Revision of Dislocated Bipolar Hip Arthroplasty


Best answers
Need help with coding:

Patient had a previous bipolar hip hemiarthroplasty for femoral neck fx. Patient now presents dislocated - Dr. performs a revision: greather trochanter displaced along with dislocation of hip. Appeared that the hip was unstable primarily because of the avulsed greater trochanter & lack of soft tissue integrity. Hip was dislocated - the ball was knocked off of the trunnion & a Charnley was used & retractors placed around the native acetabulum - then reamed - then Biomet cup was impacted. Then screws were implanted for additional fixation. Then selected a 36 mm head w/3mm neck Freedom contrained liner which was then impacted & a 36 mm head was placed on the trummion & reduced and hip then stable.

Patient still in global - what CPT code would be used for this - would it be 27137?

Any and all help is greatly appreciated!!!:) :)
