For out-of-network doctors at an in-network hospital, ER bills, duplicate charges and coding errors. Federal surprise-billing rules may already cap what you owe. Send us your bill (names and ID numbers blacked out) and within 48 hours you get a plain-English summary, your deadlines, a ready-to-sign dispute letter and the next step if they refuse. You review, sign and send it yourself. Nothing worth disputing? Full refund. Pushback is not a law firm and does not give legal or medical advice.
