About the DG2 Code Range
The ICD-10-PCS root operation Stereotactic Radiosurgery (Code DG2) relates to targeted, high-precision radiation treatment delivered to specific endocrine system structures. It provides a noninvasive therapeutic approach that uses advanced imaging to focus radiation beams accurately on the intended body part.
Within the Radiation Therapy classification, stereotactic radiosurgery is used to treat various endocrine glands, including the Pituitary Gland, Pineal Body, Adrenal Glands, Parathyroid Glands, and Thyroid. This operation can be performed using different radiation types such as Other Photon, Particulate, or Gamma Beam. For example, code DG20JZZ specifies gamma beam radiosurgery on the pituitary gland, while DG22DZZ refers to photon radiosurgery targeting the adrenal glands. These codes distinctly capture the radiation modality and anatomical site, ensuring precise documentation of stereotactic radiosurgery procedures within the endocrine system. Accurate coding supports treatment planning and outcome tracking in radiation therapy.
