The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
insurer_appeal_outcomes ~327
Does appealing a denied health-insurance claim work? Marketplace issuers ranked by the share of appeals that were OVERTURNED in the patient's favour, plan year 2026. Answers "is it worth appealing a denied claim", "what percentage of insurance appeals succeed", "how often does <company> reverse a denial", and which insurer most often changes its mind. Returns internal appeals (decided by the insurer itself) and external appeals (decided by an independent reviewer) separately, with how many were filed, how many were overturned, and the overturn percentage — the two differ a lot and the external number is the independent one. Sourced from the CMS Transparency in Coverage Public Use File; covers HealthCare.gov states only, so state-run exchanges such as California and New York are not present.
| Name | Type | Req | Description |
|---|---|---|---|
| appeal_type | string | – | "internal" (default, decided by the insurer) or "external" (decided by an independent reviewer). |
| limit | number | – | How many issuers to return (default 20, max 200). |
| market | string | – | Restrict to issuers participating in "medical" / "QHP", "dental" / "SADP", or "SHOP". Selects issuers rather than splitting their figures. Omit for all. |
| order | string | – | "highest" (default) ranks the most-overturned first; "lowest" ranks the least. |
| state | string | – | Two-letter US state code to filter by, e.g. "TX". Omit for all states. |
No output schema declared.
No examples provided.
insurer_denial_coverage ~102
What this data covers before you rely on it: the plan year, how many issuers and states are present, which states are included, and the counts of issuers whose denial or appeal figures CMS suppressed. Use to check whether a state or insurer is in scope at all, and to tell "we hold no data for this state" apart from "this state's insurers deny nothing" — the CMS Transparency in Coverage file covers HealthCare.gov states only.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
insurer_denial_profile ~196
Everything reported for ONE named health insurer: claims received and denied in and out of network, the denial rate, and both internal and external appeal outcomes, for plan year 2026. Use when a caller names a company — "how often does Ambetter deny claims", "Blue Cross denial rate in Texas", "what happens if I appeal with Oscar". Matches on the insurer's name and is forgiving about punctuation, case and partial names; an issuer selling in several states returns one entry per state, since CMS reports these figures per issuer per state. Sourced from the CMS Transparency in Coverage Public Use File; covers HealthCare.gov states only.
| Name | Type | Req | Description |
|---|---|---|---|
| insurer | string | yes | Insurer name or part of one, e.g. "Ambetter", "Blue Cross Blue Shield of Texas", "oscar". |
| state | string | – | Optional two-letter state code to narrow a multi-state insurer, e.g. "TX". |
No output schema declared.
No examples provided.
insurer_denial_rates ~359
Which health insurers deny the most claims — US marketplace issuers ranked by the share of in-network claims they denied, for plan year 2026. Answers "what percentage of claims does my insurance company deny", "which insurer denies the most", "how often does <company> deny claims", and comparisons between insurers in a state. Returns each issuer with claims received, claims denied, the denial rate as a percentage, and how many marketplace plans it offers. Filter by state (two-letter code) or by market — medical plans (Individual QHP), standalone dental (Individual SADP, which denies at much higher rates than medical), or small-group SHOP; the market filter selects which ISSUERS to include, since CMS publishes these counts per issuer rather than per market. Sourced from the CMS Transparency in Coverage Public Use File, which insurers report into under federal rule; covers HealthCare.gov states only, so issuers on state-run exchanges such as California and New York are not present.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | – | How many issuers to return (default 20, max 200). |
| market | string | – | Restrict to issuers participating in a market: "medical" / "QHP", "dental" / "SADP" for standalone dental, or "SHOP" for small-group. Selects issuers; it does not split an issuer's claim counts, whic… |
| order | string | – | "highest" (default) ranks the biggest deniers first; "lowest" ranks the smallest. |
| state | string | – | Two-letter US state code to filter by, e.g. "TX", "FL". Omit for all states. |
