Returns the Medicare national-average non-facility allowed amount for a CPT or HCPCS procedure code from the CMS Physician Fee Schedule. Useful for benchmarking what a hospital or clinic billed against what Medicare reimburses. Free, no authentication required.

Returns hospital metadata from CMS data: name, location, ownership type, CMS overall rating (1-5 stars), and 501(c)(3) charity-care eligibility. Useful when a patient mentions a specific hospital and wants to know the facility's federally-published quality profile and whether charity care is available. Free, no authentication required.

Returns a summary of one MediBill Saver dispute scenario: title, category, the federal statute backing the patient's right to dispute, and a link to the full scenario page (which contains the how-to-spot checklist and sample dispute language). Useful when a patient asks 'how do I dispute X' or 'what is HIPAA §164.524'. Free, no authentication required.

Runs a full audit on a medical bill — cross-references every charge against six federal data sources (CMS PFS, NADAC, HPT, NCCI, Hospital Compare, IRS Pub 78) and identifies potential billing errors plus the federal statutes the patient can cite. Returns a free preview (severity, totals, issue count). The full report with line-by-line breakdown and up to 5 ready-to-mail dispute letters requires payment ($19.97 single audit, or covered under Family/Pro subscription). Returns a unique unlock URL for completing payment.
