What This Code Means
Z87.79 is the ICD-10-CM diagnosis code for personal history of other (corrected) congenital malformations. Z87.79 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).
Header codes like Z87.79 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 Z87.79 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
