Overdose of radiation given during therapy

This code signifies an adverse event where a patient receives an excessive dose of radiation during a therapeutic procedure. This can result from miscalculation, equipment malfunction, or administrative error, leading to potential tissue damage or other complications.

Apply this code when documentation clearly indicates that a patient suffered an overdose of radiation during a course of treatment, such as radiotherapy for cancer. This includes situations where the intended therapeutic effect was exceeded due to the excessive dose.

• Always sequence this code as a secondary diagnosis, following the code for the condition being treated.
• Look for documentation specifying "overdose," "excessive radiation," or "radiation toxicity due to overdose."
• Do not use for complications of properly administered radiation therapy (e.g., radiation dermatitis at expected therapeutic levels).
