No Surprises Act: Since Jan 1, 2022, shields emergency/out-of-network bills. Dispute if billed ≥$400 over good faith estimate via IDR. No patient involvement in provider-insurer fights (CMS/CFPB). 2026 ACA params reinforce Marketplace stability but don't alter core deadlines.

ERISA/ACA Appeals: Employer plans require internal appeals; expedited decisions in 4 business days (CMS). External review if denied.

HIPAA: No direct dispute timelines, but mandates access to records aiding disputes (HHS).
