20000530 Histology (Pre-2007)/Grade, Differentiation--Brain and CNS: What code is used to represent the histology and grade for "WHO-II astrocytoma, grade II" of the brain when the WHO-II classification is different from the classification systems previously used? See discussion. According to the WHO-I classification system, this is a moderately anaplastic astrocytoma. According to the Duke criteria, this is an astrocytoma. By Dauma-Dupont criteria, this is a grade 2 astrocytoma.

For tumors diagnosed prior to 2007:

Code the Histology and Grade, Differentiation fields to 9401/34 [anaplastic astrocytoma].

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.

20000518 Histology (Pre-2007): What code is used to represent the histology "papillary adenocarcinoma: mixed serous, endometrioid and mucinous subtypes"? See discussion. Example: Fallopian tube right (salpingectomy): Primary adenocarcinoma: mixed serous, endometrioid, and mucinous subtypes

For tumors diagnosed prior to 2007:

For cases diagnosed on or after 1/1/98: Code the Histology field to 8323/3 [adenocarcinoma, mixed cell]. The case is coded using the mixed histology rule A in the Coding Complex Morph Dx's.

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.

 2000
20000430 Histology (Pre-2007)--Colon: What code is used to represent histology when the surgeon describes a sessile polyp and the final path diagnosis is stated as: "Rectal sessile polyp: Invasive moderately differentiated adenocarcinoma" (pathologist does not state that it is "arising in a sessile polyp")?

For tumors diagnosed prior to 2007:

Code the Histology field to 8210/3 [adenocarcinoma arising in a polyp]. The structure in which this adenocarcinoma is arising, is a polyp.

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.

20000508 EOD-Extension--Cervix: Should this field be coded to 11 [minimal microscopic stromal invasion] or 12 [microinvasion] when there is only a statement of "microinvasion" but no measurements describing the level of involvement given?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 12 [microinvasion] when there are no depth of invasion measurements given.

Code the EOD-Extension field to 11 [minimal microscopic stromal invasion] when there is a statement of "minimal STROMAL invasion."

EOD-Extension--Head & Neck (Larynx): When "fixed" is stated for a larynx primary does it specifically have to say that it is the vocal cord that is fixed? Are the terms "fixed" and "immobile" synonymous? Should these cases be coded to 40 rather than 35? See discussion.

1. The tumor is fixed, the arytenoid on left side is fixed and the right arytenoid is partially fixed. Palpation of the tumor reveals it to be fixed in the larynx. T3 N0 M0 Stage III.

2. Erythema and swelling of right false cord with bulging and immobility. Left cord moves normally. T3 N0 M0 Stage III.

For cases diagnosed 1998-2003:

Code the EOD-Extension field for both cases to 40 [Tumor limited to larynx WITH vocal cord fixation]. Code 35 [Impaired vocal cord mobility] implies that mobility is diminished in strength and/or quality but is not rigid. Impaired mobility is a T2 tumor. Because the second case is T3, the physician implies he/she is using the term "immobility" to describe complete fixation.

Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?

Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:

1. Induction (remission induction)

2. CNS preventive therapy

3. Consolidation/intensification

4. Maintenance

20000852 Histology (Pre-2007)/Grade, Differentiation: What code is used to represent the histology "cystadenocarcinoma with multiple foci of high grade anaplastic and undifferentiated sarcoma"? See discussion. The case was presented at tumor conference. The physicians indicated that the patient would not have the same disease course as a patient with cystadenocarcinoma of the ovary. The physicians advised the use of a mixed histology code. However, there is no appropriate mixed histology code for cystadenocarcinoma, anaplastic carcinoma, and sarcoma. It doesn't seem as though these cases should be grouped and analyzed with cases having a single histology of cystadenocarcinoma.

For tumors diagnosed prior to 2007:

Code the Histology and Grade, Differentiation fields to 8440/34 [cystadenocarcinoma, anaplastic] because a combination code for the specified histologic type does not exist.

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.

 2000
20000476 Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)? For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy]. 2000
20000269

Multiple Primaries (Pre-2007): Is an in situ tumor followed by another in situ tumor in the same location a new primary? See discussion.

Example: Six months after an in situ lesion was excised from the buccal mucosa, another in situ lesion was excised from the same area of the buccal mucosa with no mention of it being recurrent.

For tumors diagnosed prior to 2007:

Code as a second primary if the second in situ tumor occurred more than 2 months after the first, and it is not referred to as recurrent by the clinician or pathologist. There are no special rules for determining the number of primaries when an in situ lesion follows an in situ.

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.

20000260 EOD-Size of Primary Tumor--Breast: When the pathology report does not specify dimensions for the invasive component, how is tumor size coded? See discussion. In some cases the tumor has both invasive and in situ components. The pathologist sometimes does not report the size for the invasive portion of the tumor. In most cases, the invasive portion is described as a percentage of the tumor mass. From January 1, 1998 and forward: Follow the Revised Breast EOD instructions. If the size of the invasive component is not given, record the size of the entire tumor in the EOD-Size of Primary Tumor field. Assign the appropriate EOD-Extension code for the situation. 2000
