0.000What This Code Means
A person who is dependent on inhalants and has developed a mood disorder (such as depression or bipolar disorder) directly caused by the inhalant use.
Coding Tips
- •Ensure the mood disorder is documented as inhalant-induced rather than a primary psychiatric condition
- •Consider the temporal relationship between inhalant use and mood disorder onset
Clinical Significance
Inhalant dependence with induced mood disorder captures chronic inhalant users who have developed depression, mania, or emotional dysregulation directly caused by neurotoxic effects of inhalants. Toluene and other solvents damage frontal lobe white matter, producing mood disturbances that may persist even after cessation.
Documentation Requirements
- ✓Documentation of inhalant dependence
- ✓Specific mood symptoms (depressive, manic, irritable, mixed)
- ✓Provider statement linking mood disturbance to inhalant use
- ✓Neuropsychological assessment if available
- ✓Brain imaging findings when available (white matter changes)
- ✓Treatment plan addressing both dependence and mood disorder
