Oth types of non-Hodgkin lymphoma, intrapelvic lymph nodes

This code signifies a diagnosis of a non-Hodgkin lymphoma that doesn't fit into more specific categories, and its primary manifestation is located within the lymph nodes of the intrapelvic region. This includes lymphomas with unusual histologies or those that are not otherwise classifiable but are definitively non-Hodgkin type.

Use this code when the pathology report confirms a non-Hodgkin lymphoma, and the specific type is not precisely defined but is clearly stated as "other specified" or similar terminology. The documentation must explicitly identify the intrapelvic lymph nodes as the primary site of involvement. This code is appropriate when the physician's diagnosis aligns with this level of specificity.

• Ensure documentation clearly specifies "non-Hodgkin lymphoma" and "intrapelvic lymph nodes."
• Do not use this code if a more specific type of non-Hodgkin lymphoma (e.g., follicular, diffuse large B-cell) is identified.
• Confirm the primary site is indeed intrapelvic; avoid confusion with retroperitoneal or inguinal lymph node involvement.
