What 38205 covers
Code 38205 represents collection of blood-derived hematopoietic progenitor cells from a donor for an allogeneic transplant. Apheresis staff collect circulating cells from the donor’s blood, commonly after mobilization, in a hospital-based collection setting under the transplant or hematology team. This is the blood collection service, not a bone marrow harvest or the recipient’s transplant procedure.
Select this code for an allogeneic blood collection, rather than an autologous collection or marrow harvest. Document the donor, collection method and date, and transplant context. Medicare pays only in specific circumstances. The 0-day global includes same-day preoperative and postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

38205 billing questions
How does 38205 differ from 38206?
38205 is for blood-derived stem cell collection from an allogeneic donor. Use 38206 for blood-derived collection for autologous transplantation.
When is 38230 used instead?
38230 describes an allogeneic bone marrow harvest. Choose 38205 when the cells are collected from blood by apheresis rather than harvested from marrow.
Does 38205 include cryopreservation?
It represents the collection service. When the collected product is also cryopreserved, 38207 may describe that separate processing service if performed and documented.
How should units be counted?
Report the service per collection, not per bag or aliquot. Documentation should identify the collection session.
Which assistant or surgeon modifiers are supported?
Assistant-at-surgery payment is allowed only with documentation of medical necessity. Co-surgeons and team surgery are not permitted, and modifier 50 is inappropriate.
Will Medicare pay for every allogeneic collection?
No. CMS lists restricted coverage: payment is limited to specific circumstances. The record should support the applicable coverage circumstances and the transplant-related collection.
