Surgery of Primary Site--Head & Neck: Is a composite resection performed for an oral cavity primary coded to 40 [Radical excision of tumor, NOS], 41 [Radical excision of tumor only], 42 [Combination of 41 with resection in continuity with mandibles (marginal, segmental, hemi-, or total resection], 43 [Combination of 41 with resection in continuity with maxilla (partial, subtotal, or total resection)]? See discussion.
Example:
Patient underwent composite resection of left soft palate, tonsillar fossa, medial pterygoid and lateral tongue for a primary of the retromolar trigone. There was no mention of an excision of the mandible; however, the procedure included the application of a mandibular reconstruction plate.
Use surgery codes 40-43 for composite resection of an oral cavity primary. In the case example, code Site-Specific surgery as 42 [Combination of 41 WITH resection in continuity with mandible]. Even though excision of mandible was not mentioned, there was mention of a mandibular reconstruction plate. Since the retromolar trigone is ON the mandible, resection of the mandible is likely.
EOD-Clinical Extension--Prostate: How is this field coded when biopsies of the prostatic apex are positive and the physician clinically stages the case as T1c?
For cases diagnosed 1998-2003:
Code clinical extension to 33 [arising in the prostatic apex] when a biopsy of the prostatic apex is positive for malignancy, with no further evidence of involvement. If biopsies of both the apex and another site within the prostate (for example right lobe) are positive and there is no mention that the malignancy arose in the apex, code extension to 34 [extending into the prostatic apex].
Scope of Regional Lymph Node Surgery 2003+/Number of Regional Lymph Nodes Examined--Hematopoietic/Brain/Lymph Nodes/Ill-defined/Unknown: Are codes 9 [Unknown; not stated] and 99 [Unknown; not stated] used respectively for these data items for the mentioned primary sites?
For cases diagnosed Jan 2003 and later:
The Number of Regional Lymph Nodes Examined field is blank for 2003+ cases.
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
Date of Diagnosis/Diagnostic Confirmation: How are these fields coded when a physician statement of diagnosis predates a positive biopsy? See Description.
A mass seen on EGD with negative biopsy 12/28/01. Needle core biopsies 1/14/02 were diagnostic of GIST. Gleevec treatment was initiated 2/02, and in discharge summary 5/27/02, the physician says the GIST was diagnosed on EGD.
Code the date of diagnosis as 01/2002. Code the diagnostic confirmation as positive histology. EGD revealed a "mass." Biopsies of the "mass" seen on EGD were negative before January 2002.
Surgery of Primary Site--Head & Neck: How is this field coded for a surgery titled "Parotidectomy with facial nerve dissection"? See Description.
If the operative report is not titled "total parotidectomy," can we assume that less than total parotidectomy was done? Can we assume that "facial nerve dissection" and "facial nerve monitoring" are other ways of stating "facial nerve spared"?
Use the best information available to determine whether or not all of the parotid has been removed. It is important to read the entire operative report and review the content of the pathology report. The Op report will usually include wording about how much was removed, and this can be confirmed by the path report. Do not make assumptions about the extent of the surgery based solely on the title used on the operative report.
For cases diagnosed 1998-2003: Code 30 [less than total parotidectomy] can be used when the parotid is not totally removed, but the exact type of partial parotidectomy cannot be determined. "Facial nerve monitoring" and "Facial nerve dissection" are synonymous with "facial nerve sparing."
EOD-Extension--Lung: For a left upper lobe lung tumor that extends across the fissure into the left lower lobe, should this field be coded to 10 [Tumor confined to one lung] or 77 [Separate tumor nodules in different lobe]?
For cases diagnosed 1998-2003: Assign EOD extension code 10 [Tumor confined to one lung]. EOD extension code 10 applies to a single tumor within one lung, even one that crosses over a fissure into another lobe. EOD extension code 10 is not correct if the tumor extends to the pleura, or if there is atelectasis, obstructive pneumonitis or malignant pleural effusion. Code 77 is incorrect because that is a separate tumor nodule in a different lobe.
Histology (Pre-2007)/Primary Site/Diagnostic Confirmation: How would these fields be coded for a diagnosis of cholangiocarcinoma based on clinical findings only? See Discussion.
We have a case of reported "cholangiocarcinoma" of the liver diagnosed only by a CT of the abdomen. There is no pathologic confirmation. CT ABD: Heterogeneous liver mass suspicious for cholangiocarcinoma; mass causes right portal & right hepatic vein occlusion & right and left biliary duct dilatation....
Should this be coded to cholangiocarcinoma by radiology alone and should it be liver as primary site?
For tumors diagnosed prior to 2007:
Code according to the prevailing medical opinion in this case. If no further information can be obtained, code as cholangiocarcinoma of the intrahepatic bile duct.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Reportability--Appendix: Is an appendiceal carcinoid with one periappendiceal lymph node positive for metastatic carcinoid tumor reportable to SEER? See Discussion.
The patient had an appendectomy followed by a hemicolectomy. No residual carcinoid tumor was identified but there was one lymph node positive for metastatic carcinoid tumor.
Yes, this carcinoid is reportable to SEER. This carcinoid is malignant by virture of the lymph node metastasis. Code the behavior as /3.
EOD-Lymph Nodes--Colon: Are deposits of carcinoma in the pericolic fat still coded as lymph nodes when the pathology report states, "there is a high likelihood that these represent foci of venous invasion"? See Description.
Patient underwent resection for adenocarcinoma of the rectum. Path final diagnosis stated: "Regional lymph nodes: met carcinoma in 18 of
43 lymph nodes. Pathologic stage (AJCC/UICC 6th edition): pT3, V2, pN2, pMx. See comment." Path comment: "There are additional macroscopic stellate deposits of carcinoma in the pericolic soft tissue. According to the 6th edition of the AJCC staging manual, these should be designated as "V2," indicating that there is a high likelihood that these represent foci of venous invasion."
For cases diagnosed 1998-2003: Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node.
When the number of deposits is not mentioned, code Number of Regional Nodes Positive as 97 [Positive nodes but number of positive nodes not specified]. Unless the procedure is documented as a dissection, code Number of Regional Nodes Examined as 98 [Regional lymph nodes surgically removed but number of lymph nodes unknown/not stated and not documented as samping or dissection; nodes examined, but number unknown].
