Is F80.9 an HCC code?
No. F80.9 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
F80.9 is the ICD-10-CM diagnosis code for developmental disorder of speech and language, unspecified. This code describes a developmental disorder affecting a child's ability to speak and understand language, but the specific type of speech or language problem is not identified. It is used when a speech or language delay or disorder is present but the exact nature of the condition cannot be determined. F80.9 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).
F80.9 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 only when the specific type of speech/language disorder (such as expressive language disorder F80.1 or phonological disorder F80.0) cannot be determined from the documentation.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F80.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the specific type of speech/language disorder (such as expressive language disorder F80.1 or phonological disorder F80.0) cannot be determined from the documentation
- •Ensure the condition is documented as a developmental disorder; if the speech/language problem is acquired due to injury, stroke, or other medical condition, use a different code category
