Coding Guidelines
Factors influencing health status and contact with health services (Z00-Z99)
Note: Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
(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.

Z86.2 is personal history of diseases of the blood and blood forming organs and certain disorders involving immune mechanism. then states conditions classifiable to D50-D89

VWD dx code is D68.0

That would be my best guess.

Why are you coding "history of" for this disease? It's a life-long condition with no cure, which is why I'm asking.

Only because the physician has "hx of... and I am unfamiliar with that condtion. I'm helping a friend so it's not my expertise.

Gotcha. If the condition is a factor in an encounter, you'd code for it. I believe what the previous poster mentioned is correct; D68.0. It's a blood clotting disorder, so it could very easily impact a ton of other conditions or problems. The sequencing would depend on the specifics of the encounter.
