neoplasm of the lip.

Coding professionals should review the entries under the main
terms lymphoma and leukemia in the ICD-10-CM Index to Diseases and Injuries and compare them to the entries found under the same terms in ICD-9-CM.
The four common types of leukemia are chronic lymphocytic
leukemia, chronic myeloid leukemia, acute lymphocytic (
lymphoblastic) leukemia, and acute myeloid leukemia. 1 There are
other types of leukemia as well.
It is helpful to know the difference between lymphoid stem
cells and myeloid stem cells. According to the National Cancer Institute, “A myeloid stem cell matures into a myeloid blast.
The blast can form a red blood cell, platelets, or one of several
types of white blood cells. A lymphoid stem cell matures into a
lymphoid blast. The blast can form one of several types of white
blood cells, such as B cells or T cells.” 2 Myeloid leukemia affects
myeloid cells, and lymphocytic leukemia affects lymphoid cells.
Lymphoma consists of Hodgkin and non-Hodgkin lymphoma. Hodgkin lymphoma is a rare form of cancer. Non-Hodgkin
lymphoma is divided into many different types, including B-cell
non-Hodgkin lymphomas (such as Burkitt lymphoma), chronic
lymphocytic leukemia/small lymphocytic lymphoma, diffuse
large B-cell lymphoma, follicular lymphoma, immunoblastic
large cell lymphoma, mantle cell lymphoma, and precursor
B-lymphoblastic lymphoma. Other types include T-cell non-Hodgkin lymphomas (such as anaplastic large cell lymphoma),
mycosis fungoides, and precursor T-lymphoblastic lymphoma.
Polycythemia Vera
The entries under the main term polycythemia in the ICD-10-
CM Index to Diseases and Injuries are different than the en-
tries in the ICD-9-CM Index to Diseases. In ICD-9-CM, vera is
a nonessential modifier to polycythemia. That is not the case in
ICD-10-CM, where polycythemia vera is coded differently than
polycythemia.
