HCC Category Mapping

What This Code Means

A condition where a person loses memory of important personal information or events, typically following a traumatic or stressful experience, without a physical cause.

Coding Tips

• •Document the type of amnesia (localized, selective, generalized) if specified in clinical notes
• •Ensure documentation distinguishes this from organic amnesia caused by medical conditions or substance use

Clinical Significance

Dissociative amnesia involves inability to recall important personal information, usually of a traumatic or stressful nature, that is too extensive to be explained by ordinary forgetfulness. This condition maps to HCC 153 under V28 with a significant RAF weight of 1.241, reflecting the complexity and resource utilization associated with dissociative disorders. Under V24 it maps to HCC 60 (Personality Disorders).

Documentation Requirements

• ✓Inability to recall important autobiographical information, usually traumatic or stressful in nature
• ✓Memory loss is inconsistent with ordinary forgetting and is too extensive for normal forgetfulness
• ✓Symptoms cause clinically significant distress or functional impairment
• ✓Disturbance is not attributable to substances (alcohol blackouts, drug effects) or a neurological condition (head injury, seizure disorder)
• ✓Not better explained by dissociative identity disorder, PTSD, somatic symptom disorder, or neurocognitive disorder
• ✓Neurological workup documented to rule out organic causes
• ✓Mental status examination findings including memory testing
