What This Code Means

F06.33 is the ICD-10-CM diagnosis code for mood disorder due to known physiological condition with manic features. Elevated mood, increased energy, or manic-like symptoms that result from a known medical condition affecting the brain or body. F06.33 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering mental disorders due to known physiological conditions (f01-f09).

F06.33 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Ensure the manic features are secondary to the medical condition, not primary bipolar disorder.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for F06.33 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
