Question:

Scope of Regional Lymph Node Surgery/EOD-Lymph Node fields: How do you code these fields if a pt has multiple lymph nodes surgeries at different times? See discussion.

Discussion:

Example: 1/01/03 Biopsy of 1 sentinel lymph node: positive for metastasis. 1/10/03 Modified radical mastectomy and axillary lymph node dissection: ductal carcinoma with 8 neg lymph nodes.

Answer:

For cases diagnosed 1/1/2003 and later: Code Scope of Reg LN Surgery to 7. Code EOD Lymph Nodes field to 6. Code EOD Pathologic Number of Reg LN Positive and Examined fields to 01 and 09 respectively.

For the Scope of Reg LN Surgery use the highest applicable code number if more than one Scope of Reg LN Surgery was performed. The EOD lymph node fields are cumulative and count all lymph nodes removed during the diagnostic and first course treatment procedures.

History:

For cases diagnosed 1998-2002: Code Scope of Reg LN Surgery 98-02 to 3. Code Number of Reg LN Examined (Surgery field) to 08. Code EOD Lymph Nodes field to 6. Code EOD Pathologic Number of Reg LN Positive and Examined fields to 01 and 09 respectively.

SPCM, 3rd Ed, page 128, gives instructions for coding Num of Reg LN Ex in the surgery group. That field is NOT cumulative. Code only the number of lymph nodes examined from the most definitive lymph node surgery. Page 128 does not pertain to the Lymph Nodes and Number of Reg LN Ex fields for EOD, which are cumulative.
