About C76.4

C76.4 is the ICD-10-CM diagnosis code for malignant neoplasm of upper limb. It belongs to category C76 (malignant neoplasm of other and ill-defined sites), block C76-C80 (malignant neoplasms of ill-defined, other secondary and unspecified sites) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within C76 (malignant neoplasm of other and ill-defined sites), C76.4 is specifically for malignant neoplasm of upper limb. Related codes cover head, face and neck (C76.0), thorax (C76.1), abdomen (C76.2), pelvis (C76.3), lower limb (C76.5) and other specified ill-defined sites (C76.8).

To report this condition, pick the subcode that matches the documentation: C76.40 (limb), C76.41 (limb) and C76.42 (limb).

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