About D10

D10 is the ICD-10-CM diagnosis code for benign neoplasm of mouth and pharynx. 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: D10.0 (lip), D10.1 (tongue), D10.2 (mouth), D10.3 (mouth), D10.4 (tonsil), D10.5 (oropharynx), D10.6 (nasopharynx), D10.7 (hypopharynx) and 1 more.

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