Tissue typing is reported using code range __________.

The code range that pertains to tissue typing is 86805-86849. This range specifically covers various serological tests used for tissue typing, which is crucial in transplant medicine to ensure compatibility between donors and recipients. This includes testing for human leukocyte antigens (HLA) and other markers that play a vital role in determining tissue compatibility.

The relevance of this code range stems from its focus on immunology and transfusion medicine, where accurate tissue typing can significantly impact patient outcomes during procedures like organ transplants. By using the codes in this range, healthcare providers can appropriately document and bill for the laboratory processing and analysis necessary to match donations with recipients safely.

The other ranges provided do not pertain to tissue typing specifically; they encompass different areas of laboratory testing, such as microbiology or cytopathology, which do not include the necessary codes for reporting tissue typing services.
