Method validation and environmental monitoring of triethanolamine ester quaternary ammonium compounds
In this study water and sediment samples, collected from the River Nene (Northamptonshire) at several sites in the vicinity of the Great Billing sewage treatment plant (STP), were analysed for triethanolamine quaternary compounds (TEAQ, ester quats). A method was developed using liquid chromatography tandem mass spectrometry (LC/MS/MS) with a electrospray ionisation source (ESI). Ten components were determined using a characterised commercial sample of Tallow TEAQ as a standard. To our knowledge this is the first time environmental concentrations of a wide spectrum of individual homologues of TEAQ have been reliably quanti...

Ask Congress to Support Complexity Add-on Code
Implementation of the G2211 add-on code for evaluation and management services is included in the CY 2024 Medicare Physician Fee Schedule, barring further delays. Ask your lawmakers to support timely implementation and patient access to complex care. (Source: The Rheumatologist)

We Want You: Your Role in the CPT Valuation Process
Accurate reimbursement for rheumatology services ensures rheumatologists can run successful practices and provide needed care, but only if they speak up through survey input to explain how much that care costs. Here’s how to participate in the process when rheumatology CPT codes come up for review. (Source: The Rheumatologist)

The Megaendoprosthesis in Revision Arthroplasty - a Cost-revenue Analysis in the aG-DRG System
Z Orthop Unfall. 2023 Oct 23. doi: 10.1055/a-2174-1439. Online ahead of print.ABSTRACTMegaendoprosthesis offer a viable treatment in complex revision arthroplasty cases with good functional outcome. In the context of a neoplastic indication, the diagnosis-related group (DRG) I95A is usually assigned with a relative weight of 4.906 (2021). In contrast, in revision arthroplasty, the appropriate DRG is assigned, depending on the joint replacement. The additional costs compared to the invoiced DRG are to be compensated by agreeing on hospital-specific individual fees. These complex revision arthroplasties set high technical an...
