Code Description

ICD-10 F44.89 is a billable code used to indicate a diagnosis of other dissociative and conversion disorders.

Key Diagnostic Point:

F44.89 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 be triggered by stress or trauma. Unlike anxiety disorders, PTSD, or OCD, which have more defined symptomatology and treatment protocols, dissociative disorders often present with a complex interplay of psychological and physical symptoms. The diagnosis requires careful clinical evaluation to rule out other medical conditions and to understand the patient's psychological history. Treatment typically involves psychotherapy, cognitive behavioral therapy, and sometimes medication to manage associated symptoms. The complexity of these disorders lies in their varied presentations and the need for a comprehensive approach to treatment, which can complicate accurate coding and documentation.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Varied symptom presentation that can overlap with other mental health disorders.
  • Need for comprehensive patient history to differentiate from other conditions.
  • Potential for co-morbid conditions that complicate diagnosis.
  • Variability in treatment approaches and response to therapy.

Audit Risk Factors

  • Inadequate documentation of symptoms and their impact on daily functioning.
  • Failure to document the patient's history of trauma or stressors.
  • Misclassification of symptoms that may overlap with anxiety disorders.
  • Lack of clarity in treatment plans and response to therapy.
