Commonly required documentation

• Clinical notes
• imaging showing the implant problem
• cobalt/chromium levels for metal-on-metal implants
• serologic testing for prosthetic joint infection where pain/loosening is the indication. Documentation supporting medical necessity and a clearly stated plan of care should be submitted at the time of the request and must include the following components: Clinical notes describing symptom duration and severity, specific functional limitations related to symptoms, and type and duration of all therapeutic measures provided. If conservative management is not appropriate, the reason must be clearly documented. Conservative management must include a combination of strategies to reduce inflammation, alleviate pain, and correct underlying dysfunction, including physical therapy AND at least ONE complementary conservative treatment strategy (physical therapy rendered by a qualified provider, or a supervised home treatment program with initial active instruction by MD/DO/PT and documented compliance
• complementary = anti-inflammatory medications and analgesics, adjunctive medications, intra-articular corticosteroid injection(s), or activity modification / trial period of rest). Failure of conservative management requires ALL the following: Patient has completed a full course of conservative management (as defined above) for the current episode of care
• Worsening of or no significant improvement in signs and/or symptoms upon clinical reevaluation
• More invasive forms of therapy are being considered. Reporting symptom severity - significant pain and functional impairment refer to pain rated at least 3 out of 10 in intensity and associated with inability to perform ADLs and/or IADLs. Imaging reports obtained within the past 12 months describing the degree of cartilage damage: X-ray report or provider interpretation of x-rays that utilizes or can be correlated with the Kellgren-Lawrence grading system of osteoarthritis, and/or MRI report from a radiologist that utilizes or can be correlated with the modified Outerbridge or similar classification system. General Recommendations (strongly recommended, not required): tobacco/nicotine abstinence for at least 6 weeks prior to surgery
