D. It is coded as other therapy

Answer 6

B. It is coded as radiation therapy

Question 7

Hyperfractionation means

A. Beam radiation plus boost energy
B. Dose above 50 Gray
C. Smaller dose given twice daily
D. Radiation plus sensitizing chemotherapy

Answer 7

C. Smaller dose given twice daily

Question 8

A. Boron Neutron Capture Therapy
B. Radioembolization
C. Radioimmunotherapy
D. 3D conformational therapy

Answer 8

D. 3D conformational therapy

Question 9

One radiation treatment to one target volume; a radiation session.

Answer 9

Fraction

Question 10

The anatomic content being treated by radiation.

Answer 10

Target volume

Question 11

The 3-dimensional space around the target volume that is receiving doses of radiation.

Answer 11

Treatment volume

Question 12

A set of radiation treatments delivered with a specific target volume, fraction size, modality, and technique; a new one begins when any of the four parameters changes.

Answer 12

Phase

Question 13

Which phase of radiation should be coded first?

Answer 13

Phases should be coded in chronological order.

Question 14

If multiple phases of radiation start on the same date, in what order should they be coded?

Answer 14

In order from highest total dose to lowest total dose.

Question 15

If multiple phases of radiation start on the same date and they are all of equal dose, in which order are they coded?

Answer 15

In any order.

Question 16

If the patient has radiation treatment but the modality details are not available, code the modality to

Answer 16

98

Question 17

If radiation treatment combines different modalities, such as external beam and brachytherapy, can you add the doses?

Answer 17

No. Mixed modalities cannot be added together. Code total dose to 999998.

Question 18

When can you add doses of radiation across different phases?

Answer 18

Only when multiple phases are directed at the same site and use the same modality.

Question 19

If the whole pelvis is treated after a hysterectomy, how do you code the radiation site?

Answer 19

Code the site to 86, pelvis, NOS

Question 20

The isotope iridium is coded as what modality of radiation therapy?

Answer 20

Brachytherapy (HDR)

Question 21

If a patient has a total/radical mastectomy and then receives post mastectomy radiation, code the treatment site to

Answer 21

43 - the chest wall

Question 22

When the lymph nodes are the primary target volume, how do you code the draining lymph nodes field?

Answer 22

88
