A condition where a person experiences physical symptoms (like weakness, numbness, or difficulty moving) that cannot be explained by a medical disease, caused by psychological stress or trauma. The symptoms are real to the patient but originate from emotional distress rather than physical illness.
Buddy Insight
Conversion disorder with mixed symptom presentation indicates a complex somatoform condition where multiple neurological symptom types (motor, sensory, seizure-like) coexist without organic cause.

Is F44.7 an HCC code?
F44.7 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 F44.7
For F44.7 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 F44.7 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
F44.7 is the ICD-10-CM diagnosis code for conversion disorder with mixed symptom presentation. A condition where a person experiences physical symptoms (like weakness, numbness, or difficulty moving) that cannot be explained by a medical disease, caused by psychological stress or trauma. The symptoms are real to the patient but originate from emotional distress rather than physical illness. F44.7 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).
F44.7 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 F44.7 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 F44.7 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure documentation clearly indicates multiple conversion symptoms affecting different body systems or functions to justify the 'mixed symptom presentation' specificity
- •Verify that medical workup has ruled out organic neurological or medical causes before coding this diagnosis, and document the psychological stressor or trauma when available
Clinical Significance
Conversion disorder with mixed symptom presentation indicates a complex somatoform condition where multiple neurological symptom types (motor, sensory, seizure-like) coexist without organic cause. This diagnosis reflects significant psychological burden and often requires intensive multidisciplinary management. For risk adjustment, it maps to RxHCC 133 and signals high medication utilization for symptomatic management.
Documentation Requirements
- ✓Documentation of at least two different types of conversion symptoms (e.g., motor weakness AND sensory loss AND/or pseudoseizures)
- ✓Negative neurological workup results ruling out organic etiology for each symptom type
- ✓Identified psychological stressor or traumatic event temporally associated with symptom onset
- ✓Functional impairment assessment describing impact on daily activities
- ✓Provider explicitly stating 'conversion disorder' or 'functional neurological symptom disorder' with mixed presentation
Commonly Confused Codes
- •F44.4 (Conversion disorder with motor symptom or deficit): use when ONLY motor symptoms are present, not mixed
- •F44.5 (Conversion disorder with seizures or convulsions): use when ONLY pseudoseizures are present
- •F44.6 (Conversion disorder with sensory symptom or deficit): use when ONLY sensory symptoms are present
- •F45.0 (Somatization disorder): involves multiple somatic complaints across organ systems, not neurological conversion symptoms
- •G44.89 (Other headache syndrome): organic headache, not psychogenic
