Other insomnia not due to a substance or known physiological condition
ICD-10 F51.09 is a billable code used to indicate a diagnosis of other insomnia not due to a substance or known physiological condition.
F51.09 refers to insomnia that is not attributable to any substance use or identifiable physiological condition. This type of insomnia can arise from various psychological factors, including stress, anxiety, depression, or behavioral syndromes. Patients may experience difficulty falling asleep, staying asleep, or waking up too early, leading to significant distress and impairment in daily functioning. Unlike primary insomnia, which is often idiopathic, F51.09 encompasses cases where insomnia is secondary to psychological issues but does not meet the criteria for other specific sleep disorders. It is crucial for healthcare providers to conduct thorough assessments to rule out other sleep disorders, substance use, or medical conditions that could explain the insomnia. Treatment may involve cognitive-behavioral therapy, lifestyle modifications, and, in some cases, pharmacotherapy, depending on the underlying psychological factors.
