By the end of this guide, you'll be able to use Claude to draft structured clinical justification letters for RAC/MAC audit appeals in 20–30 minutes instead of 2–3 hours. You'll have a repeatable process that produces consistent, guideline-grounded appeals — and you'll have a reusable template for your most common denial categories.

• A Claude account — free tier works for occasional use; {{tool:Claude.plan}} ({{tool:Claude.price}}) gives you faster responses and longer document handling
• The RAC or MAC denial letter (for the denial rationale — you'll de-identify any case-specific details before using AI)
• De-identified clinical facts for the case: diagnosis, key clinical indicators, treatment, timeline — NO patient name, MRN, date of birth, or other PHI
• Time needed: 30–45 minutes per appeal draft
• Cost: Free (Claude free tier) or {{tool:Claude.price}} for {{tool:Claude.plan}}
