Description:
Records the exact number of regional nodes examined by the pathologist and found to contain metastases. Beginning with tumors diagnosed on or after January 1, 2004, this item is a component of the Collaborative Stage system. For tumors diagnosed from 1988 through 2003, this item was part of the 10-digit EOD [779], detailed site-specific codes for anatomic EOD.
Rationale:
This data item is necessary for pathologic staging, and it serves as a quality measure for pathology reports and the extent of the surgical evaluation and treatment of the patient.
Format:
Right justified, zero filled
Item Data Type:
digits
Allowable Values
00-90, 95, 97-99
Codes:
00 |
All nodes examined are negative |
|---|---|
01-89 |
1-89 nodes are positive (code exact number of nodes positive) |
90 |
90 or more nodes are positive |
95 |
Positive aspiration of lymph node(s) was performed |
97 |
Positive nodes are documented, but the number is unspecified |
98 |
No nodes were examined |
99 |
It is unknown whether nodes are positive; not applicable; not stated in patient record |
