Tools

• calculate_liability ~346 tokens
  Stateless insurance math: given an allowed amount and a plan snapshot (deductible, coinsurance, OOP max), returns exact patient responsibility, plan payment, and the breakdown, plus p25/p75 scenarios. Use when you already have a dollar amount (e.g. from an EOB or a prior estimate).
• check_financial_assistance ~340 tokens
  Screen a household for hospital financial assistance (charity care): returns income as a percent of the federal poverty guidelines, the typical range hospital policies cover, what federal rules (IRS 501(r)) do and do not guarantee, and next steps. Use when a user asks whether they might qualify for
• compare_bill_amount ~379 tokens
  Compares one dollar amount from a medical bill or explanation of benefits with the typical allowed-amount range (low, median, high) for the same procedure in the same US state, and says whether it is below, within or above that range, with questions worth asking the billing office. Pass amount_type
• demo_estimate ~87 tokens

• estimate_procedure_cost ~454 tokens
  Returns the typical allowed-amount range (low, median, high) for one medical procedure in one US state, the usual billing components (facility, physician, anesthesia, pathology), and the data vintage. If the user chooses to give their own deductible, coinsurance and out-of-pocket figures, it also re
• find_providers ~246 tokens
  Lists up to 5 facilities in one US state that perform a procedure, with name, address and a pricing_status field: 'observed' means a negotiated rate is published in that facility's price transparency data, 'estimated' means only a state-level benchmark applies, 'none' means no price data. Dollar amo
• full_estimate ~266 tokens
  One call chaining procedure ontology + cost + providers + patient liability. Cheapest way (one metered request) to get the complete picture. Use `fields` to request a subset; liability requires the plan_* inputs.
• get_coverage ~270 tokens
  Insurance coverage rules for a procedure/carrier combination. aspect: 'summary' (status + plain English), 'prior-auth', 'cost-sharing' (deductible/coinsurance/ACA preventive), 'frequency' (how often covered, age rules), or 'triggers' (Pro plan: billing events that flip a $0 preventive claim to diagn
• get_procedure_details ~183 tokens
  Structured knowledge about one procedure. aspect='facts' returns LLM-ready billing rules and cost drivers (best for grounding an answer); 'bundle' explains which separate bills to expect (facility, physician, anesthesia...); 'full' returns the complete ontology.
• get_provider ~100 tokens
  Public profile for a single provider by 10-digit NPI number: name, specialty, address, entity type.
• list_carriers ~85 tokens
  All insurance carrier keys supported by the coverage tools (aetna, cigna, bcbs, medicare, ...). Works on the Free plan — also a good API-key sanity check.
• list_procedures ~118 tokens
  The full CostKits catalog: 30 procedures with slugs, display names, categories, and CPT codes (paginated).
• resolve_procedure ~137 tokens
  Maps a free-text procedure name ('knee mri', 'gallbladder removal') to a CostKits catalog slug with a confidence score. Returns best_match and alternatives; best_match is null when the procedure is not in the catalog.
