Can someone help me with the coding of the following procedures:
1. Left total hip arthroplasty revision, conversion to constrained liner (I believe this is CPT 27134?)
2. Left hip debridement and irrigation, down to and including removal of bone (CPT 11044? Is this bundled with the main procedure?)
3. Open advancement of hip abductor tendons (CPT 27299 matched to 27098? Again, is this considered incidental to the primary procedure?)
