About D13

D13 is the ICD-10-CM diagnosis code for benign neoplasm of other and ill-defined parts of digestive system. 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 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D13.0 (esophagus), D13.1 (stomach), D13.2 (duodenum), D13.3 (intestine), D13.4 (liver), D13.5 (ducts), D13.6 (pancreas), D13.7 (pancreas) and 1 more.

Don't report D13 together with the conditions in its Excludes1 note: benign stromal tumors of digestive system (D21.4).

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