What goes in an open negotiation notice?

The parties and contacts, the disputed items and services with dates and codes, the payer's initial payment, and your proposed payment amount, all on the standard federal form.

Where do I send the open negotiation notice?

To the contact the payer designated for open negotiation in its No Surprises Act disclosures on the remittance. Keep dated proof of the send, because the negotiation window and the arbitration deadline both compute from it.

Should my proposed amount be my billed charges?

No. Arbitrators may not consider billed charges, so an offer framed on them signals weakness later. Propose from the statutory factors and the published record, which shows typical awards around 4.7 times the qualifying payment amount.

How to send an open negotiation notice, step by step

Complete the standard open negotiation notice with the disputed claims, dates, service codes, the payer's initial payment, and your proposed amount, then send it to the payer's designated contact within 30 business days of the payment or denial, and keep dated proof. The 30 business day negotiation window runs from the send.

Step one: confirm the claim qualifies

The notice only matters for claims the No Surprises Act covers: emergency services, or out-of-network care at an in-network hospital or ambulatory surgery center. Check eligibility before anything else, because a notice on an ineligible claim starts a process that ends with a rejected dispute. Then check the clock: you are inside 30 business days of the payer's initial payment or notice of denial, or you are done before you start.

Step two: complete the standard form

The federal departments publish the standard notice. It wants the parties and contacts, the patient and plan information, the items and services in dispute with dates of service and codes, the amount the payer paid, and your proposed out-of-network rate. The proposed amount deserves thought, not reflex: it frames the negotiation, and if the dispute proceeds, your arbitration offer will be judged on credibility under the statutory factors. Anchoring to the published record beats anchoring to billed charges, which arbitrators may not even consider.

Step three: send it where the payer said

Payers must provide contact information for open negotiation with their required No Surprises Act disclosures on the remittance. Send the notice there, not to a general claims address. CMS has finalized changes that move open negotiation into the federal IDR portal as the new process phases in; once your disputes run through the portal flow, the send and the window become system events both sides can see.

Step four: keep the proof, calendar the deadlines

The send date starts the 30 business day negotiation window, and the window's close starts the 4 business day period to initiate arbitration. Keep dated proof of the send, calendar both dates the moment the notice goes out, and assign the filing decision to a named owner. The most common failure in the whole No Surprises Act process is not losing an arbitration, it is sending a good notice and then missing the filing window.

If you have more than a few of these

One notice is a form; forty a month is an operation. Claims against the same payer for the same or similar services within a 30 business day window can later be batched into one arbitration, so notices should be sequenced with the batch in mind. That is process design, and it is the part Lido IDR runs for providers end to end, for a flat fee per arbitration.
