ICD-10-CM Code C84.4
Peripheral T-cell lymphoma, not classified
Non-Billable Code
Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail.ICD Code C84.4 is a non-billable code. To code a diagnosis of this type, you must use one of the ten child codes of C84.4 that describes the diagnosis 'peripheral t-cell lymphoma, not classified' in more detail.

The ICD code C844 is used to code Peripheral T-cell lymphoma not otherwise specified
Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), is a subtype of peripheral T-cell lymphoma. Peripheral T-cell lymphoma (PTCL) is defined as a diverse group of aggressive lymphomas that develop from mature-stage white blood cells called T-cells and natural killer cells (NK cells) (see figure for an overview of PTCL subtypes). PTCL is a type of non-Hodgkin’s lymphoma (NHL). NHL affects two particular types of white blood cells: B-cells and T-cells. PTCL specifically affects T-cells, and results when T-cells develop and grow abnormally.
