Number of Positive Pelvic Nodes

Description

Number of Positive Pelvic Nodes is the number of positive nodes based on pelvic nodal dissection. For the Corpus schemas (3) and the Cervix Sarcoma schema, there are 4 data items that record information on the number of positive and examined para-aortic and pelvic lymph nodes. These related data items should be coded from the same procedure * 3899: Number of Examined Para-Aortic Nodes * 3900: Number of Examined Pelvic Nodes * 3901: Number of Positive Para-Aortic Nodes * 3902: Number of Positive Pelvic Nodes

Rationale

Number of Positive Pelvic Nodes is the number of positive nodes based on pelvic nodal dissection.

Additional Info

**Source documents:** pathology report, imaging reports, physical exam, other statements in medical record

Notes

**Note 1:** **Physician Statement** * Physician statement of positive pelvic nodes can be used to code this data item when no other information is available. **Note 2:** **Pelvic lymph nodes** * Iliac, NOS * Common * External * Internal (hypogastric) (obturator) * Paracervical * Parametrial * Pelvic, NOS * Sacral, NOS * Lateral (laterosacral) * Middle (promontorial) (Gerota’s node) * Uterosacral **Note 3:** **Isolated tumor cells** * For this data item, do not include isolated tumor cells (ITCs). **Note 4:** **Micrometastasis and macrometastasis** * Micrometastasis and macrometastasis may be listed separately on the pathology report. Add these two together to get the total number of positive nodes. **Note 5:** **Related data item** * The number of examined pelvic nodes is recorded in the related data item 3900: Number of Examined Pelvic Nodes.

Coding Guidelines

**1)** Record the number of positive pelvic lymph nodes documented in the medical record. * Number of nodes positive must ALWAYS be less than or equal to number of nodes examined **2)** Record the number of positive pelvic lymph nodes documented in the medical record. **3)** **Code 00** for when there are no positive nodes **4)** **Code 01-99** for the exact number of positive nodes **5)** **Code X1** for 100 or more positive nodes **6)** **Code X2** for positive nodes, but unknown how many **7)** **Code X6** if only a FNA or core biopsy is done, and it is positive **8)** **Code X9** when * If only a FNA or core biopsy is done, and it is negative * Not documented in the medical record * Pelvic lymph nodes not evaluated (assessed) * No lymph nodes removed * Unknown if Pelvic lymph nodes evaluated (assessed)
Code Description
00 All pelvic nodes examined negative
01-99 1 - 99 pelvic nodes positive
(Exact number of nodes positive)
X1 100 or more pelvic nodes positive
X2 Positive pelvic nodes identified; number unknown
X6 Positive aspiration or core biopsy of pelvic lymph node(s)
X8 Not applicable: Information not collected for this case
(If this item is required by your standard setter, use of code X8 will result in an edit error.)
X9 Not documented in medical record
Cannot be determined, indeterminate if positive pelvic nodes present
No lymph nodes removed
Pelvic lymph nodes not assessed or unknown if assessed
