CPT® Code 86911

The CPT® Code 86911 refers to the process of blood typing specifically for paternity testing. This procedure involves drawing blood samples from a male, presumed to be the father, and a child to ascertain the biological relationship between them. The primary objective of this test is to identify specific blood antibodies present in the samples, which are then compared to determine the likelihood that the male is indeed the biological father of the child. The results of this analysis yield a statistical probability, providing evidence that can support or refute claims of paternity. In cases where the initial test results are inconclusive, this code is applicable for further testing, which may involve additional antigen systems to enhance the accuracy of the paternity determination. This procedure is critical in legal contexts, such as custody disputes or child support cases, where establishing paternity is essential.
