2025 CPT code 85362
(Active) Effective Date: N/A Revision Date: N/A Pathology and Laboratory Procedures - Fibrinogen degradation products Hematology and Coagulation Procedures Feed
Semiquantitative slide agglutination test for fibrinogen degradation products (FDP) or fibrinogen split products (FSP).
Modifiers may be applicable depending on the circumstances of service.Consult the CPT manual and payer guidelines for appropriate modifier usage.
Medical necessity for CPT code 85362 is established when the physician orders the test to evaluate for DIC, congenital afibrinogenemia, or other conditions associated with abnormal fibrinogen degradation.The test may also be medically necessary for monitoring treatment response in patients with these conditions.
The clinical responsibility lies with the laboratory analyst who performs all technical aspects of the test, including specimen handling, reagent preparation, and interpretation of the agglutination results.

In simple words: This lab test measures the level of broken-down fibrinogen in your blood. Fibrinogen is a protein that helps blood clot.The test uses a special technique to see how much fibrinogen has been broken down, which can help doctors diagnose certain conditions.
This CPT code (85362) represents a semiquantitative slide agglutination test used to measure fibrinogen degradation products (FDPs) or fibrinogen split products (FSPs) in a patient's sample (e.g., serum or urine).The test uses a latex agglutination method (such as the Thrombo-Wellco method) where a reagent is added to the sample on a slide. The resulting agglutination pattern provides a semi-quantitative assessment of major FDP/FSP levels. Clinicians may order this test to aid in diagnosing conditions like disseminated intravascular coagulation (DIC) or congenital afibrinogenemia, although its use is not limited to these conditions.
Example 1: A patient presents with symptoms suggestive of disseminated intravascular coagulation (DIC). The physician orders a semiquantitative FDP/FSP test (CPT code 85362) to help confirm the diagnosis and monitor treatment response., A patient with a history of bleeding disorders undergoes surgery.Post-operatively, a FDP/FSP test (CPT code 85362) is performed to evaluate for possible DIC or other clotting abnormalities., A newborn infant exhibits prolonged bleeding times.The physician orders a FDP/FSP test (CPT code 85362) as part of the diagnostic workup for congenital afibrinogenemia or other inherited clotting disorders.
** Some payers may reimburse separately for specimen collection (e.g., venipuncture).
