The Reptilase test, identified by CPT® Code 85635, is a specialized laboratory procedure utilized to assess the clotting time of blood. This test is particularly significant in the context of coagulation studies, as it serves as a follow-up to the thrombin time test. The primary purpose of the Reptilase test is to determine whether heparin is influencing the clotting process, which can lead to prolonged clotting times. In cases where heparin is present, the Reptilase test typically yields normal results, indicating that the clotting mechanism is functioning properly despite the presence of heparin. Conversely, if the results show a prolonged clotting time, this may suggest underlying issues such as a deficiency in fibrinogen, abnormalities in fibrinogen due to liver disease, or the presence of lupus anticoagulants in the plasma. The procedure involves the addition of reptilase to citrated blood plasma, followed by the measurement of the rate at which fibrin clots form, providing critical information for diagnosing and managing coagulation disorders.

The Reptilase test is indicated for several specific clinical scenarios, particularly in the evaluation of coagulation disorders. The following conditions may warrant the performance of this test:
The Reptilase test involves a series of precise procedural steps to ensure accurate measurement of clotting time. The following outlines the key steps involved in the procedure:
After the Reptilase test is completed, the results are analyzed and interpreted by a qualified healthcare professional. The expected recovery from the procedure is immediate, as it is a laboratory test that does not require any invasive intervention. Patients may resume normal activities following the blood draw. It is important for healthcare providers to communicate the results to the patient and discuss any necessary follow-up actions based on the findings, particularly if abnormalities are detected that may indicate underlying coagulation disorders.

| 90 | Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number. | 91 | Repeat clinical diagnostic laboratory test: in the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. note: this modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. this modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). this modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient. | GA | Waiver of liability statement issued as required by payer policy, individual case |
