ICD-10 Code F44.2 – Dissociative Stupor (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F44.2 – Dissociative stupor
What it is
Dissociative stupor is a condition in which a person has a marked reduction or absence of voluntary movement and responsiveness, without a physical cause explaining the state. You should code the dissociative disorder when documentation identifies this diagnosis.
Clinical signs
Typical documentation may describe immobility, mutism, and reduced response to external stimuli. Clinical features vary; refer to documentation, and confirm that other medical, neurologic, or substance-related causes were not identified.
When to use this code
Use F44.2 when the provider documents dissociative stupor, stupor of psychogenic origin, or a similar dissociative presentation. It may also fit when the record shows profound unresponsiveness attributed to dissociation after evaluation excludes an organic cause. If the note is unclear, check documentation.
Do not use for
Do not use this code for coma, catatonia, syncope, intoxication, or neurologic stupor from a known medical condition. If the diagnosis is another mental disorder or the cause is uncertain, check documentation.
Coding tip
Before assigning F44.2, verify that the provider links the stupor to a dissociative disorder rather than a physical or substance-related cause.
