“The Day-Filled Rule”: Eleventh Circuit Clarifies How Insurers Must Calculate Oral-Chemotherapy Benefits

1. Introduction

Henry R. Seawell III and Kathryn D. Seawell sued Colonial Life & Accident Insurance Company for allegedly short-paying benefits under a supplemental cancer policy purchased in 2002. After Kathryn’s 2016 metastatic breast-cancer diagnosis, she began taking the oral chemotherapy drug Ibrance, filled roughly every 28 days. Although the retail cost of a monthly supply exceeds USD 10,000, the Seawells’ major-medical insurer reduced their out-of-pocket exposure to roughly USD 10 per fill. Each time Kathryn filled the prescription, Colonial paid USD 400 – the “daily” cap stated in the policy – but never more than USD 1,200 per month (the “monthly” cap).

The Seawells contended that the policy required Colonial to treat every dose within a multi-day prescription as a separate “day” for benefit purposes, which would trigger the USD 1,200 monthly maximum every month. The district court disagreed and granted summary judgment to Colonial. On appeal, the Eleventh Circuit affirmed, announcing a clear interpretive principle for similar policy language: benefits for “the cost of the prescription for the day you have the prescription filled” are triggered only on the day of dispensing, not each day the medicine is consumed.

2. Summary of the Judgment

Holding: The phrase “cost of the prescription for the day you have the prescription filled” unambiguously ties the benefit to the single calendar day on which the pharmacy dispenses the medication; therefore Colonial’s practice of reimbursing USD 400 per fill – subject to a USD 1,200 monthly ceiling – fully complied with the policy.
Outcome: District court’s grant of summary judgment in favor of Colonial Life & Accident Insurance Company affirmed.
Governing Law: Alabama contract-interpretation principles applied under diversity jurisdiction.
Procedural Note: Plaintiffs’ contemporaneous motion for class certification became moot after the merits ruling; that issue was not appealed.

3. Analysis

3.1 Precedents Cited and Their Influence

Dyer v. Lee, 488 F.3d 876 (11th Cir. 2007) – reiterated the summary-judgment lens: facts viewed in favor of the non-movant.
Hurlbert v. St. Mary’s Health Care Sys., Inc., 439 F.3d 1286 (11th Cir. 2006) – another articulation of the Rule 56 standard.
State Farm Mut. Auto. Ins. Co. v. Spangler, 64 F.4th 1173 (11th Cir. 2023) – distinguished interpretation of an insurance contract as a “pure question of law.”
Snell v. United Specialty Ins. Co., 102 F.4th 1208 (11th Cir. 2024) – restated Alabama’s rule that insurance contracts are interpreted like any other contract.
Robinson v. Liberty Mut. Ins. Co., 958 F.3d 1137 (11th Cir. 2020) – duty to enforce unambiguous policy language.
Safeway Ins. Co. of Ala. v. Herrera, 912 So. 2d 1140 (Ala. 2005) – definition of ambiguity: reasonably susceptible to two or more constructions.
Jay v. USAA, 343 So.3d 18 (Ala. 2021) – warning against “strained or twisted reasoning.”
Nielsen v. Preap, 586 U.S. 392 (2019) & Niz-Chavez v. Garland, 593 U.S. 155 (2021) – Supreme Court grammar canons illustrating the significance of the article “the” and the concept of a “discrete moment” for statutory interpretation; imported by analogy to contractual text.

The Eleventh Circuit employed these authorities cumulatively to (1) confirm the de-novo standard of review, (2) apply Alabama’s plain-meaning rule, and (3) cabin use of contra proferentem to situations of genuine ambiguity. The Supreme Court grammatical decisions added interpretive heft, underscoring that “the day” indicates a single, definite day.

3.2 Legal Reasoning

Plain-Language Focus. The court began with the “ordinary meaning” canon, consulting contemporary dictionaries. “Prescription,” in common usage, denotes the written order itself – not each individual pill or dose.
Holistic Reading. Rather than isolating a single noun, the court read the entire clause, highlighting the definite article “the” and the verb phrase “have the prescription filled,” which describes the pharmacy’s dispensing event. This context foreclosed plaintiffs’ alternative interpretation.
Structural Confirmation. The presence of both a USD 400 daily cap and a USD 1,200 monthly cap, the panel observed, reveals an internal architecture directed at limiting payouts where multiple fills (e.g., partial fills) occur in one month, not at multiplying benefits by dose count.
Application of Alabama Ambiguity Doctrine. Because the clause was not “reasonably susceptible” to the plaintiffs’ construction, the contra proferentem doctrine never came into play.
Rebuttal of Plaintiffs’ Extratextual Arguments. Definitions from AI tools and re-purposed dictionary snippets were discarded as “strained or twisted reasoning.” Fictional ambiguities cannot be manufactured by creative linguistics.

3.3 Impact on Future Litigation and Insurance Practice

The decision announces what practitioners will likely dub the “Day-Filled Rule” for supplemental cancer policies and any policy provisions keyed to “the prescription for the day [it is] filled.” Key consequences include:

Contract Drafting: Insurers may now rely on this language without fear of exposure to multi-dose claims within the Eleventh Circuit so long as similar caps exist. Drafting lawyers might nonetheless tighten wording further (e.g., “per pharmacy dispensing event”) to inoculate against arguments in other jurisdictions.
Claims Handling: Adjusters can confidently limit oral-chemotherapy benefits to the dispensing date, streamlining internal guidelines and reducing litigation risk.
Class Action Strategy: Plaintiffs’ bar faces a higher hurdle crafting nationwide classes based on identical language; the district court’s denial of certification, though un-appealed, hints at manageability and predominance problems if the merits fail.
Broader Contract Law: The opinion reinforces that courts will import modern linguistic-based tools (Supreme Court “grammar canons”) into ordinary contract interpretation, not just statutory contexts.

4. Complex Concepts Simplified

Supplemental Cancer Policy: A standalone insurance product that pays fixed, often modest, benefits to offset incidental expenses of cancer treatment (e.g., travel, lost wages). It “supplements” – not replaces – major medical coverage.
Oral Chemotherapy Benefit: A flat-dollar or capped reimbursement specifically for cancer drugs taken by mouth, differentiated from intravenous chemotherapy or radiation benefits.
Summary Judgment: A procedural device where the court decides a case without trial because no material fact is genuinely disputed and one party is entitled to judgement as a matter of law.
Contra Proferentem (aka “against the drafter” rule): If an insurance clause is ambiguous, courts construe it against the insurer who drafted it. However, the rule never triggers if the text is clear.
Diversity Jurisdiction: Federal jurisdiction based on parties being citizens of different states and the claim exceeding USD 75,000; federal court then applies state substantive law (here, Alabama).

5. Conclusion

In Seawell v. Colonial Life, the Eleventh Circuit delivered a textbook application of contractual plain-meaning interpretation to insurance disputes, crystallizing the “Day-Filled Rule” for oral-chemotherapy benefits. The court’s methodical reliance on grammar, dictionary definitions, and policy structure underscores that creative “per-dose” theories cannot override clear drafting. For insurers, the case validates current benefit-calculation practices; for practitioners, it provides a citation-ready template for defeating similar ambiguity arguments. Above all, the decision affirms that sympathy for a claimant’s medical plight does not license courts to rewrite unambiguous contracts – a principle that resonates well beyond the cancer-policy niche.
