Additional Info
- Prolymphocytic leukemia is a sub-type of our more general dx code Chronic lymphocytic leukemia (CLL). And as usual, always use the most specific code available -- thus you'd use this code instead of the more general code.
- There are 2 subtypes of Prolymphocytic leukemia:
- B-cell prolymphocytic leukemia
- T-cell prolymphocytic leukemia -- again, there is a more general code for T-cell leukemia, but you should use the most specific one available.
Leukemia vs Lymphoma
Any lymphoma may have a leukemic phase where the abnormal clonal cells appear in the circulation. Though this is sometimes referred to as a "leukemia", even by some oncologists, that is technically incorrect and ICD10 considers them to be lymphomas. This applies to essentially ALL so-called B-cell leukemias, which are actually lymphomas. It also applies to "NK-cell leukemia" which is also a lymphoma
As such, the following so-called "leukemias" should be coded as follows:
- So-called B-cell leukemias describes several different types of lymphoid lymphomas which affect B cells -- and all these should be coded as Lymphoma, NOS
- "B cell chronic lymphocytic leukemia"
- "Precursor B cell lymphoblastic leukemia"
- "Acute Lymphoblastic leukemia, mature B cell type"
- "B cell prolymphocytic leukemia"
- So-called "NK-cell leukemia" -- code as T-cell lymphoma
- Aggressive NK-cell leukemia (also called aggressive NK-cell lymphoma, or ANKL), is a very rare type of NHL. The body makes large numbers of NK cells that are larger than normal. It is grouped with T-cell lymphomas.
- There is a very rare slow-growing (indolent) type of NK-cell leukemia that has a more favorable prognosis. It is called chronic NK-cell leukemia and is treated like T-cell large granular lymphocytic leukemia.
- The most common type of lymphoid leukemia is B-cell chronic lymphocytic leukemia.
