If the visit happened before Oct 1, 2015, you would have to use the ICD-9 codes. If the visit happened on or after Oct 1, 2015, you would have to use the ICD-10 codes.

Z codes are used when:
(a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
(b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.

Z86.718 Personal history of other venous thrombosis and embolism would be used if the condition is no longer a current illness. There's a Code First note for this code, so you'd have to follow that guideline.

R codes are "Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified". These would be active issues. However, if there's a better code in another chapter for 'not otherwise specified', 'unknown etiology' or 'transient', that would be what you would choose instead, as you have to code to the highest degree possible.

There are guidelines at the beginning of each chapter, within each chapter, and within each code.
