Follicular lymphoma grade II, spleen

This code signifies a specific type of non-Hodgkin lymphoma, follicular lymphoma, which is characterized by a grade II cellular differentiation. The disease is specifically located in the spleen, indicating splenic involvement without mention of other sites.

Use this code when documentation clearly specifies follicular lymphoma, explicitly graded as "grade II," and the spleen is identified as the primary or sole site of involvement. This diagnosis is typically confirmed by biopsy and histopathological examination.

• Ensure the pathology report explicitly states "follicular lymphoma grade II" and confirms splenic involvement.
• Do not use this code if the grade is unspecified or if other sites of involvement are documented without specific splenic mention.
• Consider additional codes for any associated symptoms or complications, such as splenomegaly (R16.1).
