Guide 1: Understanding Your Medical Bill
What is a Medical Bill? (and why does it look like secret code?)
After a doctor's visit, you'll receive a medical bill from your provider — whether that's a doctor, hospital, or clinic. It can arrive in your patient portal (Electronic Health Record), by mail, and often times weeks after your appointment.
Your bill summarizes the services you received, what your insurance paid (if applicable), and what you owe. It's worth reviewing carefully because billing errors are common, and you may not owe as much as the bill suggests.
One important distinction: a medical bill is not the same as an Explanation of Benefits (EOB). An EOB comes from your insurance company and is for your records only — it is not a request for payment. It is a detailed account of what the services received, costs covered by insurance, and the patient's remaining responsibility.
What's on Your Bill
Patient Information
Your name, address, SSN, date of birth, and other identifying details. Always verify this first — errors here can mean you're being billed for someone else's care.
Service Details
A breakdown of everything you received during your visit:
Date of Service — when you were seen
Description of Service — the procedures, tests, or treatments provided
CPT Codes — five-digit codes assigned to each service. These are the industry standard for describing medical procedures. Guide 2 covers how to read them, along with other common codes like ICD-10 and HCPCS.
Charges
Total Charges — the full amount billed before any adjustments
Adjustments — reductions applied by the provider. These can be significant and are sometimes negotiable — BillCare can help you review them.
Insurance Payment — what your insurer has paid or is expected to pay. Errors here are common; make sure this matches your plan documents.
Patient Payment — any amount you've already paid, such as a copay
Balance Due — what you still owe
Note: It's not unusual to receive multiple bills for a single visit if different providers were involved (for example, a surgeon and an anesthesiologist billing separately).

Next Steps: What to Do When You Get a Bill
Request an itemized bill. Providers are legally required to provide one. This gives you a line-by-line breakdown of every charge — and is the first thing BillCare will ask for.
Check your personal information. Confirm that all names, dates, and identifiers are correct.
Cross-reference your EOB. Make sure what your insurer paid matches what's reflected on the bill.
Keep records. Save copies of your bills, EOBs, and any correspondence with your provider or insurer.
If something doesn't look right, don't pay it without questioning it first. BillCare is here to help you work through it.
