What This Code Means
D19 is the ICD-10-CM diagnosis code for benign neoplasm of mesothelial tissue. D19 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
Header codes like D19 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 D19 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
