About 85396: Whole-blood clotting assay
Reports a whole-blood clotting assay, commonly viscoelastic testing, used to assess clot formation and breakdown in settings such as major bleeding or surgery.
CPT 85396 covers a clotting assay performed on whole blood, commonly a viscoelastic test such as thromboelastography. The test evaluates how a clot forms and changes over time, providing information that can help clinicians assess hemostasis. It may be used during trauma resuscitation, cardiac surgery, liver transplantation, or other episodes of significant bleeding. Testing is generally performed by a clinical laboratory or point-of-care team, with results used by the treating clinician to guide management.
Report 85396 when the documented service is a whole-blood clotting assay, rather than a plasma coagulation test or a different specifically defined clotting-time test. The record should identify the whole-blood assay performed, its clinical purpose, and the resulting findings. Choose the code based on the actual test method and service, not solely on the clinical setting or the fact that a result was used to guide transfusion. The CMS physician fee schedule record assigns work and practice-expense relative value units to this code.

85396 billing questions
When should 85396 be selected instead of an activated clotting-time code?
Use 85396 for the documented whole-blood clotting assay, commonly a viscoelastic assay. Use an activated clotting-time code when that specific activated clotting-time test was performed.
Is thromboelastography a typical example of 85396?
Yes. Thromboelastography is a commonly recognized example of a whole-blood clotting assay reported with this code.
What documentation supports reporting 85396?
Document the whole-blood assay or method performed, the clinical indication, and the findings. The record should support that the service was a clotting assay rather than a different coagulation test.
Can 85396 be used for a plasma-based coagulation test?
No. The code identifies a whole-blood clotting assay; select a code that describes the actual plasma-based test performed.
Is 85396 interchangeable with activated clotting time by another method?
No. Activated clotting-time codes describe that specific test, while 85396 describes a whole-blood clotting assay such as a viscoelastic assay.
