Other insomnia

This code represents a diagnosis of insomnia that does not fit into more specific categories of sleep-related breathing disorders, hypersomnia, or circadian rhythm sleep-wake disorders. It encompasses various forms of difficulty initiating or maintaining sleep, or non-restorative sleep, that are not otherwise classified.

Use this code when documentation specifies insomnia without further detail regarding its etiology or type, or when it's explicitly stated as "other insomnia." This code is appropriate for primary insomnia or when the specific cause of insomnia is unknown or not clearly documented as another specific type.

• Ensure documentation clearly states "insomnia" and lacks further specificity for more precise coding.
• Avoid using this code if a more specific type of insomnia (e.g., due to a mental disorder, substance-induced) is documented; always code to the highest level of specificity.
• Consider sequencing this code as a primary diagnosis if the insomnia is the main reason for the encounter, or as a secondary diagnosis if it's a comorbidity.
