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].
EOD-Extension--Lymphoma: What code is used to represent a non-Hodgkin lymphoma presenting with involvement of an extralymphatic organ and lymph nodes on the opposite side of the diaphragm?
For cases diagnosed 1998-2003: Code the EOD-Extension field to 31 [30 + localized involvement of an extralymphatic organ or site; Stage III E].
EOD-Clinical Extension--Prostate: In the SEER EOD manual, there is a list of terms to distinguish apparent from inapparent tumor for prostate primaries. Are terms in the "maybe" category and are terms not on the list clinically inapparent or clinically apparent when there is no physician staging of the case? See discussion.
The rectal examination states that there is "asymmetrical enlargement of the prostate, firmness over the right lobe" and the physical exam impression is extensive carcinoma of right lobe. A needle biopsy of the right lobe was positive. "Enlarged" is on SEER's list of clinically inapparent terms; "asymmetrical" and "firm, NOS" are on the "maybe" list.
For cases diagnosed 1998-2003:
On the basis of the physical exam impression, code the EOD-Clinical Extension field to 20 [involvement of one lobe, NOS] for this case. Although the medical record did not provide a physician's staging of the case as clinically apparent, the physician did suspect carcinoma prior to the biopsy.
If clarifying stage information is missing and the term is in the "maybe" category or the term is not on the list, then code extension as 30 [localized, NOS] for cases that appear localized.
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.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: What codes are used to represent these fields when only a regional lymph node (positive) aspiration is performed?
For cases diagnosed 1998-2003:
With the exception of those sites/histologies that require 99 in these fields, code the Number of Regional Lymph Nodes Positive field to 97 [Positive nodes but number of positive nodes not specified]. Code the Number of Regional Lymph nodes Examined field to 95 [No regional Lymph nodes removed, but aspiration of regional Lymph nodes was performed].
Extension/Ambiguous terminology: How should the terms "entrapped by tumor" and "encased by tumor" be interpreted when coding these fields?
Each case must be reviewed in its entirety to determine the appropriate coding of these fields. However, in general the terms "entrapped" and "encased" should NOT be interpreted as involvement unless there is other clinical or pathologic evidence to support involvement.
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.
EOD-Extension--Mycosis Fungoides: Explain the difference between extension codes 25 [% of body surface not stated, no tumors] and 30 [skin involvement, NOS; extent not stated, no tumors. Localized, NOS]?
For cases diagnosed 1998-2003:
For mycosis fungoides: Use code 25 when skin involvement is present but only a general location/site is mentioned (i.e., face, legs, torso, arms).
Use code 30 when there is skin involvement but there is no mention of location/site.
EOD-Extension--Lung: If LUL mass "crosses the pleural surface" into the LLL, do we assume this represents extension to the pleura? See discussion.
9/22/93 Left upper lobe lobectomy: 3 x 3 cm mass in the periphery of the LUL near the LLL. Multiple enlarged nodes around the aortic arch and within the pulmonary fissure.
9/22/93 Pathology: Moderately differentiated Adenoca. The neoplasm does cross the pleural surface into the segment of the lower lobe. Lower margin of resection is free of neoplasm. Six lymph nodes negative for metastatic carcinoma. Tumor staged as T2N0M0 Stage Ib by physician.
Is tumor extension coded 10 [confined to one lung] or 40 [extension to pleura]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to pleura]. The tumor has penetrated (extended to) the pleura.
Surgery of Primary Site/Reconstruction-First Course--Breast: If the plan is to "reconstruct" the breast 6 months after an ipsilateral modified radical mastectomy, is the time span a problem or should it be coded in the Surgery of Primary Site field because it was planned?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 55 [Modified radical mastectomy WITHOUT removal of uninvolved contralateral breast, Implant]. The time span is not a problem as long as the reconstruction was planned as first course, which is indicated by tissue expander insertion at the time of the original surgery.
