Oth non-follic lymphoma, nodes of ing region and lower limb

This code signifies a diagnosis of a non-follicular lymphoma that is not otherwise specified, specifically affecting the lymph nodes located in the inguinal region and/or the lower extremities. This type of lymphoma originates from lymphocytes and is characterized by its growth pattern not being follicular.

Use this code when documentation specifies a non-follicular lymphoma, such as diffuse large B-cell lymphoma or peripheral T-cell lymphoma, with primary or metastatic involvement of the lymph nodes in the groin or leg. The physician's notes should clearly indicate the specific anatomical location of the affected lymph nodes.

• Ensure the documentation explicitly states "non-follicular" or provides a specific type of lymphoma that is known to be non-follicular.
• Verify that the affected lymph nodes are precisely identified as inguinal or lower limb; avoid using for generalized lymphadenopathy.
• Distinguish from follicular lymphoma (C82.-) and other specified types of non-Hodgkin lymphoma with different anatomical sites.
