Blood-sampling as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure

Y84.7 (“Blood-sampling as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure”) is a diagnosis code that identifies a specific condition, injury, or finding on a medical claim in the ICD-10-CM code set. Whether it is billed — and whether a payer covers it — depends on the clinical setting, documentation, and plan rules.
