Our notes document a 1/99 SEER e-mail stating that tonsillectomy/tonsillectomy with wide excision would be code to 31. Is this still correct? Some of our coders felt that code 27 or 30 would be more appropriate.

Is the removal of the contralateral tonsil incidental removal or do we code it under Surgery of Other Regional Site, Distant Site, or Distant Lymph Nodes? If it is coded, would 5 be the correct code?

For example, chemotherapy and immunotherapy administered first, followed by surgery, then immunotherapy and hormone therapy after surgery. Or is code 4 used for two administrations of chemotherapy before surgery and two more courses after surgery?

2020 Diagnosis: Patient had a right hemicolectomy showing adenocarcinoma of cecum, tumor extends into proximal portion of attached vermiform appendix. Tumor invades through muscularis propria into pericolorectal tissues (NOS). Regional lymph nodes: 06/39. Primary Tumor EOD: Where does the appendix involvement come into coding or will this be based on the pericolorectal tissue (NOS) invasion? What is my Summary Stage? I know it is at least 3 due to regional ln involvement, but the appendix involvement is making me question 3 vs 4.

Can you provide clarification on Rectum primary surgical code 40 Pull through WITH sphincter preservation (colo-anal anastomosis)? Would this be code 30 or 40 due to the colorectal anastomosis? 

It is unclear if code 300 is appropriate, since technically the fissure is comprised of pleura, involvement of the fissure appears to imply a tumor that is no longer localized.

An argument could be made for code 400, since the term traverses could be interpreted as crossing into adjacent lobe, however the lower lobe is not mentioned in this scan.

In Appendix C- Breast (SEER Manual 2015) it states under the codes for TOTAL MASTECTOMY (Codes 40-49, 75): For single primaries only, code removal of involved contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item # 1294). [SEER Note: Example of single primary with removal of involved contralateral breast--Inflammatory carcinoma involving both breasts. Bilateral simple mastectomies. Code Surgery of Primary Site 41 and code Surgical Procedure of Other Site 1.] HOWEVER, underneath that it states code 76 is used for: 76 Bilateral mastectomy for a single tumor involving both breasts, as for bilateral inflammatory carcinoma. So

Since acellular dermal matrix/AlloDerm comes from human tissue donors with cells removed and sterilized to promote regenesis and decrease rejection, is Alloderm coded as "Tissue' as it also "provides an additional layer of tissue between the skin and the implant?

Under the Grade section in the Heme DB for anaplastic large cell lymphoma, NOS it indicates the following:

"Grade - Code grade specified by pathologist. If no grade specified, code 9."

There is no reference in the Grade section that we should look at the Abstractor Notes or a specific Module in the Heme DB for additional information. However, in the Abstractor Notes section it states, "Grade is T-cell (5) unless pathologist specifically designates as a B-cell (see G2 rule)." These two statements are conflicting. Which is the correct grade?

Patient was diagnosed with lambda myeloma based on the M spike found on serum protein electrophoresis. A bone marrow biopsy was performed, but it was an insufficient sample.

SPEP is not listed in the Hematopoietic Database as a lab test that can be used as a definitive diagnostic method. Since the physician did base the diagnosis on the SPEP result, would it be appropriate to assign code 5 (Positive laboratory test/marker study) since there was no histological confirmation?

Under code 5, the Hematopoietic Manual states: Laboratory tests are listed under Definitive Diagnostic Methods in the Hematopoietic Database.
