G47.3: Sleep apnea

Non-billable headerICD-10-CM

G47.3 is a non-billable header ICD-10-CM code for sleep apnea. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • apnea NOS (R06.81)
  • Cheyne-Stokes breathing (R06.3)
  • pickwickian syndrome (E66.2)
  • sleep apnea of newborn (P28.3-)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

  • any associated underlying condition

Excludes2 inherited from the categories above G47.3

Not part of this code, but both may be coded when both are present.

Written on G47: Sleep disorders

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

Other codes that can never be billed with G47.3

Their own Excludes1 notes name this code, so the conflict is not listed above.

  • Z03.83Encounter for observation for suspected conditions related to home physiologic monitoring device ruled out
  • R06.81Apnea, not elsewhere classified

Risk adjustment

No CMS-HCC V28 category: this code does not change a RAF score.
