Thrombosis due to genitourinary prosth dev/grft, subs

This code signifies the development of a blood clot (thrombosis) specifically attributed to the presence of a prosthetic device, implant, or graft within the genitourinary system. It indicates that the patient is presenting for care related to this complication following the initial encounter for the condition.

Apply this code when a patient with a genitourinary prosthetic device (e.g., urinary stent, artificial sphincter, mesh) develops thrombosis, and the encounter is for ongoing management or follow-up after the initial diagnosis. This would include situations where the patient is receiving treatment for the thrombosis or being monitored for its resolution.

• Always sequence this code after the primary diagnosis for the thrombosis itself (e.g., D68.8, other specified coagulation defects).
• Ensure documentation clearly links the thrombosis to the genitourinary prosthetic device.
• Verify that the encounter is indeed a "subsequent encounter" and not the initial diagnosis or a sequela.
