0.000What This Code Means
A condition where someone abuses multiple drugs and develops progressive cognitive decline and dementia-like symptoms that are caused by the substance use.
Coding Tips
- •Document cognitive domains affected (memory, executive function, language, etc.)
- •Differentiate from primary dementia by establishing the temporal relationship with substance abuse
Clinical Significance
This code identifies persisting dementia caused by other psychoactive substance exposure, representing irreversible neurotoxic brain damage. Substance-induced persisting dementia indicates permanent cognitive decline requiring long-term supportive care, cognitive rehabilitation, and ongoing supervision. Accurate documentation is essential for risk adjustment as these patients have substantially elevated care needs comparable to other dementia etiologies.
Documentation Requirements
- ✓Provider documentation specifying the psychoactive substance(s) involved (e.g., designer drugs, bath salts, kratom, polysubstance use)
- ✓Clinical documentation supporting substance abuse pattern (maladaptive use pattern causing clinically significant impairment) without meeting criteria for dependence
- ✓Cognitive assessment documenting persistent deficits in memory, executive function, or other cognitive domains
- ✓Provider documentation that the dementia is caused by substance use and persists beyond the period of acute intoxication or withdrawal
- ✓Assessment and plan addressing the substance use disorder with treatment approach documented
Commonly Confused Codes
F19.20-F19.29 (Other psychoactive substance dependence) — dependence indicates a more severe pattern with tolerance, compulsive use, or withdrawal; abuse is a less severe use patternF19.90-F19.99 (Other psychoactive substance use, unspecified) — unspecified use is used when abuse vs. dependence is not documentedF19.16 (Substance-induced persisting amnestic disorder) — amnestic disorder involves primarily memory impairment without the broader cognitive decline of dementiaF01-F03 (Vascular or unspecified dementia) — for primary dementia not caused by substance useF10-F16 (Specific substance codes: alcohol, opioids, cannabis, sedatives, cocaine, stimulants) — use substance-specific codes when the substance is identified; F19 is for 'other' or multiple unspecified substances
