Q:  A patient with a previous hemiarthroplasty (say, right hip) comes in for a THR.  Do you code the removal and replacement of the device (head/stem) and just replacement of the liner/cup? 

A:  When a patient presents to upgrade a right hemiarthroplasty to a total hip replacement (THR) implant, the procedure is reported with the following codes:

  • 0SR90JZ, Replacement of Right Hip Joint with Synthetic Substitute, Open Approach
  • 0SPR0JZ, Removal of Synthetic Substitute from Right Hip Joint, Femoral Surface, Open Approach

The body part for the THR is right hip since both joint surfaces were replaced.  The body part for removal of the hemiarthroplasty implant is femoral surface of the hip.

Q:  How do you code polyethylene exchange of the left total knee. They took out the old one and placed a new one.

A:  Exchange of a tibial liner of the left knee is reported with two codes: one for removal of the old liner and one for the placement of the new liner. Placement of a new liner is reported with the root operation Supplement, so the codes for exchanging a left knee liner are:

  • 0SUD09Z, Supplement Left Knee Joint with Liner, Open Approach
  • 0SPD09Z, Removal of Liner from Left Knee Joint, Open Approach
