Other organic sleep disorders

This code signifies sleep disturbances that are directly attributable to an underlying physiological or neurological condition, rather than primary sleep disorders or psychiatric causes. It encompasses a range of sleep-wake cycle disruptions, insomnia, or hypersomnia symptoms that are secondary manifestations of another medical illness.

Use this code when documentation clearly links a patient's sleep disorder to an identifiable organic cause, such as neurological diseases (e.g., Parkinson's, dementia), metabolic disorders, or other systemic medical conditions. It is appropriate for sleep disturbances that resolve or improve with treatment of the underlying organic etiology.

• Always sequence the underlying organic condition as the primary diagnosis, with this code as a secondary diagnosis.
• Avoid using this code for primary sleep disorders (e.g., insomnia, sleep apnea) or sleep disturbances due to mental health conditions.
• Ensure physician documentation explicitly states the causal link between the organic condition and the sleep disturbance.
