In plain language

What this regime says.

Medicare and Medicaid cap what a provider may collect from a beneficiary, and the caps are much tighter than commercial ones. A provider accepting assignment may collect only the deductible and coinsurance; one that does not may not exceed the limiting charge of 115 per cent of the non-participating fee schedule amount; a Qualified Medicare Beneficiary may not be billed for Medicare cost sharing at all; and a Medicaid provider takes the programme payment as payment in full.

Who is covered

Medicare beneficiaries, Medicaid recipients, and people enrolled in both. Medicare Advantage enrollees are covered by the plan's own rules and a different appeals process under 42 CFR Part 422 Subpart M.

What you get

A bill limited to the statutory amount, a refund of anything charged above it, no liability for a denied service where no valid advance notice was given, and a five-level appeal that is free and has no minimum amount at its first two levels.

Where claims go wrong

  • Paying the difference between the provider's charge and Medicare's approved amount. For a participating provider there is no such difference to pay.
  • Not knowing about QMB status, or not mentioning it. The prohibition is absolute and one sentence usually resolves the bill.
  • Treating a denial as the end. Redetermination and reconsideration are free, have no minimum amount, and change a large share of decisions.
  • Accepting an Advance Beneficiary Notice at face value. Routine, vague or late notices do not shift liability.
  • Missing the 120 days for a redetermination. The clock runs from the Medicare Summary Notice, and good cause can extend it — but only if you ask.
The official claim route

Where a figure is indexed, converted or published by a regulator rather than fixed in the instrument, the provenance is recorded separately. Anything marked as a modelled estimate is exactly that — a model, not a statutory number.

What it imposes

Clocks, defences and the ladder.

A rule module builds these while it evaluates, because a limitation period depends on which forum is open to you. What follows is the structure this regime produces — deliberately with no dates and no figures, because those belong to your facts rather than to the law.
