MOBIUSI INCThis dataset presents chronological high-deductible health plan rules, prior claims, and current claim scenarios, covering deductibles, coinsurance, copays, and annual out-of-pocket maximums. Each example combines plan rules and accumulated amounts to derive the deductible applied to the current claim, the patient's cost share, and the out-of-pocket limit status, with reasoning steps and a final answer. It supports health insurance claims analysis, benefit calculations, and the training and evaluation of reasoning-focused language models.
