I would need to see the op note or more information to help you. But...
A poly liner exchange and washout of the TSA (glenohumeral) for infection is 23040. It's not just 23030 because it requires an arthrotomy. 23030 is only incision and drainage deep but not into the joint.
You would go into the TSA revision codes 23473 or 23474 when either the humeral
or glenoid components, or both are removed and replaced in the same operative session.
11044 is not correct for poly liner exchange & washout of a prosthesis.
Also to your statement, "My physician is doing a revision of a reverse total shoulder arthroplasty (23473). He also did an excisional debridement of fascia, abscess cavity, bone, muscle, devitalized tissue from the infection." You would not report any of the debridement work, washout, etc. if he truly was doing 23473 because all of that would be included in 23473. 23473 includes arthrotomy, synovectomy, osteotomy and the removal of the components in place, among other things.
If we start talking about staged treatment of infection of a prosthesis in the hip/knee/shoulder, then we start getting into different codes and possible drug delivery device codes too.
I think I have suggested to you prior that the AAOS Complete Global Service Data for Ortho would really help you and/or possibly taking an AAOS/Zupko ortho course

I am pretty sure there are CPT Assistant articles that address this liner exchange question and other prosthesis questions. If you have a CPT Professional or Expert book under the codes it directs you to the month/year of the CPT Assistant.
