How far do we take collateral estoppel?

By Jason Tenenbaum 8 min read

Key Takeaway

A New York appellate court examines when collateral estoppel applies in no-fault insurance disputes, highlighting the importance of what issues were actually litigated and decided.

Understanding Collateral Estoppel in No-Fault Insurance Cases

Collateral estoppel is a legal doctrine that prevents parties from relitigating issues that have already been decided in previous cases. In New York’s no-fault insurance system, this principle often comes into play when healthcare providers and insurance companies find themselves in multiple disputes over the same underlying claims. However, as a recent appellate decision demonstrates, the application of collateral estoppel isn’t always straightforward.

The doctrine only applies when an issue was “fully litigated and decided” in a prior case. This requirement becomes particularly important in complex no-fault disputes where multiple legal and factual issues may be at stake. Understanding when collateral estoppel applies—and when it doesn’t—is crucial for both providers and insurers navigating the no-fault system.

Jason Tenenbaum’s Analysis:

Palisade Surgery Ctr. LLC v Allstate Prop. & Cas. Ins. Co., 2016 NY Slip Op 51824(U)(App. Term 1st Dept. 2016)

“The issue of medical necessity was not fully litigated or decided in the prior first-party no-fault action, and thus the doctrine of collateral estoppel does not bar defendant-insurer from raising the medical necessity defense in this action (see Kaufman v Eli Lilly & Co., 65 NY2d 449 ; cf. Buechel v Bain, 97 NY2d 295, 303-304 , cert denied 535 US 1096 )”

I am left to believe that some provider prevailed somewhere. Perhaps the issue of medical necessity was never reached? I cannot make out what happened here, but I am curious what procedurally occurred to cause the provider to take an appeal on this one in a court where you are out at least $1500 for a reproduced record and brief.

Key Takeaway

This case illustrates that collateral estoppel only prevents relitigation of issues that were actually decided in previous cases. Even if a provider won a prior lawsuit, insurers may still raise defenses like medical necessity in subsequent actions if those specific issues weren’t fully addressed before. The high cost of appeals suggests significant stakes were involved, likely related to broader no-fault insurance litigation strategies.

It’s my case. This case is the facility fee and anesthesia for MUA in NJ. There was another case to collect for the two co-surgeons. I won summary judgment for the two co-surgeons in another action. The Defendant opposed on the basis of medical necessity but never put in the peer review. Mainly, they argued that the denial was sufficient to establish the defense. Thereafter, they renewed/reargued and still lost. They also appealed and still lost. As a result, I moved for SJ in the facility and anesthesia case. They argued that the issue of medical necessity had not been fully litigated (even though they didnt establish that they didnt have a “full and fair opportunity” to present the peer). They also argued that the medical necessity of the facility is legally separate from the facility and anesthesia. I also argued that medical necessity for the facility is separate and distinct from the MUA. Anyone who wants to avoid collateral estoppel can use this case and point to additional records to show that it wasnt FULLY litigated.
