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

Other codes that can never be billed with G47.3

These codes carry an Excludes1 note pointing at G47.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G47.3 alone.

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

Risk adjustment

G47.3 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 G47.3

9 child codes. Green means billable.
