CPT® Code 85348

The CPT® Code 85348 refers to a laboratory test that measures coagulation time using methods other than those specifically defined by other codes. Coagulation time is a critical parameter in assessing the blood's ability to clot, which is essential for normal hemostasis. This test quantifies the duration, in minutes, that it takes for a blood sample to form a clot after the addition of specific reagents or under certain conditions. The measurement of coagulation time is particularly important in evaluating platelet function, which plays a vital role in the clotting process. Code 85348 is applicable when the coagulation time evaluation does not fall under the more defined categories such as Lee-White or activated coagulation time tests, which have their own specific codes. This allows for flexibility in coding when the exact method of coagulation assessment is not specified, ensuring that healthcare providers can accurately report the laboratory services rendered.
