The insurer money nobody bills for

When an insurer pays less than the invoice, the gap is a shortfall, and often the patient owes it. How much of yours is ever actually billed?

For UK clinics that see insured patients · 4-minute read

Clinics that treat privately insured patients (Bupa, AXA Health, Aviva, Vitality, WPA and others) live with two slow leaks. Insurers pay less than invoiced, and the difference is easy to lose track of. And insurers take time to pay, so cash you've already earned sits with them for weeks.

An estimate from your inputs. Some shortfalls are written off on purpose. The real figure needs your insurer remittances joined to your invoices.

Why shortfalls slip through

And the cash that's late

Days to pay matters as much as the shortfall. If insurers take 34 days instead of 30, more of your money is sitting with them at any moment, and a slow drift is easy to miss without a monthly figure for each insurer.

How to get the real numbers

Match each insurer remittance line to its invoice by invoice number. Shortfalls with no matching patient invoice are your unbilled money; the gap between invoice date and paid date, by insurer, is your days to pay. It's a slow job in a spreadsheet, and it's one of the joins our free data check makes when you give it your remittance and invoice exports.
