CPT® Code 27090

The procedure described by CPT® Code 27090 refers to the surgical removal of a hip prosthesis, which is classified as a separate procedure. This operation is typically indicated when there are complications or failures associated with a previously implanted hip prosthesis. The surgical approach involves making an incision along the lateral aspect of the hip, following the line of the previous incision. Surgeons must carefully dissect through the soft tissue to access the hip prosthesis, which may be encased in scar tissue due to prior surgeries. In some cases, extensive soft tissue release may be necessary, which could involve partial release of the psoas tendon, gluteus maximus insertion, or the head of the rectus femoris muscle. The hip joint is then dislocated to expose the femoral head or the femoral head prosthesis for removal. The procedure requires meticulous attention to detail to ensure that all components of the prosthesis are removed without damaging surrounding structures. This code is specifically used for uncomplicated removals, distinguishing it from more complex cases that may require additional interventions, such as the removal of bone cement or the placement of a spacer in cases of infection.
