ICD-10 Code D68.6 – Other thrombophilia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D68.6 – Other thrombophilia
What it is
D68.6 identifies thrombophilia, a tendency to form abnormal blood clots. Use it when documentation names an inherited or acquired clotting disorder that does not fit a more specific ICD-10 code.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe recurrent venous thromboembolism, family history of clotting, or a known hypercoagulable state confirmed by provider assessment.
When to use this code
Use D68.6 when the provider documents other thrombophilia, hypercoagulability, or an unspecified clotting tendency. It may apply after evaluation for recurrent thrombosis or when a specific thrombophilia is not otherwise classified. Check documentation for the exact disorder and any underlying cause.
Do not use for
Do not use this code for acute thrombosis, embolism, or coagulation defects that have a different specific ICD-10 code. If the chart names a more precise thrombophilia, code that diagnosis instead.
Coding tip
Code the documented thrombophilia diagnosis, not just a history of clotting, and verify whether the provider identified a specific inherited or acquired cause.
