Every dispute scenario, with the federal law behind it.

Upcoded ER visit — when the level on the bill doesn't match the chart

ER visits billed at a higher complexity level than the medical record supports are the most common billing-error pattern in the country. Federal coding rules let you dispute the level.

CMS Internet Only Manual, Pub. 100-04, Ch. 12, §30.6.1

Unbundled charges — when one procedure gets billed as several

Federal coding rules (NCCI edits) explicitly prohibit billing certain combinations of CPT codes together. When you see them on your bill, the federal benchmark gives you grounds to dispute.

42 CFR §414.40 / CMS NCCI Policy Manual

Wrong place-of-service code — facility billing for a non-facility visit

Place-of-service codes determine whether Medicare and most insurance pay the higher facility rate or the lower non-facility rate. A code mismatch can inflate a bill substantially.

42 CFR §414.22, CMS Place of Service Code Set

Duplicate charges — same service billed twice on the same bill

When the same service appears on a bill more than once — sometimes under slightly different code variants — federal billing rules give patients clear grounds to ask for the duplicate to be removed.

31 USC §3729 (FCA) / 42 CFR §424.32 (claim accuracy)

Phantom charges — services billed that you didn't receive

Charges for services, supplies, or medications you never actually got are some of the most common patient-side billing complaints. Federal consumer-protection law gives you the right to challenge them.

31 USC §3729 (FCA) / state UDAP statutes

Saline IV markup — when a $3 bag bills at $300+

Normal saline (sodium chloride 0.9%) is one of the most-marked-up items in hospital chargemasters. The federal Medicaid acquisition cost is publicly published; the gap to chargemaster is documented.

42 CFR §447.502 (NADAC) / 42 CFR §414.1 (PFS)

Surprise billing — out-of-network charges at an in-network facility

The No Surprises Act (2022) protects patients from out-of-network bills for emergency care and from out-of-network providers at in-network facilities. Federal law caps your liability.

Public Law 116-260, Division BB / 45 CFR §§149.1–149.510

Good Faith Estimate — when the bill is much higher than what they quoted

The No Surprises Act requires healthcare providers to give uninsured/self-pay patients a Good Faith Estimate. If the bill exceeds the estimate by $400+, you have federal dispute rights.

45 CFR §149.610 (GFE) / §149.620 (PPDR)

ER bill from out-of-network provider — federal protection at any hospital

The No Surprises Act mandates that emergency services be billed at in-network rates, regardless of which hospital you went to or who treated you.

PHSA §2799A-1 / 45 CFR §149.110

Charity care — your right to financial assistance at non-profit hospitals

ACA §501(r) requires non-profit hospitals to offer free or discounted care to patients meeting income criteria. Most patients never apply because most never know.

26 USC §501(r) / 26 CFR §1.501(r)-3 to -6

Presumptive eligibility — automatic charity-care qualification

Some non-profit hospitals' Financial Assistance Policies grant automatic charity-care eligibility to certain categories of patients without requiring an income application.

26 CFR §1.501(r)-4(b)(4) / FAP-implementation guidance

Insurance denied for 'not medically necessary' — your appeal rights

ERISA and ACA give every insured patient the right to appeal denied claims. Internal and external review processes are mandatory; insurers must follow specific timelines.

ERISA §503 (29 USC §1133) / ACA §2719 (42 USC §300gg-19)

Hospital won't send an itemized bill — your federal right to one

HIPAA §164.524 gives every patient the right to a copy of the bill in itemized form. If a hospital sends only a summary, you can demand the full itemization.

HIPAA §164.524 / 45 CFR §164.524

Get your medical record — 30-day federal right

HIPAA gives every patient the right to a copy of their medical record within 30 days. The chart is the foundation of any bill review or appeal.

HIPAA §164.524 / 45 CFR §164.524

Debt validation letter — the FDCPA tool every patient should know

When a medical debt is sent to collections, federal law gives you 30 days to demand validation. The collector must prove the debt is yours and accurate.

FDCPA §1692g / 15 USC §1692g

Negotiating a medical bill — the settlement offer

Self-pay medical bills are negotiable. Hospitals routinely accept 25–50% of the original balance for prompt-pay settlements. Federal law doesn't require it, but the practice is universal.
