Report Question ID Question Discussion Answer Year
20000502 EOD-Extension/EOD-Lymph Nodes: Can the AJCC TNM/Stage be used to help code these fields when there is limited text information in the medical record that describes the tumor involvement?

For cases diagnosed 1998-2003:

Yes, this staging information can be used to help code the SEER EOD fields but only if a physician does the TNM/Stage at the time of diagnosis and there is limited text information that describes tumor involvement.

 2000
20000551 Primary Site--Breast: What subsite code should be used for a diagnosis of "inflammatory carcinoma"? Code the Primary Site field to C50.9 [Breast, NOS] for a breast primary presenting with inflammatory cancer unless there is a palpable mass within the breast. If there is a palpable mass, code the primary site to the position of the mass. 2000
20000556 Surgery of Primary Site--Cervix: How is this field coded for a cervix primary when a biopsy removes the entire tumor? See discussion. Path from biopsy shows "severe dysplasia--CIN III" and the report from an endocervical curettage (ECC) is "chronic cervicitis"? For cases diagnosed 1998 and later: Code the Surgery of Primary Site field to 25 [Dilatation and curettage; endocervical curettage (for in situ only)]. 2000
20000450 Primary Site--Esophagus: What is the difference between C15.5 [Lower third of esophagus] and C15.2 [Abdominal esophagus]? These descriptions represent the use of two different ways the esophagus can be divided anatomically. The two different systems used are illustrated in the SEER Self Instruction Manual for Tumor Registrars: Book 4. Assign the primary site code that describes the location of the tumor in the same way the tumor's location is described in the medical record. 2000
20000249

EOD-Lymph Nodes--Melanoma: Should we assume that positive lymph nodes are regional if the primary site for a melanoma is not identified (i.e., C449)?

For cases diagnosed 1998-2003: Code the EOD-Lymph Nodes field to 8 [Lymph Nodes, NOS].

 2000
20000546 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.

 2000
20000553 EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?

For cases diagnosed 1998-2003:

EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.

Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.

20000431

Surgery Fields--Multiple sites: What code is used to represent these fields for the following surgical procedures?

1. Tongue, NOS - Hemiglossectomy with lymph node dissection

2. Choroid - Eye enucleation

3. Vulva, NOS - Vulvectomy with bilateral lymph node dissection

4. Gallbladder - Cholecystectomy

5. Lung - Laminectomy with partial removal of tumor

For cases diagnosed 1/1/03 and later:

1. Code Surgery of Primary Site to 30 and Scope of Regional Lymph Node Surgery to 3.

2. Code Surgery of Primary Site to 41.

3. Code Surgery of Primary Site to 40 and Scope of Regional Lymph Node Surgery to 3.

4. Code Surgery of Primary Site to 40.

5. Code Surgical Procedure of Other Site to 4.

 2000
20000469 Reason for No Cancer-Directed Surgery--Lung: How do you code this field for a lung primary that presents with metastasis to the bone and brain in which the oncologist's treatment plan includes only radiation and chemotherapy? Code the Reason for No Cancer-Directed Surgery field to 1 [Cancer-Directed Surgery Not Recommended]. 2000
20000270

EOD-Lymph Nodes--Lung: What code is used to represent this field when the only information is a description of:

1. "hilar mass"

2. "mediastinal mass"

3. "enlarged" or "greater than 1 cm" used to describe any of the lymph nodes listed under code 2 in the EOD Lymph Nodes field?

For cases diagnosed 1998-2003:

Code EOD-Lymph Nodes fields as follows for the examples given:

1) 9 [Unknown; not stated] for a "hilar mass"

2) 2 [Mediastinal] for a "mediastinal mass"

3) 2 [Mediastinal] for "enlarged" or "greater than 1 cm," if used to describe any of the named lymph nodes listed under code 2 in the EOD-Lymph Nodes field.
