Machine-Readable Files and the Reality of Healthcare Litigation

Interpreting the Fine Print: Machine-Readable Files and the Reality of Healthcare Litigation

Wayne Bennett, DC, DABCC, DABCO

Machine-Readable Files (MRFs) rode in with the promise of transparency. What they have delivered—particularly for litigators—is a fast-growing stretch of unsettled ground at the intersection of healthcare contract law, data interpretation, and regulatory compliance. As enforcement actions and private litigation pick up pace, courts are coming to terms with a simple fact: MRF analysis is not self-explanatory, and the heavy lifting is increasingly being done by expert witnesses.

MRFs were not built for patients, providers, or judges. They were built for machines. The fact that people are now arguing over them in depositions and courtrooms explains a good deal of the confusion. Attorneys are encountering disputes involving improper reimbursement, parity violations, network misclassification, and contractual misconduct—each hinging on what an MRF actually says, what it really means, and whether it lines up with the deal that was struck.

From an evidentiary standpoint, this terrain feels familiar, but the footing is new. There is limited case law interpreting MRFs. There is no widely recognized credential for an “MRF analyst.” The available guidance is still taking shape and tends to move faster than formal consensus. And the real skill lies not just in reading the data, but in translating it into practical reality—and explaining it in a way that makes sense to people who did not plan on a science lesson in court. That makes Frye-style qualification—grounded in general acceptance within relevant professional and regulatory communities—a particularly good fit for early-stage MRF litigation.

Under Frye, the question is not whether MRF analysis is some new kind of frontier science. It is whether the methods used to extract, normalize, and interpret the data are the same ones relied upon by experienced professionals in healthcare reimbursement, compliance, and contract analysis. In many cases, courts benefit more from understanding how the industry actually works than from trying to shoehorn MRF testimony into a Daubert framework better suited to laboratory science than real-world regulatory analytics.

MRF expert consultation is becoming central across several recurring areas of dispute. One involves contractual interpretation: whether the rates reflected in MRFs match negotiated agreements, fee schedules, or value-based arrangements—or whether something got lost between the handshake and the spreadsheet. Another involves parity and nondiscrimination claims, where experts compare reimbursement structures across provider types or service categories using MRF-derived data.

Experts are also frequently asked to weigh in on methodological disputes—such as how data should be extracted, how missing or inconsistent fields should be handled, and how far one can reasonably push conclusions drawn from MRFs. In payer–provider conflicts, expert testimony often helps clarify whether MRF disclosures reflect actual payment practices or simply theoretical rate constructs that look good on paper but do not ride out well in the real world. Questions of regulatory compliance, including alignment with transparency-in-coverage requirements and downstream contractual obligations, only add to the need for clear, plain-language explanation.

The takeaway for attorneys is straightforward, even if it is not especially satisfying. MRF disputes are rarely about the data alone—they are about interpretation, context, and accepted industry practice. As courts see more of these cases, expert witnesses who understand healthcare contracts, reimbursement mechanics, and the practical realities behind MRF construction will become indispensable. Preferably, they can explain it all clearly—and without insisting that the spreadsheet speaks for itself, because it usually does not.
