The patient was diagnosed with a carcinoid tumor of the small intestine. The pre-surgical work-up also identified a lung nodule that showed no octreotide uptake, but was indeterminate on biopsy. The imaging differential diagnosis included carcinoid, hamartoma, or a non-calcified granuloma. The patient underwent a resection of the primary small bowel tumor, and the physician noted the lung nodule was of unclear diagnosis. The physician stated a solitary lung metastasis would be atypical, but that lung metastatic involvement could not be ruled out. The physician recommended resection of the lung nodule to ensure that the patient was disease free. The lung wedge resection proved a pulmonary hamartoma.

The rules for coding Surgical Procedure of Other Site are not entirely clear. The definitions for First Course of Therapy in the SEER Manual do state that treatment includes, "Procedures that destroy or modify primary (primary site) or secondary (metastatic) cancer tissue." This would seem to exclude the lung resection as it did not destroy, modify or remove metastatic cancer tissue. However, the instructions for coding Surgical Procedure of Other Site do not address removal of distant sites that are not incidental. The lung resection was not incidental; the physician recommended it to ensure the lung was not involved, but it also disproved metastatic involvement. Should the Surgical Procedure of Other Site field be coded 0 (none) or 4 (non-primary surgical procedure to distant site) in this case?

Operative report indicates a wire localized lumpectomy was performed. The pathology report includes a final diagnosis for two specimens as follows:

A) LEFT BREAST, EXCISION: INFILTRATING DUCTAL CARCINOMA

B) LEFT BREAST, NEW DEEP MARGIN, EXCISION: BENIGN BREAST TISSUES AND BENIGN FIBROFATTY SOFT TISSUES; NO EVIDENCE OF NEOPLASIA.

The definition for Breast surgery code 23 is "Reexcision of the biopsy site for gross or microscopic residual disease". There is no indication whether the re-excision has to be a separate procedure or can be during the same procedure as the excisional biopsy (lumpectomy). Some hospital registrars in our region believe code 22 is more appropriate.

A patient was diagnosed with hepatocellular cancer (HCC) in 2010, and underwent a hepatectomy, and then received a donor liver. In 2014, HCC was discovered in the liver once again. This likely is a new primary, but there are no specific rules to cover this. There are many odd situations involving transplanted organs, many of which pose reportability and multiple primary problems.

Procedure stated = Bilateral skin-sparing mastectomies, left axillary sentinel lymph node biopsy. On the pathology report it indicates two additional lymph nodes were removed that were not SLN. The axillary aspect measures 2 x 2 x 1 cm. Two lymph nodes are identified ranging from 0.5 up to 1 cm. The lymph nodes are bisected and entirely submitted. Final Diagnosis Left breast, mastectomy including nipple: no residual carcinoma; FINAL DIAGNOSIS for LN = Lymph nodes, left axillary sentinel #1; excision: Two lymph nodes examined - negative for tumor (0/2); Two lymph nodes - negative for tumor (0/2)

Should it be coded to where the testis was physically at the time of diagnosis (C621), or should it be coded to C620 to reflect the increased risk for developing malignancy in an undescended testis?
