HCPCS 78227

Hepatobiliary system imaging, including gallbladder, when present; with pharmacologic intervention, including quantitative measurement(s)

AI EXPLANATION: A HIDA scan with pharmacological intervention is a specialized nuclear imaging scan of the liver, gallbladder, bile ducts, and small intestine. A healthcare provider injects a tiny amount of a radioactive tracer into a vein, followed by a medication that stimulates the gallbladder to contract. A special camera tracks the movement of the tracer through the digestive system and measures how effectively the gallbladder empties.
