Y84: Other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure

Y84.2: Radiological procedure and radiotherapy

Radiological procedures and radiotherapy are medical techniques that use radiation, such as X-rays, CT scans, or radiotherapy, to visualize, diagnose or treat illnesses. Radiological procedures enable doctors to examine an area of the patient's body in detail by creating images of the inside of the body. This can be invaluable in discovering abnormalities, such as tumors or bone fractures. On the other hand, radiotherapy is a type of treatment that uses high-energy radiation to destroy malignant cells and shrink tumors. In both cases, the radiation used is carefully controlled and monitored to ensure it is safe for patients. However, despite these precautions, there can sometimes be side effects or complications associated with these procedures. These may result from the procedure itself or from the radiation used and can range from minor, temporary issues like skin redness to more major problems.
