Non-Billable/Non-Specific Code

G47.1 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
The 2023 edition of ICD-10-CM G47.1 became effective on October 1, 2022.
This is the American ICD-10-CM version of G47.1 - other international versions of ICD-10 G47.1 may differ.

Type 2 Excludes

Type 2 Excludes Help

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (G47.1) and the excluded code together.

Subtypes include primary hypersomnia disorders (e.g., idiopathic hypersomnolence; narcolepsy; and kleine-levin syndrome) and secondary hypersomnia disorders where excessive somnolence can be attributed to a known cause (e.g., drug affect, mental disorders, and sleep apnea syndrome). (from j neurol sci 1998 jan 8;153(2):192-202; thorpy, principles and practice of sleep medicine, 2nd ed, p320)
