We make AppealHound. Read this page with that in mind. Every fact about another product links to the page on that vendor's own site we took it from, read on 24 and 27 September and 22 October 2026. Where a vendor does not say something, we write "not public" or "not stated", which is not the same as "no". If a fact here is wrong or out of date, tell us and we fix it.
The Main Differences
- Review. LunaBill says its agents draft and file the appeal. In AppealHound a person at the billing company approves every appeal before it goes out.
- Scope. LunaBill works portals, payer calls, denials, resubmissions and posting. AppealHound starts at the 835 and ends at an appeal your people approve.
- Setup. LunaBill connects to your EHR and clearinghouse. AppealHound needs the 835 file and nothing else.
