- The number of treatments or fractions will typically be found in the radiation oncologist’s summary letter for the first course of treatment. Determination of the exact number of treatments or fractions delivered to the patient may require assistance from the radiation oncologist for consistent coding.
- Although a treatment session may include several treatment portals delivered within a relatively confined period of time—usually a few minutes—it is still considered one session.
- The total number of treatment sessions (fractions) is the sum of the number of fractions of regional treatment and the number of fractions of boost treatment.
- Count brachytherapy or implants as a single treatment or fraction.
