1. Request itemized bill + EOB within 30 days (patient right under federal law).
2. Verify EOB vs. bill--spot discrepancies like denied services.
3. Check No Surprises Act for out-of-network ER/protections (limits to in-network rates).

How to Read & Decode Your Medical Bill (EOB, Itemized Breakdown, Codes)

Medical bills use jargon: "chargemaster" rates (list prices, often 10x actual paid), deductibles (your yearly out-of-pocket before insurance kicks in, avg. $2,631 for small firms), facility fees (hidden "room charges" adding 45%+ to bills, CHIR). Always request an itemized bill--hospitals must provide it free.

DIY Checklist:

• Match dates/services to records.
• Lookup CPT/HCPCS codes (e.g., 99213 for office visit) on CMS site.
• Spot facility fees in ER bills (e.g., "clinic services").
• Total: Charges - Adjustments = Patient Responsibility.

Mini Case Study (CHIR): ER visit billed $5K; itemized revealed $3K facility fee. Patient negotiated to $500 after EOB match.
