Failing to meet pre-authorization requirements is one of the top reasons for dental claim denials. Payer policies can change at any moment. If you don’t follow these policies, forget to obtain prior authorization for certain procedures, and submit claims, you’re highly prone to receiving a denial.
And the worst news is that you can’t appeal these denials, because pre-authorization is required before a treatment. And claim submission follows a dental procedure. So, if you miss payer approval, you’re likely to lose revenue.
Want to protect your revenue against claim denials? We’ll guide you through that, guiding on payer requirements for pre-auths and best practices for compliance. So, let’s dive in.
What are Pre-Authorization Requirements in Dental Insurance?
Each payer sets guidelines for dental practices to submit pre-authorization requests for some high-cost procedures. Payers have certain requirements that billers must follow to submit requests and obtain prior approvals. If you don’t comply, you may end up sending claims that get denied.
Want to know what payers expect for pre-auths? Investing in real-time insurance eligibility verification services helps you with that. When you verify a patient’s coverage, you can check if the procedure requires pre-authorization. If there are any further requirements, contact the payer representative or check the provider manual for details, and follow them for pre-auth requests.
Which Procedures Require Pre-Authorization?
Insurance companies require dental billers to obtain pre-authorization for certain dental procedures, which are high-cost. Since reimbursement rates are high for these procedures, payers don’t reimburse simply because you bill a claim. They need proper evidence to review if the treatment is valid for the patient’s health and can be reimbursed.
Due to that, payers require practices to seek prior approval first for some dental claims. The most common procedures are bridges, crowns, dentures, implants, scaling and root planing, and tooth extractions.
While this list is common among most payers, it’s not universal, as each payer may have different criteria for pre-authorization. So, make sure to check your payer’s criteria for pre-authorization before requesting that and submitting claims.
Common Pre-Authorization Requirements in Dental Claims
Let’s review some common pre-auth requirements for most dental claims.
Accurate CDT Codes
You need to verify a dental procedure’s CDT code before you request its pre-authorization. The CDT code is the basis for insurance companies to identify a procedure on a dental claim. So, when you submit a request for pre-auth, add the relevant CDT code for the proposed treatment.
Example: A patient has lost a tooth due to decay, and an abutment-supported ceramic or porcelain crown is required to cover the tooth loss. The CDT code is D6058. Clearly mention the CDT code on the pre-authorization request form, along with all the other details. But make sure the CDT code is correct according to the ADA’s CDT coding update in 2026 and your payer’s updated provider manuals.
Some payers have their pre-authorization forms, which require billers to enter details like the relevant CDT code and other information.
Procedure-Specific Requirements
Each CDT code has its requirements. Some payers may require you to provide additional details for pre-auth requests on each procedure. Let’s break down the examples in the table below:
| Procedure Category | Requirement | Purpose |
|---|---|---|
| Implants | Missing tooth history | Show if the tooth is actually missing |
| Bone evaluation | Check if the bone can support an implant | |
| Treatment sequence | Show planned treatment steps | |
| Orthodontics | Case score | Show braces are needed to align the patient’s teeth correctly |
| Malocclusion index | Show how severe the problem is | |
| Age verification | Check if the patient’s age is suitable for the treatment | |
| Prosthodontics | Missing tooth duration | Show how long the tooth has been missing |
| Prior prosthetic history | Check if the treatment was done before |
Consult your payer’s provider manuals to see the documents required for pre-authorization on each claim.
Evidence for Medical Necessity
Insurance companies require strong evidence to prove that a dental procedure is important for a patient’s health. They may be convinced to give prior approval and reimburse only if you can prove the necessity.
Complete documentation, like dental radiographs and intraoral photos, helps payers review a patient’s dental condition and determine if treating it is important and is worth reimbursement.
Periodontal charts are required for procedures, such as an SRP or periodontal maintenance. You can use them for periodontal procedures if the payer requires you to obtain a pre-auth for submitting a claim.
Tooth-Specific Details
Dental payers require complete tooth-specific details to evaluate the patient’s condition, determine the exact tooth location requiring treatment, and approve or deny the pre-auth request.
So, when you submit a pre-auth request, make sure to add all the necessary details related to a tooth. These include:
- Tooth number for procedures like core buildup, crowns, root canal therapy, and tooth extraction
- Surface information for restorative procedures like amalgam, composite filling, and crown buildup
- Oral cavity quadrant for deep cleaning procedures like scaling and root planing
This information helps the payer check whether a certain tooth has already received the treatment and if the frequency limitation rules permit more treatments on that tooth.
The tooth-specific details also assist payers in reviewing the diagnostic proofs, like dental X-rays and intraoral photos, to see the affected area and decide if the condition needs treatment.
Note that each payer’s policy may vary by procedure, but these details are almost always important in every pre-auth request.
Timely Pre-auth Requests
You shouldn’t delay preauth requests. Submit the request at least 10-14 days before the treatment. Payers need time to review your requests, check the documents, and approve them if they’re worthy of the patient’s treatment.
Some payers don’t define any deadlines for preauths, but require the requests before submission, while mentioning their process. An exception to this is DentaQuest Texas, which mostly responds to preauth requests within three business days. In that case, you must send the pre-auth request at least 7-10 days before the proposed treatment date.
With a proper pre-auth request, you get timely approvals and a pre-authorization number, which you can use for your claim submission.
Note: Pre-authorization isn’t a guarantee of payment. Your reimbursement is decided after you submit your claims to the insurance company.
Treatment Plan
Some dental payers require complete treatment plans for pre-authorization requests to know how you’re planning to treat the patient. These plans contain all the details related to the treatment, such as the:
- Proposed dental procedure with relevant CDT codes
- Affected tooth number and area
- Billable fee for the procedure
- Radiographs and/or clinical notes to prove the patient’s condition and justify the necessity for the treatment
A strong treatment plan is likely to win pre-auth requests and get the pre-authorization number for your ADA dental claim form.
Best Practices to Follow Dental Pre-Authorization Requirements
Check the Payer’s Pre-Auth Requirements
Dental payers set the pre-auth requirements for certain CDT codes and publish their details on their online provider manuals. You may also check them while verifying a patient’s coverage, as requirements may vary for each patient. However, general pre-auth requirements work in most dental claims.
An example is the Minnesota Health Care Programs (MHCP), which publishes its pre-authorization requirements. MHCP provides its complete list of CDT codes that require pre-authorizations, and also mentions the documents required for each category.
If you check the Prosthodontics section in this guide, MHCP has mentioned its requirements to add these supporting documents to pre-authorization requests. The documents include:
- Tooth charting: A record of all teeth, existing fillings/crowns, cavities, other dental issues, and the expected outlook for the remaining teeth to justify the treatment.
- Periodontal charting: A detailed gum exam showing attachment loss, gum recession, bleeding, tooth mobility, tissue condition, and tartar levels, including a diagnosis and outlook for gum health.
- Treatment plan: A complete plan addressing ongoing problems like infections, cavities, gum issues, and overall oral function.
- Imaging: Copies of X-rays, scans, or photos showing the teeth and gums involved, clearly labeled with the patient’s name and date. Billers must not send original documents
So, make sure when you’re submitting pre-auth requests, check your payer policies and reimbursement rules for each procedure. It helps you find out what they require in these requests and how they approve them for claim submissions and possible reimbursements.
Submit Electronic Pre-Auth Requests
Electronic pre-authorization processes are faster and more efficient than outdated and manual processes. All fields are entered within minutes, and documents are attached soon. It takes just one tap to send the request to the payer by adding CDT codes, the patient’s data, and insurance membership details. By integrating automatically with the patient’s EHR, records can be fetched quickly.
Responses also come faster in most cases. If your payer uses an automated system to check and respond to pre-auth requests, it takes them just a few seconds or minutes to determine whether they’ll approve the request or deny it.
The quick process saves time for your billing staff. If the payer approves it and provides you with the pre-authorization number, you can treat the patient soon, submit the claim fast, and most possibly recover payments quickly.
Outsource Pre-Authorization Process
Checking which procedure requires pre-authorization, arranging the relevant documents, and submitting requests is a time-consuming process. And, if not done right, it can lead payers to deny your pre-auth requests.
If you want to win your pre-auths, you need more than payer policy compliance. You need a smart approach to manage all these tasks with expert support, and you can get that if you outsource your RCM processes, like pre-auth requests, to revenue cycle specialists like TransDental.
These specialists know policies for insurance companies in every state, and use that expert knowledge to submit pre-auth requests by attaching all supporting documents and fulfilling payer requirements.
With that, a practice gets a quick response and is more likely to receive a pre-authorization number if all the details, documents, and requirements are correct.
So, what are you waiting for? Partner with reliable RCM partners and start submitting pre-auth requests to strengthen your claims and maximize reimbursements.
Conclusion
Obtaining prior authorization from insurance companies is a must for certain dental procedures. But, you can achieve that only if you fulfill your payer’s requirements. Attach all the documents your payer needs to know the necessity for a procedure, follow your payer’s guidelines in provider manuals, and use automation and software to submit fast and efficient pre-authorization requirements for fast responses and smooth results. A strong pre-authorization impacts your claim reimbursements and helps recover payments fast.
