Scenario: Endometrioid Adenocarcinoma pT3b pN0 treated with TAH/BSO + XRT
1/7/21 to 2/11/21, Whole pelvis RT w/ 6X/IMRT, 180 cGy x 25 fx to 45 Gy.
2/13/21 to 2/18/21, Vaginal cuff HDR brachytherapy via Ir-192 seeds, 600 cGy x 2 fx for a total of 1200 cGy.
Question 1: How would you code Phase I Volume?
- 71 Uterus or Cervix
- 86 Pelvis Nos
Answer: 71 Uterus or Cervix
Rationale: CTR Guide to Coding Radiation Therapy Treatment in the STORE Version 3.0 February 2021
Example #16 Gyn-Brachytherapy + External Beam Radiotherapy (EBRT) . If a primary site in the pelvic region is surgically resected, code the primary irradiated volume to the primary site
Question 2: How would you code Phase I Radiation to Draining Lymph Nodes?
- 00 No radiation treatment to draining lymph nodes
- 06 Pelvic lymph nodes
Answer: 06 Pelvic Lymph nodes
Rationale: STORE Phase I-II-III Radiation to Draining Lymph Nodes page 267 Example: Prostate cancer patient declines surgery for management of his prostate cancer, and opts for EBRT. The treatment summary states that pelvis/prostate were targeted on phase 1 with 180 cGy X 25 fx= 45 Gy. Record Phase I Radiation to Draining Lymph Nodes as 06 because when the pelvis is specifically mentioned in the treatment summary, we can assume that regional lymph nodes were targeted.

When a region like the pelvis is treated, code the primary site. Pelvic lymph nodes are identified as a target in Rad to Nodes Example #6, #8, #16, #24, #26
