Medicare Reimbursement Trends for Interventional Radiology Procedures: 2012 to 2020

PurposeTo investigate the reimbursement trends for interventional radiology (IR) procedures from 2012 to 2020.Materials and MethodsReimbursement data from the Physician Fee Schedule look-up tool from the Centers for Medicare and Medicaid Services was compiled for 20 common IR procedures. The authors then investigated compensation trends after adjusting for inflation and from the unadjusted data between 2012 and 2020.ResultsFrom 2012 to 2020, the mean unadjusted reimbursement for procedures decreased by ?6.9% (95% confidence interval [CI], ?13.5% to ?0.34%). This trend was even more profound after inflation was taken into account, with a mean decline in adjusted reimbursement of ?18.7% (95% CI, ?24.4% to ?12.9%) during the study period, with a mean yearly decline of ?2.8%. The difference between the mean unadjusted and adjusted payment amounts was significant (P = .012). Similarly, linear regression analysis of the adjusted average reimbursement across all procedures revealed an overall decline from 2012 to 2020 (R² = 0.97), indicating a steady decline in reimbursement over time.ConclusionsIn just under a decade, IR has experienced significant reimbursement cuts by Medicare, as demonstrated by both the unadjusted and inflation-adjusted payment trends. Knowledge of these trends is critically important for practicing interventional radiologists, leaders within the field, and legislators, who may play a role in formulating future reimbursement schedules for IR. These data may be used to help support more amenable reimbursement plans to sustain and facilitate the growth of the specialty.

Association between first oral examination characteristics and dental treatment needs in privately insured children: A claims data analysis

BackgroundEarly childhood caries (ECC) remains the most common, preventable infectious disease among children in the United States. Screening is recommended after the eruption of the first tooth, but it is unclear how the age at first dental examination is associated with eventual restorative treatment needs. The authors of this study sought to determine how provider type and age at first dental examination are associated longitudinally with caries experience among children in the United States.MethodsDeidentified claims data were included for 706,636 privately insured children aged 0 through 6 years as part of the nationwide IBM Watson Health Market Scan (2012-2017). The authors used Kaplan-Meier survival analysis to describe the association between the age of first visit and restorative treatment needs.ResultsA total of 21% of this population required restorative treatment, and the average age at first dental examination was 3.6 years. A multivariable Cox proportional hazards model showed increased hazard for restorative treatment with age at first dental visit at 3 years (hazard ratio, 2.05; 95% CI, 1.97 to 2.13) and 4 years (hazard ratio, 3.99; 95% CI, 3.84 to 4.16).ConclusionThe high proportion of children requiring restorative treatment and late age at first dental screening show needed investments in educating general dentists, medical students, and pediatricians about oral health guidelines for pediatric patients.Practical ImplicationsCommunicating the importance of children establishing a dental home by age 1 year to parents and health care professionals may help reduce disease burden in children younger than 6 years.

A lethal and rare cause of arthrogryposis: Glyt1 encephalopathy

Glycine encephalopathy with normal serum glycine (MIM #617301), also known as GLYT1 encephalopathy, is an extremely rare disorder caused by biallelic variants in SLC6A9 and characterised by facial dysmorphic features, skeletal findings including contractures, knee hyperextension, and joint dislocations and seizures. To date, only ten patients from five families have been reported and only two of them could survive until childhood. In this study, we report on a consanguineous Turkish couple with a history of six pregnancies with three habitual abortions and three postpartum exitus. While in three pregnancies the babies were born prematurely at 32nd gestational week by emergency ceserean section due to hydrops and fetal distress, the other pregnancy was medically terminated at 16th gestational week due to absent fetal heart activity. The product of all these three pregnancies exhibited similar phenotype including short neck, thoracic kyphosis, hypertrichosis, joint contractures and dislocations, hypertonia, knee hyperextension and facial dysmorphic features. Trio exome sequencing was performed prenatally during the last pregnancy and a novel VUS variant in SLC6A9 and a likely pathogenic variant in MTOR gene were detected. DNA isolation was performed from frozen muscle and adrenal tissue of previously autopsied fetuses with similar clinical features, and the same variants were confirmed in both of them. Our data suggest that SLC6A9 and MTOR variants may be responsible for this extremely lethal phenotype in this family.
