LOINC Code 42128-9: Boost radiation treatment modality Radiation treatment

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Boost radiation treatment modality. It is commonly used with the system or sample type Radiation.Rx.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• Boost radiation treatment modality Radiation treatment
• Boost radiation treatment modality
• Records the radiation treatment-boost modality used to deliver the most clinically significant dose to the primary volume of interest during the first course of treatment. This is accomplished with external beam fields of reduced size (relative to the regional treatment fields), implants, stereotactic radiosurgery, conformal therapy, or intensity-modulated radiation therapy. External beam boosts may consist of two or more successive phases with progressively smaller fields, and they are generally coded as a single entity. This field is used with Rad--Regional RX Modality [1570]. Radiation treatment frequently is delivered in two or more phases that can be summarized as regional and boost treatments. For outcomes analysis, the modalities used for each of these phases can be very important... NAACCR Data Standards and Data Dictionary Version 11
