Is R49.8 an HCC code?
No. R49.8 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
R49.8 is the ICD-10-CM diagnosis code for other voice and resonance disorders. Various problems with voice quality and sound resonance that don't fit into other specific categories, such as hoarseness, nasality, or other voice changes. R49.8 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering symptoms and signs involving speech and voice (r47-r49).
R49.8 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.
Use this code when documentation describes voice disorders that are not dysphonia, dysarthria, or other specifically classified conditions.
