IDR deadline calculator
Compute your open negotiation and federal IDR initiation deadlines — in business days, with weekends and U.S. federal holidays excluded.
How the dates are calculated
Business days exclude Saturdays, Sundays, and U.S. federal holidays (including observed dates when a holiday falls on a weekend). The open negotiation initiation window is the 30-business-day period beginning on the day the initial payment or notice of denial is received. The open negotiation period is the 30-business-day period beginning on the date open negotiation is initiated. The federal IDR initiation window is the 4-business-day period beginning on the business day after the open negotiation period ends. The cooling-off period runs 90 calendar days from a payment determination; claims whose initiation deadlines lapsed during the cooling-off period may generally be initiated during the 30-business-day period after it ends. The No Surprises Act regulations do not define “business day”; excluding federal holidays reflects standard federal practice and CMS operational practice. Verify computed dates against the federal IDR portal.

Timelines depend on the facts of each dispute and current CMS guidance; parties are responsible for verifying all dates in the federal IDR portal before relying on them.
