G47 — Sleep disorders

Non-billable headerICD-10-CM

G47 is a non-billable header ICD-10-CM code for sleep disorders. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

nightmares (F51.5)
nonorganic sleep disorders (F51.-)
sleep terrors (F51.4)
sleepwalking (F51.3)

Other codes that can never be billed with G47

These codes carry an Excludes1 note pointing at G47. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G47 alone.

R06.81Apnea, not elsewhere classified
F45.8Other somatoform disorders
Z03.83Encounter for observation for suspected conditions related to home physiologic monitoring device ruled out
Z72.820Sleep deprivation
Z72.821Inadequate sleep hygiene

Risk adjustment

G47 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead G47

9 child codes. Green means billable.
