Thrombosis due to internal orthopedic prosth dev/grft, subs

This code signifies a blood clot formation that has occurred as a complication of an internal orthopedic device, implant, or graft. It indicates that the patient is receiving ongoing care for this thrombosis following its initial treatment.

Apply this code when a patient presents for follow-up, monitoring, or further treatment of a previously diagnosed thrombosis directly attributed to an orthopedic prosthetic device. This includes scenarios where the patient is on anticoagulation therapy or undergoing evaluation for persistent symptoms related to the clot.

• Always use an additional code to identify the specific type of thrombosis (e.g., DVT, pulmonary embolism).
• Ensure documentation clearly links the thrombosis to the orthopedic device and indicates the encounter is not for the initial treatment.
• Verify the encounter is for subsequent care; for initial treatment, use the "A" seventh character.
