🚨 Proud husband alert!

Perioperative management in sarcoidosis isn’t one-size-fits-all. We break down practical risk stratification and anesthetic considerations across airway, pulmonary, and cardiac involvement plus what to do before, during, and after surgery. @SPAQIedu @SOCCA_CritCare @ASALifeline @BJOAonline journals.lww.com/anesthesiology…

Congratulations Dr. Insler!

@InslerMD @ASALifeline @YAnesthesiology @RobertGaiser1 @Lisa_Leffert @HofkampMichael Congratulations! Very very well deserved

Receiving the @ASALifeline Resident Distinction Award as a CA-1 is a testament to the truly formidable mentorship I have received since matching at Yale. This award belongs as much to @YAnesthesiology @RobertGaiser1 @Lisa_Leffert @GuzziMD @HofkampMichael as it does to me.

As Shay Taylor finishes her doctoral studies at Howard University in Washington, D.C., she's working as a sub-intern at Yale-New Haven Hospital -- the same hospital where she worked as a janitor nearly a decade ago. wtnh.com/news/connectic…

Anthem’s plan to penalize hospitals for working with out-of-network physicians is indefensible. Physicians are exercising right established under the No Surprises Act, not violating them. This undermines patient access and physician autonomy. Shameful. @ASALifeline @ASAGrassroots

Wow… just wow. When you thought insurers couldn’t get more evil they come up with something even worse than you anticipated. So here we have an insurer that now plans to hurt hospitals who have physicians that aren’t contracted with the insurance carrier. This has so many issues.. 1) Hospitals can’t possibly figure out who is in- and out-of-network with the insurance carrier. It’s frankly not their job and it isn’t practical. 2) Physicians are going out of network due to decades of reductions in payments by both government and private payers. Anthem wants the ability to lower payments to physicians without pushback or consequence. What this leads to is every physician vertically integrating with hospitals which actually increases the costs to employers, patients, and Anthem. 3) We already have a shortage of certain specialties, in particular anesthesia. If this policy were to go through, we would see further difficulty getting surgeries for patients. Hospitalists would also likely be harder to find as many are out of network. ER physicians are too, but they are exempted in these cases 4) This will be particularly devastating to rural facilities who struggle to get coverage and in many cases are covered by locums tenens physicians who are frequently out of network 5) It’s not as easy to say “I am in network with Anthem”. There are probably 10’s of plans that Anthem administers in any given market and some of those plans are narrow networks, which means they limit the number of physicians on those networks intentionally. This means that there are physicians who are out of network by design of the insurer. Yet they will penalize the hospital for providing services to a patient whose doctor was out of network based on the decision of the insurer. This is terrible policy and bad for everyone but the insurance company. Patients and physicians must stand together to voice our concerns.

Anthem appears to have announced that it will penalize hospitals & assess of a penalty of -10% on facility reimbursements where the hospital based physicians are out of network (OON), as of 1/1/26. Credit to Ron Howrigon and his post on LinkedIn this morning (see below). The concept that physicians exercising rights granted to them by Congress under the federal No Surprises Act (NSA) and potentially under state laws can serve as a basis for Anthem penalizing the facilities is one that the law cannot abide IMHO. If true and I have no reason to believe otherwise, Anthem’s actions may be federal anti-trust violations, violations of unfair and deceptive trade practices, RICO claims and I am sure that the Rs on the Ways and Means committee would be most interested in questioning Anthem. For the state specialty societies in the states cited, and the national specialty societies, this announcement should be prioritized for possible future action. @ACEPNation @ASALifeline @RadiologyACR @AmerMedicalAssn @texmed @CMAdocs @EDPMA @RBMAConnect @MGMA_official linkedin.com/feed/update/ur…

@NadeenHussainMD @YaleDigestive Zach and I are so proud of you!

it’s been a whirlwind summer… graduated GI fellowship with a 3 week old! so grateful for my training @YaleDigestive

ASA is fighting a NY bill that, if enacted, would allow insurers to arbitrarily limit coverage and payment for #anesthesia services. NY @GovKathyHochul called a previous effort to cap anesthesia time "outrageous." Learn more from ASA President @dearnoldmd: ow.ly/FBQc50W0gY3

@SShergill_MD @NadeenHussainMD Thank you Sukhman!

@NadeenHussainMD @GuzziMD Congratulations Guzzi!

congrats to the YSM graduates, and also to @GuzziMD who was awarded the Francis Gilman Blake Award by the graduating medical students for being the most outstanding teacher of the medical sciences. So proud of you! Can’t believe we graduated med school this exact day 6 years ago
