Scenario: Stage IV adenocarcinoma of the lung and multiple symptomatic sites of metastases:
- 11/10/2018 to 11/21/2018. Treatment to thoracic spine, Unblocked photon field, 3000 cGy in 10 fractions
- 11/12/2018 to 11/23/2018: Treatment to right femur, unblocked photon field, 3000 cGy in 10 fractions
- 11/12/2018 to 11/16/2018: Left hip treated with conformal fields designed to spare adjacent bowel, bladder, and soft tissues. 2000 cGy in 5 equal fractions.
- 11/12/2018 to 11/16/2018: Right humerus, open square field, 2000cGy in 5 equal fractions
Question: How do you code the Total Dose Field [total cumulative radiation dose administered to the patient across all phases during the first course of treatment.]?
Rationale:Record the maximum dose to first volume/phase. Do not add doses to different treatment volumes.
