Is F80.4 an HCC code?
No. F80.4 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
F80.4 is the ICD-10-CM diagnosis code for speech and language development delay due to hearing loss. Delayed speech and language development that is directly caused by hearing loss. Once the hearing loss is addressed, language development typically improves. F80.4 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering pervasive and specific developmental disorders (f80-f89).
F80.4 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 hearing loss separately (H90.x or H91.x codes) as the primary etiology.
