How to appeal a denied dental claim

The short version

• Read the reason first. If the EOB says the payment follows the plan's design, the ADA says there is no need to appeal.³
• If you made a coding error, send a corrected claim. If you didn't, appeal when you have grounds.¹
• Appeal in writing, put the word "appeal" in the title, and send records that show why the care was needed.¹
• For employer plans under federal law, the plan must give at least 180 days to appeal. Your plan may allow more.⁴⁵

Step 1: Read the denial

Start with the explanation of benefits (EOB) or denial notice. For employer plans covered by federal law, the denial notice must include:⁴

• The specific reason for the denial.
• The plan rule the decision is based on.
• Any extra information the plan needs to complete the claim.
• The plan's appeal steps and time limits.

Dental plans count here. The Department of Labor says dental benefits, "either as part of a larger welfare plan, or as a stand-alone plan," follow the rules for group health plans.⁶

If the EOB gives no reason, the ADA says to appeal in writing. An appeal can also make the payer explain why it paid what it did.³

If the denial came on an ERA: the reason shows as standard codes, not a written note. CMS explains that each adjustment can carry up to three codes: a group code, a reason code and a remark code.⁸ The group code shows who is responsible for the unpaid amount.⁸

To see what a code means, look it up on the official lists on X12's website.⁹ If you still can't tell why the claim was cut, call the plan and ask before you appeal.

Fix it or appeal it?

Not every denial needs an appeal. Sort it first.

• Coding error on your side. Check that you used the CDT Code version in effect on the date of service, and the right code for what you did. If there's an error, send a corrected claim.¹
• Missing information. If the notice asks for something, such as a narrative or x-rays, send what it asks for. Codes that are "by report" need a narrative, or the claim may come back.¹
• Plan limits. Frequency limits, exclusions and alternate benefits are part of the plan.³ If the EOB says the payment is based on the plan's design, the ADA says there's no need to appeal. If you think the plan applied its rules wrongly, appeal.¹³
• You coded correctly and the care was needed. This is when to appeal. The ADA says to code for what you do, even if a payer asks for a different code.¹

What to send with an appeal

The ADA notes that the payer's dental consultant "may only be looking at a dental claim form." Give them a clearer picture of why you recommended the treatment.¹ Depending on the procedure, the ADA lists:

• A narrative. Include as much as you can, "even if this appears obvious to you."¹
• X-rays. For scaling and root planing, x-rays that show bone loss. Send copies, not your originals.¹²
• Periodontal charting for scaling and root planing and periodontal maintenance.¹
• Before and after photos for core buildups, along with x-rays that show the need.¹
• Anything you didn't send the first time.¹

A clear narrative covers, per the ADA:¹

• The condition of the mouth.
• The procedure you performed.
• Why extra time or material was needed.
• Anything your provider agreement requires.

Under federal rules for employer plans, you can send written comments, documents and records, and the review must take all of it into account.⁴ You can also ask for copies of the documents relevant to the claim, free of charge.⁴⁵

Deadlines and levels of appeal

Check the plan's deadline first. The ADA says to file in writing "within the time allowed by the carrier," to the department it names, in the form it requires.¹

For employer group plans covered by federal law (ERISA), the rule sets some floors:

• At least 180 days to appeal after the denial notice.⁴ The plan may give more time.⁵
• No more than two required appeals before the patient can go to court.⁴
• A new reviewer. The review can't defer to the first decision, and it must be done by someone who wasn't part of it. For decisions based on clinical judgment, the plan must consult a health care professional with the right training.⁴
• Decision time. For a claim on care already given, the plan must decide an appeal within 60 days. With two levels, it's 30 days for each.⁴

These federal rules generally cover private-sector employer plans. The Department of Labor notes exceptions for plans sponsored by government or most religious bodies.⁵ Individual plans follow other rules, so read the plan documents.

Who can appeal: the office or the patient

This matters more than most offices expect.

• The federal appeal rights belong to the patient. A plan can't block an authorized representative from acting for the patient.⁴
• An assignment of benefits usually isn't enough. The Department of Labor says an assignment generally gives the right to receive payment, not the right to appeal. Follow the plan's steps to name a representative.⁶
• In-network payment disputes may follow your contract instead. The federal rule doesn't cover a provider's request for payment under its own contract when the dispute won't affect the patient's benefits. If you can bill the patient for the unpaid amount, the request counts as the patient's claim.⁶ Check your provider manual for its dispute steps.

If the appeal is denied

1. Use every level of appeal the plan offers, with all supporting records.²
2. Ask for a peer call. The ADA suggests asking the payer's dental consultant to call you before denying, and leaving a time when the dentist is free.¹
3. State-regulated plan? If appeals don't resolve it, the ADA says to file a complaint with the state insurance commissioner that clearly lays out your case. Your state dental society can give you contact information.¹
4. Self-funded employer plan? The ADA suggests the patient raise it with the employer's benefits manager.¹
5. Ask the ADA. The ADA Third Party Payer Concierge is free for ADA members at 1-800-621-8099 or dentalbenefits@ada.org.⁷

Appeal letter outline

Follow the payer's own form if it has one. If not, this structure keeps the letter clear. It is a structure only, not legal language.

1. Title with the word "Appeal." The ADA says to put it in the title, the text and any cover letter.¹
2. Claim details: claim number, member ID, date of service, procedure codes and the date of the denial.
3. What you're asking for: one sentence, such as asking the plan to reconsider and pay the claim.
4. Why the denial should change: answer the stated reason directly. Point to the plan rule the denial cited.
5. Clinical summary: the narrative from the dentist.
6. List of what's attached: x-rays, charting, photos, the EOB.
7. Contact line: who to call and when the dentist is available.
8. Signature and, if the office is acting for the patient, the patient's signed representative form.

Keep an appeal log

One row per appeal. These columns cover what you need to follow up and report on results:

• Claim or account number

  From your practice software. Leave patient names out of shared sheets.

• Insurance company and plan type

  Employer plan, individual plan, government plan, or not sure.

• Date of service and procedure code

  What was billed.

• Date of denial and stated reason

  Copy the reason from the EOB or denial notice.

• Appeal deadline

  From the denial notice or plan documents.

• Level

  First appeal, second appeal, or complaint.

• Date sent and how

  Portal, fax or mail, with a confirmation number.

• What you sent

  Narrative, x-rays, charting, photos.

• Follow-up date

  When you will check on it next.

• Outcome and amount

  Paid, partly paid, or upheld, and the dollar change.

Over time, the log shows which payers deny which codes most. That tells you what to send with the first claim next time.

Checklist

1. Read the denial reason and the plan rule it cites.
2. Check for coding errors. If you find one, send a corrected claim.
3. Note the appeal deadline from the notice or plan documents.
4. Gather the narrative, copies of x-rays, charting and photos.
5. Get the patient's signed form if the office is appealing for them.
6. Write the appeal with "Appeal" in the title and send it the way the plan asks.
7. Log the date, method and confirmation number. Set a follow-up date.
8. If denied, use the next level, then the state insurance department or the employer.
