Code 46: Attached to other organ (on imaging or surgical observation); pathology says no invasion of the other organ. Code 57: Attached to other organ; pathology is positive for invasion of other organ, or pathology does not specify whether there is invasion of the other organ.

Example 1: Code extension to 46 [Adherent to other organs or sturcture, but no microscopic tumor found in adhesion(s)]. The tumor was attached to the duodenum, but not invading

Example 2: Code extension to 46 [Adherent to other organs or structure, but no microscopic tumor found in adhesion(s)]. The tumor was attached to peritoneum & retroperitoneum, but not invading based on negative margins and no peritoneum or retroperitoneum specimen submitted to pathologist.

"Suspicious" is listed as a term indicating involvement. There is no exception noted for cytology reports. See page 122 of the 2007 SEER manual.

Assign CS extension code 80 [Systemic disease] for extramedullary plasmacytoma involving more than one site. Use code 80 when extramedullary plasmacytoma is NOT single, solitary, unifocal, isolated, mono-ostotic or localized. Code 80 can also be used when the bone marrow is involved but the plasma cells are <10%.

Do not apply EOD instructions to CS.

For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.

Extension code 40 is for extension from the tonsil to the back (lower) part of the soft palate, or soft palate, NOS. Code 42 is for extension to the front (higher, nasopharyngeal surface) part of the soft palate.

Inferior soft palate is the back (lower) part of the soft palate (C051). Superior soft palate is the front, (nasopharyngeal surface) of the soft palate (C113).

Assign CS extension code 40 to the case above.

Assign code 60 for a primary in the head of the pancreas extending to the superior mesenteric artery. CS Extension code 54 should be Superior mesenteric VEIN and code 60 should be Superior mesenteric ARTERY. An errata will be issued by CS. In addition, extension 54 indicates resectable disease and code 60 is not resectable.

Both the 2007 SEER manual (page C-1072) and the CS Version 01.04.00 manual (page II-550) have been updated to include 9734 [extramedullary plasmacytoma] under extension code 10.

Code what is known. In the example above, the tumor size and the extension are known and can be coded. The information is limited, but not completely missing.

Code what you DO know rather than coding nothing. Any metastases from the kidney would have been discovered during the workup of the rectal cancer.

Yes, assign code 10 [Tumor confined to one lung] for a mass in one lobe when none of the descriptions in codes 11 to 80 are documented.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign CS Extension code 40 [Atelectasis/obstructive pneumonitis that extends to the hilar region but does not involve the entire lung (or atelectasis/obstructive pneumonitis, NOS)].

CS extension code 10 does not apply when any condition described in codes 20-80 exists.
