About Y64.0

Y64.0 is the ICD-10-CM diagnosis code for contaminated medical or biological substance, transfused or infused. It belongs to category Y64 (contaminated medical or biological substances), 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 Y64 (contaminated medical or biological substances), Y64.0 is specifically for contaminated medical or biological substance, transfused or infused. Related codes cover substance, injected or used for immunization (Y64.1), substance administered by other means (Y64.8) and substance administered by unspecified means (Y64.9).

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 E875.0 (contaminated substance transfused or infused).
