What This Code Means
F88 is the ICD-10-CM diagnosis code for other disorders of psychological development. A developmental disorder affecting psychological or behavioral development that does not fit into other specific developmental disorder categories. F88 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).
F88 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.
Use this code for developmental disorders not classified elsewhere in the F80-F89 range.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for F88 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
