Healthcare: Claims Denial Appeal Preparation with Claude Code: MCP Tool Boundary

A production playbook for claims denial appeal preparation in healthcare operations using Claude Code: mcp tool boundary, run-scoped inputs, logs, typed results, and artifacts.

Audience: Revenue cycle teams appealing payer denials

The problem

Revenue cycle teams appealing payer denials need claims denial appeal preparation to run repeatedly against EOBs, denial letters, medical records, payer policies, and appeal templates. In healthcare operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.

Implementation path

Expose only the MCP tools needed for claims denial appeal preparation, validate tool arguments, keep credentials in the owning service, and log each call outside the sandbox.

Tradeoffs and failure modes

Narrow tool boundaries reduce agent flexibility, but make the integration reviewable and supportable. For claims denial appeal preparation, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
