About D19

D19 is the ICD-10-CM diagnosis code for benign neoplasm of mesothelial tissue. It belongs to block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D19.0 (of pleura), D19.1 (of peritoneum), D19.7 (of other sites) and D19.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
