Code Description

ICD-10 F42.3 is a billable code used to indicate a diagnosis of hoarding disorder.

Key Diagnostic Point:

Hoarding disorder is characterized by persistent difficulty discarding or parting with possessions, regardless of their actual value. This behavior results in the accumulation of items that congest and clutter active living areas, significantly impairing the individual’s ability to use those spaces. The disorder often coexists with other mental health conditions, such as anxiety disorders, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD). Individuals with hoarding disorder may experience significant distress or impairment in social, occupational, or other important areas of functioning. The condition can lead to unsafe living conditions, social isolation, and increased risk of fire hazards. Treatment typically involves cognitive-behavioral therapy (CBT) focused on reducing the urge to hoard and improving decision-making skills regarding possessions. Medications may also be prescribed to address co-occurring anxiety or mood disorders. Accurate diagnosis and coding are essential for effective treatment and insurance reimbursement.
