Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Z94: its own notes plus those printed at block Z77-Z99 and Chapter 21. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • organ or tissue replaced by heterogenous or homogenous transplant

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • complications of transplanted organ or tissue - see Alphabetical Index

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

  • presence of vascular grafts (Z95.-)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

From Block Z77-Z99 Persons with potential health hazards related to family and personal history and certain conditions influencing health status applies to 567 codes
  • any follow-up examination (Z08-Z09)

Notes

General instructions on how these codes are used.

From Chapter 21 (Z00-Z99) Factors influencing health status and contact with health services applies to 1,425 codes
  • 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.

Patient EducationClinical

Organ Transplantation

You may need an organ transplant if one of your organs has failed. This can happen because of illness or injury. When you have an organ transplant, doctors remove an organ from another person and place it in your body. The organ may come from a living donor or a donor who has died.
