CPT Code Overview
CPT code 86701 is used to report the laboratory test for Hepatitis A antibody (IgM). This test is essential for detecting acute Hepatitis A infection, providing critical information for diagnosis and patient management. The service is classified as a laboratory procedure and is typically performed in an independent laboratory setting, designated as Place of Service 81. The test plays a key role in identifying recent exposure to the Hepatitis A virus and guiding clinical decisions.
Clinical & Coding Specifications
Clinical Context
A patient presents to their primary care provider with symptoms such as nausea, vomiting, fever, and elevated liver enzymes. The provider suspects acute viral hepatitis and orders laboratory testing to determine the cause. The independent laboratory collects a blood sample and performs the Hepatitis A antibody (IgM) test (86701) to detect recent infection. The results assist the provider in confirming or ruling out acute Hepatitis A, guiding further management and infection control measures.
