Medigami runs a server-side PHI redactor before any downstream LLM call when scan_bill is invoked from the public SKU, but best practice is to redact client-side before passing the bill through an LLM tool call. For your own bill only — this tool is not for reviewing someone else's claims. WHEN TO USE: User pastes or uploads a medical bill, EOB, itemized statement, hospital charge summary, or similar.

Server-side PHI scrubber runs before any storage; the public aggregate contains only coded fields (insurer_canonical, denial_reason_code, state, cpt_category, dollars_bin, days_to_resolution_bin).

Scope note: this tool confirms the number is well-formed — it does NOT verify current registration status or the specific controlled-substance schedule the holder is authorized to prescribe. Authority verification requires a licensed DEA data broker (DEA ARCOS, RxMix). WHEN TO USE: Checking if a provider's DEA registration covers a specific controlled-substance CPT. WHEN NOT: For non-controlled-substance claims. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `medigami`: ```json { "permissions": { "allow": [ "mcp__medigami__optimize_prescription", "mcp__medigami__analyze_glp1_pathways", "mcp__medigami__resolve_denial", "mcp__medigami__explain_appeal_success", "mcp__medigami__lookup_icd10", "mcp__medigami__lookup_cpt", "mcp__medigami__lookup_npi", "mcp__medigami__verify_dea_authorization", "mcp__medigami__lookup_provider_taxonomy", "mcp__medigami__resolve_codes", "mcp__medigami__get_appeal_deadline", "mcp__medigami__get_venue", "mcp__medigami__medigami_roast" ], "ask": [ "mcp__medigami__scan_bill_for_errors", "mcp__medigami__generate_appeal_letter", "mcp__medigami__verify_attestation", "mcp__medigami__watch_appeal_outcome", "mcp__medigami__watch_claim_denial", "mcp__medigami__format_citation", "mcp__medigami__submit_denial_letter", "mcp__medigami__verify_mcp_response", "mcp__medigami__format_medigami_citation", "mcp__medigami__estimate_appeal_success", "mcp__medigami__maximize_recovery", "mcp__medigami__negotiate_bill_script", "mcp__medigami__batch_scan_bills", "mcp__medigami__code_conflict_detector", "mcp__medigami__fair_price_estimator", "mcp__medigami__price_variance_analyzer", "mcp__medigami__claim_consistency_checker", "mcp__medigami__bundling_violation_detector", "mcp__medigami__appeal_success_predictor", "mcp__medigami__generate_appeal_letter_v2", "mcp__medigami__negotiation_strategy_generator", "mcp__medigami__insurance_response_interpreter", "mcp__medigami__settlement_optimizer", "mcp__medigami__patient_cost_forecaster", "mcp__medigami__insurance_plan_optimizer", "mcp__medigami__cash_vs_insurance_optimizer", "mcp__medigami__financial_risk_exposure_model", "mcp__medigami__cpt_to_icd_mapper", "mcp__medigami__icd_to_cpt_mapper", "mcp__medigami__code_bundle_validator", "mcp__medigami__unbundling_detector", "mcp__medigami__cash_price_estimator", "mcp__medigami__zip_based_price_variance", "mcp__medigami__regional_price_benchmark", "mcp__medigami__specialty_price_benchmark", "mcp__medigami__inflation_adjusted_price_model", "mcp__medigami__deductible_impact_calculator", "mcp__medigami__coinsurance_simulator", "mcp__medigami__copay_model", "mcp__medigami__billing_charge_vs_allowed_delta", "mcp__medigami__price_anomaly_detector", "mcp__medigami__overpriced_service_detector", "mcp__medigami__market_price_distribution_model", "mcp__medigami__price_outlier_detector", "mcp__medigami__procedure_cost_decomposition", "mcp__medigami__price_recommendation_engine", "mcp__medigami__claim_duplicate_line_detector", "mcp__medigami__denial_reason_classifier", "mcp__medigami__appeal_argument_generator", "mcp__medigami__denial_response_builder", "mcp__medigami__dispute_case_builder", "mcp__medigami__evidence_pack_generator", "mcp__medigami__claim_rebuttal_generator", "mcp__medigami__appeal_escalation_path_finder", "mcp__medigami__payer_specific_appeal_templates", "mcp__medigami__denial_code_explainer", "mcp__medigami__claim_reconsideration_builder", "mcp__medigami__supporting_document_selector", "mcp__medigami__out_of_pocket_optimizer", "mcp__medigami__financial_exposure_model", "mcp__medigami__procedure_affordability_ranker", "mcp__medigami__treatment_cost_comparator", "mcp__medigami__bill_shock_predictor", "mcp__medigami__payment_plan_optimizer", "mcp__medigami__financial_assistance_finder", "mcp__medigami__patient_cost_explainer", "mcp__medigami__healthcare_budget_forecaster", "mcp__medigami__medical_spending_analyzer", "mcp__medigami__insurance_value_optimizer", "mcp__medigami__patient_financial_risk_score", "mcp__medigami__decode_denial", "mcp__medigami__medigami_odds", "mcp__medigami__medigami_deadline", "mcp__medigami__medigami_rate" ], "deny": [] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__medigami__optimize_prescription`: private-data, untrusted-input - `mcp__medigami__submit_denial_letter`: untrusted-input - `mcp__medigami__get_appeal_deadline`: untrusted-input - `mcp__medigami__get_venue`: private-data, untrusted-input ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T14:36:11.323Z, unchanged since 2026-10-22T14:36:11.323Z.
