Chasing insurer shortfalls: a process that actually gets the money in

A shortfall is simple to describe and easy to ignore. You invoice an insurer for a treatment. The remittance arrives and it is less than the invoice. The difference sits there, usually small, usually not worth a phone call on its own, and usually never chased.

One shortfall does not matter. A year of them does. Most clinics I have worked with are surprised by the total when someone finally adds it up, because it never arrives as a single painful number. It leaks.

Why shortfalls happen

Almost every shortfall comes down to one of five things, and the reason matters because it decides whether the money is recoverable.

The fee schedule. The insurer pays its agreed rate for that treatment, not your list price. If you are not on a schedule for that insurer, or your fees have moved and theirs have not, every invoice will underpay by the same amount. This one is not a mistake, and chasing it will not work. It is a pricing decision you need to make deliberately.

The patient's excess. The insurer deducts the excess and expects the patient to pay it. The money is not missing. It has simply moved from the insurer to the patient, and if nobody invoices the patient, it stays uncollected.

Benefit limits and sessions used up. Policies cap what they will pay, whether by number of sessions, by a monetary limit, or by policy year. Once the cap is hit, the balance becomes the patient's. This is the shortfall that most often goes unnoticed, because the treatment carries on as normal while the funding quietly stops.

Authorisation problems. A missing authorisation number, an expired one, or treatment that went beyond what was authorised. Some of this is recoverable if you act quickly and the insurer will accept a retrospective authorisation. Some of it is not.

Detail mismatches. The wrong treatment code, a date that does not match the authorisation, a practitioner not registered with that insurer, or a policy number with a digit out. These are the most recoverable shortfalls of the lot. They are also the most annoying, because the work was done properly and the money is being withheld over a typo.

Why they do not get chased

Not because clinics do not care. Because chasing a shortfall requires you to notice it, work out which of the five reasons applies, and then do something specific about it. That is fifteen minutes of concentration per item, and it competes with patients.

So the remittance gets glanced at, the total looks roughly right, and it is filed. The gap only becomes visible at year end, by which point the insurers have moved on and so has everybody's memory of the case.

A process that works

The fix is not working harder on remittances. It is doing the same four steps every week so nothing ages.

1. Reconcile line by line, not in total

Match every remittance line to the invoice it relates to. Totals hide everything. A remittance that looks correct overall can contain one fully paid claim and one that paid nothing.

2. Give every gap a reason

Assign each shortfall to one of the five causes above. This is the step that turns a vague pile of underpayments into a list where each line has an obvious next action. Fee schedule differences get accepted and reviewed at renewal. Excesses and exhausted benefits get invoiced to the patient. Authorisation and coding problems get queried with the insurer.

3. Act by category, in a single sitting

Batch the work. All the patient invoices at once. All the insurer queries at once. Chasing is much faster when you are not switching between different kinds of thinking, and insurers are easier to deal with when you are querying several claims in one conversation rather than one at a time across a month.

4. Keep a ledger

One place that records what was invoiced, what was paid, what the gap was, why, and what happened next. Without it you cannot see patterns, and patterns are where the real money is. If the same insurer underpays for the same treatment every time, you do not have a chasing problem. You have a fee schedule to renegotiate, and that is worth far more than the individual claims.

Stopping them at the front end

Most shortfalls are created before the treatment happens, not after.

• Check cover and authorisation before the first appointment, not after the invoice bounces.
• Record the policy number, authorisation number and any session limit somewhere you will actually see it again.
• Tell the patient in plain terms what their policy covers and what they will owe. An excess is a much easier conversation before treatment than three months afterwards.
• Watch the session count as it runs down, so the last funded appointment is a decision rather than a surprise.
• Invoice promptly. Everything gets harder with age, and some routes close entirely.

When to let one go

Some shortfalls are not worth the time it takes to chase them. If the amount is small, the cause is a fee schedule difference, and the insurer has already confirmed its position, write it off and put the energy into the fee schedule instead.

The point of the process is not to recover every last pound. It is to make sure the decision to let one go is a decision, rather than something that happened because nobody looked.

What this really comes down to

Clinics do not lose this money because they are bad at negotiating with insurers. They lose it because reconciliation is the job that always gets bumped, and because a small gap never feels urgent enough to interrupt a clinical day.

Anything done weekly, by someone whose actual job it is, stops leaking. There is no cleverer answer than that.
