1-15-19: Pt. underwent right total hip replacement.
2-21-19: Taken back to OR with "draining seroma." Dr. exchanged right total hip femoral ball and polyethylene liner and performed extensive lavage of wound with insertion of antibiotic beads.

Do I bill 27030 or 26990 ? Would DX be M96.840, Z96.641 ??

I’ve spent all day on this and have even entertained 27134 – 78, 52

Can anyone help? I feel ridiculously stupid !!!!!

THANKS!!!!!
