Anyone billing for incubation of crossmatch? If so, are you billing it in addition to the AHG crossmatch? I am trying to benchmark billing of incubation of crossmatch (cpt code 86921).

All it says we do is an IS compatibility 86920   and AHG compatibility 86922

I was just wondering about this same thing today.

For example, if you do a gel crossmatch, you result an immediate spin and an AHG and drop CPT 86920 and 86922.

If you do a LISS crossmatch, you result immediate spin, 37C, and AHG results; so, should you drop CPT 86920, 86921, and 86922?

If not, why does 86921 exist?

As referenced by 'goodchild', if we do a LISS crossmatch, say for an autoantibody patient where the auto is not demonstrating in LISS, we charge for all 3 phases (IS, 37C and AHG). 

Otherwise our primary method for an AHG crossmatch is Gel so we charge an immediate spin crossmatch and an AHG crossmatch.  Same would hold true for a PeG crossmatch.

For a LISS crossmatch, we bill for the incubation of crossmatch.  We also bill for the AHG charge. 

For a gel crossmatch, we bill the immediate spin and the AHG. 

 

We bill for immediate spin, the 37C incubation and AHG phases.

IS xm 86920, 37 86921 ahg 86922

We don't do IS XM on gel XM because our computer is set up to detect ABO incompatibility.  However, if the computer is down, our procedure states that an IS needs to performed as well.  Maybe I will put the charge in for that.

If we do a Peg crossmatch should we bill for 37 also? We are checking for hemolysis at 37 and recording negative if no hemolysis is present. We are currently billing for IS and AHG only.
