Other thrombophilia

This code signifies a hereditary or acquired predisposition to thrombosis that is not specified elsewhere. It indicates a hypercoagulable state due to various factors, leading to an increased risk of blood clot formation. This condition can manifest as venous or arterial thromboses.

Use this code when documentation specifies a thrombophilia that doesn't fit more specific ICD-10-CM codes, such as Factor V Leiden, Prothrombin gene mutation, or Antiphospholipid syndrome. This code is appropriate when the type of thrombophilia is known but lacks a dedicated code, or when the provider documents "other thrombophilia."

• Ensure the medical record clearly states "other thrombophilia" or a specific type not otherwise classified.
• Avoid using this code if a more specific thrombophilia code (e.g., D68.51 for Activated protein C resistance) is available and documented.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is a thrombotic event (e.g., deep vein thrombosis, pulmonary embolism) caused by the thrombophilia.
