What This Code Means
G47.33 is the ICD-10-CM diagnosis code for obstructive sleep apnea (adult) (pediatric). A common sleep disorder where the airway becomes partially or completely blocked during sleep, causing breathing interruptions and poor sleep quality in both adults and children. G47.33 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering episodic and paroxysmal disorders (g40-g47).
G47.33 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Specify whether the diagnosis is for adult or pediatric patient, as severity criteria differ.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G47.33 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Specify whether the diagnosis is for adult or pediatric patient, as severity criteria differ
- •Document severity level (mild, moderate, severe) based on apnea-hypopnea index (AHI) when available
Excludes 1, Do NOT code together
- obstructive sleep apnea of newborn (P28.3-)
