G47.33Obstructive sleep apnea (adult) (pediatric)

Billable / specific codeICD-10-CM

G47.33 is a billable, specific ICD-10-CM code for obstructive sleep apnea (adult) (pediatric). It is valid for submission on a claim.

Excludes1 — never code together

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

  • obstructive sleep apnea of newborn (P28.3-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Obstructive sleep apnea hypopnea

Risk adjustment

G47.33 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.

Medicare coverage

G47.33 is named in 43 Medicare coverage policies 43 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
