Personal history of other cellular therapy

This code indicates a patient's past medical history of receiving cellular therapy other than hematopoietic stem cell transplantation. This includes various forms of cellular treatments where cells are introduced into the body to treat or prevent disease, excluding bone marrow or stem cell transplants. It signifies that the patient has undergone such a procedure in the past, and it is relevant to their current health status or ongoing care.

Use this code when documenting a patient's history of receiving cellular therapies like CAR T-cell therapy, mesenchymal stem cell therapy for non-hematopoietic conditions, or other specialized cell-based treatments. It is appropriate when the cellular therapy is no longer active but remains a significant part of the patient's medical record, influencing future treatment decisions or surveillance. This code should be assigned as a secondary diagnosis when the history is pertinent to the current encounter.

• Do not use this code for a history of hematopoietic stem cell transplant; use Z92.81 for that specific history.
• Ensure documentation clearly specifies "other" cellular therapy to differentiate from stem cell transplants.
• This is a history code, so it should not be used for active cellular therapy treatment or complications from current therapy.
