What This Code Means

T84.328 is the ICD-10-CM diagnosis code for displacement of other bone devices, implants and grafts. T84.328 sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering complications of surgical and medical care, not elsewhere classified (t80-t88).

Header codes like T84.328 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for T84.328 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
