check_price — Compare a charge with Medicare's rate for one service
Compare a charge with Medicare's rate for one service. For when someone asks whether a charge is high or what Medicare pays, for example "I was charged $450 for a 99213 office visit in Texas, is that too high?" or "what does Medicare pay for an MRI of the knee?". Takes the billing code if they have it, otherwise the service in plain words as q. Returns Medicare's 2026 rate for the state (or the city's own pricing area when city is given) in medicare_2026, the amount providers typically billed in 2024, and how many times the Medicare rate the charge is. For care in a hospital, hospital_facility_2026 gives Medicare's national rate for the hospital's own facility fee and comparison.compared_with says what the charge was set against. Dental work has no Medicare rate and returns 404 with a pointer to a free dental cost source.

}search_services — Find billing codes and Medicare rates by plain words
Find billing codes and Medicare rates by plain words. For when someone describes a service but has no code, or asks what a code means, for example "what's the code for a colonoscopy?", "how much does Medicare pay for a chest x-ray in Ohio?" or "what is code 99214?". Returns up to eight matching codes with Medicare's typical allowed and billed amounts.

}check_whole_bill — Check several lines of an itemized bill at once
Check several lines of an itemized bill at once. For when someone reads out or pastes several lines from an itemized bill, for example "my ER bill has 99284 for $2,500, 85025 twice for $120 and 36415 three times, does anything look off?". Takes the lines as code, optional x and units, then the amount. Returns each line against Medicare's rate, totals, and questions_to_ask: repeated codes, units above Medicare's automated daily limit, the highest visit levels, hospital clinic facility fees and charges far above what providers typically bill. Lines of a hospital bill (any bill with an ER visit on it, or setting=facility) are compared with Medicare's hospital outpatient rate plus the doctor's part; each such line says compared_with.

}look_up_hospital — Whether a hospital is nonprofit, for financial assistance
Whether a hospital is nonprofit, for financial assistance. For requests like "is St. Luke's in Boise a nonprofit?" or "does this hospital have to offer charity care?". Returns how Medicare lists the hospital's ownership (nonprofit, government, for-profit), its city and main phone number, and what that means for financial assistance. Nonprofit hospitals must have a financial assistance policy.

Returns a letter as plain text with [brackets] for anything not given, tips, and the user's No Surprises Act and Good Faith Estimate rights with official CMS links. It never sends anything.
