The questions billers call payers about.
Written for people who work claims for a living, not for search engines. Where a rule genuinely varies by payer, plan or state, these pages say so instead of printing a number that would be wrong for most of your claims.
How to check a Medicare claim status by phone
Which contractor actually holds the claim, why a Medicare Advantage claim is somewhere else entirely, the identifiers you need to authenticate, and why the representative keeps sending you back to the IVR.
What does denial code CO-97 mean?
Bundled into another already-adjudicated service, and a contractual write-off you cannot bill the patient for. How to tell whether the bundling was correct before you rework it.
How long do I have to appeal a denied claim?
There is no single deadline. The Medicare fee-for-service levels, why commercial windows live in your contract, what ERISA requires, and the three clocks billers routinely confuse.
How to get a call reference number from a payer
The most valuable thing you leave a payer call with. How to ask, what to log alongside it, what to do when the payer says there isn't one, and what it does not protect you from.
Why payer portals don't show claim status
Rejections that never became claims, carve-outs and delegated entities, searches keyed to the wrong tax ID, and a status code set too coarse to explain a denial.
How to reach a live rep at a payer faster
What genuinely shortens a payer call, which tactics stopped working, why you should measure your own best-time-to-call instead of trusting folklore, and what none of it fixes.
Your billers already know all of this
The knowledge is not the bottleneck. The hold time is. HoldForYou queues the payer call, works the IVR, waits, talks to the representative, and hands back a structured result.
HoldForYou for billing teamsThese pages are general information for billing professionals. They are not legal, coding or billing advice, and no page here lists payer phone numbers — use the provider-services number on the member's card and your own payer grid.
