F48.8 ICD-10-CM Code: Other specified nonpsychotic mental disorders

F48.8 is the ICD-10-CM diagnosis code for other specified nonpsychotic mental disorders. This code is used for mental health conditions that don't involve losing touch with reality (psychosis) but don't fit neatly into other specific diagnostic categories. It's a catch-all category for various emotional or behavioral disorders that a doctor has specifically documented but that aren't classified elsewhere. F48.8 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders (f40-f48).

F48.8 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.

Always review the provider's documentation carefully to identify the specific condition being treated, as F48.8 should only be used when a more specific F48.x code doesn't apply.
