Oth types of non-hodg lymph, nodes of ing rgn and lower limb

This code signifies a diagnosis of a non-Hodgkin lymphoma that doesn't fit into more specific classifications, and is located in the lymph nodes of the inguinal region or lower limb. It indicates a primary or secondary involvement of these specific anatomical sites by an atypical non-Hodgkin lymphoma.

Apply this code when documentation clearly states a diagnosis of "other specified non-Hodgkin lymphoma" with confirmed involvement of lymph nodes in the groin or leg. This typically follows a biopsy and pathological review confirming the lymphoma type and its precise anatomical location.

• Ensure the documentation specifies "other specified" non-Hodgkin lymphoma, not an unspecified or another defined type.
• Verify the anatomical site is explicitly stated as inguinal lymph nodes or lymph nodes of the lower limb.
• Do not use for Hodgkin lymphoma or for non-Hodgkin lymphoma affecting other body regions.
