A claim is submitted, and weeks later it comes back rejected. The service was delivered, the clinical care was appropriate, and the practice is out of pocket for reasons that have nothing to do with medicine.
Claim rejection is overwhelmingly an administrative failure, and it happens at predictable points.
Verify enrolment before the encounter, not after
The most common cause is a patient whose cover had lapsed, changed plan, or did not include the service. Checking at the desk, before the consultation, costs a few minutes. Discovering afterwards costs the whole claim.
Record what was verified and when. "We checked" is not defensible; a dated note naming who confirmed what is.
Authorisation before the service
Where pre-authorisation is required, obtaining it afterwards is usually impossible. This is the single largest avoidable loss in most practices. Build it into the workflow so that a service requiring authorisation cannot be scheduled without the reference recorded against the appointment.
Keep the reference number, the date, the name of the person who gave it, and the channel it came through. When a claim is queried months later, that record is the whole of your case.
Documentation has to support what was billed
A claim for a procedure needs a note describing that procedure. A claim for a consultation needs a note that reflects the complexity billed. This sounds obvious and it is the second most common rejection reason, usually because the clinical note was written for clinical purposes and never checked against what was submitted.
An EMR helps here only if the billing is generated from the record rather than typed separately. Where the two are entered independently, they will disagree.
Submit within the window
Every HMO has a submission deadline. Claims batched and sent when someone gets round to it will periodically miss it, and a late claim is simply lost income with no appeal.
Submit on a fixed schedule, weekly rather than monthly, so a delay in one batch does not push anything past a deadline.
Track what happens to every claim
Practices routinely know what they billed and not what they were paid. You need a view of claims submitted, claims paid, claims rejected with the reason, and claims neither paid nor rejected, which is the category that quietly grows.
Reconcile payments against claims rather than against a total. A payment that arrives as a lump sum against many claims hides partial payments unless it is broken down.
Rejections are a report, not a nuisance
Group your rejections by reason for a quarter. The list is almost always short and repetitive, and it points directly at the step in your process that needs fixing. Practices that do this once usually find that a handful of process changes remove the majority of their rejections.
Appeal properly
Many rejections are reversible with the right documentation attached. Have a defined route: who reviews rejections, within what period, and what evidence is gathered. Unappealed rejections are a decision to write off income, and it should at least be a deliberate one.
