Top dispute types covered

Six common medical billing disputes, one federal-law-cited letter.

01

Out-of-network surprise charges

Patient received emergency or involuntary out-of-network care and was billed at out-of-network rates for services covered under their plan.

Cite: No Surprises Act 42 USC 300gg-111 — patient owes only in-network cost-sharing.

02

Balance billing

Provider bills the difference between the full charge and the insurer's allowed amount after a surprise-bill scenario.

Cite: No Surprises Act § 9816 (employer plans) / 42 USC 300gg-111 (individual/group) — balance billing is prohibited.

03

Coding errors

Wrong CPT/ICD-10 code applied (upcoding, unbundling, or a modifier stripped), inflating the charge or triggering a false denial.

Cite: 45 CFR 162 (HIPAA transaction standards) + payer contract — request itemized bill + corrected claim.

04

Duplicate billing

Same service, date, and provider billed twice; common after a claim resubmission or system conversion.

Cite: 42 USC 1395nn / 18 USC 1347 (False Claims exposure) — insurer must reverse the duplicate on written demand.

05

Denied claims

Insurer denied a covered service citing lack of medical necessity, wrong network tier, or a missing prior auth that the plan never required.

Cite: ACA § 2719 / 45 CFR 147.136 — internal + external appeal rights, 30-day urgent / 60-day standard deadline.

06

No Surprises Act violations

Provider or facility billed above allowed amounts, failed to give good-faith cost estimates, or applied an out-of-network rate where the Act prohibits it.

Cite: No Surprises Act (42 USC 300gg-111) — file with CMS No Surprises Help Desk.

Frequently asked

Medical billing dispute questions, regulation-cited.

Can a provider bill me more than my in-network cost-sharing for emergency care?

No. Under the No Surprises Act (42 USC 300gg-111), you owe only in-network cost-sharing for emergency services and certain non-emergency services at in-network facilities, regardless of provider network status.

My insurer denied a claim as "not medically necessary." What are my appeal rights?

Under ACA § 2719 and 45 CFR 147.136, you have the right to an internal appeal (30 days urgent / 60 days standard) and then a binding external review by an independent organization. Our letter cites both timelines.

I found a duplicate charge on my itemized bill. What do I do?

Request the itemized statement in writing (hospitals must provide one under most state laws) and identify the duplicate by date, CPT code, and dollar amount. A formal written dispute triggers the insurer's obligation to investigate and reverse the charge.

What if the provider and insurer both ignore my letter?

The escalation path is: (1) CMS No Surprises Help Desk for NSA violations, (2) your state Department of Insurance for coverage disputes, (3) DOL Employee Benefits Security Administration for ERISA plans, then (4) small-claims court for amounts within local limits. We track through each tier.
