CPT® Code 83904

Deleted

The CPT® Code 83904 refers to a specific molecular diagnostic procedure that focuses on the identification of mutations through DNA sequencing. This process involves analyzing a tissue sample to detect any alterations in the DNA sequence that may be indicative of a disease or disorder. The term "mutation identification by sequencing" signifies that the procedure is designed to pinpoint specific changes in the genetic material, which can be crucial for diagnosing various medical conditions. The phrase "single segment, each segment" indicates that the analysis is performed on one segment of DNA at a time, allowing for a detailed examination of specific areas of interest within the genetic code. This targeted approach is essential for understanding the genetic underpinnings of certain diseases, enabling healthcare providers to make informed decisions regarding patient care and treatment options.
