Y63: Failure in dosage during surgical and medical care

Y63.2: Overdose of radiation given during therapy

Overdose of radiation given during therapy refers to an incident where a patient receives a higher dose of radiation than what was prescribed during their radiotherapy treatment. This condition can occur due to a range of factors such as human error, malfunction of therapy equipment, or misunderstanding of the prescribed radiation dose. Symptoms may vary depending on the area exposed and severity of the overdose, but can include skin redness, dryness, swelling, and tissue damage, potentially leading to loss of function in the affected area. The condition may also accelerate the progression of secondary diseases such as radiation-induced cancers. The tissues and organs more susceptible to damage are those that have been directly exposed to the overdose of radiation. Radiotoxicity, the quality of being poisonous or harmful when irradiated, plays a significant role in the severity of complications.
