Rad--Regional RX Modality

IDENTIFIERS

CCR ID	NAACCR ID
E1356	1570

DESCRIPTION

Records the dominant modality of radiation therapy used to deliver the most clinically significant regional dose to the primary volume of interest during the first course of treatment.

Radiation treatment is frequently delivered in two or more phases which can be summarized as “regional” and “boost” treatments. To evaluate patterns of radiation oncology care, it is necessary to know which radiation resources were employed in the delivery of therapy. For outcomes analysis, the modalities used for each of these phases can be very important.

If the new case record version is A or later, then load and right-justify and zero-fill.

UPDATE

Tumor Level

New Case Consolidation

If both of the following conditions are true:

1. - the admission and tumor’s Rad Regional RX Modality codes are different
  - any of the combinations listed in the following table are found:

Admission level value =	Tumor level value =
20- 62	00, 98, 99, blank
21- 40	20
31 or 32	21 - 30
42- 43	41
51- 55	50
61- 62	60
98	00, 99, blank
00	99 or blank
99	blank

Then automatically update the tumor’s Rad Regional RX Modality code with the admission’s corresponding code.

Otherwise, if both of the following conditions are true:

- the admission and tumor’s Rad Regional RX Modality codes are different
- Any combination listed in the following table are found:

Admission level value =	Tumor level value =
20, 41, 50 or 60	20, 41, 50 or 60
21 – 40, 42 – 43, 51 – 55 or 61 – 62	21 – 40, 42 – 43, 51 – 55 or 61 –62
42 – 43, 51 – 55, 61 – 62	20
21 – 40, 51 – 55, 61 – 62	41
21 – 40, 42 – 43, 61 – 62	50
21 – 40, 42 – 43, 51 – 55	60
41	21 - 40, 51 – 55, 61 – 62
50	21 – 40, 42 – 43, 61 – 62
60	21 – 40, 42 – 43, 51 – 55
Any value	80 or 85

Then list for review
