Denial letters are written to end conversations; appeals exist because they often shouldn't. A meaningful share of denials — especially coding errors, "not medically necessary," and documentation gaps — get overturned when someone answers the stated reason with evidence instead of outrage. This skill decodes what the denial actually claims, matches each claim to the evidence that answers it, and writes the appeal that reads like it was drafted by someone who will escalate.
Claim Denial Decoder is a community-contributed Claude Code skill in the operations sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/claim-denial-decoder/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when someone asks 'my insurance claim was denied what do I do', 'decode this denial letter', 'can I appeal this denial', or 'write my insurance appeal'. Produces the denial decode with overturn-likelihood framing, the evidence checklist, the point-by-point appeal letter, and the escalation ladder past the insurer.
The Claim Denial Decoder Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
