters.
Specialty Focus
- Specialty: Neurology
Documentation Requirements: Detailed neurological assessments and imaging results.
Common Clinical Scenarios: Patients presenting with memory loss following a stroke or traumatic brain injury.
Special Considerations: Ensure that the physiological cause is clearly documented to support the diagnosis. - Specialty: Psychiatry
Documentation Requirements: Comprehensive mental status examinations and history of substance use.
Common Clinical Scenarios: Patients with memory impairment due to substance-induced conditions.
Special Considerations: Differentiate between organic and functional causes of memory impairment.
Coding Guidelines
According to ICD-10 coding guidelines, F04 should be used when there is clear evidence of a physiological condition causing the amnestic disorder. Documentation must specify the nature of the physiological condition and its direct impact on memory function. Exclusion criteria include cases where memory impairment is primarily psychological or due to external factors not related to a physiological condition.

Billing Information
Billing for F04 requires comprehensive documentation of the patient's medical history, the physiological condition leading to the amnestic disorder, and any assessments performed. Clear linkage between the diagnosis and treatment provided is essential for reimbursement.

Q: What are the documentation requirements for ICD-10-CM F04?
When documenting ICD-10-CM code F04, it is crucial to provide detailed information about the specific memory impairments and their linkage to a known physiological condition. Clinicians should document the patient’s cognitive function assessment, including standardized test results, and any relevant neurological or medical evaluations identifying the cause of the amnestic disorder. Additionally, describing the functional impact of memory impairments on the patient’s daily life and noting any comorbid conditions is essential for comprehensive coding and substantiating medical necessity.
Q: How does ICD-10-CM code F04 apply to behavioral health?
ICD-10-CM code F04 is relevant to behavioral health due to the potential impact of amnestic disorders on a patient’s mental wellness. Memory impairments can lead to significant psychological distress, affecting mood, anxiety levels, and overall mental health. When documenting this code, behavioral health clinicians should note any changes in the patient's mental health status, including symptoms of depression or anxiety, that may be secondary to cognitive deficits, as well as any therapeutic interventions aimed at supporting mental health.
Q: What are the complexities in coding with ICD-10-CM F04?
Coding with ICD-10-CM F04 involves complexities such as correctly identifying the underlying physiological condition causing the amnestic disorder and distinguishing it from other cognitive disorders. Clinicians must ensure that the documentation clearly establishes the causal relationship between the physiological condition and memory impairment. Accurate coding is critical for appropriate reimbursement and requires thorough patient history and assessment to avoid audit issues. Complex cases may involve interdisciplinary evaluation and documentation by neurology, psychiatry, and primary care specialties.
Q: What are some audit considerations for ICD-10-CM F04?
Audit considerations for ICD-10-CM F04 include ensuring that the documentation supports the diagnosis with clear evidence of a physiological condition causing the amnestic disorder. Records should include comprehensive assessments and confirmatory tests that align with clinical guidelines. Coders and auditors must verify that the documentation is complete, consistent, and justifies the clinical decision-making process. Auditors may also check for any overlap with other cognitive or memory-related diagnoses to prevent coding inaccuracies.
Q: What specialty-specific documentation is relevant for ICD-10-CM F04?
Specialty-specific documentation for ICD-10-CM F04 will vary based on the etiology of the amnestic disorder. Neurologists should document detailed neurological findings, while psychiatrists might focus on cognitive and behavioral evaluations. Collaboration between specialties is particularly relevant in cases requiring both neurological exams and psychological assessments. Additionally, documenting interventions from rehabilitation specialists can provide context about functional impairments and therapeutic goals, supporting a holistic view essential for interdisciplinary care and effective treatment planning.
