About the DM2 Code Range
Stereotactic Radiosurgery (code root DM2) in the ICD-10-PCS system refers to a specialized form of radiation therapy that delivers precisely targeted radiation doses to a specific body part, here focused on the breast.
This Radiation Therapy root operation uses advanced imaging and computer guidance to direct different radiation types—such as Other Photon, Particulate, or Gamma Beam—to treat breast tissue with high accuracy, minimizing damage to surrounding healthy tissue. The provided examples illustrate this technique applied to the Left Breast (codes DM20DZZ, DM20HZZ, DM20JZZ) and Right Breast (codes DM21DZZ, DM21HZZ, DM21JZZ). Each code specifies the type of radiation beam used, reflecting detailed procedural documentation essential for patient care and billing. Using these ICD-10-PCS stereotactic radiosurgery codes accurately captures this targeted radiation treatment approach within breast cancer management or other breast conditions requiring precise radiation therapy.
