About the DW2 Code Range
The ICD-10-PCS root operation Stereotactic Radiosurgery (code DW2) refers to a highly precise form of radiation therapy. It targets specific anatomical regions with focused radiation beams to treat abnormalities without the need for surgical incision.
This root operation is part of the Radiation Therapy section and is used on various body regions including the Head and Neck, Chest, Abdomen, and Pelvic Region. The provided codes illustrate how stereotactic radiosurgery is delivered using different radiation types, such as Other Photon, Particulate, or Gamma Beam. For example, code DW21DZZ represents stereotactic other photon radiosurgery directed at the head and neck, while DW26JZZ indicates stereotactic gamma beam radiosurgery targeting the pelvic region. These codes emphasize the precision and varied modalities of stereotactic treatment essential for accurate procedural documentation within radiation therapy.
