What This Code Means
G47.14 is the ICD-10-CM diagnosis code for hypersomnia due to medical condition. Excessive sleepiness that is caused by or results from another medical condition, such as obesity, thyroid disease, or neurological disorders. G47.14 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).
G47.14 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.
Always code the underlying medical condition as an additional diagnosis.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G47.14 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
