Buddy Insight
Dissociative stupor is characterized by a profound reduction or absence of voluntary movement and normal responsiveness to external stimuli, in the absence of a physical or other psychiatric disorder that could explain it.

Is F44.2 an HCC code?
F44.2 is not in the CMS-HCC V28 or V24 community payment model, but it does map to Personality Disorders, Anxiety, and Other Specified Mental Disorders under the Part D RxHCC model.

HCC Category Mapping
Each model's RAF is its CMS base weight for that model's standard population, so weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for F44.2
For F44.2 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed F44.2 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
F44.2 is the ICD-10-CM diagnosis code for dissociative stupor. A state of reduced consciousness or responsiveness without a medical explanation, where the person appears awake but is unaware of surroundings and unable to respond normally. F44.2 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders (f40-f48).
F44.2 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This code does not map to a CMS-HCC V28 payment category. Capture depends on documentation that supports the diagnosis; verify the HCC assignment against the current CMS mapping for the applicable payment year. Coders reviewing F44.2 should check whether additional documentation would support a more specific child code in the same hierarchy that does map to a payment HCC, capturing the correct specificity is the highest-impact RAF improvement available within accurate coding.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F44.2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure medical causes of altered consciousness have been ruled out before coding
- •Document the level of responsiveness and duration of the stuporous state
Clinical Significance
Dissociative stupor is characterized by a profound reduction or absence of voluntary movement and normal responsiveness to external stimuli, in the absence of a physical or other psychiatric disorder that could explain it. The patient appears unresponsive but clinical examination reveals no organic basis. This is a rare condition that often presents in emergency settings.
Documentation Requirements
- ✓Profound reduction or absence of voluntary movement and responsiveness
- ✓Clinical examination findings excluding organic catatonia, neurological conditions, or metabolic causes
- ✓EEG or neuroimaging as appropriate to exclude organic causes
- ✓No evidence of a physical disorder (stroke, encephalitis, metabolic encephalopathy) explaining the stupor
- ✓Evidence of recent psychological stress or trauma as a precipitant
- ✓Mental status changes inconsistent with the degree of apparent unresponsiveness
- ✓Documentation distinguishing from catatonia associated with schizophrenia or mood disorders
Excludes 2, Not included here, may code separately
Commonly Confused Codes
- •R40.1 (Stupor): R40.1 is for stupor without specification of dissociative origin; F44.2 is specifically dissociative
- •F20.2 (Catatonic schizophrenia): Catatonic schizophrenia involves catatonia in the context of a psychotic disorder; dissociative stupor lacks psychotic features
- •F06.1 (Catatonic disorder due to known physiological condition): Organic catatonia caused by medical conditions; F44.2 is functional/psychological
- •G93.1 (Anoxic brain damage, not elsewhere classified): Organic causes of unresponsiveness must be ruled out before coding dissociative stupor
