G47.0 – Insomnia | ICD-10-CM

G47.0 diagnosis code: Insomnia

Understanding the ICD-10 code G47.0 was essential for healthcare professionals dealing with patients experiencing insomnia. Insomnia is a common sleep disorder, and this code played a crucial role in accurate documentation and billing.

Insomnia ICD code G47.0 was the ICD-10 code specifically used for diagnosing and coding insomnia. G47.0 represented the diagnosis of insomnia, a condition characterized by difficulty falling asleep, staying asleep, or experiencing non-restorative sleep.

Insomnia can manifest in various forms, including acute or chronic insomnia, each with distinct characteristics and diagnostic criteria. The code G47.0 allowed for differentiation based on severity and duration.

Some of the more appropriate specific codes to use are the following:

  • G47.00 - Insomnia, unspecified: This is meant to be used if the patient is confirmed to have insomnia, but it isn't known/currently specified as to what specific insomnia they have.
  • G47.01 - Insomnia due to medical condition: This is meant to be used if the patient is confirmed to have insomnia due to a medical condition.
  • G47.09 - Other insomnia: This is meant to be used if the patient is confirmed to have insomnia, but the type of insomnia they have doesn't fit either of the two previous ICD codes mentioned (e.g., persistent organic factor insomnia disorder).
  • Z72.820 - Sleep deprivation: This is meant to be used if the patient is confirmed to have sleep deprivation.
  • Z72.821 - Inadequate sleep hygiene: This is meant to be used if the patient is confirmed to have inadequate sleep hygiene, which might be contributing to their insomnia.

Is G47.0 billable?

The G47.0 ICD-10-CM code is no longer billable. The other specific codes mentioned earlier are valid and billable, so please use any of those instead and when appropriate.
