In Molly C. v. Oxford Health Insurance, Judge Moses denied Oxford’s motion to exclude expert testimony used to support class certification.
The ruling affects Oxford Health Insurance, Inc., plaintiffs Molly C. and Naomi L., and the proposed groups of Oxford members with eating disorders. It allows plaintiffs to rely on Dr. Frank Fox’s opinions in seeking class certification but does not decide whether the classes will be certified.
What happened
Molly C. v. Oxford Health Insurance, Inc. involves claims that Oxford violated the federal mental-health-parity law by denying coverage for nutritional counseling for eating disorders while covering similar counseling for diabetes. Molly C. and Naomi L. asked the court to certify groups of affected Oxford members.
Oxford asked the court to exclude the opinions of plaintiffs’ expert, Dr. Frank Fox, who estimated the number of people in the proposed groups. Oxford argued that his analysis was irrelevant or unreliable. The court found that his opinions could help evaluate whether the proposed groups were large enough for class certification and that Oxford’s criticisms generally concerned the weight of his evidence, not whether it could be considered.
Judge Moses denied Oxford’s motion to exclude Dr. Fox’s opinions. She emphasized that this ruling did not decide whether the proposed groups satisfy the requirements for class certification; that decision remains for District Judge Paul G. Gardephe.

Background
Molly C. and Naomi L. are beneficiaries of group health insurance plans administered by Oxford Health Insurance, Inc. They received outpatient nutritional counseling for eating disorders and submitted claims that Oxford denied because the plans did not cover those services. The plaintiffs allege that Oxford violated the Mental Health Parity and Addiction Equity Act because the plans covered nutritional counseling for physical conditions such as diabetes.
The plaintiffs sought certification of two proposed subclasses: a Denied Claims Subclass for members whose claims were denied as not covered, and a No Claims Subclass for members who received the counseling but did not submit claims. Their class-certification motion remains pending before District Judge Paul G. Gardephe.
Expert Evidence and the Motion
To support the required showing that the proposed subclasses were large enough for class treatment, the plaintiffs relied on declarations from Dr. Frank Fox, a consulting economist. Using Oxford claims data and published studies, Dr. Fox estimated that at least 458 Oxford members submitted 1,461 claims for outpatient nutritional counseling for eating disorders that were denied as not covered. He also estimated that hundreds of additional members may have received the counseling without submitting claims.
Oxford moved to exclude Dr. Fox’s opinions under Federal Rule of Evidence 702 and the standards for evaluating expert testimony. Oxford argued that his analysis of the denied claims involved only simple arithmetic and did not require an expert. It also argued that his estimates concerning the No Claims Subclass were irrelevant and unreliable because they relied on assumptions and studies that were incomplete, old, or not specifically tied to Oxford’s New York members.
Court’s Analysis
Judge Moses concluded that Dr. Fox’s opinions were relevant because they tended to show whether at least 40 members received nutritional counseling but did not submit claims. His estimates were not required to establish numerosity by themselves, but they supplied a necessary part of the analysis. The court also found that reviewing and organizing a lengthy claims dataset, deciding which claims to count, and presenting the results in an understandable format were appropriate subjects for expert testimony.
The court rejected Oxford’s argument that the declarations failed to qualify as expert reports. Rule 26 does not impose a minimum page length, and the court found that Dr. Fox’s declarations provided his opinions, the supporting facts and data, his qualifications, and other required information.
The court further held that Oxford’s objections to Dr. Fox’s data and assumptions generally concerned the weight or persuasiveness of his opinions rather than their admissibility. Oxford had not shown that Dr. Fox lacked sufficient data or relied on information that experts in his field could not reasonably use. At the class-certification stage, the judge acts as both the evaluator of expert admissibility and the factfinder, so there was no risk that a jury would be confused by potentially imperfect testimony. The court therefore resolved doubts in favor of allowing the evidence to be considered.
Disposition
Judge Barbara Moses denied Oxford’s motion to exclude Dr. Fox’s opinions. The ruling only permits the court to use that testimony when deciding whether the proposed subclasses satisfy the requirements for class certification. It does not decide whether those requirements are met, and the numerosity decision remains for District Judge Paul G. Gardephe.
