Article Abstract
Study Design: Retrospective cohort study.
Objectives: This study assessed the effectiveness of a popular large language model, ChatGPT-4, in predicting Current Procedural Terminology (CPT) codes from surgical operative notes. By employing a combination of prompt engineering, natural language processing (NLP), and machine learning techniques on standard operative notes, the study sought to enhance billing efficiency, optimize revenue collection, and reduce coding errors.
Methods: The model was given 3 different types of prompts for 50 surgical operative notes from 2 spine surgeons. The first trial was simply asking the model to generate CPT codes for a given OP note. The second trial included 3 OP notes and associated CPT codes to, and the third trial included a list of every possible CPT code in the dataset to prime the model. CPT codes generated by the model were compared to those generated by the billing department. Model evaluation was performed in the form of calculating the area under the ROC (AUROC), and area under precision-recall curves (AUPRC).
Results: The trial that involved priming ChatGPT with a list of every possible CPT code performed the best, with an AUROC of .87 and an AUPRC of .67, and an AUROC of .81 and AUPRC of .76 when examining only the most common CPT codes.
Conclusions: ChatGPT-4 can aid in automating CPT billing from orthopedic surgery operative notes, driving down healthcare expenditures and enhancing billing code precision as the model evolves and fine-tuning becomes available.

Patients on Losartan Have Similar Rates of Manipulation Under Anesthesia After Total Knee Arthroplasty.

Introduction Patients have identified knee stiffness as a factor contributing to postoperative dissatisfaction after total knee arthroplasty (TKA). Losartan is an angiotensin receptor blocker (ARB) that has demonstrated antifibrotic effects; however, the impact of perioperative losartan on arthrofibrosis after TKA is not well understood. Therefore, the purpose of this study was to determine if losartan exhibits antifibrotic benefits in patients who undergo TKA by decreasing the rates of manipulation under anesthesia (MUA), when compared to patients who are not taking losartan.

Objective: To assess the ability of large language models (LLMs) to accurately simplify lumbar spine magnetic resonance imaging (MRI) reports.
Materials And Methods: Patients who underwent lumbar decompression and/or fusion surgery in 2022 at one tertiary academic medical center were queried using appropriate CPT codes. We then identified all patients with a preoperative ICD diagnosis of lumbar spondylolisthesis and extracted the latest preoperative spine MRI radiology report text.

Tremendous advances in ultrasound equipment and knowledge have expanded possibilities for the first trimester detailed ultrasound examination. Recommendations from national organizations to offer this service to patients with indications, coupled with recent modifications for dual use of the current procedural terminology code 76811 during pregnancy, will result in increased demand from patients and referring physicians. While proper reimbursement may motivate healthcare professionals to incorporate the first trimester detailed ultrasound examination into their practice and raise the standards of care in the first trimester, it can also be a challenging transition.

Purpose: This study aimed to evaluate how major US health care policy changes have influenced long-term Medicare reimbursement trends for upper-extremity flap and microvascular procedures from 2002 to 2023.
Methods: Reimbursement data for 28 common flap and microvascular procedures were extracted from the Medicare Physician Fee Schedule database using Current Procedural Terminology codes. Adjustments for inflation were made using the Consumer Price Index.
