Elizabeth Purdy focuses on helping providers recover revenue from denied and underpaid claims, with a particular emphasis on complex payer disputes, medical necessity denials, and audit-related recoupments.

She has significant experience analyzing medical records, plan language, CMS guidance, and payer policies to uncover coverage pathways and appealable issues that are often overlooked. Elizabeth approaches each case with both a legal and an operational perspective, allowing her to address not only the stated basis for denial but also the underlying issues driving the payer’s determination.

At Rivet Health Law, Elizabeth works directly with providers, billing companies, and healthcare organizations to challenge improper insurance determinations and build appeals that go beyond surface-level denial reasons. Her work includes commercial and government payer appeals, overpayment disputes, and high-value claims requiring detailed policy and clinical analysis.
