Appeal Builder

The Appeal Builder generates compliant medical billing appeal letters from denial code, payer type, specialty, and clinical details. AI-assisted intent classification runs locally in the browser; deterministic, citation-verified letter assembly produces the final output. No patient data is transmitted to any server — all processing is local. The output is a formatted letter ready to submit to the payer.

The builder works from the CARC code on the remittance advice. Select the denial code and the builder identifies the correct regulatory framework, argument category, opening argument, and closing demand based on the specific statutory basis for contesting that denial category. Medical necessity denials cite applicable LCDs, NCDs, and clinical society guidelines. Authorization denials cite ACA §2719, ERISA §503, and 29 CFR §2560.503-1. Output includes copy-to-clipboard, .txt download, and .rtf export.
