Medicare & Billing
Medicare claim rejections
Most Medicare rejections can be prevented: a mistyped card number, the wrong IRN, an expired referral, a cap already used elsewhere, or a duplicate. The ones you can't prevent need to end up in a worklist with a clear next step, not left unread in a report.
Common challenges
What teams struggle with
Raw explanation codes
Medicare returns numeric codes and short text that billing staff have to translate into an action themselves.
Resubmission duplicates
Correcting a declined claim and resubmitting it under a new reference makes the second attempt hard to reconcile.
Fixing one claim at a time
A wrong patient or provider detail fixed on one claim will cause the same rejection on the next one.
Lost revenue
Declines nobody deals with never become private invoices or corrected claims.
How we help
Practical solutions that ship
Grouped worklists
Declines are grouped by what needs doing (cap reached, referral, patient details, duplicate, provider) and sorted oldest first.
Fix at the source
Corrections are made to the patient or provider record, so future claims are right too.
Same-reference resubmission
Resubmitted claims keep their original reference so the attempts reconcile against each other.
Prevention
Check digit, referral and cap validation stop the most common rejections before submission.
Frequently asked
Questions about medicare claim rejections
What's the most common avoidable rejection?
In our experience, patient details: the card number, IRN or date of birth doesn't match Medicare's records. For allied health, caps already used at another provider come close behind.
