What are Attachment and Radiograph Requirements for Dental Claims?

Has your dental payer ever denied a claim due to not complying with attachment and radiograph requirements?

It’s common for payers to deny claims when dental practices don’t attach complete documents and radiographs with their dental claim forms.

And this is a huge billing error!

There are certain procedures where insurance companies require documents to prove that a patient’s condition requires treatment and if it’s worth reimbursement.

And you need to master these requirements to submit clean claims and receive faster reimbursements. 

Want to know how to achieve that, and how professional dental RCM services help with that? Let’s discuss.

What are the Components of Attachment and Radiograph Requirements?

Before discussing attachment and radiograph requirements for dental payers, let’s first understand their components.
So, attachments are the documents that payers require for expensive or complex dental procedures. You may find these requirements in provider manuals, or contact the payer representative for guidance while submitting claims.

The purpose of attaching these documents to a dental claim is to prove that a treatment is really necessary for a patient’s dental condition, and it can’t be missed.

It’s because dental payers want to control their costs and reimburse only if you provide solid evidence for a dental procedure.

Payers review your documents, and if they determine the dental claim worthy of reimbursement, you’re more likely to receive your payment, making your dental revenue cycle smooth.

The most common dental claim attachments include:

• Dental radiographs
• Intraoral photos
• Periodontal charts
• Treatment narratives

Let’s discuss each of them in detail.

Dental Radiographs (X-Rays)

Radiographs are the most commonly requested attachments by dental payers. These are diagnostic images of bones, teeth, and soft tissues, which help dentists detect issues like bone loss, cavities, decay, infections, and tumors. Based on that, dentists diagnose the dental condition and propose the right treatment for it.

These radiographs can be:

• Pre-operative: These radiographs are taken before performing a procedure. These show the dental condition that is causing tooth damage and requires treatment.
• Post-operative: These radiographs are taken after a dentist has treated the patient. These show the diagnostic imaging of the teeth to check complications, evaluate treatment success, and propose healing guidelines to patients.

There are two main types of dental radiographs, which are divided into further subtypes. The main types are:
Intraoral radiographs: These radiographs provide a detailed view inside the mouth, helping check bones, jaws, and teeth. Sub-types include:

In some cases, dental insurance may also require a full mouth series (FMX), which includes multiple bitewings and periapical radiographs in a single visit to record teeth, roots, and surrounding bone structures. It helps diagnose dental conditions, which aren’t easy to detect.

• Extraoral radiographs: These radiographs capture the entire mouth in one image, helping assess parts like jaws, skulls, sinuses, and teeth. Sub-types are:

Intraoral Photos

Intraoral photos are detailed, real images of the inside of a patient’s mouth. The deep imaging helps dentists detect issues like decay and gum disease, and evaluate a patient’s dental condition to diagnose a condition and suggest a treatment. These are safer than radiographs, which are created with radiation. 

The intraoral photos not only help patients view their internal mouth, but also help practices with strong documentation for dental claims. Payers get a clear view of patients’ dental condition, which makes it easier for them to review the condition and its necessity for treatment.

Periodontal Charts

The periodontal charts are clinical records that help track and measure the health of the gums and the supporting structure around each tooth.

For complete charting, a dentist uses a periodontal probe to measure the gum pocket depth for each tooth. Dental payers like Aetna require dental providers to record six points per tooth for periodontal charts. Healthy gums are around 1-3 mm, but if their size is more than 4mm, it may indicate a dental condition, such as gingivitis or periodontitis.

The diagnosed condition helps dentists determine the need for deep cleaning to treat and cure the issue.

Periodontal charts are mostly required for periodontal procedures, like scaling and root planing (SRP), gum surgery, and periodontal maintenance.

Treatment Narratives

Narratives are concise descriptions of a dental treatment, which help the payer understand:

• Primary complaint of the patient
• Evaluation of the patient’s dental condition
• Diagnosis of the condition
• Proposed treatment for the condition

Narratives are mostly prepared by the treating dentists, who describe briefly why a dental procedure is necessary for a patient’s health, convincing payers that the treatment is important and billable for reimbursement.

What are Dental Payers’ Attachment and Radiograph Requirements?

Since documentation is an important step in the mid-revenue cycle process for dental billing, make sure that it’s complete and accurate, fulfilling your payer’s criteria.

And while each payer has their own criteria, we’ll discuss some of the common and major requirements.

Chart Notes

Some dental payers require complete chart notes, which record the complete details of a patient’s treatment. These are also known as SOAP notes, which are abbreviated as:

• S: Subjective (patient complaints)
• O: Objective (clinical findings, probing depths, radiographs)
• A: Assessment/Diagnosis
• P: Plan/treatment performed

These chart notes describe everything, including:

• Total chair time spent in treating a patient
• Complete evaluation and diagnosis of the patient
• Detailed description of all the services provided to the patient

Create templates as it reduces the need for separate chart notes, but make sure to customize phrases and wording for each chart note, as every patient’s case is different from the other.

According to the American Dental Association’s SOAP guidelines, follow these best practices for complete detail, helping protect you legally: 

• Document initial tooth conditions and track changes over time.
• Record findings at both diagnosis and treatment stages.
• Include photos when appropriate to support treatment and outcomes.
• Detail materials used (brand, lot number, conditions) for every procedure.

Diagnostic-Quality Radiographs

Most dental payers require practices to submit diagnostic-quality radiographs, which present clear imaging in high-resolution. Contrast should be good, density should be sufficient (neither too dark nor too bright), and correct angulation should be used, so the teeth are visible in their correct size.

The purpose of a diagnostic-quality radiograph is to show the complete tooth area. Among all the radiograph types:

• A periapical radiograph should show the entire tooth from crown to root apex and 2-3 mm of surrounding bone.
• A bitewing radiograph should show the crowns of the upper and lower teeth
• An occlusal radiograph should show a large area of the maxilla

It should be free of all the defects like cone cuts, film bending marks, and processing stains.

Now, a question looms here: What happens if a dental radiograph isn’t diagnostic-quality? You may need to retake the image in high-quality, so it qualifies for claim approval.

Complete and Concise Narratives

This is a point where the clinical staff and the billing team may be prone to errors. Dental treatment narratives should be complete but concise. These should neither miss any important detail nor be too lengthy and difficult for dental payers to review.

Make sure that you mention every detail, but concisely. From the patient’s dental condition and tooth number to the diagnosed condition and proposed procedure, the narrative should include all the key details related to treatment, so your payer knows what the patient came for, what was diagnosed, and what treatment was advised or performed.

The following is an example of how to write a professional narrative for a dental claim submission:

Treatment Plan

Payers require dental practices to document complete treatment plans for major dental procedures. These treatment plans comprise four steps:

1. Examining and identifying the dental condition
2. Deciding the right treatment for the patient’s needs
3. Trying alternatives before finalizing the procedure
4. Recommending the treatment to the patient

It’s only decided to proceed with the treatment if the patient agrees to it. Practices must also obtain patients’ written consent for that, which should be clearly mentioned with evidence in the treatment plan. Make sure it’s appropriate to the patient’s condition.

Once you create the complete treatment plan, document it in the patient’s record.

Correct CDT Codes

CDT coding accuracy is essential for dental claims. When you attach documents or radiographs to your claim, make sure that these match the procedure code. And, both the coding and documentation should be relevant to the procedure.

Example: An implant-supported crown (D6066) on tooth #25 requires pre-operative radiographs showing the site with missing teeth, post-operative radiographs confirming implant placement, and clinical notes detailing the procedure and abutment connection. All documentation aligns with the CDT code, verifies medical necessity, and ensures accurate claim submission for payer review and approval.

It’s the dental provider and hygienist’s job to arrange for the correct and complete documentation. But you shouldn’t worry about CDT coding. It’s the area where AADC-certified billing and coding specialists like TransDental assist your practice. 

They master payer requirements, CDT coding rules, and claim submission protocols, while also guiding you to fulfill the payer’s documentation requirements for claim approvals and faster reimbursements.

ALARA Principle

According to the American Dental Association’s guidelines, dental practices are required to follow the ALARA (As Low As Reasonably Achievable) principle to take dental radiographs. ADA states that:

• Radiographs must be taken only when necessary and determined only based on the patient’s dental history and condition.
• The suggested radiographs shouldn’t pose harm to the patient’s oral health.
• Practices should prefer using digital X-rays, which reduce radiation dose by 40-60% during radiographs.
• Patients must be wearing protective equipment, such as thyroid collars or aprons, to reduce radiation exposure.

While ALARA is mostly a clinical requirement, it is also reflected in dental insurance coverage plans, especially Medicaid, which is a state-run program, and may require practices to follow it.

For example, payers set frequency limitation rules, limiting the number of times a patient can receive diagnostic services, like a bitewing X-ray or an FMX. These may be one in three years, and may only be allowed if they are necessary to diagnose a patient’s condition.

Attachment and Radiograph Requirements for Certain Dental Procedures

Let’s review procedure-wise attachment and radiograph requirements for dental claims.

Crowns

For crown procedures, most payers require pre-operative periapical radiographs that show the full tooth, including the root apex. The radiograph must also reflect the endodontic and periodontal state of the tooth and is preferred within 6-12 months of the crown prep procedure.

Make sure that the image shows the apex. If the submitted X-ray cuts off the root tip, it can lead to a claim denial. Intraoral photographs can also be used to accompany radiographs when evidence of necessity isn’t obvious on the X-ray alone.

Root Canals / Endodontic Therapy

Root canal claims require detailed documentation. These need both pre-operative and post-operative periapical x-rays. The pre-op shows the extent of decay or infection into the nerve, while the post-op confirms the canal was fully treated to the apex.

Dental payers, like Delta Dental, list specific denial codes for missing endodontic radiographs, including:

• 570 (missing pre-op periapical images)
• 8L9 (missing post-op radiographic images of completed root canal therapy). 

If either is missing, the payer may flag the claim and request documentation, or completely deny a claim.

Tooth Extractions

Simple extractions generally require a pre-operative periapical x-ray showing the tooth to be extracted. For surgical extractions or complicated cases, like impacted third molars, a panoramic radiograph or a CBCT scan may be required, depending on payer requirements.

Periodontal Procedures

Periodontal claims are denied at a notably high rate. Delta Dental and other major payers require bitewing radiographs taken within 12 months of planned treatment that show both arches and bone levels. Importantly, visible loss of alveolar crest height beyond the normal 1-1.5mm distance to the cementoenamel junction (CEJ) must be evident on the x-rays.

Periodontal charting is also mandatory at a minimum of six probing sites per tooth and must be completed within the past 12 months. Without both the radiographic evidence of bone loss and the periodontal chart, these claims can be denied.

Anterior Composites and Restorations

Anterior composite claims may require pre-op and post-op x-rays, especially when the procedure involves significant tooth structure loss. 

Intraoral photos are highly recommended here. These photos capture surface-level damage that radiographs simply can’t show clearly.

Implants and Implant-Supported Prosthetics

Implant claims require current and dated radiographs showing the implant in place (post-service) or documentation of the projected implant placement date (pre-service). 

For implant-supported removable dentures and similar prosthetics, the same radiographic standard applies across most payers, like UnitedHealthcare, which clearly defines the requirement in its 2026 claim review guidelines.

How to Submit Documents with A Dental Claim Form?

Electronic claim submission is the preferred method for payers to accept dental claims. You can use the payer portal to submit these claims, and while you do so electronically, you can attach all the documents in the payer’s accepted size and format. 

If these are radiographs or intraoral photos, you may use any of the formats like JPG, PNG, or TIFF, depending on what your payer requires.

For clinical narratives, you may need to upload a DOC or PDF format file. Attach it to your claim submission and submit it to the payer.

And for manual claim submissions, attach the documents to the paper claim form and send it to the payer via mail or fax.

Conclusion

It’s important to fulfill dental payers’ attachment and radiograph requirements for costly or high-risk treatments like bridges, crowns, dentures, implants, SRP, and tooth extractions. These procedures aren’t simple routine cleanings or fillings, and payers require complete evidence to prove their medical necessity. 

Whether it’s 6-point probing for periodontal charts, high-resolution imaging for dental radiographs, or a complete and concise description for treatment narratives, make sure your documentation is strong and solid for the payer to approve your claim and pay what you’re owed fast.
