About D03

D03 is the ICD-10-CM diagnosis code for melanoma in situ. It belongs to block D00-D09 (in situ neoplasms) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D03.0 (of lip), D03.1 (of eyelid, including canthus), D03.2 (of ear and external auricular canal), D03.3 (of other and unspecified parts of face), D03.4 (of scalp and neck), D03.5 (of trunk), D03.6 (of upper limb, including shoulder), D03.7 (of lower limb, including hip) and 2 more.

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