Spinal surgery
About 20939: Bone marrow aspiration for spinal grafting
Reports marrow aspiration, commonly from the iliac crest, for use as graft material during spinal surgery when billed with a qualifying primary procedure.
During spinal fusion, the surgeon obtains marrow aspirate, commonly from the posterior iliac crest, to combine with graft material and support fusion. The service is performed by the operating spine surgeon in the surgical setting. It represents marrow collection for grafting, not diagnostic marrow aspiration or a code for harvesting structural or morselized bone.
Report 20939 only as an add-on with a qualifying primary spine procedure; it is not reported alone. Documentation should identify the aspiration, its grafting purpose, and the associated spinal procedure, distinguishing it from any separately documented bone harvest. CMS places payment within the primary procedure's global period, so related postoperative care follows that procedure's global period. For bilateral reporting, use modifier 50; CMS pays the bilateral procedure at 150%.

20939 billing questions
Can 20939 be reported by itself?
No. It is an add-on for marrow aspiration used in spinal grafting and must be reported with a qualifying primary spine procedure.
What documentation supports reporting 20939?
Document the marrow aspiration, its use for grafting, and the associated spinal procedure. Clarify separately performed bone harvesting when applicable.
How is bilateral reporting handled?
For a bilateral procedure, report modifier 50. CMS pays the bilateral service at 150%.
Is 20939 the code for harvesting bone graft?
No. It represents marrow aspiration for grafting; codes such as 20936, 20937, and 20938 describe different autologous bone graft services.
How does the global period affect 20939?
CMS pays it within the primary procedure's global period. Related postoperative care follows that primary procedure's global period.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
