IDR deadline calculator

Enter the date of the payer's initial payment or denial. Business days exclude weekends and federal holidays.

Initial payment / denial date

Open negotiation notice sent (optional)

Guidance only — the statutory clocks are counted in business days and can be affected by the date a payer receives a clean claim, weekends, and holidays. We verify every deadline claim by claim before filing.

How the clocks work

Open negotiation notice: within 30 business days of the initial payment or denial.
Negotiation period: 30 business days from the date the notice is sent.
IDR initiation: within 4 business days after the negotiation period ends, in the federal portal.
Offers: within 10 business days of IDR entity selection.
Payment: within 30 calendar days of the determination.

Business days exclude Saturdays, Sundays, and federal holidays. State processes (Texas, New York, New Jersey and others) run on their own clocks.

We track every clock on every claim automatically. Free claims review.
