Inclusion criteria:

Guides and FAQs in this topic, plus the Substrate product that executes the workflow.

Honest limitations: Substrate does not replace a clearinghouse, EHR, or full-cycle BPO. It automates post-submission AR (status, appeals, posting, eligibility) and still routes clinical edge cases to staff. Coding, CDI, and patient-facing billing are out of scope.

Updated August 2026

What is appeals and denials automation?

Denial prevention flags issues before submission. Appeals automation recovers dollars after denial by retrieving records, validating payer policy, and filing through portals. Buyers comparing Substrate AI, AKASA, Waystar, Cohere Health, FinThrive, Innovaccer, Infinx, MD Clarity, Honey Health, and Adonis should separate prevention tools from recovery agents. Substrate retrieves EHR documents and files medical records and medical necessity appeals without replacing the EHR.
