Autologous donor, stem cells

This code indicates that a patient is serving as their own donor for stem cells, which are typically harvested and then later reinfused into the same individual. This process is fundamental to autologous stem cell transplantation, where the patient's own healthy stem cells are used to replace diseased or damaged cells.

This code is used when a patient is undergoing the collection phase of their own stem cells for a future autologous transplant. It is appropriate for the donor encounter when the patient is the source of the stem cells for their own treatment.

• This code is for the donor encounter when the patient is donating to themselves.
• Do not use this code for the recipient encounter when the patient is receiving the stem cells.
• Always code the underlying condition requiring the stem cell transplant in conjunction with this code.
