Abnormal coagulation profile

This code signifies laboratory findings indicating a deviation from normal blood clotting parameters. It encompasses various irregularities in coagulation tests, such as prothrombin time (PT), activated partial thromboplastin time (aPTT), or international normalized ratio (INR), that are not yet diagnosed as a specific coagulation disorder.

Apply this code when documentation specifies abnormal results from a coagulation profile without a definitive diagnosis of a specific bleeding or clotting disorder. This is often used for initial abnormal lab findings that require further investigation or monitoring. Support for this code comes from laboratory reports showing out-of-range coagulation values.

• Do not use this code if a specific coagulation defect (e.g., hemophilia, von Willebrand disease) has been diagnosed; instead, code the specific D68.- condition.
• Ensure the documentation clearly states "abnormal coagulation profile" or lists specific abnormal coagulation test results without a more definitive diagnosis.
• This code is often a temporary diagnosis while awaiting further workup to identify the underlying cause of the coagulation abnormality.
