Z86.71Personal history of venous thrombosis and embolism

Z86.71 is the ICD-10-CM diagnosis code for personal history of venous thrombosis and embolism. It belongs to category Z86 (personal history of certain other diseases), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within Z86.7 (personal history of diseases of the circulatory system), Z86.71 is specifically for personal history of venous thrombosis and embolism. Related codes cover thrombophlebitis (Z86.72), transient ischemic attack (TIA), and cerebral infarction without residual deficits (Z86.73), sudden cardiac arrest (Z86.74) and other diseases of the circulatory system (Z86.79).

To report this condition, pick the subcode that matches the documentation: Z86.711 (embolism) and Z86.718 (embolism).

Code first: any follow-up examination after treatment (Z09).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
