# New York's Surprise Bill Law Gives You 3 Years. Federal IDR Gives You 30 Business Days.
Most of what I tell practices about dispute deadlines is bad news: the federal clock is short and unforgiving, and claims expire while EOBs sit in queues. This article is the good news, and it is specific to New York.
Two systems, two clocks
New York runs a bifurcated system. Out of network claims under self insured employer plans route to the federal IDR process, with its tight chain of windows: 30 business days from initial payment to initiate open negotiation, then 30 business days of negotiation, then 4 business days to file. Miss any link and the claim is gone.
But claims under fully insured, New York state regulated plans fall under New York's own surprise billing law, one of the oldest and most provider tested in the country. And New York's framework gives providers dramatically longer to act: payment disputes on state regulated claims can be challenged years after the payment, with a lookback period that reaches back roughly three years.
What that means in plain billing terms
Somewhere in your practice's archive sit out of network claims from 2023, 2024, and 2025 that were underpaid, never disputed, and written off as finished business. If those claims ran through fully insured New York plans, a meaningful share of them are not finished. They are dormant, and the state pathway can still reach them.
I have spent 20 years in surgical billing and I can count on one hand the New York practices I have met that systematically audit their historical out of network claims for state pathway eligibility. The federal process gets the attention because the deadlines are loud. The state lookback gets ignored because old EOBs feel like settled history. Settled is not the same as correct.
How a resurrection review works
The work is archaeological but mechanical. Pull the historical out of network EOBs. Determine plan funding on each, self insured claims are federally governed and their windows have closed, fully insured state regulated claims are candidates. Score the candidates by underpayment size against the dispute economics. File the ones worth filing through the state pathway, with the same evidence discipline as any current dispute: benchmark rates, case complexity, credentials, payer history.
A surgical practice with a few years of New York volume often finds the dormant pile is the largest single recovery opportunity it has, larger than the current month's disputes, because it is three years of write offs concentrated in one review.
The current claims still need the fast clock
None of this excuses the federal windows. Your self insured claims still live and die in business days, and a practice that chases the lookback while today's claims expire has traded new money for old. My team runs both: current claims tracked from EOB intake, historical claims audited for state pathway eligibility, with New York routing decided claim by claim.
If your practice has New York out of network volume, the review to request is specific: send recent EOBs for the current pipeline, and ask us about the historical audit. We will tell you what the archive is worth before you spend anything pursuing it.
