Bone marrow transplant status

This code indicates that a patient has previously undergone a bone marrow transplant, also known as a hematopoietic stem cell transplant. It signifies the patient's current health status as having a history of this significant medical procedure, regardless of the success or failure of the transplant.

Use this code for patients who have a documented history of receiving a bone marrow transplant. This status code is appropriate for follow-up visits, for patients presenting with complications related to their transplant, or when the transplant history is relevant to their current medical management.

• Always assign this code as a secondary diagnosis, as it describes a status, not an active disease.
• Do not use this code for patients currently undergoing the transplant procedure; instead, use codes for the underlying condition and procedure.
• Ensure documentation clearly states "history of bone marrow transplant" or similar phrasing to support code assignment.
