What This Code Means
T74 is the ICD-10-CM diagnosis code for adult and child abuse, neglect and other maltreatment, confirmed. T74 sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering other and unspecified effects of external causes (t66-t78).
Header codes like T74 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 T74 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
