Step 1 · 501(r) Charity Care Check 501(r) AGB Cap: $166,478 (274% FPL)

Statutory 501(r) AGB Cap Limits Bill to $166,478

At 274% FPL (201%–400% FPL tier), 26 U.S.C. § 501(r)(5) caps FAP-eligible bills at Amounts Generally Billed (50.0% of gross = $166,478).

Step 2 · Cash vs. Insurance Arbitrage Save $99,887 Paying Cash

Self-Pay Cash Rate ($233,068) Beats Your Bill

Northwestern Medicine Central Dupage Hospital's published 45 CFR § 180 self-pay cash rate is $233,068 (vs. $34,194 commercial insurer median). Ask billing to reclassify the visit to prompt-pay self-pay if it beats your deductible.

Negotiate Toward $30,775 Fair BaseRate ($23,504 Medicare)

Your bill ($332,955) is $302,180 above the denoised Fair BaseRate ($30,775) and 14.2× the $23,504 Medicare rate.
