However, its high costs and high utilization has prompted many insurance payors to require a prior authorization. This process remains burdensome and results in delays to patient care. The purpose of this study was to examine the relationship between several variables and the denial rate of outpatient MRI prior authorization requests from a single institution's department of orthopaedics.</p><p><strong>Methods: </strong>MRI prior authorization insurance data was retrospectively collected from January 2019 to December 2022. Patient demographics, imaging characteristics, and insurance details were extracted and stratified into generalized categories. Analysis of variance, multivariate logistic regression models, and odds ratios (ORs) were used to predict the likelihood of request denial with α = 0.05.</p><p><strong>Results: </strong>Of the 17,913 total MRI prior authorization requests identified, 885 (4.94%) were denied. Race and socioeconomic status were not markedly different between the authorized and denied cohorts; however, primary insurance payor, chief symptom, and anatomic location to be imaged were found to have notable differences between authorized and denied cohorts ( P < 0.0001). MRIs of the spine were less likely to be authorized compared with the shoulder (OR 0.51), upper extremity (OR 0.43), knee (OR 0.38), lower extremity (OR 0.34), and foot and ankle (OR 0.75) with P < 0.02 for each.

Our results are consistent with the current literature that has reported higher rates of denials for MRI prior authorization requests of the spine. Although we were not able to quantify the effect of these denials on patient care, the overall time required to process these requests undoubtedly causes delays in patient care. despite no notable difference seen in socioeconomic status, Horizon NJ Health, a major provider of only Medicaid insurance plans at our institution, was associated with a higher likelihood of denial. This suggests that MRI prior authorization requests submitted for Medicaid patients are more likely to be denied and cause an inequitable delay in care due to this process.</p>","PeriodicalId":51098,"journal":{"name":"Journal of the American Academy of Orthopaedic Surgeons","volume":" ","pages":"e244-e252"},"PeriodicalIF":2.6,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11774193/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Policies such as the Hospital Readmissions Reduction Program have targeted overall readmission reduction, using value-based strategies to improve healthcare quality. However, the implications of SDOH on these outcomes are not yet understood. We hypothesized that the area deprivation index (ADI) as a surrogate for SDOH would markedly influence readmission rates and healthcare costs in the 90-day postprocedural period for THA and TKA.</p><p><strong>Methods: </strong>We used the 100% US fee-for-service Medicare claims data from 2019 to 2021. Patients were identified using diagnosis-related groups. Our primary outcomes included 90-day unplanned readmission after hospital discharge and cost of care, treated as \"high cost\" if > 1 standard deviation above the mean.

Appropriate diagnosis and management of these disorders is paramount once discovered before, during, or after the patient's surgical course. Bleeding disorders disrupt the body's ability to control bleeding, commonly through platelet function and blood clotting. Normally, the vessel contracts and retracts once disruption of blood vessels occurs, limiting blood loss. Blood platelets adhere to exposed collagen, aggregate at the site, and obstruct blood loss. Because platelet aggregates are temporary, blood clotting is needed to back up the platelet plug and provide a milieu for the healing process that completes the hemostatic events. Disorders that interfere with any of these events can result in hemorrhage, drainage, or rebleeding. Bleeding disorders are a group of conditions, either hereditary or acquired, marked by abnormal or excessive bleeding and/or bruising. The most effective methods for assessing coagulation disorders include a detailed history and a series of blood tests. Clinical examination findings are notable but may be less specific. If a surgical patient has a bleeding disorder discovered preoperatively, postoperatively, or intraoperatively, treatments exist with medications, surgical management, interventional radiology procedures, and replacement therapy.</p>","PeriodicalId":51098,"journal":{"name":"Journal of the American Academy of Orthopaedic Surgeons","volume":" ","pages":"168-177"},"PeriodicalIF":2.6,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11774194/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142395042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
