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.

I would definitely inquire to the provider on the stage and site, but if you can't or do not get any additional information and that is all you have you would only be able to code L89.90 Pressure ulcer of unspecified site, unspecified stage.
You also want to additional code the BKA Z89.512 Acquired absence of left leg below knee.

If you're unable to obtain the stage of the ulcer, I would take it to L89.899. I would not take it to L89.90 because the site is specified as the BKA amputation stump.

Hope this helps!
