Y63.3Inadvertent exposure of patient to radiation during medical care

Y63.3 is the ICD-10-CM diagnosis code for Inadvertent exposure of patient to radiation during medical care. It belongs to category Y63 (failure in dosage during surgical and medical care), block Y62-Y69 (misadventures to patients during surgical and medical care) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Y63 (failure in dosage during surgical and medical care), Y63.3 is specifically for Inadvertent exposure of patient to radiation during medical care. Related codes cover excessive amount of blood or other fluid given during transfusion or infusion (Y63.0), Incorrect dilution of fluid used during infusion (Y63.1), Overdose of radiation given during therapy (Y63.2), failure in dosage in electroshock or insulin-shock therapy (Y63.4), inappropriate temperature in local application and packing (Y63.5), underdosing and nonadministration of necessary drug, medicament or biological substance (Y63.6), failure in dosage during other surgical and medical care (Y63.8) and failure in dosage during unspecified surgical and medical care (Y63.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as E873.3 (Inadvertent exposure of patient to radiation during medical care).
