Why Your HMO Claims Get Rejected in Nigeria (and How to Fix It)

For many Nigerian hospitals, the biggest hole in the budget is not unpaid patients — it is unpaid HMOs. Claims get rejected, underpaid, or simply lost, and because the loss is spread across hundreds of small claims, nobody notices the total. Here are the real reasons claims bounce, and how to close the gap.

The common reasons claims get rejected

1. No pre-authorisation. The service needed prior approval and it wasn't obtained or recorded.
2. Outside benefit limits or caps. The patient's plan didn't cover the service, or a cap was exceeded.
3. Wrong tariff or pricing. The claim amount didn't match the scheme's agreed tariff.
4. Missing documentation. The diagnosis, encounter detail or enrolee verification wasn't attached.
5. Late submission. The claim missed the scheme's submission window.
6. No follow-up. Rejected claims are never reviewed, corrected and resubmitted — so the money is just written off.

The fix is a workflow, not a spreadsheet

Most of these failures come from running HMO billing on paper or in a spreadsheet, separate from the clinical record. The fix is to make the claim part of the workflow:

• Capture pre-authorisation up front, tied to the encounter, so nothing is billed without the approval on file.
• Enforce benefit limits, caps and co-pay rules per scheme, so out-of-cover services are flagged before they become a rejection.
• Map services to each scheme's tariff so claim amounts are correct the first time.
• Generate claims in batches per scheme and track claim aging, so nothing sits past the submission window.
• Record every response — approval, part-payment or rejection — against the claim, so you can see exactly what is outstanding and why.
• Reconcile payments additively against the invoice and bill the shortfall, instead of overwriting and losing track.

How DawaHQ helps

DawaHQ builds all of this into the clinical workflow: configurable HMO and NHIS/NHIA schemes with tariffs, caps and co-pay rules; pre-authorisation capture; batch claim generation; response and rejection tracking; and additive reconciliation with shortfall billing — plus an HMO dashboard and claim-aging reports so your finance team can see the money that's outstanding and chase it.

The result is fewer rejections, faster payment, and recovered revenue that used to leak away one small claim at a time.
