Before You Pay a Medical Bill, Check It
In the ER I see what happens after the visit: a bill that makes no sense. Here is a simple 3-step way to check any medical bill, and what to do if insurance says no.


In the emergency department, my job ends when the patient goes home. For many patients, a second problem starts a few weeks later: a bill that makes no sense.
Billing advocates estimate that up to 80% of hospital bills contain errors. That is an advocacy estimate, not a peer-reviewed number, and published counts range from roughly 49% to 80% depending on how errors are counted. Either way, a few minutes of checking is worth it.
A simple 3-step method
Physician and bill expert Dr. Virgie Bright Ellington, MD, author of What Your Doctor Wants You to Know to Crush Medical Debt, teaches a method I recommend to anyone holding a medical bill:
- Get the itemized bill, with a billing code for every charge. Never pay from the summary.
- Check every line against what happened, your insurance statement and what Medicare pays for the same code.
- Call back to fix errors, ask for a fair price and set up an interest-free payment plan you can afford.

I turned her method into a free guide with a list of common errors to look for and a short phone script: How to check a medical bill before you pay it.
If insurance says no
A denial letter is not the final word. Ask why it was denied, let your doctor's office appeal first, then file your own appeal and, if needed, ask for an independent external review. For most plans, federal rules give you at least 180 days to file the first appeal, and your insurer must accept the external reviewer's decision.
Part 2 has the full plan, a deadline table for each type of coverage and a sample letter you can copy: How to appeal a health insurance denial.
Both guides are free, credited to Dr. Virgie, and for education only, not legal, financial or medical advice. In an emergency, call 911. Get care first and deal with the bill later.
