The Issue
Medical-billing disputes can involve coding, clinical documentation, charge development, payment methodology, medical necessity, benchmark construction, payer policy, and healthcare economics. These fields overlap, but they are not interchangeable. A polished witness may have real experience in one area while presenting broader opinions that a jury or other non-specialist cannot readily separate.
Why it matters
- Precise dollar figures, codes, and percentiles can create an impression of authority without revealing the analytical path.
- General credentials do not establish qualification for every opinion category.
- Cross-examination works better when sources, calculations, assumptions, and limits are disclosed before testimony.
Policy Direction
Recommended action: Adopt a content-neutral Billing Opinion Disclosure Standard that requires a retained expert to identify each opinion, demonstrate qualification for that opinion, disclose the sources and benchmark provenance, explain the method and calculations, connect the analysis to the case, and state material assumptions and limitations.
- Classify each opinion: coding, clinical, charge, payment, benchmark, medical-necessity, or economic.
- Require qualification-to-opinion fit for each category—not merely a broad résumé or occupational title.
- Disclose records, benchmark provenance, method, calculations, assumptions, exclusions, case linkage, and relevant relationships.
- Apply the standard symmetrically and use cure or supplementation before disproportionate sanctions.
What the research contributes
BORS100 is a published seven-domain framework for examining whether the disclosed foundation of a billing or medicolegal opinion is visible, reproducible, case-specific, and auditable. It can organize review, report writing, and comparison without replacing the governing legal standard.
Evidentiary Boundary
BORS100 is a proposed, pilot-use structured review aid. It does not independently determine truth, admissibility, credibility, payment, bad faith, or whether an expert is qualified under controlling law. A high score does not prove correctness; a low score does not prove misconduct.
Require the expert to define the opinion, show the method, and disclose the limits before asking a decision-maker to rely on the conclusion.
