Various regulations and practice patterns develop on the basis of Local Coverage Determination (LCD), which are variably perceived as guidelines and/or mandated polices/ regulations. LCDs developed in 2021 and effective since December 2021 mandated a minimum of 2 views for final needle placement with contrast injection which includes both anteroposterior (AP) and lateral or oblique view. Radiation safety has been a major concern for pain physicians and multiple tools have been developed to reduce radiation dose, along with improvement in technologies to limit radiation exposure while performing fluoroscopically guided interventional procedures, with implementation of principles of As Low As Reasonably Achievable (ALARA). The mandated 2 views of epidural injections have caused concern among some physicians, because of the potential of increased exposure to ionizing radiation, despite application of various principles to minimize radiation exposure. Others, including policymakers are of the opinion that it reduces potential abuse and improves safety. ⋯ The results of this study showed significant increases in radiation exposure time and dosage; however, increase of dosage was overall 21% median Interquartile Range (IQR) compared to 133% of radiation dose median IQR. In addition, the results also showed variations for procedure, overall showing highest increases for lumbar interlaminar epidural injections for time (43%) and caudal epidural injections for dosage (191%).

Evaluation of new and established patients is an integral part of interventional pain management. Over the last 3 decades, there has been significant confusion over the proper documentation for evaluation and management (E/M) services in general and for interventional pain management in particular. Interventional pain physicians have learned how to evaluate patients presenting with pain on the basis of their specialty training. ⋯ This is in contrast to prior guidelines wherein for new patients, all 3 elements with history, physical examination and MDM , and for established patients have been met. For ease of appreciation, an algorithmic approach created by the American Medical Association (AMA), and Centers for Medicare and Medicaid Services (CMS) approved a new MDM table outlining all of the appropriate criteria. This review systematically describes the changes and provides an algorithmic approach for application in interventional pain management practices.

The suprascapular nerve (SSN) is an important nerve that contributes to shoulder joint sensation and movement. The anterior suprascapular nerve block (aSSNB) has the potential for noninferior analgesic effect compared with the interscalene block while preserving respiratory function. This study investigated the median effective volume (MEV) of 0.375% ropivacaine in aSSNB for analgesic effect among patients undergoing arthroscopic shoulder surgery. ⋯ To produce effective analgesic effect, the MEV50 is 6 mL, and the MEV95 is 13.88 mL in patients undergoing arthroscopic shoulder surgery who receive an aSSNB using 0.375% ropivacaine for analgesia.
