What to do when an insurer underpays a claim

A shortfall often arrives as a quiet number on an explanation of benefits. The claim was paid. The check is smaller than the documented loss. Staff file it because the carrier name looks familiar and the claim number matches.

The work is to put the policy, the original claim, the estimate or invoice, and the explanation of benefits on the same table. Coverage, deductibles, and pricing are different problems. Mixing them in one paragraph is how an appeal gets closed as incomplete.

This guide is educational. Telvon does not guarantee a supplemental payment. We take a documented shortfall and pursue it with the carrier on your behalf.

Read the explanation of benefits first

Read the explanation of benefits line by line. Circle every code, reduction, and unpaid service. A highlighted EOB is more useful than a letter that says the check feels short.

Typical reductions look like this:

A deductible or coinsurance applied in a way that does not match the policy.
A service paid at a lower allowed amount than the documented charge.
A denial code that does not match the record of what was performed.
A duplicate or split payment that still leaves a documented gap.
An exclusion applied to a service the policy appears to cover.
A catch-all reduction that still needs a documented reply.

If a line was denied, name the denial code and attach the page of the policy or the original claim that answers it. Guessing why the carrier paid short is how an appeal turns into a complaint.

Separate coverage from pricing

Appeal windows are short. Missing one is often treated as acceptance of the payment, not as a delay you can explain later. Put the printed window on a calendar the day the EOB arrives, even if you are still gathering operative notes or invoices.

Track these dates in writing:

The date on the explanation of benefits that first showed the shortfall.
The date you requested statements, receipts, and delivery proof.
The date the carrier last asked for more documents.
Who on your team is authorized to speak for the business.
Where the finished PDF packet will live, with a file name the carrier can open.

Do not wait for a perfect packet if the appeal window is about to close. Send a complete appeal with the exhibits you have, note what is still coming, and follow with the missing record only if the carrier asks.

Gather the original claim packet

Carriers read documents. They do not reconstruct a claim from a voicemail to the broker. A numbered packet with the EOB, the original claim, and the policy page beats a long explanation that never cites a line.

Collect, in this order:

The original receipt or invoice, with the same amount as the charge.
Proof of delivery, pickup, or service completion.
The signed ticket, terms, or booking confirmation.
Visit notes and coding that show the service billed.
The policy page that covers the denied or reduced service.

If an operative note or invoice is missing, say so. Do not invent a code or a date of service. A reviewer who catches a fabricated exhibit will stop reading the rest of the appeal.

Mark every unpaid or reduced line

One page of facts, then exhibits. Lead with the claim number, the date of loss or service, and the dollar difference between the documented amount and the payment. Do not open with how long you have been a customer.

The appeal should answer:

What was sold, and on which date.
How the visit was documented and coded.
Whether goods or services were delivered.
Whether a refund was already issued.
Which exhibit proves each point.
What you are asking the carrier to do: pay the documented shortfall.
How to reach the person who assembled the file.

Number the exhibits. A reviewer who cannot find the EOB line in thirty seconds will not hunt for it across a forwarded email chain.

Write to the carrier, not the broker

Send only records that belong to this claim. Extra screenshots of unrelated patients, marketing pages, or last year's payments slow the review.

Merchant copy of the receipt or invoice.
The policy page, fee schedule, or authorization that set the expected payment.
Shipping label, pickup log, or signed work order.
Policy language the carrier cited in the explanation of benefits.
Prior refund or replacement if one already happened.

Do not attach a letter that only says the carrier underpaid you. Write to the carrier's appeal address, not only the broker. Brokers can help, but the clock runs on the carrier's letter.

Keep the appeal window on a calendar

One authorized person should speak for the practice or the business. Mixed stories from the front desk, the biller, and the owner look like confusion, not proof.

Give that person:

A written authorization to contact the carrier on your behalf.
The claim number, policy number, and date of service or loss.
A single packet, not a chain of forwarded emails.
A record of every call: date, name, and what was requested.
A rule: no one else calls the carrier about this claim.

If you hire Telvon, that authorization is the work. You do not sit on hold with a carrier queue while the practice is seeing patients. Telvon still needs the EOB, the original claim, the policy pages, and a written mandate.

What the carrier usually asks for

Sending the appeal is not the end. Carriers ask for more records, issue a partial supplemental, or stand on the original payment. Silence is often read as acceptance of whatever they last paid.

Keep a log of:

The date the packet was uploaded or mailed.
Confirmation numbers from the portal.
Any request for more documents, with the due date.
The decision letter, even if it is a denial.
Whether a remaining unpaid balance on that claim is still open.

Store the log with the packet. If you later hire an advocate, that log is the first thing they need.

When a shortfall is a coding issue

A denial is not always the last word. It is also not a cue to invent a new diagnosis story. Read the written reply. If they paid the wrong line, say which line remains open and attach the same exhibit again.

Read the reason the carrier gave, not the one you hoped for.
Check whether the policy still has an open appeal window.
Send only the missing exhibit, not a rewritten argument.
If the window is closed, stop calling. The file is done.
Keep the packet. Patterns across cases matter more than one loss.

Telvon will not tell you a carrier always issues a supplemental check. Some files close with the original payment standing. Deductibles, exclusions, and coding that does not match the record are common reasons.

When it is a coverage dispute

Carriers look for a dated, specific appeal. Vague complaints about being underpaid rarely move a claims desk. The letter should name the claim, the EOB lines, and the documented difference.

Keep:

The claim number and the policy or member number.
Each reduced or denied line, with the EOB wording next to it.
The date the charge posted and the date the notice arrived.
The billed amount, the paid amount, and the difference you are appealing.
The deadline printed on the notice, in writing, on a calendar.

Treat the file as a calendar problem first. Appeal windows expire whether you feel ready or not. A complete letter sent on time is stronger than a perfect packet that arrives after the carrier has closed the claim.

Do not promise a supplemental check

A complete shortfall file usually includes:

The original invoice or receipt.
Proof of delivery, service, or attendance.
The original claim and the explanation of benefits for that date of service.
Your refund or cancellation policy as it stood at the time.
Correspondence that shows they knew the charge.
A short cover note that states the request.

None of this guarantees a supplemental payment. It puts the carrier in a position to review documented facts against the policy they issued. Results depend on coverage, coding, and whether the appeal window is still open.

A shortfall file checklist

A coding issue and a coverage dispute are not the same letter. If the service was covered but billed under the wrong code, the file needs the corrected coding and the record that supports it. If the carrier says the service was never covered, the file needs the policy page, not a better invoice.

After you send the appeal, document:

The date and channel you used to submit.
The exhibit list you attached.
Any items you could not produce in time.
A copy of the full PDF stored off the carrier portal.
The confirmation number or reference the carrier gave you.
The next date you are expected to hear back.
Who on your team owns follow-up if the file is silent.

Do not tell a patient or a partner that a supplemental check is coming. Telvon will not promise a recovery amount or a timeline. Ask for the arithmetic difference between the documented loss and the payment, line by line.

After you send the appeal

Keep a log of:

Dates: every notice, call, and upload.
Names: who you spoke with and what they asked for.
Status: open, submitted, or closed.
Owner: the person authorized to speak for the business.
Next date: the next deadline or expected reply.
Ask: what you want the carrier to pay.

What Telvon will not do

Hold, manage, or transfer funds.
Process payments or serve as a financial institution.
Provide legal advice or appear as counsel.
Promise a recovery amount, outcome, or timeline.
Replace your bank, processor, or insurer.
Send promotional text messages.

Telvon is an advocate. You remain the claimant or the practice of record. Telvon does not hold funds, does not issue the check, and does not practice law. The carrier still has to post any supplemental payment.

When to hand the file over

If you are missing the calendar, the EOB, or the time to write an appeal the claims desk will read, that is the point to authorize an advocate. Hand over the policy pages, the original claim, the payment, and a written mandate.

Telvon investigates the shortfall, assembles the packet, and communicates with the carrier on your behalf. You stay the claimant named on the policy. Telvon does not hold the money and does not replace your accountant or counsel.

Start a case when the shortfall is large enough, or repeated often enough, that sitting in a carrier portal is costing more than the work of handing the file over. Telvon will not promise a recovery amount or a timeline.
