Frequently asked

How does the CPT code audit work?

We parse every procedure code from your bill or EOB, cross-reference against Medicare reimbursement rates and CPT bundling rules, and flag codes that are upcoded, duplicated, or unbundled. Each issue comes with the specific dollar amount overbilled.

What is the No Surprises Act?

The No Surprises Act (42 U.S.C. § 300gg-111), effective January 2022, bans balance billing for emergency services and out-of-network care at in-network facilities. Violations are common — hospitals routinely send bills they are legally prohibited from collecting.

Will the dispute letter actually work?

Dispute letters citing specific regulatory violations and CPT bundling rules have a significantly higher resolution rate than generic requests. Hospitals have billing compliance departments that respond to documented regulatory claims. Many issues resolve within 30-60 days.

What if I have Medicare or Medicaid?

The audit works for all insurance types including Medicare, Medicaid, and commercial insurance. The benchmarks and violation checks are calibrated for your specific insurance type when you provide it.

Is Medical Bill Defender worth $149?

Medical billing advocates charge $300–$600 per case. At $149, you get the same systematic audit. The average recovered amount is $1,300 — this pays for itself 8× on a typical hospital bill.

What if I don't find any errors?

Roughly 1 in 3 bills has an error. If your audit returns clean, you get peace of mind and a benchmarked cost comparison — useful if you plan to dispute future bills or negotiate a payment plan.
