Cert Reviewer Error: 21 — Insufficient Documentation
Missing the following documentation: Pre-Operative History and Physical specifics as related to bilateral knees prior to surgery such as conservative treatment completed, injections, physical therapy; pain medications and pre-operative X-rays showing specific osteoarthritic changes such as joint space narrowing, osteophytes, sclerosis, etc., or bone-on-bone process.
