Multiplicity Counter/Type of Multiple Tumors--Breast: How are these data items coded for a single breast primary composed of both in situ and invasive disease when measurements are provided for both the invasive and in insitu components? See Discussion.
Breast cancer, invasive duct carcinoma with DCIS, 1.3 cm, DCIS 3.7 cm. "The in situ carcinoma is very extensive in this lumpectomy. It is present contiguously from sides 1A through 1L sparing only the final 8 mm of medial margin. In situ and invasive carcinoma are prominently present along almost the entire superior margin." Is the mult counter 02 with Type of mult tumor 30, or one tumor?
Because there are individual measurements for each of these tumors, code the multiplicity counter 02 [Two tumors present]. Code Type of Multiple Tumor as 30 [In situ and invasive].
Reportability--Brain and CNS: In addition to Schwannoma, are there additional types of benign tumors that arise in peripheral nerves along the spinal cord that are not reportable? See Discussion.
Are neuroepitheliomatous neoplasms such as ganglioneuroma, gangliocytoma, ganglioglioma occurring along the spinal cord reportable? Are nerve sheath tumors such as neuroma occurring along the spinal cord reportable? Angioma?
Reference: SINQ 20051071; Primary Central Nervous System Tumors, NPCR Training Materials 2004
Reportability depends on the location of the tumor. Tumors in the following sites are reportable:
C700 - C709
C710 - C719
C720 - C729
C751 - C753
Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Please note: spinal schwannomas arising in the nerve root or spinal dura are reportable.
Type of Multiple Tumors--Colon: How is this field coded for a case in which the patient is found to have two in situ polyps and an adenocarcinoma arising in a polyp all in the same segment of the colon? See Discussion.
Code 30 would not count the fact that these are polyps. Code 31 states "AND a frank adenocarcinoma." What would be the correct code?
Assign code 30 [In situ and invasive] in this case. Code 31 does not apply here because frank adenocarcinoma is not present.
Ambiguous Terminology/Date of Diagnosis: How would you code the diagnosis date when the body of an imaging report uses reportable ambiguous terminology while the final impression in that same report uses non-reportable ambiguous terminology? Would you code the diagnosis date to the date of the scan or to the subsequent biopsy date that confirmed a malignancy? See Discussion.
Within the body of a mammogram report, the radiologist stated, "diffuse inflammatory tissue throughout the rt breast w/ large rt axillary lymph nodes, consistent with an inflammatory carcinoma of rt breast." His final impression, however, said "extremely suspicious rt breast w/ extremely dense breast parenchyma and adenopathy in axilla, suggesting an inflammatory carcinoma." The patient then went on to have a biopsy, which was indeed positive for cancer.
Accept the reportable ambiguous terminology from the body of the mammogram. Record the date of the mammogram as the date of diagnosis.
The guidelines on page 4 of the 2007 SEER manual addressing discrepancies within the medical record can be applied to discrepancies within one report.
The instructions are:
If one section of the medical record(s) uses a reportable term such as
apparently and another section of the medical record(s) uses a term that is not on the reportable list, accept the reportable term and accession the case.
First Course Treatment--Melanoma: How and where is the excision for an in-transit metastasis coded if the in-transit metastasis is coded in CS Lymph Nodes? See Discussion.
Excision of skin of scalp nodule reveals in transit metastasis of melanoma. Patient also has lung metastasis and begins systemic treatment. No primary tumor identified.
Code the excision in Surgical Procedure of Other Site because no primary tumor was identified.
CS Extension--Ovary: Are "non-invasive implants" identified per pathology coded differently than "invasive implants"?
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.No, non-invasive and invasive implants are not handled differently in collaborative staging for ovary.
MP/H Rules/Multiple Primaries--Breast: How many primaries are abstracted when bilateral breasts contain DCIS? Is a physician statement referring to this situation as one primary ignored? See Discussion.
Patient has microcalcifications both breasts. Has bilateral mastectomy. Path report states Left breast multifocal DCIS predominantly micropapillary. Right breast two foci of DCIS micropapillary.
For cases diagnosed 2007 or later:
There are two primaries in this case.
Using the 2007 MP/H rules for breast, go to the multiple tumors module and start with Rule M4. Stop at rule M7. Tumors on both sides (right and left) are multple primaries.
Always use the 2007 Multiple Primary rules to determine the number of primaries. Do not use the physician statement.
Reportability--Breast: Is a final path diagnosis of "phyllodes tumor, borderline (malignant, low grade)" reportable if the comment states "Features favor the diagnosis of a borderline phyllodes tumor (or also called malignant phyllodes tumor of low grade)"?
No, borderline phyllodes tumors (PT) are not reportable. The ICD-O-3 code is 9020/1. According to the WHO Classification of Tumours of the Breast and Female Genital Organs, borderline PT's are also called low grade malignant PT's.
Histology/Polyp--Colon: Which histology code is used when a colon biopsy states adenocarcinoma arising in a polyp, but the resection path states only adenocarcinoma, and does not mention arising in a polyp. See Discussion.
This scenario occurs frequently and our QC staff is divided on which code to use.
03-24-06 Rectal Polyp: Adenocarcinoma, moderately differentiated. 6-29-06 Rectum: Adenoca, MD, invades into the submucosa. No malignancy (0/15) LNs.
Use the polyp information from the biopsy and code adenocarcinoma arising in a polyp (8210, 8261 or 8263 as appropriate).
Histology (Pre-2007)--Melanoma: Is the code 8740/3 [malignant melanoma in a junctional nevus] to be used when the pathologic diagnosis is "malignant melanoma arising in a compound nevus"?
For tumors diagnosed prior to 2007:
Assign code 8720/3 [malignant melanoma, NOS] for malignant melanoma arising in a compound nevus. A compound nevus is not the same as a junctional nevus.
ICD-O-3 does not have a specific code for melanoma in a compound nevus. Assign the code for the type of melanoma specified; for example, NOS, superficial spreading, etc.
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.
