Code Description

ICD-10 F44.8 is a billable code used to indicate a diagnosis of other dissociative and conversion disorders.

Key Diagnostic Point:

F44.8 encompasses a range of dissociative and conversion disorders that do not fit neatly into other specified categories. These disorders are characterized by a disruption in the normal integration of consciousness, memory, identity, or perception of the environment. Patients may experience symptoms such as altered sense of self, memory loss, or episodes of dissociation that can manifest as physical symptoms without a clear medical cause. Common presentations include non-epileptic seizures, paralysis, or sensory loss that cannot be explained by neurological or medical conditions. The onset of these disorders is often linked to psychological stressors, trauma, or anxiety, and they may co-occur with anxiety disorders, PTSD, or OCD. Treatment typically involves psychotherapy, cognitive behavioral therapy, and anxiety management techniques to help patients cope with their symptoms and underlying issues. Understanding the nuances of these disorders is crucial for accurate diagnosis and coding, as they can significantly impact a patient's quality of life and require tailored therapeutic approaches.

  • Inadequate documentation of symptoms and their impact on daily functioning
  • Failure to document the relationship between psychological stressors and symptoms
  • Lack of clear treatment plans or follow-up notes
  • Misclassification of symptoms that may overlap with other diagnoses

Specialty Focus

Psychiatry

Documentation Requirements

Thorough documentation of patient history, symptomatology, and treatment response is essential. Detailed notes on the patient's psychological state and any trauma history should be included.

Common Clinical Scenarios

Patients presenting with unexplained neurological symptoms, such as paralysis or seizures, following a traumatic event or significant stress.

Billing Considerations

Psychiatrists should be aware of the potential for co-morbid anxiety disorders and PTSD, which may require integrated treatment approaches.

Neurology

Documentation Requirements

Neurologists must document the exclusion of neurological causes for symptoms, including detailed neurological examinations and diagnostic tests.

Common Clinical Scenarios

Patients with non-epileptic seizures or sensory loss that do not correlate with neurological findings.

Billing Considerations

Collaboration with mental health professionals may be necessary to address the psychological aspects of the patient's condition.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of dissociative disorders, improving the ability to capture the complexity of these conditions. F44.8 provides a broader category for cases that do not fit into more specific codes, allowing for better tracking and treatment planning.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of dissociative disorders, improving the ability to capture the complexity of these conditions. F44.8 provides a broader category for cases that do not fit into more specific codes, allowing for better tracking and treatment planning.
