Unspecified donor, stem cells

This code indicates that a patient has received stem cells from a donor whose specific identity or relationship to the recipient is not documented. It signifies a stem cell transplant where the donor type (e.g., autologous, allogeneic, related, unrelated) remains unknown or unrecorded in the medical record.

Use this code when documentation confirms a stem cell transplant occurred, but the medical record lacks sufficient detail to specify the donor type. This might occur in cases of incomplete transfer records, historical data, or when the donor information was not explicitly captured.

• Only use this code when more specific donor codes (e.g., Z52.01, Z52.09) cannot be assigned due to insufficient documentation.
• Query the provider if the donor type is unclear to determine if a more precise code can be used.
• This code should be a last resort when all efforts to identify the donor type have failed.
