Question:

EOD-Extension--Lymphoma: What code is used to represent this field for a lymphoma that involves the spleen and lymph nodes above the diaphragm (e.g., involvement of only the spleen below the diaphragm and cervical lymph nodes above the diaphragm)?

Discussion:

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 32 [30 + involvement of the spleen; III S]. The spleen is counted twice (once as the spleen and a second time as a lymph node region below the diaphragm). As a result, the EOD-Extension field is coded to reflect involvement of lymph node regions on both sides of the diaphragm plus involvement of the spleen. See Note 1 on the EOD scheme that states "Any lymphatic structure is to be coded the same as a lymph node region."
