What data it sees

Do you need an account

No: the server works without sign-in

Checks a US medical bill against Medicare's published rates and drafts letters you can send. Look up a service by billing code (CPT or HCPCS, like 99213) or in plain words (like knee MRI), nationally or for a state, and compare a charged amount with what Medicare allows and what providers typically bill. Drafts letters to request an itemized bill, dispute a charge, ask for a self-pay discount or apply for hospital financial assistance.

check_priceCompare a charge with Medicare's rate for one service. Use 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?". Pass 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_servicesFind billing codes and Medicare rates by plain words. Use 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_billCheck several lines of an itemized bill at once. Use 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?". Pass 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_hospitalWhether a hospital is nonprofit, for financial assistance. Use for "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.
draft_bill_letterDraft a letter to a billing office for the user to send. Use for "help me dispute this bill", "write a letter asking for an itemized bill", "can I ask for a discount?" or "how do I apply for charity care?". 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.
