Insomnia is a common sleep disorder characterized by difficulty in falling asleep or staying asleep, or experiencing non-restorative sleep. In the International Classification of Diseases, Tenth Revision (ICD-10), insomnia is classified under the code F51.0.
Here is a coding guide for coders to accurately code insomnia in ICD-10:
ICD-10 Code: F51.0
Description: Insomnia not due to a substance or known physiological condition
Additional Coding Guidelines:
- If the insomnia is due to a substance use disorder or withdrawal, it should be coded as a substance-induced sleep disorder (F51.1).
- If the insomnia is due to a medical condition, such as chronic pain or respiratory distress, it should be coded as a sleep disorder due to a known physiological condition (G47.0).
- If the insomnia is a symptom of a mental disorder, such as depression or anxiety, it should be coded as the underlying mental disorder (e.g., F32.1 for major depressive disorder with insomnia).
- If the insomnia is due to a combination of factors, such as a medical condition and a mental disorder, both codes should be assigned.
It is important to note that coding guidelines may vary depending on the healthcare setting and the specific coding system used. Therefore, it is recommended to consult the official coding guidelines and the healthcare facility’s coding policies to ensure accurate coding.
