NAACCR | Laterality | yes |
Field Length: 1
Enter the one digit code which describes this primary with regard to involvement of one or both sides of paired organs (see list below).
Code | Description |
---|---|
0 | Not paired |
1 | Right origin |
2 | Left origin |
3 | Only one side involved, right or left origin unspecified |
4 | Bilateral, side of origin unknown or single primary (i.e. bilateral Wilms’ tumors) |
5 | Midline origin |
9 | Paired, but no information concerning laterality |
Coding Instructions
1. Use code 0 (not a paired organ) for an unknown primary site (C80.9).
2. Code laterality using codes 1-9 for all of the sites listed below. Note: Laterality may be coded for sites other than those listed below.
3. Code the side where the primary tumor originated.
a. Assign code 3 if the laterality is not known but the tumor is confined to a single side of the paired organ.
Example: Pathology report: Patient has a 2cm carcinoma in the upper pole of the kidney. Code laterality as 3 because there is documentation that the disease exists in only one kidney, but it is unknown if the disease originated in the right or left kidney.
4. Code 4 is seldom used EXCEPT for the following diseases:
i. Both ovaries involved simultaneously, single histology
ii. Bilateral retinoblastomas
iii. Bilateral Wilms’ tumor
iv. If both lungs have nodules or tumors and the lung of origin is not known
5. Assign code 5 when the tumor originates in the midline of a site listed in 5.a.
a. C700, C710 - C714, C722 - C725, C443, C445
Example 1:Patient has an excision of a melanoma located just above the umbilicus.
Example 2:Patient has a midline meningioma of the cerebral meninges.
6. Assign code 9 when:
a. The neoplasm originated in a paired site and
1. Laterality is unknown
AND
2. There is no statement that only one side of the paired organ is involved.
Example 1: Admitting history says patient was diagnosed with lung cancer based on positive sputum cytology. Patient is treated for painful bony metastases. There is no information about laterality in the diagnosis of this lung cancer.
Example 2: Widely metastatic ovarian carcinoma surgically debulked. Ovaries could not be identified in the specimen.
b. Laterality is unknown for a death certificate only (DCO)case with primary site C079 -C081, C090-C091, C098-C099, C301, C310, C312, C341-C349, C384, C400-C403, C441-C443, C445-C447, C471-C472, C491-C492, C500-C509, C569, C570, C620-C629 C630-C631, C649, C659, C669, C690-C699, C700, C710-C714, C722-C725, C740-C749, or C754.
