Short payments that look like normal adjustments
If your billing system doesn't have your payer contract rates loaded, it has no way to know when a payment comes in short. A payer can pay less than the contract says, and the payment still posts cleanly, with the shortfall written off as an ordinary contractual adjustment.
Nothing gets denied and nothing looks wrong. The claim closes, the balance goes to zero, and nobody notices. Sometimes a commercial payer pays the same fraction of the contracted rate on every code, month after month, and it only shows up when someone holds the payments up against the contract itself.
Warning signs
- Nobody can find the signed contract or the current fee schedule for one of your larger payers.
- Your system has no expected payment loaded, so every adjustment looks the same.
- Contractual adjustments for a payer have crept up, and no one can say why.
What it costs you
Every short payment becomes a permanent write-off. Because it looks routine, it repeats on every claim until someone checks, and recovery is limited by the dispute window in the contract.
What to do
- Get each payer's signed contract and fee schedule, with effective dates. Rates change, so you need to know which schedule applied on each date of service.
- Compare what was actually allowed and paid to the contract rate, code by code.
- Look for the same short-pay percentage across many codes. That pattern points to a setup or loading problem on the payer's side, not a one-off.
- Separate out plans the contract doesn't cover. A payer's Medicare or Medicaid product may have its own rates.
- Account for "lesser of billed or contract" terms. If your charge is below the contract rate, a lower payment may be correct.
- Know the contract's dispute deadline, and send your findings before it passes.
Ask your billing team
"For each payer, do we check what was paid against what the contract says it should pay?"
What fixing it gets you
Payments you can trust, short payments caught while you can still dispute them, and contract terms that actually show up in your cash.
