Transplanted organ and tissue status, unspecified

This code indicates that a patient has a history of an organ or tissue transplant, but the specific type of transplanted organ or tissue is not documented or is unknown. It signifies the presence of a transplant without further detail regarding the anatomical site or nature of the graft.

This code is appropriate when a patient's medical record clearly states a history of a transplant, but lacks information to assign a more specific Z94 code (e.g., Z94.0 for kidney transplant, Z94.1 for heart transplant). It can be used when reviewing historical records or when the transplant type is not relevant to the current encounter's primary diagnosis and is not further investigated.

• Always strive for a more specific Z94 code if the type of transplanted organ or tissue is documented.
• Do not use this code if the transplant status is unknown or if there is no evidence of a transplant.
• This code is typically a secondary diagnosis, providing important patient history.
