Results: The work RVU component decreased in 18 of 23 (78.
Purpose: To study trends in volume and reimbursement for paracentesis and thoracentesis by physicians and advanced practice providers (APPs) after the introduction of discreet Current Procedural Terminology codes for image guidance.
Methods: Medicare claims for 2012 to 2018 (paracentesis) and 2013 to 2018 (thoracentesis) were extracted using Current Procedural Terminology codes for blind and image-guided paracentesis and thoracentesis. Total volumes were analyzed by provider specialty.
Purpose: The purpose of this study is to analyze trends in Medicare volume and reimbursement for percutaneous and surgical ablation as well as laparoscopic and open partial nephrectomy for treatment of small renal tumors from 2010 to 2018.
Methods: Claims from the Medicare Part B Physician/Supplier Procedure Summary from 2010 to 2018 were extracted using CPT codes for percutaneous and surgical renal ablation and surgical and laparoscopic partial nephrectomy. Facility reimbursement and relative value units (RVUs) were obtained using the Centers for Medicare & Medicaid Services physician fee schedule look-up tool.
Purpose: The purpose of this study is to analyze trends in Medicare volume and physician reimbursement for percutaneous ablation, surgical ablation, and resection of liver tumors from 2010 to 2018.
Methods: Claims from the Medicare Part B PSPSMF for the years 2010 to 2018 were extracted using the CPT codes for percutaneous and surgical ablation of liver tumors and surgical liver resection. Total procedural volume and physician payment were analyzed by procedure and physician specialty.
Purpose: To evaluate the safety and efficacy of percutaneous nephrostomy (PCN) in pregnancy.
Materials And Methods: PCN tubes were placed during 52 pregnancies in 49 patients from 2008 to 2018. The medical records during pregnancies were retrospectively reviewed for imaging findings, procedural parameters, outcomes of delivery, and complications.
The Michigan Appropriateness Guide for Intravenous Catheters (MAGIC) was published in 2015, recommending more restricted indications for peripherally inserted central catheter (PICC) placement, particularly for those placed by physicians. Changes in PICC placement volume since the publication of MAGIC is largely unknown. The purpose of this article was to study the trends in volume and reimbursement for PICC placement by physicians and advanced practice providers (APPs) for Medicare enrollees from 2010 to 2018 with specific attention to the changes in volume after the publication of MAGIC in 2015.

Claims from the Medicare Part B Physician/Supplier Procedure Summary Master File for the years 2010 through 2018 were extracted by use of the CPT codes for arteriovenous fistula and arteriovenous graft maintenance procedures. Total volumes, payment amounts (professional component), and trends were analyzed by physician specialty and practice setting.
View Article and Find Full Text PDFBackground Context: In 2010, the American Academy of Orthopedic Surgeons published guidelines strongly recommending against the use of vertebroplasty following the publication of randomized control trials that failed to show significant improvement in pain. Vertebroplasty has remained controversial since those findings.
Purpose: To study and provide an update on utilization of vertebroplasty and kyphoplasty procedures among Medicare beneficiaries by physician specialty and practice setting following publication of recommendations against vertebroplasty in 2010.
Objective: Although radiofrequency ablation is well validated for treatment of osteoid osteoma, newer technologies, namely cryoablation, have been less thoroughly studied. The purpose is to perform a systematic review and pooled analysis of percutaneous ablation technologies for treatment of osteoid osteoma with subset analysis of intra-articular and spinal tumors.
Material And Methods: A total of 36 of 79 identified manuscripts met inclusion criteria, comprising 1863 ablations in 1798 patients.
Objectives: In adults, elevated hepatic venous pressure gradients (HVPGs) are correlated with the degree of liver fibrosis on histopathology and predict worse outcomes including variceal bleeding and death. We aimed to examine the association between HVPG measurements, histopathologic findings, and clinical indicators of portal hypertension in children.
Methods: Utilizing retrospective data from 2 pediatric centers between 2006 and 2015, we identified children who underwent simultaneous HVPG measurement and transjugular liver biopsy.
Objective: The purpose of this study is to compare long-term clinical effectiveness before and after implementation of a structured protocol for percutaneous drainage of benign anastomotic biliary strictures.
Materials And Methods: Three hundred five adult patients undergoing percutaneous biliary drainage for biliary anastomotic strictures between 1994 and 2015 were identified using Current Procedural Terminology billing codes, with 234 undergoing intervention before implementation of a structured protocol and 71 undergoing intervention after implementation of the protocol. The frequency of surgical anastomotic revision was compared between patients treated before and after the implementation of the structured protocol.
Background: Despite the demonstrated feasibility of the single-stick technique in the femoral vein, its use in neonates and infants for placing central lines in internal and external jugular veins has not been reported.
Objective: Describe and assess the safety and efficacy of tunneled jugular central venous catheter placement performed under ultrasound (US) and fluoroscopic guidance in neonates and infants weighing <5 kg using the single-stick technique at three tertiary pediatric hospitals.
Materials And Methods: Thirty-three children weighing less than 5 kg received tunneled central venous access in either internal or external jugular veins using the single-stick technique.
Background: Despite a continuing emphasis on evaluation and management clinical services in adult interventional radiology (IR) practice, the peer-reviewed literature addressing these services - and their potential economic benefits - is lacking in pediatric IR practice.
Objective: To measure the effects of expanding evaluation and management (E&M) services through the establishment of a dedicated pediatric interventional radiology outpatient clinic and inpatient E&M reporting system.
Materials And Methods: We collected and analyzed E&M current procedural terminology (CPT) codes from all patients seen in a pediatric interventional radiology outpatient clinic between November 2014 and August 2015.
Objectives: The aim of the study was to describe and assess the technical success and safety of ultrasound-guided liver biopsy with gelatin sponge pledget tract embolization technique in infants <10 kg across 3 tertiary pediatric hospitals.
Materials And Methods: There were 67 pediatric patients weighing <10 kg (36 boys; 31 girls; average age 202 days; average weight 6 kg, range 1.5-9.
